Comparison of Energy Conversion Characteristics between Permanent Magnet Synchronous Motor and Synchronous Reluctance Motor

针对燃料电池空压机的两种不同转子形式的高速电机,从能量转换的角度进行对比研究。运用Ansoft软件分别建立永磁同步电机和同步磁阻电机模型,提取电机各点的相关参数,计算得到各点坡印廷矢量值,绘制坡印廷矢量云图反映电机内部的能量流动和转换情况。通过对比两台电机的仿真计算结果,分析并研究了其能量转换特性。

This paper carries out studies aiming at the research on comparison of two kinds of high-speed motor with different forms of rotor, from the perspective of energy conversion. The model of the permanent magnet synchronous motor and the synchronous reluctance motor was established by using Ansoft. Through simulation, the parameters of each point of the motor are extracted and each point＇s Poynting vector values of are calculated. The Poynting vector map was plotted to reflect the energy flow and the conversion of the motor. By comparing the simulation results of two motors, the energy conversion characteristics of them are analyzed.
