Abstract

In order to solve the problem of motor performance degradation caused by torque ripple and large cogging torque of in-wheel permanent magnet synchronous motor for electric vehicles, Taguchi is used to optimize the magnetic pole of built-in Permanent magnet synchronous motor, and the orthogonal optimization matrix of magnetic pole parameters is established. Through the parameter optimization matrix, the workload of pole optimization is reduced and the optimization speed is improved. The optimization results show that the orthogonal matrix optimization can not only improve the output torque of permanent magnet synchronous motor, but also further control its torque ripple and cogging. The orthogonal matrix optimization method used in this paper for V-I type built-in permanent magnet synchronous motor has a certain positive significance, and provides a certain reference value for the subsequent motor performance optimization.
基于田口方法的电动汽车轮内电机多目标优化设计
为解决电动汽车轮内永磁同步电机转矩纹波和大齿槽转矩导致电机性能下降的问题,采用田口方法对内置永磁同步电机磁极进行优化,建立了磁极参数正交优化矩阵。通过参数优化矩阵,减少了磁极优化的工作量,提高了优化速度。优化结果表明,正交矩阵优化不仅能提高永磁同步电机的输出转矩,还能进一步控制其转矩纹波和齿槽。本文针对 V-I 型内置永磁同步电机所采用的正交矩阵优化方法具有一定的积极意义,为后续电机性能优化提供了一定的参考价值。
