项目摘要

In this research, one of the purpose of our works is to analyze and find out the effects of crosspath resistance between rotor bars, skew factor and skin effects on the rotor slot design of inverter-fed high speed cage induction motor driving for wide speed range of electric vehcles. The performance of the induction motor drives for various values of crosspath resistance, and skew factor with the trapezoidal rotor bar have been discussed on the basis of theoretical and simulationresults of a three phase induction motor taking into account the skin effect of the rotor and the space harmonics. It has been obtained that the equivalent rotor resistance and leakage reactance change with crosspath resistance, the space harmonics, and the skew factor for various values of the fundamental supply frequency. And finally, we discussed the rotor slot-shape of the trapezoidal rotor slot for good efficiency and torque performance of the inverter-fed high speed cage induction motor for wide speed range of electric vehcles.The other purpose of this research is to suggest the high efficiency rotor flux control of the speed sensor less direct-field-oriented controlled induction motor operating at high efficiency for wide speed range of electric vehcles. The proposed system was achieved by using an adaptive rotor flux observer. This was shown by experimental and simulation results. The proposed system was far superior to one with a constant rated rotor flux with regard to efficiency in the steady state, and it's motor speed response showed no degradation in the transient state.Finally, It has been made clear that the stator voltage offset influences the low speed characteristics of the sensorless direct-field- oriented induction motor drives significantly. Furthermore, a method of compensating the stator voltage offset has been proposed. The validity of the proposed method has been verified by the simulation and experiment.
