The reason for the small usb fan not turning?
1. The fan plug is loose or the wire is broken. When the fan stopped spinning, we responded that the plug was loose. At this time, you can try to re-insert the socket to confirm. Then check whether the wires of the electric fan are broken. If the wires are broken or frayed, it is likely that the copper wires in the wires are broken and the power cannot be supplied.
2. The electric fan motor lacks lubricating oil. The core component of the electric fan is the motor. Only the rotation of the motor shaft can make the electric fan rotate. After using for a period of time, the electric fan will be difficult to rotate due to the lack of lubricating oil on the rotating shaft, resulting in the electric fan not rotating. In the case of power failure, turn the fan blade by hand, if the rotation of the fan blade is relatively sluggish, it can be judged that the motor lacks lubricating oil.
3. The thermal fuse of the electric fan motor is open. If the temperature of the electric fan motor is too high and the short circuit will cause the thermal fuse of the motor to overheat and burn out, this is set by the electric fan for the protection of the motor. The thermal fuse is located on the coil of the motor, if the thermal fuse is broken, it means that the fuse is broken and the fan does not turn because of this.
