In the hot summer, it is time for all kinds of electrical appliances to come into play. Among them, the fan is the most cost-effective product. Although it is not as comfortable as the air conditioner, it saves electricity and is suitable for one person. Do you know how to deal with the phenomenon that the fan at home is slow to start and cannot start? Let's take a look with the editor to see what is the reason for the slow start of the electric fan and how to solve the problem of the slow electric fan.
1. Working principle of electric fan
If you want to solve the problem of the slow speed of the electric fan, you should first understand the working principle of the fan, and then repair it. The main working principle of the fan is that the energized coil rotates under force in the magnetic field. The electrical energy is converted into mechanical energy, and the fan blades are rotated. At the same time, due to the coil resistance, some heat energy will be generated, so the surface of the general electric fan will be hot if it is used for a long time.
Second, understand the reason why the electric fan does not turn
After understanding how the fan works, the next thing to do is to find out why the fan is not spinning. The reasons for the electric fan itself may include that the fan blades may be too long, and the internal resistance of the motor increases, causing the fan blades to fail to rotate normally; the overheating of the fan causes the motor’s load capacity to deteriorate, resulting in the inability to rotate; the protection device inside the motor is overheated short circuit, etc. Another possibility is that the external power supply is not plugged in properly, or the switch is broken.
3. How to repair the electric fan if it does not turn
The repair is to first check the external reasons. Then deal with it one by one. If the fan blade does not rotate, turn off the power supply and add some lubricating oil to the shaft of the fan blade rotation; other problems may involve the replacement of the shaft sleeve, the replacement of the capacitor, the adjustment of the gasket, and the replacement of the wire if the wire is damaged. It is necessary to ask a maintenance master to repair it, and the cost is generally less.
