研究了永磁体对永磁同步电机(PMSM)全系统效率的影响。设计了两种具有相同反电势和输出功率的铁氧体磁体和Nd-Fe-B永磁同步电机。首先，对这两种电机的参数进行了动态仿真。可以评估晶体管的电流波形和开关损耗。然后，根据得到的电流波形和一系列的数值方法，计算出这两种电机的铁耗。最后，比较开关损耗和铁耗之和，结果可以反映磁体对整个电机系统效率的影响。
This paper studies the influence of permanent magnet on the total system efficiency of permanent magnet synchronous motors (PMSM). Two PMSM with Nd-Fe-B and Ferrite magnets which have same Back-EMF and output power have been designed. First, the dynamic simulation is performed with these two motors' parameters. The current waveforms and switching losses of transistors can be evaluated. And then, by means of the obtained current waveforms and a series of numerical methods, the iron losses of these two motors will be calculated. Finally, comparing the sum of the switching losses and iron losses, the result can be used to reflect the influence of the magnet on the total motor system efficiency.
