Abstract:
This study aims to design, develop, and evaluate the traction performance of an electric all-wheel-drive (AWD) tractor based on the power transmission and electric systems. The power transmission system includes the electric motor, helical gear reducer, planetary gear reducer, and tires. The electric system consists of a battery pack and charging system. An engine-generator and charger are installed to supply electric energy in emergency situations. The load measurement system consists of analog (current) and digital (battery voltage and rotational speed of the electric motor) components using a controller area network (CAN) bus. A traction test of the electric AWD tractor was performed towing a test vehicle. The output torques of the tractor motors during the traction test were calculated using the current and torque curves provided by the motor manufacturer. The agricultural work performance is verified by comparing the torque and rpm (T–N) curve of the motor with the reduction ratio applied. The traction is calculated using torque and specifications of the wheel, and traction performance is evaluated using tractive efficiency (TE) and dynamic ratio (DR). The results suggest a direction for the improvement of the electric drive system in agricultural research by comparison with the conventional tractor through the analysis of the agricultural performance and traction performance of the electric AWD tractor.

Abstract:
The issues of development of traction drives of locomotives are considered. It was found that with the existing limitations of the traction force and the speed of continuous operation, asynchronous traction motors do not have clear advantages over collector motors. The possibility of creating collector motors for electric locomotives with a power equal to the used asynchronous ones has been proved, new technical solutions have been proposed for units that ensure the reliability of the latter when using high-torque motors (elastic gearwheel with chevron teeth, two-layer rubber-metal hinge, rubber-cord clutch options), as an optimal solution for the drive with collector motors, it is proposed to use a drive with a support frame motor and an axial gearbox. The directions of research necessary for the practical implementation of drives with a high-torque traction motor are determined, it is proposed to conduct research on the feasibility of creating diesel locomotives with bogies, unified with electric locomotives. The proposed solutions received two patents for inventions, eight patents for utility models, two patent applications were filed.

Abstract:
The article examines curves controlling asynchronous traction motors increasingly used in locomotive electric drives the main task of which is to create a tractive effort‐speed curve of an ideal locomotive Fk = f(v), including a hyperbolic area the curve of which will create conditions showing that energy created by the diesel engine of diesel locomotives (electric locomotives and in case of electric trains, electricity taken from the contact network) over the entire range of locomotive speed is turned into efficient work. Mechanical power on wheel sets is constant Pk = Fkv = const, the power of the diesel engine is fully used over the entire range of locomotive speed. Tractive effort‐speed curve Fk(v) shows the dependency of locomotive traction power Fk on movement speed v. The article presents theoretical and practical aspects relevant to creating the structure of locomotive electric drive and selecting optimal control that is especially relevant to creating the structure of locomotive electric drive using ATM (asynchronous traction motor) that gains special popularity in traction rolling stock replacing DC traction motors having low reliability. __e frequency modes of asynchronous motor speed regulation are examined. To control ATM, the authors suggest the method of vector control presenting the structural schemes of a locomotive with ATM and control algorithm.

Abstract:
The analysis of operating conditions of traction drives of electric locomotives with asynchronous traction motors has been carried out. It was found that during operation in the output converter of an asynchronous motor, defects may occur, which leads to asymmetric modes of its operation. Models of a traction drive of an electric locomotive with asynchronous motors with scalar and vector control of the output converter are proposed, taking into account asymmetric operating modes. As a result of the simulation, the starting characteristics of the traction drive were obtained for various control methods both in normal and emergency modes of the drive. For the drive-in emergency mode, the following cases were investigated: the balance of the converter output voltages and the turn-to-turn circuit of 10% of phase A winding of the motor stator; imbalance of the output voltages of the inverter and an intact motor; imbalance of the output voltages of the converter and interturn short circuit of 10% of phase A winding of the motor stator. Comparison of the simulation results have shown that in emergency modes in the traction drive, the torque ripple on the motor shaft in the drive with vector control is 13% less, and in scalar control, the phase current unbalance coefficient is 22% less. The results of this work can be used to study the influence of the output converter control methods on the energy efficiency indicators of the traction drive of an AC electric locomotive.

Abstract:
The parameters of electromechanical transmission for the tractor of 0.6-0.9 traction class are selected based on the analysis of traction and hitching characteristics of the complete machine. The authors have made theoretical calculations of the operating characteristics of the prototype tractor with an internal combustion engine and the tractor layout with an electric drive, traction calculation of the prototype tractor and the tractor layout, and calculation of the characteristics of the electric drive and electric motors. For the calculations, a six-speed manual variable gearbox was selected. The initial data for performing the calculations were obtained from the results of tractor traction tests in the North Caucasian machine test station. Two profi le backgrounds of the support base were selected: a fi eld prepared for sowing (fallow) and stubble. As a result of research, it was established that a tractor-model designed on the basis of the self-propelled chassis of a pulling class 0.6 to. 0.9 with capacity up to 50 kW on the “Fiel d prepared for sowing” background reaches the greatest towing effi ciency (0.53) with the 15 kW electric motor and the greatest drawbar pull (5.78 kN) with the 18 kW electric motor. On the “Stubble” background, for 15, 18 and 22kW electric motors, the pulling effi ciency is 68%, but the tractor layout with the 22kW electric motor can develop the maximum drawbar pull of 11.35kN. The maximum pulling power of 16.7 kN is observed in the prototype tractor with an internal combustion engine. Therefore, the 15-kW electric motor can be the only most suitable substitute for a combustion engine by traction effi ciency.

Abstract:
The problem of search new design schemes of a traction mechanism for a locomotive with mass drive partial springing is under consideration. New design schemes are offered: a drive with a movable joint of a drive motor and an axial reducing gear and a drive with a disk motor with the separation of a stator and rotor. The authors offer to return to the development of supportframe drives with an axial reducing gear as it is simpler in manufacturing and assemblage on the basis of updated data of their operating modes. The authors also offer their own design of an integrated traction drive with a swivel of a motor and reducing gear which is simpler in manufacturing and assemblage as compared with the foreign analogues. The introduction of nonsynchronous traction electric motors having a smaller mass and higher reliability as compared with commutator motors resulted in new designs of a supportaxial drive by foreign manufacturers and their introduction in the market of domestic rolling-stock. This work shows an attempt to determine possibilities to eliminate dependence mentioned by means of the analysis of basic problems in the development of supportaxial drive design and new structural scheme searches.

Abstract:
One of the assumptions made during the modernization process of diesel shunting locomotives is the replacement of a diesel traction motor with a DC generator with an electric asynchronous traction motor. The article aimed to develop a method of selecting energy-efficient parameters of an asynchronous electric traction motor for diesel shunting locomotives, which will ensure that its operating energy efficiency will be as high as possible. The method was verified on the example of a locomotive series ChME3 (ЧMЭ3, ČME3, ČKD S200). It has been found that using a traction asynchronous electric drive on a ChME3 locomotive, its efficiency increases in comparison with DC electric motors by 3–5% under the long-term operation modes and by 7–10% during locomotive operation with traction at the adhesion limit. Using a new traction gearbox with a higher gear ratio expands the speed range in which the asynchronous traction drive operates with a high-efficiency factor. It is effective to use a traction asynchronous electric drive to modernize ChME3 diesel locomotives in case of their use under the modes requiring the implementation of maximum traction forces at low speeds. A further increase in the efficiency of the traction asynchronous electric drive is possible based on the optimal design of the wheel-motor unit and the asynchronous traction electric drive.

Abstract:
Induction motors are popularly used in various applications because of the proposed modest construction, substantiated process, and limited size of specific power. The traditional AC traction drives are experimentally analyzed. There is a high circulating current due to the high Common-Mode Voltage (CMV). The high Circulating Bearing Current (CBC) is a major problem in conventional two-level voltage source inverter fed parallel-connected sensor-based induction motors for traction applications. A sensorless method is well known for shrinking costs and enhancing the reliability of an induction motor drive. The modified artificial neural network-based model reference adaptive system is designed to realize speed estimation methods for the sensorless drive. Four dissimilar multilevel inverter network topologies are being implemented to reduce CBC in the proposed sensorless traction motor drives. The multilevel inverter types are T-bridge, Neutral Point Clamped Inverter (NPC), cascaded H-bridge, and modified reduced switch topologies. The four methods are compared, and the best method has been identified in terms of 80% less CMV compared to the conventional one. The modified cascaded H-bridge inverter reduces the CBC of the proposed artificial neural network-based parallel connected induction motor; it is 50% compared to the conventional method. The CBC of the modified method is analyzed and associated with the traditional method. Finally, the parallel-connected induction motor traction drive hardware is implemented, and the performance is analyzed.

Abstract:
Energy demands are steadily increasing as the world's population continues to grow. Automobiles are primary transportation means in a large portion of the world. The combination of fuel consumption by automobiles along with the shrinking fossil fuel reserves makes the development of new more energy efficient technologies crucial. Electric vehicle technologies have been studied and are still being studied today as a means of improving fuel efficiency. To that end, this work studies the effect of switching frequency on the efficiency of a hybrid electric vehicle traction drive, which contains both an internal combustion engine as well as electric motor. Therefore improving the efficiency of the electric motor and its drive will help improve the viability of alternative vehicle technologies. Automobiles spend the majority of their operational time in the lower speed, lower torque region. This work focuses on efficiency improvements in that region. To estimate the efficiency trend, the system is modeled and then tested both electrically and thermally. The efficiency is shown to increase at lower switching frequencies. The experimental results show that there are some exceptions, but the basic trend is the same.

This thesis presents a detailed comparison of the torque-speed characteristics of three permanent magnet synchronous machine designs based on how the magnets are mounted. The machines investigated are an interior permanent magnet machine, an interior-rotor surface-mounted machine and an exterior-rotor surface-mounted machine. They are designed for traction drives in hybrid electric vehicles. Two sets of comparisons based on the same machine volume and starting torque are performed. Important issues, such as machine mass and cost, cogging torque, and flux-weakening capability are addressed. Computer simulations were performed to estimate their performances and the results are presented. Design guidelines and tradeoffs of their performances are extracted from the simulation results. Relative strengths and limitations of different PM machine types are highlighted.

Abstract:
In a world with a growing population there is a trend toward higher and higher energy usage. Because of the cost involved in producing extra energy, there is a need for more efficient usage of the energy that is already available. The issue of efficiency rings home especially clear with electric motors. Although induction motors are used in many different applications, the motors used in electric vehicles must be able to generate a large starting torque as well as operate over a wide speed range. This work analyzes the restrictions placed on the motor and inverter drive system. It also looks at the best method for controlling the drive in order to achieve the highest efficiency out of the drive. While other works have shown methods of achieve high efficiency out of the motor, it is the assertion of this work that the efficiency of the total drive is more important. It is to that end that this work analyzes the performance of an induction motor under low torque and speed where a traction drive utilizes the most energy.

Thesis for the degree of Doctor of Engineering in specialty 05.22.09 "Electric transport " - National Technical University "Kharkiv Polytechnic Institute" MES of Ukraine, Kharkov, 2018. The thesis is devoted to the creation of scientific foundations for the selection of optimal parameters and operating modes for cooling systems for asynchronous traction motors of electric transport. An algorithm for solving the Hamilton-Jacobi-Bellman equation for the problem of the motion of an electric stock on a section of a track with a given profile and a traffic schedule is developed. That makes it possible to create an expert control system for motion. Features of this algorithm is the use of penalty functions to describe the restrictions imposed by the traffic schedule: the train reaches the destination point for a given driving time, the speed limit on the sections of the track, and the absence of train idle time during the movement. A single approach to penalty functions is also applied to introduce constraints on the adhesion. This approach allows to reduce significantly the costs of the estimated time and to simplify the procedures for calculating energy costs. A mathematical model is created to determine the efficiency of the traction drive. The model includes the determination of the main losses in an asynchronous traction motor, taking into account the saturation of the magnetic system, which is determined by the results of solving a recurrent nonlinear equation. Also, the model takes into account losses from higher harmonic stresses in copper and steel, mechanical and additional losses. The developed model takes into account static and dynamic losses in IGBT transistors and diodes of a semiconductor converter. A method for optimizing the parameters and operating modes of cooling systems for asynchronous traction motors of the electric stock is developed. It consists of the following main stages: determination of the optimum mode of the traction drive operation on the basis of the proposed expression of its efficiency; determination of optimum modes of movement of the electric stock by the criterion of minimum costs; solution of the traction problem of motion on a section of the track with a specified traffic schedule and the track profile, as well as the determination of the dependence of the change in losses in the elements of asynchronous traction engines in time; choice of parameters and operation modes of cooling systems for asynchronous traction motors, which determine the efficiency of the cooling and ventilation system of the electric stock; solution of the problem of relative minimization of the cooling system for asynchronous traction motors with a modernized criterion of economic efficiency based on the Weil method on the generalized golden section and the problem of analyzing the ventilation and cooling system of traction motors, which is based on the mathematical model of thermal motor conditions by the generalized equivalent thermal scheme.

Thesis for the degree of Doctor of Engineering in specialty 05.22.09 "Electric transport " - National Technical University "Kharkiv Polytechnic Institute" MES of Ukraine, Kharkov, 2018. The thesis is devoted to the creation of scientific foundations for the selection of optimal parameters and operating modes for cooling systems for asynchronous traction motors of electric transport. An algorithm for solving the Hamilton-Jacobi-Bellman equation for the problem of the motion of an electric stock on a section of a track with a given profile and a traffic schedule is developed. That makes it possible to create an expert control system for motion. Features of this algorithm is the use of penalty functions to describe the restrictions imposed by the traffic schedule: the train reaches the destination point for a given driving time, the speed limit on the sections of the track, and the absence of train idle time during the movement. A single approach to penalty functions is also applied to introduce constraints on the adhesion. This approach allows to reduce significantly the costs of the estimated time and to simplify the procedures for calculating energy costs. A mathematical model is created to determine the efficiency of the traction drive. The model includes the determination of the main losses in an asynchronous traction motor, taking into account the saturation of the magnetic system, which is determined by the results of solving a recurrent nonlinear equation. Also, the model takes into account losses from higher harmonic stresses in copper and steel, mechanical and additional losses. The developed model takes into account static and dynamic losses in IGBT transistors and diodes of a semiconductor converter. A method for optimizing the parameters and operating modes of cooling systems for asynchronous traction motors of the electric stock is developed. It consists of the following main stages: determination of the optimum mode of the traction drive operation on the basis of the proposed expression of its efficiency; determination of optimum modes of movement of the electric stock by the criterion of minimum costs; solution of the traction problem of motion on a section of the track with a specified traffic schedule and the track profile, as well as the determination of the dependence of the change in losses in the elements of asynchronous traction engines in time; choice of parameters and operation modes of cooling systems for asynchronous traction motors, which determine the efficiency of the cooling and ventilation system of the electric stock; solution of the problem of relative minimization of the cooling system for asynchronous traction motors with a modernized criterion of economic efficiency based on the Weil method on the generalized golden section and the problem of analyzing the ventilation and cooling system of traction motors, which is based on the mathematical model of thermal motor conditions by the generalized equivalent thermal scheme.

Abstract:
Micro traction drive is a device to transmit driving force modified from angular ball bearing. The micro traction drive consists of an input/inner ring, an outer ring, a rolling element, a retainer/output shaft, and a casing. In addition, the micro traction drive of the tandem type that combined two bearings was developed to obtain a big reduction ratio. As a result, we are able to attain the reduction ratio 7.3. Traction oil on the market was sealed in the test piece for oil bath lubrication. Input shaft could be driven with a motor in ultra high speed. Power absorbing type test equipment was made the efficiency and temperature of micro traction drive operated at high speed were successfully measured. In the result of measurement, temperature rise are a few and it turns out a micro traction drive can be used by ultra high-speed.
