Stator FEM modeling of permanent magnet synchronous motor for electric vehicle driving based on structural vibration analysis

Abstract

Stator of a permanent magnet synchronous motor (PMSM) for electric vehicle driving is focused on as the research object. Six kinds of finite element models for winding are built, and compared with test results to elect the model consistent with the actual stator winding. This model established contributes to the reference of motor stator vibration characteristics analysis model. On the basis of this model, analyze the impact of winding, stator case and end cap on vibration character, and its reasons. © 2010 IEEE.
