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.
