Abstract

The influence of skew on the rotor bar current waveform and performance of an induction machine (IM) designed by using the same stator outer diameter, stack length, output power, and rated speed as the Toyota Prius 2010 interior permanent magnet machine have been investigated in depth. It reveals that skew has a substantial effect on the, rotor bar current waveform, bar resistance, average torque, torque ripple, slot leakage flux, power losses, and efficiency. The conditions when the non-sinusoidal rotor bar current waveform occurs and the reasons behind this phenomenon are investigated by finite element analysis.
