Abstract :
Sensorless control technology has been a hotspot in the area of BLDCM control. In this paper, a speed controller of BLDCM based on MC56F8013 was researched using BEMF-crossing-zero-detecting method, including hardware circuit and software design. Experiments were implemented and it shows that the BEMF method for detecting rotor position signal is accurate and reliable, BLDC motor can commute and run correctly.
