Phase-field 모델을 이용한 매입형 영구자석 모터 고정자의 토크리플 저감 최적설계

This paper presents a new design optimization method that is applicable to design of interior permanent magnet(IPM) motor for torque ripple reduction. To control the complexity of optimal design and increase the productivity, phase-field model is introduced in optimization problem. In order to validate the proposed method, the stator part of a IPM motor which is developed for a power source of hybrid vehicle is optimized by different coefficient of complexity τ.
