The BLDC I am using now is a tachometer motor + Hall. I collect the voltage of the tachometer motor signal as the speed information after passing it through a rectifier bridge. However, when the speed...
After a failure, I became conservative. After making all the links safe, I finally drove the motor~~~First, I considered several possible reasons why the resistor may have burned out:
1. Device aging;...
For high-voltage H-bridge PMW motor drive, power MOSFET and IGBT are mainly used as switch tubes, and the drive circuit of the switch tube usually adopts integrated drive circuit to convert the PWM co...
