Principle of the table fan motor
The energized coil of a table fan motor rotates in a magnetic field. The motor of a table fan motor is composed of a stator and a rotor. In the model, the stator is an electromagnet, and the rotor is a coil. The stator and rotor use the same power supply, so the direction of the current in the stator and rotor of the table fan motor is always synchronized, that is, the direction of the current in the coil changes, and the direction of the current in the electromagnet of the table fan motor is also According to the left-hand rule, the direction of the magnetic force on the coil of the table fan motor remains unchanged, and the coil can continue to rotate.
Use a multimeter to repair the table fan motor
First, measure the red and black leads of the table fan motor. If it does not conduct, it indicates that the table fan motor may be repaired. The remaining 3 wires are all conductive. This result can be seen by disassembling the table fan motor case.
After disassembling the motor case of the desktop fan, you can see that the coil has no traces of scorching. However, there is a white square part on the outer surface of the coil of the table fan motor, and it is found to be connected with an external black wire along with the lead of the part. This component is the temperature safety resistor.
Use a multimeter to measure the motor components of the table fan, and it is in an open circuit state. At this time, the component can be short-circuited, that is, rotate the component once to twist the two legs of the component together.
At this time, measure the red and black wires of the table fan motor. At this time it is turned on. Then test the other 3 wires are still on. This indicates that the temperature fuse of the table fan motor may be disconnected and the motor will not rotate.
Install the table fan motor as it is. When the rotating shaft of the table fan motor is flexible, it can be connected to the power supply and the capacitor, and the motor starts to rotate when the motor is turned on. The fault of the table fan motor is eliminated.
Precautions for table fan motors
Qualified table fan motors have this temperature insurance. Repair is necessary when the coil of the table fan motor is not burnt. Only hands-on experience in repairing table fan motors. Use electricity safely, and be careful of the leakage of the table fan motor.
It can be seen from products such as table fan motors that table fan motors play a key role in the development of our related industries in terms of quality.
