Analysis of Fractional-slot Permanent Magnet Synchronous Machines Used for Hybrid Vehicles

This work presents an investigation on electromagnetic torque and electromagnetic force computations in the air gap of a V-shape permanent magnet synchronous motor (SMPM). The requirements for the fractional-slot stator winding (FSW) of the considered motor are presented. The conducted analysis has been accomplished through use of the application of finite element method. The suggested approach was used for synchronous motor with integral-slot stator winding (ISW) and the obtained results are compared.
