In view of that detent force (DF) spatial harmonic has great influence on thrust ripple of permanent magnet synchronous linear motor (PMSLM), a harmonic suppression method is proposed. DF of the PMSLM model is calculated by finite element method (FEM) and its harmonic spectrum is achieved by Fourier...
