Bread Shape 영구자석을 갖는 Brushless DC 전동기에 대한 자계 특성 해석

This paper deals with a magnetic field analysis on brushless DC(BLDC) motor with bread shape permanent magnet. In order to analyze the magnetic field, multi-layer analysis based on space harmonics method is employed. Finally, the analytical results are validated by non-linear Finite Element Analysis(FEA).
