A novel axial flux induction motor is proposed as the driving machine for electric vehicle, the motor consists of two rotors and one yokeless stator. Benefit from this structure, grain-oriented silicon steel can be used to reduce the weight and improve efficiency. The present paper provides the basic topology of the motor, discussing the design method and analyzing the performance. A prototype is designed, considering the 3D finite element method is time-consuming and inefficient, analytical calculation method is deduced to calculate the performance of the prototype, the results agree with those obtained by finite element calculation, that verifies the effectiveness of this method.
