Electromagnetic Performance

This paper discusses the design of a fault-tolerant Permanent-Magnet Synchronous Machine (PMSM) for electric vehicles. The investigated machine is a five-phase in-wheel machine with 40 slots and 42 poles. The electromagnetic performance of double layer and single layer windings are compared based finite element analysis. The magnetic isolation abilities of the two winding types are also compared. Finally, a 12kW five-phase fault-tolerant machine which is able to meet the demand of electric drive system is designed and evaluated.
