摘要推导了一种新型表面式无金属护套永磁同步电机永磁体涡流损耗解析模型,该模型同时考虑涡流反作用、开槽引起的磁导谐波和涡流分布不均匀三种因素,可以计算任意定子电流波形的表面式无金属护套永磁同步电机的永磁体涡流损耗,并能分析任意次数时空谐波产生的永磁体涡流损耗。采用所推导的解析模型研究影响永磁体涡流损耗的因素,包括调制比、载波比和气隙长度。调制比和载波比的增加减小了电流时间谐波幅值二次方和,因此降低了永磁体涡流损耗;气隙长度的增加,由于削弱了谐波电枢反应而降低了永磁体涡流损耗。通过对电机的实验分析和有限元仿真,验证了解析计算的正确性和规律的适用性。

Abstract：This paper deduces a novel analytical model of permanent magnet (PM) eddy current loss for surface mounted permanent magnet synchronous motor (PMSM) without metal shell, accounting for eddy current reaction, permeance harmonics due to slot and the unevenness of eddy current. This model can calculate eddy current loss with any stator current waveform in surface mounted PMSM without metal shell and can analyze PM eddy current loss caused by any time and spatial harmonics. By using this analytical model, the factors that affect PM eddy current loss are studied, including modulation index, frequency-carrier ratio and air gap length. With increasing the modulation index and frequency-carrier ratio, the sum of squared current time harmonics magnitudes decreases, and accordingly the PM eddy current loss decreases. The increase of air gap length wakens the harmonics armature reaction which decreases the PM eddy current loss. The calculated results and analysis are verified by tests and finite element method (FEM).
