Design of a 5-Phase IPM Machine for Electric Vehicles

This paper presents the design of a 5-phase interior permanent magnet (IPM) machine for electric vehicle (EV) applications. The Nissan Leaf IPM machine is chosen as the benchmark system against which two designs are developed, 3- and 5-phase machines. The developed machines utilize the same rotor topology as the benchmark machine and adopt a 60-slot stator configuration to facilitate a short-pitch fractional-slot winding scheme. However, the …
