Повний текст джерелаThis thesis presents a study of the effects of inter-bar currents on inductionmotor starting performance and stray-load losses. The work is focused on theperformance differences between aluminium and copper casted rotors.A method to predict the stator current when starting direct-on-line isdeveloped. This includes modelling of skin-effect, saturation of the leakageflux paths and additional iron losses. The results are verified by measurements.An analytical model accounting for inter-bar currents is derived, andthe dependency of the harmonic rotor currents on the inter-bar resistivity isinvestigated. It is found that the inter-bar currents can have considerableeffect on motor starting performance and stray-load losses, the amount beingstrongly dependent on the harmonic content of the primary MMF.Based on measurements of inter-bar resistivity, the starting performanceof an aluminium and a copper casted rotor is simulated. The results indicatea higher pull-out torque of the aluminium rotor than for the equivalent copperrotor. This is rather due to an increase of the fundamental starting torque ofthe aluminium rotor, than due to braking torques from the space harmonicsin the copper rotor. The results are verified by measurements. It is foundthat the difference between the pull-out torques is even larger than calculatedfrom the model. Thereby, it can be concluded that the inter-bar currents havea considerable effect on motor starting performance.At rated speed the braking torques are larger in the aluminium rotor thanin the copper rotor. This is seen as increased harmonic joule losses in the rotorcage. Simulations have shown, that these losses can be as large as 1% ofthe output power for the studied machine.

Abstract This paper presents the analysis of the characteristic equation of copper rotor three phase induction motors established by equivalent circuit. In addition, this paper also shows the influence of the materials and sizes of squirrel-cage rotor copper bars on motor performances. Even though the copper rotors are not currently widely-used, increasing the efficiency of motors has become a crucial issue. The copper rotors may gradually take place of aluminum rotors. Thus it is important to do research in the characteristics of copper rotors. Induction motors are popular not only in industries but also in daily life. It is environmental-friendly and power-saving to increasing the efficiency of induction motors. This paper discusses and analyzes the change of torque characteristics on a 200W/12pole copper rotor three phase induction motor with different the rotor materials and stator windings. Therefore, we may be able to know more about the influence of copper rotors on the torque characteristics of induction motors. Simulation software can also help to simulate and calculate the other characteristics of induction motors, such as current, power or power factors, etc. Besides, we also focus on factors for influencing efficiency. Next we do experiments to prove the analysis of equivalent circuit and simulation. For example, DC test, lock-rotor test, no-load test and increase-load test, and so on. These tests prove that equivalent circuit shows the data that affects efficiency. Moreover, with modifying the data for simulation software, we can know more information about data for influences and value of improving efficiency by modifying motors. Key words: three phase induction motor, squirrel-cage rotor copper bar, efficiency of three phase induction motor.

This thesis studies the design, analysis process, and vector control of an induction motor applied to an electric vehicle. Electric cars should have high power density and high efficiency. In order to achieve these requirements, we raise the stator winding slot rate and use the high-grade thin silicon of steel to reduce core loss. In addition, stator windings use short-pitch and double-layered windings of design to reduce the primary wire loss and high frequency harmonics. To increase conductivity and reduce the secondary wire loss, rotor winding is also used by copper rotor. This design is the electric vehicle of induction motor that contains a 3-phase 4-pole, continuous power output 35 kW, maximum power 105kW and efficiency higher than 94%. It explains that the motor design, electromagnetic field and equivalent circuit analysis points. Eventually, we conduct the characteristic Simulation and measuring. In the motor vector of control research, first of all, we understand the three-phase induction motor vector control of coordinate transformation theory, which contains PARK, CLACK conversion and PI control etc. Then we discussed for the amount of scalar, direct and indirect field-oriented control.Finally, using the MATLAB / SIMULINK conduct the Simulation and Analysis for motor open loop, closed-loop and Field-oriented speed control system, and we discussed for the dynamic response under different loading.

Recently, issues such as saving energy and reducing emissions have become more important. Developing electric vehicles (EV) can reduce gasoline consumption and emissions of carbon dioxide to resolve the problems of energy crisis and climate changes .Also, replacing the traditional material used of aluminum in induction motor with copper can improve its capability for EVs. And the control strategies of the high efficiency motor play an important role in the development of high performance EV power trains .Therefore, this study presents field oriented control (FOC) based on space vector pulse width modulation (SVPWM) for high efficiency copper rotor induction motor (CRIM).First, we used MATLAB Simulink to simulate FOC scheme that provide three-phase induction motor individual control of torque producing and flux producing component just like DC motor. Second, we embedded the control software in TMS320F28335 high performance digital signal processor (DSP) which produced by Texas Instrument and test the operation characteristic of FOC base on SVPWM for CRIM.

In this thesis, the effect of different rotor conductor materials for the motor characteristics is studied. During the experiment, two induction motors are drived to measurement, a induction motor are installed by aluminum rotor and the other one is by copper rotor, and an inverter is used to drive them to operate at various speeds to measure the motor phase current as well as the size of the input power, and the measured induction motor in the long-term operation under conditions of temperature changes, to observe the rotor conductor material for induction motor. A 2-pole, 370 W induction motor is choose, which installed by aluminum die-cast rotor and copper die-cast rotor induction motors respectively. By the experiment results, the average input power of die-cast copper rotor induction motor is 93.3 % to die-cast aluminum rotor induction motor, and the average phase current is 97.8 % to die-cast aluminum rotor induction motor. Finally, when motor operate one hour without cooling fan, the temperature of die-cast copper rotor induction motor is lower 0.7℃ than die-cast aluminum rotor induction motor.
