The shape optimal design to improve efficiency of double winding 2-phase BLDC motor for Hairdryer

효율 개선을 위한 헤어 드라이기용 이중권선형 2상 BLDC 전동기의 형상 최적 설계

This paper proposes a structure optimal design of 2-phase BLDC motor. In order to improve the characteristics of the BLDC motor such as the efficiency, average torque, the Kriging method and genetic algorithm are utilized. In addition, the result of the optimal model were compared with the initial model and verified by 2D FEM.
