Reduction of the spatial harmonics of back electromotive force(EMF) is a useful way to reduce thrust ripple of permanent magnet linear synchronous motor (PMLSM). In this study, a method of v-skewing in the coils is proposed to reduce the harmonics to suppress thrust ripple in the PMLSM. The thrust and the harmonic are generated in a double-sided PMLSM model. The 3-D finite element method (FEM) is...
