This paper presents a detailed calculation of the characteristics of five different topologies of permanent magnet (PM) machines for high performance traction including hybrid electric vehicles using the Finite Element Analysis (FEA) method. These machines include V-shape single layer interior PM, W-shape single-layer interior PM, Segment interior PM and Surface PM on the rotor with distributed winding on the stator. The performance characteristics include the back-EMF voltage and its harmonics, magnet mass, iron loss and ripple torque. In addition, a 7.5 kW IPM prototype was tested in order to verify the finite-element analysis results. The aim of this paper is to provide a reference for machine designers who are interested in IPM machine selection for high performance traction applications.
