introduction：Fan oscillation、Air conditioning swing is mainly on the motorThe direction of rotation is not required，This kind of synchronous motor has simple structure，Low cost，Long life，Such a small asynchronous motor is more expensive than a synchronous motor，Such as microwave ovens and air-cooled refrigerators for the cover pole asynchronous motor，Complex structure，Have a cast aluminum rotor，Synchronous motors are much cheaper in price。And the vibration motor rotation direction is not required。 Connection analysis： Red, white, and blue, any of the three speed lines will do，Choose one to connect to the black line，The yellow wire connects to one end of the capacitor，Connect the other end with a black wire，This way the motor can run。 Pay attention to the red line，Next is the white line and the blue line is slow，Its for the fan3Individual speed。
