Özet

© 2016 IEEE.Rotor bar current of an induction machine (IM) designed by using the same stator outer diameter, stack length, air-gap length, output power and rated speed as the Toyota Prius 2010 interior permanent magnet machine is investigated. It is observed that in some cases the rotor bar current waveform can be non-sinusoidal even if the stator windings are fed with a sinusoidal source. The conditions for such non-sinusoidal rotor bar current to occur and the reasons behind this phenomenon are investigated by finite element method, with particular reference to the influence of slip and electric loading.
