BLDC 전동기용 센서리스 드라이브의 토크 리플 저감을 위한 전유 방법
A Commutation Strategy for Torque Ripple Reduction of Sensorless Drive for BLDC for BLDC Motors
초록
Brushless DC motors have trapezoidal back emf waveform. Generally, because it is drived by a voltage source inverter, the ideal rectangular phase current is not available and therefore produce torque ripple. In this paper, the torque ripple due to commutation is analysed and the practical method that can reduce the torque ripple is proposed. Simulation and experimental results show the effectiveness of the proposed method.
