Analysis and Simulation on Torque Ripples of Brushless DC Motor
Abstract: Because of its small
size, high reliability, efficiency, and its output torque characteristics, brushless
DC motor (BLDCM) had been widely used in many field of robotics, precision
instruments andequipment, etc. However, its inherent electromagnetic torque
ripple limited the scope of its application,which was the focus and difficulty
of its research in recent years. This article first described the causes ofbrushless
DC motor torque ripple, and then torque ripple generated by four PWM
modulations wasanalyzed to get optimum control scheme, finally the MATLAB /
SIMULINK simulation model verified theanalysis of the results. This paper
provided the most intuitionistic exhibition.
