Abstract

Abstract

By using the field-route coupling method, the causes and main components of the high frequency radial electromagnetic force characteristic frequency of permanent magnet synchronous motor were studied. The generation mechanism and harmonic characteristics of harmonic current were analyzed by analytical method, and verified by numerical simulation. The characteristic frequency distribution of high frequency radial electromagnetic force was analyzed by means of the magnetomotive force permeability method and Maxwell tensor method. The air gap magnetic field obtained by finite element calculation was decomposed in time and space, and the high frequency radial electromagnetic force generated by magnetic field interaction was calculated by Maxwell tensor method. The results show that the high frequency radial electromagnetic force of PMSM driven by frequency conversion is mainly generated by the interaction between the harmonic magnetic field and the stator fundamental magnetic field introduced by the harmonic current of the frequency converter, which has certain guiding significance for the research of PMSM.
