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;
Dear masters, in order to reduce power consumption, I hope to convert the 7-segment svpwm into a 5-segment svpwm. Please give me some guidance. Thank you. I know how to calculate the five-segment comp
The switching power supply chip OB2202, the 3rd pin for detecting current will slowly increase the feedback voltage over time, and according to the information on the Internet, it is found that it has
