In-wheel outer rotor flux switching permanent magnet machine with fractional-slot concentrated windings for electrical vehicles

In this paper, a 15kW novel out rotor flux switching permanent magnet machine (OR-FSPM) with 48/56 stator/rotor configuration (OR-FSPM) is proposed for in-wheel electrical vehicle. The OR-FSPM machine with fractional-slot concentrated windings (FSCWs) has become good candidates for in-wheel motors due to their robust rotor structure, high torque and power capability. What is more, the out rotor configuration of the machine can provide the convenient for in-wheel direct drive. Comprehensive simulations based finite element analysis (FEA) are studied on the overall electromagnetic property of this machine, especially the output capability.
