A Novel Axial Flux Reversal Permanent Magnet Machine for Unmanned Electrical Vehicles

Due to the advantages of short axial length, small size and high power/torque density, the axial flux permanent magnet machine is considered to be a suitable option for the unmanned electrical vehicle application. In this paper, a novel axial flux reversal permanent magnet (AFRPM) machine with better performance is proposed and researched. Firstly, the topology of the machine is analyzed. Secondly, the power-size equation is deduced and the design scheme is presented. Finally, the electromagnetic performance is investigated. The results indicate that the AFRPM machine exhibits high power/torque density, outstanding material utilization and prominent torque capability.
