Optimal Design of Rotor Pole of BLDC Motor Using Evolution Strategy

진화전략을 이용한 BLDC 전동기 회전자 자극의 최적설계

This paper presents the optimal design of a brushless DC motor(BLDC) keeping the average torque and cogging torque of the initial model while minimizing the volume of magnet pole by FEM and evolution strategy. Experimental tests are performed by the finite element method(FEM), and the random based evolution strategy is applied for the shape optimization. The optimal result shows a largely reduced volume of magnet pole.
