Abstract

Distributed windings have been extensively equipped in permanent magnet synchronous machine (PMSM) because of their inherent sinusoidal electromotive force (EMF) waveform. Recent work by the authors shows the differences of winding factors between non-overlapping windings and its distributed windings counterpart. The winding factors of non- overlapping concentrated windings eliminate only part of EMF waveform harmonics. Latter suggestion is that with careful design of slot width, the EMF waveform of non-overlapping windings can also be sinusoidal. Finite element analysis model and experiment results validate the analysis in this paper.
