Abstract

Abstract

In order to study operating performance of six-phase induction motor under control of trapezoidal wave phase current, six-phase trapezoidal wave phase current was decomposed into fundamental current and a series of harmonic current by Fourier decomposition, and then different harmonic magnetic produced by each subharmonic current was calculated. Finite element analysis results show that the six-phase induction motor eliminates the most obvious torque ripple in general motor generated by the fifth and seventh harmonic current.
