Because the magnetic properties of an amorphous alloy (AA) obviously change with the change of temperature, a finite element simulation method for a motor, considering the effect of temperature, is proposed in this paper. In the early design stage of the high-speed permanent magnet synchronous motor (PMSM), the simulation of motor performance is mainly based on the magnetic performance test data at room temperature provided by the material's manufacturer. However, the influence of the temperature rise during the actual operation of the motor will lead to large errors between the simulation results and the measured results. Therefore, it is of great practical significance to measure the magnetic properties of the AA at different temperatures and use them for simulation purposes. In this paper, the magnetization characteristics and iron loss characteristics of the AA and silicon steel (ST100) used for comparison are measured at different temperatures, and the iron loss separation of the two materials at different temperatures is completed, and the hysteresis loss coefficient and eddy current loss coefficient at different temperatures are obtained. On this basis, the performance simulation of a motor model is carried out. The more accurate simulation method proposed in this paper can provide a reference for the design of AA motors in industry.
由于非晶合金（AA）的磁性能会随温度变化而明显改变，本文提出了一种考虑温度影响的电机有限元仿真方法。在高速永磁同步电机（PMSM）的早期设计阶段，电机性能仿真主要基于材料制造商提供的室温下的磁性能测试数据。然而，电机实际运行过程中的温度升高影响会导致仿真结果与实测结果之间存在较大误差。因此，测量不同温度下非晶合金的磁性能并将其用于仿真具有重要的实际意义。本文测量了非晶合金以及用于对比的硅钢（ST100）在不同温度下的磁化特性和铁损特性，完成了两种材料在不同温度下的铁损分离，并得到了不同温度下的磁滞损耗系数和涡流损耗系数。在此基础上，对电机模型进行了性能仿真。本文提出的更精确的仿真方法可为工业中非晶合金电机的设计提供参考。
