What is it about?
The brushless DC motor (BLDCM) is widely used in industry area. But the torque ripple affects the motor performance and generates many unnecessary troubles. We focus on the commutation torque ripple and propose the novel driving system of BLDC motor which cans significate reduce commutation torque ripple in the whole speed adjustable range. We also used SIMULINK model and experiment system to test the reliable of the driving system.

Why is it important?
The commutation reduction strategy can lower the torque ripple by about 70% compared with driving method without it. And the commutation interval and the voltage could be adjusted dynamically while the speed and load change. Using this driving system can meet some applications such as elevator industry, medical device, electric vehicles, etc.
