The ceiling fan cannot run without a motor. As the motor rotates, blades connected to the rotor winding of the motor will spin. Generally, in every ceiling fan, a Single Phase Induction Motor is used. However, the indoor ceiling fan motors rarely fail.
How to tell if ceiling fan motor is bad?
There are some reasons for the failure. If the ceiling fan motor goes bad, the fan will not spin, there will be a short circuit in the ceiling fan. One more problem due to the bad motor could be humming noise.
Let us discuss some of the reasons in detail and how to fix them.
Bad Ceiling Fan Motor – Reasons & Solutions
Voltage Fluctuation
The performance of the ceiling fan motor depends on the power supply and voltage given to the motor. If there are any voltage fluctuations or any issue with the power supply, it will affect the motor. You can check motor specifications and user manuals, to provide a nearly accurate power supply to the motor.
Overheating of the fan Assembly and Burning of the Insulation
The temperature in the motor will increase if you run the fan for a long period. The high temperature for a long time will overheat the motor. Because of overheating, the insulation between two windings will burn, and there will be a short circuit of two windings. If this is the problem, you will need to rewind the windings.
Loss of Lubrication
Lubrication means filling the oil in the lubrication chamber of the ceiling fan. There are two purposes of lubrication. The first one is for cooling the fan assembly and the second is for the smooth rotation of the motor. If the lubricant loses after a certain duration. Therefore you need to lubricate the fan. Otherwise, the motor will not perform with its efficiency.
Bad Bearings
Without bearings, the motor will not rotate. If the connected bearing is not in good condition, it will affect the motor performance. Bearings will collect the dirt and dust if the fan is turned off for a long time. Clean the bearings regularly to maintain motor efficiency. The second problem can be the wear and tear of the bearing. If it happens, replace the bearings with new ones.
Wrong Wiring
Incorrect wiring can affect the rotation of the motor. So check the wiring and make it correct for the accurate rotation of the motor. If the connections are loose, the motor will not run. Check the connections and tighten the wires for the proper running of the motor, if you could not notice the loose connections or wrong wiring, the motor may go bad. Furthermore, make sure the capacitor is connected properly and is not faulty.
Health of Windings
There are two windings in the ceiling fan motor namely, Stator and rotor winding. These windings have a specific value of resistance. Due to the wear and tear of the windings, there will be a change in the resistance of the windings. It will affect the efficiency of the motor. To verify this, take the multimeter and check the resistance of the windings. If the multimeter shows infinite resistance for every wire, then consult an electrician.
Final Words
The ceiling fan motor can go bad because of the above reasons. You should have got sufficient information for the same in this article.
