Dual-Rotor Permanent Magnet Motor for Electric Superbike

The demand on high-performance electrical machines has significantly increased for aerospace and transportation industries in recent years. A racing electric motorbike is a suitable platform to validate and prove new concepts and machine topologies before implementing them for passenger transportation applications. This paper describes the design and development of a high power density dual-rotor permanent magnet machine for an electric superbike. A holistic multi-domain design tool based on genetic algorithm-optimization is used for identifying the optimal slot-pole configuration and assist with the system architecture studies. The selected machine is then further refined and analyzed in conjunction with the power-electronic converter used for the application in hand.
