The electric fan does not turn. I need help turning the fan blades, but it starts spinning again.

Introduction The electric fan does not turn. If you need help, the fan blades will start to spin once. What's wrong ? Turn the fan blades by hand when the power is off (or turn it on then off). by the hand)

The electric fan does not turn. I need help turning the fan blades, but it starts spinning again.

Turn the fan blades by hand when the power is off. If they are tight (or the fan blades stop quickly after turning it on and off by hand), your fan may not have been lubricated. for a long time and it is difficult to start. Injecting lubricating oil can solve the problem; if it's not waterproof, the capacitor is broken and you can simply replace it.

Sewing machine oil, gun oil, diesel engine oil, and gasoline engine oil can all be used as lubricants. However, it is better to disassemble the motor and clean the motor shaft with fine sandpaper first. refuel, as it will take a long time

If you do not add oil and the fan motor heats up very much, a layer of dirt will form on the motor shaft.Even if you add oil, the motor will pmay not work properly

If the single fan rotates slowly (especially the fan blades stop immediately after turning off the electric fan), then it is necessary to add lubricating oil to the electric fan. Lithium-based solid grease is ideal for electric fan lubricants.

Detailed information:

Common faults:

1. The fan shaft must be lubricated, otherwise the motor with the blades on it cannot move. If you are at home, you can choose to turn off the power and then spin the fan blades. If the rotation is stiff, there is almost no lubricant.

2. Wear and tear caused by long-term use. If a fan is used for a long time, the motor will wear out, and the motor bushing will burn easily after wear.

3. The fanIt does not turn due to overheating. There is a motor in the fan and there will be an overheat breaker in the motor. If a short circuit occurs in the coil winding, the heat will increase in a short time and the motor will "knock" and stop moving. .

4. The capacity of the starting capacitor becomes smaller. When the fan is used for a long time, the capacitive capacity decreases, resulting in a decrease in the starting torque of the motor and the inability to drive the load.

5. Often the reason fan blades don't spin is due to poor maintenance. If the fan blades spin stiffly after turning off the power, you need to pour some lubricating oil into the shaft so that it can be lubricated so that it does not prevent the motor from sliding the blades of the fan.

Lubricating oil is a liquid or semi-solid lubricante used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and machined parts. It mainly functions as lubrication, auxiliary cooling, rust prevention, cleaning, and sealing and buffer functions.
