For the high-speed permanent magnet synchronous motors (HSPMSMs), their magnetic fields are more complicated with the rotating magnetization and harmonics considered. Furthermore, there are interaction effects on motor iron loss from high frequency, temperature, and compressive stress. In order to obtain the accurate HSPMSM iron loss calculation model, different iron loss models are proposed, in this article, considering these physical factors, and the iron loss model considering the interaction effect of the multiphysics factors is given. The magnetic field, temperature field, and stress field are analyzed for HSPMSM by finite-element method (FEM). Then, the proposed models are employed to calculate the iron loss of the silicon steel sheet and the prototype. The accuracy of the proposed iron loss model, which can consider the interaction effect of the multiphysics factors, is verified by the experimental test measurements on the prototype.

考虑多物理场因素的高速永磁同步电机铁损计算方法


对于高速永磁同步电机（HSPMSM），考虑到旋转磁化和谐波，其磁场更加复杂。此外，高频、温度和压应力也会对电机铁损产生交互影响。为了获得准确的HSPMSM铁损计算模型，提出了不同的铁损模型，本文考虑这些物理因素，给出了考虑多物理因素相互作用影响的铁损模型。采用有限元法（FEM）对HSPMSM 的磁场、温度场和应力场进行了分析。然后，采用所提出的模型计算硅钢片和原型的铁损。通过样机上的实验测试测量验证了所提出的铁损模型的准确性，该模型考虑了多物理场因素的相互作用。
