| Abstract: | The direct detection of back electromotive force （EMF） in position sensorless BLDCM control system based on ST72141 is improved. And two improved detection method as well as the principle for low-speed or low-voltage and for high-speed are given. The results show that combining with the two methods, the range of velocity of the motor is widened and the system performs well and has high stability and reliability. The machining accuracy of the processing system with the two methods applied improves a level of order of magnitude. |
| Keywords: | direct detection of back EMF zero crossing detection of back EMF detection of terminal voltage PWM |
