When I was about 10 years old, I was given an electric motor kit for Christmas. I had to wind a length of insulated copper wire on the rotor, put together the commutator, and install a small U magnet. I enjoyed the construction experience and with some parental assistance figured out how it worked. Ever since then, I have been curious about these simple artifacts of technology, and this article discusses some of them that I have met in my scientific travels. The small electric motor is a simple piece of technology that is based on mechanics, electricity, and magnetism and is a good mechanism for drawing students into physics.

Direct current (DC) motor speed control is useful. Speed can be modified based on needs and operations. DC motors cannot control their speed. To control the DC motor’s speed, a dependable controller is needed. The DC motor speed will be controlled by a fuzzy logic proportional integral derivative controller (FLC-PID). The DC motor circuit’s electrical and mechanical components have been modeled mathematically. Ziegler-Nichols is used to tune the PID controller’s gain parameters. The FLC controller employs 3×3 membership function rules in conjunction with the MATLAB/Fuzzy Simulink toolbox. Real hardware was attached to the simulation to evaluate the DC motor speed control using the fuzzy logic PID controller. DC motors with FLC PID controllers, FLC controllers, and DC motors alone will be compared for the transient response. The DC motor with an FLC PID controller performed better in this study.

In this study, the potential usage of hybrid nanofluids for brushless direct current (BLDC) motor cooling was compared. Due to their efficiency, durability, and small size, brushless direct current (BLDC) motors are a type of electric motor that are frequently employed in electric vehicles (EVs). In order to maintain appropriate operating temperatures and ensure long-term durability, cooling systems must be taken into account throughout the design of brushless direct current (BLDC) motors. Because excessive heat can shorten a motor's lifespan and affect its performance, effective cooling is crucial. Systems for cooling liquids need more parts and upkeep than those for cooling air. taken into account to get the maximum cooling effectiveness. The effectiveness and dependability of the liquid cooling system are greatly influenced by the system's correct design and implementation, including hose routing, sealing, and coolant choices. There are several approaches to improve a BLDC motor's hybrid nanofluid/nanofluid cooling system. In order to achieve the highest cooling efficiency, fluid flow velocity, nanoparticle concentration, and cooling system design should all be carefully taken into account.

Permanent-magnet brushless direct-current motors are easy to maintain, compared with direct-current motors. Therefore, they are attracting attention. In this paper, the authors discuss a non-salient pole brushless direct-current motors. Usually, the quadrature armature current which contributes to torque generation is supplied in this motor. But, in this case that the source voltage cannot be increased by supplying the direct armature current, that is, equivalently field weakening, a quadrature armature current can be increased. Consequently, the motor torque increases. In the case that the load characteristics are settled, the motor torque can have a maximum Tm by adjusting a direct armature current. At this time the rotational speed and output are maximum also. Tm changes with the change of the motor parameters. Consequently, the motor parameters which maximize Tm are optimal. In this paper, the authors have clarified an optimal parameter determination method considering by the load torque-speed characteristics and, armature resistance by the power factor, and efficiency where the motor has optimal parameters and generates the maximum output. Furthermore, the theory obtained has been confirmed experimentally by the authors.

Direct current motors are used for blower fans as well as for many other systems in vehicles. In this study, it was suggested to use an asynchronous motor instead of the direct current motor for the blower fan. Therefore, an induction motor driver was designed. The purpose of designing this driver was to allow the use of asynchronous motors instead of the brushed direct current motors utilized in automotive ventilation systems. Power and control circuits were designed. A three-phase variable frequency voltage was obtained using an inverter circuit designed with metal-oxide-semiconductor field-effect transistor semiconductor elements from the direct voltage. The voltage/frequency control method was applied to the induction motor. The power circuit was designed using three npn-type and three pnp-type metal-oxide-semiconductor field-effect transistors, in order to reduce the number of independent sources. The direct current motors generally used in automotive ventilation systems have 12 V operating voltage, so the driver was designed to be used in the 12–18 V range. In this study, the alternating current driver was used for a 90 W asynchronous motor and drive at 12 V and 18 V variable input voltage values. The dsPIC33fj32mc204 microcontroller was used to achieve variable frequency and speed control.

ABSTRACTBrushless DC motors or commonly known as BLDC motors are starting to be widely used in the automotive and industrial fields compared to three-phase induction motors. This is because the advantages of BLDC motors are high efficiency, large torque, and easy maintenance. Some drive systems that use BLDC motors require a constant motor speed. However, when the drive system is given more load, the speed will decrease. Therefore, we need a motor speed regulation so that the speed becomes constant even though it is given an overload. There are many ways to adjust the speed of a BLDC motor, one of which is using the Field Oriented Control method because it can adjust the field current and armature current separately. From the simulation results, the speed of the BLDC motor using the FOC method in the loaded condition, showed a better response by producing a steady state of 1494 rpm, a rise time of 0.5192 s, a settling time of 0.6362 s while not being given a load, a steady state of 1504 rpm and, a rise time of 0.533 s and a settling time of 0.64 s.ABSTRAKMotor Brushless DC atau biasa dikenal dengan motor BLDC mulai banyak digunakan pada bidang otomotif dan industri dibandingkan dengan motor induksi tiga fasa. Hal ini disebabkan karena kelebihan dari motor BLDC adalah memiliki efisiensi tinggi, torsi yang besar, dan perawatan mudah. Beberapa sistem penggerak yang menggunakan motor BLDC membutuhkan kecepatan motor yang konstan. Akan tetapi sistem penggerak tersebut ketika diberi beban lebih maka kecepatan akan menurun. Oleh karena itu dibutuhkan suatu pengaturan kecepatan motor agar kecepatan menjadi konstan walaupun diberi beban lebih. Banyak cara untuk mengatur kecepatan motor BLDC salah satunya adalah menggunakan metode Field Oriented Control karena dapat mengatur antara arus medan dan arus jangkar secara terpisah. Dari hasil simulasi didapatkan kecepatan motor BLDC menggunakan metode FOC pada kondisi berbeban, menunjukkan respon yang lebih baik dengan menghasilkan steady state yaitu 1494 rpm, rise time 0.5192 s, settling time 0.6362 s sedangkan tidak diberi beban didapatkan steady state sebesar 1504 rpm dan, rise time sebesar 0,533 s dan settling time sebesar 0,64 s.

Abstract In this paper, a non-invasive method of early fault diagnostics of electric motors was proposed. This method uses acoustic signals generated by electric motors. Essential features were extracted from acoustic signals of motors. A plan of study of acoustic signals of electric motors was proposed. Researches were carried out for faultless induction motor, induction motor with one faulty rotor bar, induction motor with two faulty rotor bars and flawless Direct Current, and Direct Current motor with shorted rotor coils. Researches were carried out for methods of signal processing: log area ratio coefficients, Multiple signal classification, Nearest Neighbor classifier and the Bayes classifier. A pattern creation process was carried out using 40 samples of sound. In the identification process 130 five-second test samples were used. The proposed approach will also reduce the costs of maintenance and the number of faulty motors in the industry.

In this paper, a new speed control algorithm for a permanent magnet DC motor which does not require implementation of the angular speed sensor is presented. Three steps are performed to develop the control system: design of speed tracking control algorithm assuming the speed measurement; design of speed observer; design of sensorless speed control algorithm based on the principle of separation. Information about speed is taken from the speed observer using the motor current value. The stability of the composite system dynamics consisting of three subsystems (the speed regulation loop, current regulation loop, and speed observer) is analyzed. The feedback gains tuning procedure for decoupling of three subsystems is given. The simulation results show that the dynamic performance of the designed system is similar to the performance of the system with angular speed measurement. The resulting closed-loop system has structural robustness properties with respect to parametric and coordinate disturbances. References 12, figures 2.

Proportional integral(PI) controllers is widely used in direct current(DC) motor controlling in factories, requiring tuning of their parameters to achieve optimal performance. New tuning techniques may be developed with the aid of research, which can speed up and simplify the tuning process. This work examined the use of PI controllers to regulate the speed of DC motors. TinkerCad modelling and Falstad circuit simulation are used to simulate the circuit model. Two well-known methods, step response and root locus, were implemented and assessed using Octave Online. Results demonstrate that, provided the KP value is not excessively high, increasing KP can enhance the stability of the DC motor close-loop system. The goal of the research is to balance the system's oscillation and stability while determining the appropriate KP value for the PI controller in this closed-loop system. This research uses octave online to analysis the root locus and close loop positions in pole-zero maps and creates the step responses of the system with different parameters of the PI controller.

Direct Current (DC) motors are widely used in industrial applications. The limited use of brushed models in some areas has brought Brushless Direct Current Motors (BLDC) to the fore. The constant need for maintenance of brushed type motors creates a disadvantage in variable conditions and in areas that are used continuously. For this reason, brushless DC motors have a wide range of uses. Brushless DC motors stand out with their high-performance values. Brushless DC motors with outer rotor type are used in applications that require high torque and inertia. The fact that electrical machines have moving parts and the computational complexity created by these parts have led electrical machine designers to alternative ways such as software and simulation programs where the results can be predicted. In this paper, a Brusgless Permanent Magnet Direct Current motor (BLPMDC) was designed and analyzed. The obtained speed, efficiency, torque, and air gap flux distributions were examined and the results were compared with literature for the motor type. In this study, applications were made to examine the effects of design parameters such as rotor structure, rotor position, magnet arrangement and materials used in the structures on the efficiency and output power of the motor. Efficiency-speed and power-speed values were obtained for different structures and features of the engine. The results obtained are compared with each other and presented in the article in the form of graphs and tables.

The progress in material and manufacturing technologies enables the emergence of new research areas in electromagnetic actuator applications. Permanent magnet (PM) linear motors are preferred to achieve precise position control and to meet the need for high dynamic forces in the seismic shake tables that are used in analyzing reactions of structure models. The design approaches on the linear motors used in the seismic shake tables may vary depending on the desired force, stroke and acceleration values. Especially, the maximum width, the maximum depth, the maximum linear motor length in longitudinal direction and the maximum travelling distance parameters are the primary design criteria in seismic shake table drive systems. In this paper, a design approach for a linear PM brushless direct current (BLDC) motor with high force/volume, force/weight and force/input power ratios is developed. The design was analyzed using two-dimensional (2D) and three-dimensional (3D) finite element method (FEM) approaches through the ANSYS Maxwell software. The mathematically designed linear BLDC motor was manufactured and subjected to displacement, acceleration and force tests that are used in seismic analyses. The results of the experimental tests validate the convenience of the proposed design approach and the selected parameters.

Switched reluctance motors are among the finest competitors to induction motors. It is a well-liked choice because of its durability, brevity, straightforward design, and superior torque to mass ratio. Currents in the stator winding of a switching reluctance motor have a direct impact on the torque generated. A large negative voltage must be offered in order to quickly stop the current while it is working in the demagnetizing phase. This research work analyzes the C-dump converter’s design. The C-Dump converter makes it possible for the phase winding to be rapidly demagnetized and magnetised, which prevents the motor from being used in the generating state. Switched reluctance motors demonstrate a variety of converter topologies for adjusting speed, power, and operation. Additionally, it frequently makes use of the energy that has accumulated in the phase winding and can be returned to the source. Some modified C-Dump converter topologies can utilise this stored energy to bypass the motor’s next phase winding.

Smoothly speed range changing, easily speed controlling, and swiftly dynamic response for load torque changing are the main merits which are delivered by direct current (DC) motors. They are also distinguished by their versatility. All these characteristics make the DC motors suitable candidates for various applications. An accurate high-speed control with a good dynamic response, would be of demand for many applications of the DC motors. Controlling the speed of motors using conventional systems is one of the most important method that is adopted and it can be more efficient when used with electronic power devices to control the output voltage. Hence, this paper introduces an efficient proportional integral (PI) speed controller for DC motor fed by direct current-direct current (DC-DC) convertor, which is switched by pulse-width modulation technique. MATLAB/Simulink environment is used to build the whole system. Two operation scenarios have been conducted including constant load with variable speed and variable load with constant speed.

Technology that is growing rapidly and innovations that have sprung up in the electrical field today are driving the use of electricity as a source of energy to do work. Electric motor is one component that is very popular in the industrial world and households that are useful to human life. In addition to DC motors and induction motors, there are also 3 phase brushless direct current (BLDC) motors which are a type of synchronous motor where magnetic fields are produced by rotor and stator at the same frequency. The rotor is a moving part of the brushless direct current motor which is a place of permanent magnet called a pole. This paper discusses the performance of brushless direct current 3 phase axial flux motors with different diameters of neodymium type permanent magnets. Tests carried out using neodymium permanent magnets with diameters of 15mm x 2mm and 20mm x 2mm were tested without using a load and using load. The parameters used in testing motor performance include speed, torque, and motor power with a source voltage of 12V, 16V, 20V, and 24V. The test results shows that the speed value of a BLDC motor using permanent magnets with a size of 20mm x 2mm is greater than that of permanent magnets of 15mm x 2mm. The same thing applies to the value of the power produced while, for the value of torque when the motor uses a permanent magnet of 15mm x 2mm will be greater than that of a motor using a permanent magnet of 20mm x 2mm.

This paper presents a design and analysis of multi-phase brushless direct current (BLDC) motor for electric vehicles (EV). In this work, hub-wheels having 110Nm, 900rpm rated values have been designed for the proposed EV. This EV can produce 440 Nm without using transmission, differential and other mechanical components which have very high losses due to the mechanical fraction. The motors to be used in the EV have been designed as 3-, 5- and 7-phase by Infolytica/Motor Solve Software to compare their performances at the same load conditions. The same rotor geometry has been utilized for the motors. However, slot numbers and dimensions of the stator have been determined by considering the motor phase number. Performance curves of phase-currents, output powers, torques, efficiencies and power factors have been presented for these motors at the same operating conditions. It can be possible to use lower power switches in motor drive system thanks to the phase current reduction since the phase currents decrease proportionally to motor phase number. This work shows that the multi-phase BLDC motors are a good alternative in order to obtain lower torque and lower power inverter structure than the 3-phase BLDC motors which are used as standard.

This study presents the tilt integral derivative (TID) controller technique for controlling the speed of BLDC motors in order to improve the real-time control of brushless direct current motors in electric vehicles. The TID controller is applied to the considered model to enhance its performance, e.g., torque and speed. This control system manages the torque output, speed, and position of the motor to ensure precise and efficient operation in EV applications. Brushless direct current motors are becoming more and more popular due to their excellent torque, power factor, efficiency, and controllability. The differences between PID, TID, and PI controllers are compared. The outcomes demonstrated that the TID control enhanced the torque and current stability in addition to the BLDC system’s capacity to regulate speed. TID controllers provide better input power for BLDC (brushless DC) drives than PI and PID controllers do. Better transient responsiveness and robustness to disturbances are features of TID controller design, which can lead to more effective use of input power. TID controllers are an advantageous choice for BLDC drive applications because of their increased performance, which can result in increased system responsiveness and overall efficiency. In an experimental lab, a BLDC motor drive prototype is implemented in this study. To fully enhance the power electronic subsystem and the brushless DC motor’s real-time performance, a test bench was also built.

This paper comprises the design, analysis, experimental verification and field weakening performance study of a brushless direct current (BLDC) motor for a light electric vehicle. The main objective is to design a BLDC motor having a higher value d-axis inductance, which implies an improved performance of field weakening and a higher constant power speed ratio (CPSR) operation. Field weakening operation of surface-mounted permanent magnet (SMPM) BLDC motors requires a large d-axis inductance, which is characteristically low for those motors due to large air gap and PM features. The design phases of the sub-fractional slot-concentrated winding structure with unequal tooth widths include the motivation and the computer aided study which is based on Finite Element Analysis using ANSYS Maxwell. A 24/20 slot–pole SMPM BLDC motor is chosen for prototyping. The designed motor is manufactured and performed at different phase-advanced currents in the field weakening region controlled by a TMS320F28335 digital signal processor. As a result of the experimental work, the feasibility and effectiveness of field weakening for BLDC motors are discussed thoroughly and the contribution of higher winding inductance is verified.

BLDC motors are characterized by electronic commutation, which is performed by using an electric three-phase inverter. The direct control system of the BLDC motor consists of double loops; including the inner-loop for current regulating and outer-loop for speed control. The operation of the current controller requires feedback of motor currents; the conventional current controller uses two current sensors on the ac side of the inverter to measure the currents of two phases, while the third current would be accordingly calculated. These two sensors should have the same characteristics, to achieve balanced current measurements. It should be noted that the sensitivity of these sensors changes with time. In the case of one sensor fails, both of them must be replaced. To overcome this problem, it is preferable to use one sensor instead of two. The proposed control system is based on a deadbeat predictive controller, which is used to regulate the DC current of the BLDC motor. Such a controller can be considered as digital controller mode, which has fast response, high precision and can be easily implemented with microprocessor. The proposed control system has been simulated using Matlab software, and the system is tested at a different operating condition such as low speed and high speed.

Electric motors that convert electrical energy into motion are one of the basic components of automation systems. In these systems, either linear or circular motion is needed. Linear motion can be obtained either from motors that generate circular motion with the help of ancillary equipment or directly by the means of a linear motor. Obtaining linear motion from motors that produce rotary motion leads to additional costs and reduced efficiency. Linear motors, on the other hand, eliminate the need for conversion mechanisms. Despite this advantage, linear motors have some disadvantages, such as length limitation and low force/current ratio. In this study, a novel Cylindrical Direct Current Linear Motor (CDCLM) with high force/current ratio and no length limitation (long stroke) has been developed. Analyses of the developed motor has been performed with an analytical method. In addition, detailed numerical analyses have been carried out in an Ansys-Maxwell environment. A prototype of the designed DC linear motor has been implemented in a laboratory environment and experimental analyses have been carried out. The results of analytical, numerical and experimental analyses have been compared.

The objective of this article is to make a comparison in a computational environment between an alternating current motor and a direct current motor is made for dynamic variations in the propulsion of an artisanal fishing boat. Initially, the boat was simulated in the Maxsurf software to obtain the dynamic behaviors for pitching, rolling, yawing, and heave motions with wind and wave perturbations for a Pierson Moskowitz spectrum. Subsequently, the motors are selected and in Matlab/Simulink software and a torque behavior required by the vessel to act on the resistance presented in each dynamic motion is proposed. This allows for analyzing the required mechanical and electrical conditions, using the curves obtained in the simulation. Finally, it is concluded that taking into account the criteria of torque, power, speed, and current, the results obtained show that the DC motor is more efficient than the three-phase AC motor for artisanal fishing vessel applications. In addition, the two motors require greater effort to overcome the disturbance related to the rolling motion in the steady-state, while in the transient state the DC motor requires a higher starting torque and the AC motor presents oscillations, which are undesirable disturbances because they produce instability in the electrical system. Additionally, it is important to take into account the energy source that feeds the motors, which can be alternating current or direct current.

The permanent magnet DC motors are used in various applications as heater, wiper and personal computer. A DC motor is any of a class of electrical machines that converts direct current electrical power into mechanical power. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic; to periodically change the direction of current flow in part of the motor. Most types produce rotary motion; a linear motor directly produces force and motion in a straight line.

Switched reluctance motors are among the finest competitors to induction motors. It is a well-liked choice because of its durability, brevity, straightforward design, and superior torque to mass ratio. This page talks about the C-dump converter's design. The C-Dump converter makes it possible for the phase winding to be rapidly demagnetized and magnetized, which prevents the motor from being used in the generating state. Currents in the stator winding of a switching reluctance motor have a direct impact on the torque generated. A large negative voltage must be offered in order to quickly stop the current while it is working in the demagnetizing phase. This paper analyzes the C-dump converter's design. The C-Dump converter makes it possible for the phase winding to be rapidly demagnetized and magnetized, which prevents the motor from being used in the generating state. Switched reluctance motors demonstrate a variety of converter topologies for adjusting speed, power, and operation. Additionally, it frequently makes use of the energy that has accumulated in the phase winding and can be returned to the source. Some modified C-Dump converter topologies can utilize this stored energy to bypass the motor's next phase winding.

<p><span>Direct current (DC) motors are widely used in many applications especially those require a speed control, direction and closed-loop control system. In electric vehicle drive system, DC motor is commonly used for the propulsion of low power (<250 W) electric bicycle (e-bike) because it can operate directly from rechargeable batteries with a smart controller. In driving an e-bike in a closed loop control system, it is important to identify and estimate the dynamic of electrical and mechanical parameters. In this paper, the parameters such as armature resistance, armature inductance, back emf constant, torque constant, moment of inertia and viscous friction coefficient are ideally identified using dynamic responses experiments and tests focusing on no load motor and transient input tests. The motor is then modeled in MATLAB/Simulink using the identified motor parameters and its open loop speed and current responses are studied.</span></p>

DC motors are one of the most popular motors used in the industrial world. In operation, DC motors use a direct current (DC) source. In its application, the BLDC motor is combined with a method to make it easier to control the BLDC motor to match what is desired, one example is the Proportional Integral Derivative (PID) method, which is a control consisting of a standard configuration of Kp, Ki, and Kd whose values are determined in order to get the desired result or speed, namely speed with good stability with a small error rate and overshoot. The control system for the BLDC stepper motor nema 17 on the conveyor uses the STM32 Nucleo F030R8 module as a microcontroller and the HC-05 bluetooth module as a remote control interface on the conveyor motor. To send commands from the microcontroller to the motor, a driver is needed which is used as a data receiver and control setting from the microcontroller, namely the L298N motor driver. The monitoring system on the miniature conveyor uses an LM393 speed sensor as a stepper motor rotation speed reader and an INA219 sensor as a current and voltage reader. Sensor readings will be processed on the microcontroller and the results will be displayed on the 1.3-inch LCD screen that has been installed. In this study, it is still in prototype form, so the miniature conveyor cannot receive too heavy a load. The load is adjusted to the torque capacity of the BLDC stepper motor used, which is 0.36 N.m. In other words, the maximum miniature conveyor receives a load with a stable speed of less than or equal to 2 kg, because the load on the conveyor belt will affect the speed of the BLDC motor. With this research, it is hoped that it can be a lesson about control and monitoring systems on BLDC motors. The maximum Bluetooth range is 9 meters.

Electrical machines based on permanent magnet material excitations have been applied in many sectors since they are distinguished by their high torque-to-size ratio and offer high efficiency. Brushless permanent magnetic direct current (BLPMDC) motors are one type of these machines. They are preferable over conventional DC motors. one of the main challengings of the BLPMDC motor drives is the inherited feature of nonlinearity. Therefore, a conventional PID controller would not be an efficient choice for the speed control of such motors. The object of this paper is to design an efficient speed control for the BLPMDC motor. The proposed controller is based on the Fuzzy logic technique. MATLAB/ Simulink has been employed to design and test the drive system. Simulations were carried out for three cases, the first without a controller, the other using conventional control, and the third using expert systems. The results proved the possibility of improving the engine's working performance using the control systems. They also proved that the adoption of expert systems is better than the traditional nonlinear systems. The simulation response shows that the Rise Time(tr) at PID equals 66.306ms, while it equals 19.530ms for the Fuzzy logic controller. Moreover, Overshoot for PID and Fuzzy logic controller are 6.989% and 1.531%, respectively. On the other hand, undershoot is equal to 1.788% and 11.924% for PID and Fuzzy logic controller, respectively.

In using a 3 phase induction motor there are initial problems. Namely the surge in starting. In most motors induction mainly motors induction three- phase, current starting can reach four to seven times of great current nominal. Horse Power are large, allowing to happen surge currents starting the more substantial and is not be allowed, because it can disrupt the network and can damage the motor it 's own. For this reason, a starting method is needed which can reduce a very large starting current surge. There are several types of starting methods for electric motors. Among them, namely, DOL (direct on line), star-delta, auto transformers, and soft starting. The method that will be used in this research is the starting star-delta method. Star-delta starting is a system starting with running the motor with the configuration of star up first and then converted into a configuration delta for minimizing surge currents. Changes configuration is usually done by using a timer, when the timer has been reached setting the configuration will change. Applying Smartphone via Bluetooth and Arduino Uno R3 to operate a motor Starting way delta by way of sending the instruction in the form of data with a controller that is connected to the motor that. With this method motor operation is easier and safer.

The article is devoted to the so-called "war of currents", which unfolded in the United States in the late 19th-early 20th century. The winner of this "war" was a talented Serbian inventor Nikola Tesla. He professed the ideas of alternating current. He was opposed by the famous American businessman and scientist T. Edison. Enterprises of the latter produced machines running on direct current. It made a big profit. After a number of conflicts, Tesla, who worked for Edison, left his company and organized a business of his own jointly with an industrialist D. Westinghouse. Tesla's ideas and projects won a landslide victory. The development of direct current systems ended in the late 1920s, despite the efforts of T. Edison. N. Tesla was at the origins of alternating current systems, the appearance of electric motors, robotics, wireless charging devices and much more. Today, the ideas of the great Serbian inventor, even the most fantastic ones, are experiencing a rebirth.

(1) Background: The purpose of this study was to evaluate the analysis of measurements of bioelectric signals obtained from electromyographic sensors. A system that controls the speed and direction of rotation of a brushless DC motor (BLDC) was developed; (2) Methods: The system was designed and constructed for the acquisition and processing of differential muscle signals. Basic information for the development of the EMG signal processing system was also provided. A controller system implementing the algorithm necessary to control the speed and direction of rotation of the drive rotor was proposed; (3) Results: Using two muscle groups (biceps brachii and triceps), it was possible to control the direction and speed of rotation of the drive unit. The control system changed the rotational speed of the brushless motor with a delay of about 0.5 s in relation to the registered EMG signal amplitude change; (4) Conclusions: The prepared system meets all the design assumptions. In addition, it is scalable and allows users to adjust the signal level. Our designed system can be implemented for rehabilitation, and in exoskeletons or prostheses.

This study has aimed at establishing and analyzing the causes that produce oscillations of electromagnetic torque developed by brushless direct current motor. The study opportunity is given by the progresses obtained in command and power electronics, which made this motor performant from technical and economic viewpoint. The specialty literature reveals that important torque oscillations occur in this motor in a complete rotation. That is why, this study and the simulations presented here emphasize that there are five classes of slots relatively to the torque magnitude developed and the fact that all the slots are active, that meaning that the average torque developed occurs in the rotation direction. The harmonic analysis reveals that the torque distortion, within the five classes of slots, is variable between 51.03% and 97.63%. The torques computed for the slots classes are between the minimum limit of 0.029 Nm and the maximum one of 0.077 Nm. The low speed torque oscillations can be reduced with a high inertia moment, a speed reaction loop and a performant control system. The importance of the research theme is justified by what we have presented before and is a subject of major interest for engineering.

In this paper, a solution for the automatic control of the driving mechanisms that load/unload billets in/from a rotary hearth furnace is proposed. This problem is approached because in the actual stage the control of the loading/unloading machines is made manually. The treated solution is based on using, for each machine, a direct-current motor (d.c. motor) supplied through a direct-current converter (d.c. converter) for the forward-backward moving of the two machines to/from the furnace. In this context, the tuning of the controller implemented in the converter is made in order to assure the imposed speed of the motors and implicitly of the machines, respectively an appropriate speed evolution of the motors in the period of their acceleration and deceleration to assure the machines correct positioning.

Since permanent magnet direct current (DC) motors are mainly used in various industrial automation applications, the demand for electric motors is increasing rapidly. However, in the mass production of electric motors, often, only random inspections are used to check the specifications and performance of electric motors. For manufacturing or engineering application staff to have a more thorough understanding of the characteristics of the motor, it is necessary to conduct a full or quick inspection during the production process to ensure the quality of the electric motor. Based on this, this literature review reveals several methods and algorithms often used to estimate DC motor parameters, given the importance of knowing the parameters of the DC motor and the lack of research on estimating the parameters of the DC motor.

In this paper, the Nonlinear Model Predictive Control (NMPC) technique is proposed for the control of BrushLess Direct Current (BLDC) motors to address the problem of over-excitation, specifically in Electric Vehicle (EV) applications. This over-excitation increases the overall energy consumption of the machine and eventually reduces the vehicle’s driving range. The developed NMPC incorporates a nonlinear model of the BLDC motor with EV load and obtains the optimal current through the optimal voltage applied to the machine to regulate the motor torque. The proposed NMPC is compared with three conventional control techniques, the Field-Oriented Control (FOC), the Direct Torque Control (DTC), and the hybrid (the combination of DTC and FOC) control. It is observed from the simulation results that the proposed NMPC controller is more energy efficient while maintaining performance. This paper also discusses the selection of the motor based on the specified vehicle requirements. This has been done by matching the vehicle speed-torque characteristic curve with the motor’s one.

A control strategy of permanent magnet synchronous motors (PMSMs), which is different from the traditional vector control (VC) and direct torque control (DTC), is proposed. Firstly, the circular rotating magnetic field is analyzed on the simplified model and discredited into stepping magnetic field. The stepping magnetomotive force will drive the rotor to run as the stepping motor. Secondly, the stator current orientation is used to build the control model instead of rotor flux orientation. Then, the discrete current control strategy is set and adopted in positioning control. Three methods of the strategy are simulated in computer and tested on the experiment platform of PMSM. The control precision is also verified through the experiment.
