Dcbrushless mining machine fan

1. It's about 6 yuan in paipai

2. Generally, it seems that the yellow line is the ground line, the red line is the live line, and the black line is the zero line. Of course, the black line has nothing to do with the red one. You can take a look at the power supply, the top should also be the three colors, one by one on the line~~

9. I've just seen your other request for help, and "tangyyer" has said it in more detail
in short, the blue rotor angle feedback on the top realizes the brushless function, and the PI feedback on the bottom and left realizes the speed adjustment function. The whole system controls the speed of PMSM, and the given speed is the mole on the left 3000
six step, which means that an electrical cycle of PMSM is divided into six parts, and the upper blue mole establishes the stator magnetic field in these six parts in turn, which will lead the rotor magnet by a certain angle, so as to attract the rotor to rotate DC motor needs to change the direction of the brush to change the stator magnetic field)
obviously, the strength of the magnetic field can determine the attraction between the stator and the rotor, and the greater the magnetic force, the greater the rotation acceleration. Therefore, through the inverter output voltage, the current can be adjusted to determine the size of the stator magnetic field, and ultimately affect the speed.
