Abstract

Compared to 3D FEM, 2D FEM can be analyzed by simplifying the model and conditions. However, with respect to coil conditions, in many cases, direction of coils(upward, downward, entrance, exit, etc.) are sequentially configured and set up the FEM analysis conditions. This paper shows simplification of coil conditions and reduction of analysis time by applying the equivalent winding method composed of one FEM coil even if it has multiple slots, and shows consistency of results by applying it to a winding type magnetic gear.

2D FEM은 3D FEM에 비하여 모델 및 조건을 간소화하여 해석할 수 있다. 하지만 코일의 조건에 대하여는 실제 코일의 인입과 반출을 순차적으로 구성하여 해석 조건에 입력하는 경우가 많다. 본 논문은 다수의 슬롯을 가지더라도 하나의 FEM Coil로 구성한 등가 권선법을 적용하여 코일 조건의 단순화 및 해석 시간의 단축을 나타내고 권선형 마그네틱 기어에 적용하여 결과의 일치성을 보인다.
