| Summary: | Outer-rotor PM synchronous motor (OR-PMSM) with PM flux has shown to generate high torque and power densities. However, the round rotor used provides high iron loss and weight that affect their speed. This paper, addresses the problem using 24-stator and 14-segments flux switching machine (FSM) whose rotor is passive. Initially, performances of the designed motor such as cogging torque, harmonic distortion, average torque and power are analyzed. The initial design is optimized and the performances between initial and optimized OR-PMFSM designs are compared. The result shows OR-PMFSM has provided low cogging torque and low odd harmonic distortion to operate safely. The torque has increased to 48.81% from initial to optimize design of 240.5Nm and 469.8Nm. A comparative analysis of other motors for high torque such as OR-PMSM, OR-HEFSM and OR-FEFSM are presented. The proposed motor is capable to perform in high torque and high power conditions for automotive applications.
