Abstract

This paper presents motor characteristics and radial magnetic force (RMF) of interior permanent magnet synchronous motors (IPMSM) according to pole/slot combinations. Three IPMSM of 15, 18, 24 slots with 16 poles are selected; 16 poles 15 slots and 18 slots provide high winding factor and 16 poles 24 slots is a general pole-slot combination. Using finite element analysis (FEA) and equivalent circuit analysis, output characteristics and motor parameters such as back electro-motive force (bemf), inductance, etc. are compared, and RMF in air gap causing noise and vibration is investigated. It is expected that presented study results help with appropriate choice of pole and slot number of IPMSM.
内嵌式永磁同步电机按极槽组合的特性及径向磁力
本文介绍了内嵌式永磁同步电动机(IPMSM)按极槽组合的电机特性和径向磁力。选择15、18、24槽16极3种IPMSM;16极15槽和18槽提供高缠绕系数,16极24槽是一般的极槽组合。采用有限元分析(FEA)和等效电路分析方法,比较了电机输出特性和反电动势(bemf)、电感等电机参数,研究了气隙内反电动势对噪声和振动的影响。期望本文的研究结果能对IPMSM的杆数和槽数的合理选择有所帮助。
