对于高速永磁同步电机，其磁场更为复杂，需要考虑旋转磁化和谐波。此外，高频、温度和压应力对电机铁损耗有相互作用。为了得到准确的HSPMSM铁损计算模型，本文提出了考虑这些物理因素的不同铁损模型，并给出了考虑多物理场因素相互作用的铁损模型。采用有限元法分析了高温永磁同步电机的磁场、温度场和应力场。然后，利用所提出的模型计算了硅钢片和原型的铁损。铁损模型考虑了多物理场因素的相互作用，并通过样机的实验测试验证了该模型的准确性。
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.
