Reduction of Vibration and Noise of BLDC Motors by Realizing Sinusoidal Air-Gap Flux Density Distribution

BLDC 전동기의 정현적 공극 자속밀도 구현에 의한 진동.소음 저감

Cogging torque is often a principal source of vibration, noise and difficulty of control in BLDC motors. Therefore, this paper will present a design method of magnetization system with sinusoidal air-gap flux density distribution of Nd-Fe-B magnets in ring type for reduction of Vibration and Noise and low manufacturing cost.
