摘要

This article concerns the geometric optimization of permanent magnets motor structures using Finite Element software. The study presented in this paper concerns the back electromotive force shape optimization for the reduction of the motor ripple torque. This study is based on two steps: firstly, the pre-dimensioning of the motor structures using the analytical method and, secondly, optimization of the geometry of the studied motor structures through the finite element method since the shape of the back electromotive forces strongly depend on the geometry of the motor structure such as the width of the magnets. Simulation results based on a parameterized finite element model show the performance of the study and its influence on the motor performance such as ripple torque.
