The electric fan does not turn after starting, the starting capacitor is not broken, the motor is noisy, and the coil is heated, but it does not turn.

Ordinary electric fan motors have no ball bearings, but now ordinary small motors are oil-free bearings (the shaft sleeve will move back and forth), which are powder metallurgy. Is there any noise when it is not started or after it is turned? There are two possibilities: one is that the capacitor is broken and you can run by twisting the shaft with your hand; There is also a big gap between the shaft sleeves. There is no need to repair the shaft sleeve when it is worn. It is difficult to buy such a set. General fan motors 18-25 yuan can be bought, and there are many on Taobao.
