中文摘要

本文针对开关磁阻电机(SRM)因双凸极结构导致的噪声、振动和声振粗糙度(NVH)问题,提出了一种定子结构改进方案。通过引入定子极桥设计,有效提升了结构的刚度质量比。研究以一款24槽16极的车用SRM为对象,验证了该方法在宽转速范围内抑制振动与噪声的有效性。

English Abstract

Noise, vibration, and harshness (NVH) issue in switched reluctance machines (SRMs), originating from their doubly salient structure and unique principle of operation, is addressed in this work by proposing a structural design modification in the stator, which increases stiffness to mass ratio of the structure. A 24-slot 16-pole (24s/16p) SRM designed with the aim of automotive application is studi...

该研究聚焦于开关磁阻电机(SRM)的NVH优化,虽然阳光电源目前的核心业务集中在光伏逆变器、储能PCS及风电变流器,但该技术在电机结构设计与振动抑制方面的思路,对阳光电源的电动汽车充电桩功率模块散热风扇电机选型,以及未来可能涉及的电机驱动类辅助系统具有参考价值。此外,文中提到的有限元仿真与结构优化方法,可借鉴用于提升阳光电源大功率储能PCS中电感与变压器等磁性元件的电磁振动抑制及可靠性设计,以优化产品在全功率运行下的声学表现。
