The speed formula of three-phase asynchronous motor is: n=60f/p(1-s) As can be seen from the above formula, changing the power supply frequency f, the number of pole pairs of the motor p and the slip ...
Does STM32F103VET6 have DAC function? If yes, why is there no DAC output?I have been working on this for two days, and I really can't find out what is wrong below. Why is there no DA output?The DAC ou...
I did a whole day of experiments yesterday and burned 2 IGBT tubes. In the afternoon, the circuit finally worked! Hahaha, although it was hard work, I was very happy to see the equipment working....
I want to use a single-chip computer to determine whether several 220V AC motors are actually running or shut down. How should this circuit be implemented? Please share your opinions....
Do you often have to add brake fluid to your car's brakes? The fact that you need to pump out the brake fluid to make sure there is no gas in the brake fluid line may not be done by the car owner h...[Details]
