Optimal Design of Rotor Pole of BLDC Motor Using Taguchi Method and FEM

Taguchi 방법과 FEM을 이용한 BLDC 전동기 회전자 자극의 최적설계

This paper presents the optimal design of BLDC motor keeping the average torque and cogging toruqe of the initial model while minimizing the volume of magnet pole by FEM and Taguchi method. Experimental tests are performed by Finite element method, and the second order polynomial equations are obtained from FEM results due to design parameter variation referred to orthogonal arrays by Taguchi. The presented optimization shows a big reduction of computation time and a largely reduced volume of magnet pole.
