Optimal Design of Tooth and Yoke Width Using Equivalent Magnetic Circuit in Concentrated Winding Motor

등가 자기회로를 이용한 집중권 전동기의 치폭 요크폭 최적설계

This paper presents optimal design of tooth and yoke width for increasing torque density when designing concentrated winding Interior Permanent Magnet Synchronous Motor(IPMSM) which is used currently. In case of IPM, characteristic of motor chages according to saturation, thus design consib dering saturation should be done. This paper proposed method to decide tooth and yoke width using magnetic equivalent circuit with calculated magnetic resistance. This method provide less effort and time than FEM using optimal design when deciding tooth and yoke width. Proposed method and FEM are compared and verified.
