분할코어를 적용한 EPS용 SPMSM의 극, 슬롯 수에 따른 조립공차에 의한 코깅토크 분석

Abstract

As interest in the environment increase, the automobile parts market is increasingly trying to change from the mechanical system to the electrical system. In order to replace the mechanical system with the electrical system, many studies have been conducted to improve the performance of the electrical system because the electrical system must perform better than the mechanical system. However, there are few studies on tolerances that occur during actual production compared to studies on improving electrical performance. Due to the tolerances that occur during production, products with lower performance than actually expected can be produced. This paper intends to confirm the change in motor cogging torque due to the stator inner diameter tolerance applied to the segmented core, which is frequently applied to motors.
