摘要：

This paper describes a design procedure that reduces the cogging torque of BLDC motor. This paper proposes that a predefined slot shape on the pole surface reduces the cogging torque. Used are the standard finite elements for field calculation, Maxwell stress tensor for torque, and evolution strategy for optimal design process to determine the slot size. Verified experiment shows that the proposed algorithm reduces the level of mechanical vibration and noise substantially.
