N2 - This paper presents the design optimization process of traction motor for electric race car in order to balance the power-density and efficiency under a given typical race duty-cycle while maintaining the required torque-speed range. The investigated electric race car energy distribution over the race duty-cycle is modelled and representative points are identified. Design optimization is carried out based on these representative points by parametrized finite element motor model. The optimization results are evaluated by performance indexes such as active total mass, motor losses, torque ripple and discussed by multi-physics analysis of the optimal design choices. Finally, a 10-pole 12-slot spoke type permanent magnet motor is considered, both electromagnetic and thermal performance are evaluated to improve the motor efficiency and power density over motor torque-speed plane.
