How do you fix an electric motor?
How do you fix a overheating electric motor? A great way to do this is to use an overload relay. The role of relay is to protect the motor from overloading and overheating. If this occurs, the relay then deactivates the motor until the issue can be resolved. Some overload relays can also be developed into microprocessor systems.

What causes electric fan to stop working?
Over time, the lubricant on the pin wears down as the fan blades rotate. Re-oiling the pin will usually solve this problem. A dried out or sticky pin is one of the most common reasons for blades to stop spinning. If they spin easily and there's no resistance, try turning your fan on and see if the pin spins.
How do you fix a fan that won't rotate?

Can you fix a burnt out fan motor?
Motor Rewinding Procedures If an electric motor operates at too high a voltage, excess current flowing through the windings can cause them to become hot and burn out. While it is normally not practical to repair small, direct current (DC) motors that have burned out, other motors can be repaired by rewinding.
What is the common problem of electric fan?
Fan tends to overheat. This kind of problem is quite alarming since it might cause the appliance to break or even blow up. However, for electric fans, this is ironically a common problem but might be due to using the electric fan for a long period of time while maximizing its maximum speed.

Cooking oil will "gum up" after a while and the fans will literally stop spinning. Machine oil is better, but even then, it can catch dust and ultimately increase friction. Your best solution is simply to replace the fan, if it is noisy.
What causes a electric motor to burn out?
The most common cause of motor failure, and arguably the most difficult to overcome, is low resistance. Low resistance is caused by the degradation of the insulation of the windings due to conditions such as overheating, corrosion, or physical damage.

The capacitor in a fan is often similar in shape to a resistor -- cylindrical with a wire at each end -- but it's a solid color. You'll usually find it soldered to the coil, although you may have ...
I can hear the motor on the fan it starts to turn but won't
You need to change your fan's bushings. Bushings hold the armature centered on the core winding of the motor. When one or both bushings are worn out, applying power on the motor will pull the armature to one side and cling to the core winding instead of making the armature turn.

An electric fan will not work because of a worn-out bearing or bushing. This is normal in a device whose work involving a constant moving inside parts. Eventually that part shall worn-out in time.
2. Improper Propellers Sitting
As explained earlier, one of the causes that your fan is not working because of a worn-out bearing. There is also a case where the bushing might not installed properly.
3. Disconnected to Power Source
Another factor that may cause your electric fan not working is that may be a problem with the power source. If no electricity run powering than there is no way that electronic device can work.
4. Dry or Jammed Countershaft
When you’re experiencing a buzzing sound from your electric fan and the propellers are also not rotating, it may be caused by the countershaft is dry or even jammed. This condition happens because it is covered by dust and eventually clogging the run way of the shaft.
Why does my Electrc motor overheat?
If your electrc motor is an "open" design you can see into the motor housing; look for clots of dust and oil that may be blocking the cooling fan and causing the motor to overheat; overheating can cause the motor's thermal overload switch to shut the motor off (and the switch may pop out waiting to cool-down and re-set).

Press the button to turn the fan off and on again , this time listening closely for the motor. If you hear it humming or buzzing, your motor is likely still functioning.
How to fix fan that is sticking?
Turn the pin on the front of the fan with your hand to see if it rotates. Use your hand to try turning the pin in the middle of the fan. If it’s sticking or resisting, the pin probably just needs lubrication. Over time, the lubricant on the pin wears down as the fan blades rotate. Re-oiling the pin will usually solve this problem.
How to unscrew a fan pin?
With the pin exposed, there may still be 1-2 metal bolts locking the pin around the frame of the fan. Use a wrench to unscrew these pins and loosen them. You don’t need to remove the completely, but you do need to be able to get underneath them to reach all of the pin.
What is the pin on a fan?
If it loosens, unscrew it and set the front of the blade case down. The pin is the piece of metal in the center of the fan that the blades and case rotate around. The blade guard, or blade casing, refers to the plastic or metal case that keeps people from getting hurt by the blades.
How to remove fan blades?
Turn the blades or washer in the center of the fan counterclockwise to remove them. Every fan is different, but the blades are either locked in place with a small washer on the pin or by the case of the pin itself. If there is plastic blocking the center of the blades, twist it counterclockwise until it comes loose and slide the blades off. If there is no washer, twist the base of the blades while holding the pin in place to loosen them off of the pin.
