코깅토크 저감을 위한 Spoke Type BLDC 전동기의 새로운 극 형상 설계

Abstract

This paper proposes a design method by varying rotor pole shape to reduce cogging torque, torque ripple and harmonics of back emf in Spoke type brushless DC(BLDC) motor. In the process of design and analysis, Response surface method(RSM) and finite-element method(FEM) are employed to get the rotor geometry and verify the results of new pole shape.
