What Can Cause Electric Motor Failure?

Electric motors can be found in many, many tools and appliances used for everything from air conditioning to welding. If a motor fails it can wreak havoc on a business, causing downtime that results in a loss of business or production value. But if you have an industrial machine shop on hand that can fix your generator, welder, pump or other electric motor the downtime can be minimized and losses unsubstantial. But what causes electric motors to fail? During an electric motor repair the service technician first needs to identify what caused the motor to stop working. The diagnosis may often fall under one of these 5 categories:

Overheating

Electric motor overheating will cause outstanding performance issues as well as complete shutdown of the motor. The excessive heat can be caused by high current issues, high exterior temperature operation, loss of a cooling fan or degrading insulation.

Dampness

If a motor is subject to moisture it will eventually cause corrosion to the main motor parts, including the motor rotors, shafts and bearings. Regularly monitor air moisture to avoid this type of damage.

Electrical Overload

If your motor begins to unexpectedly draw more current than it's standard operating capacity it can literally fry the motor. This event is generally unpredictable, but there are devices that can prevent it if installed properly.

Misalignment

If a part becomes misaligned due to corrosion, high operating speeds or some other factor the machine will begin to shake and vibrate, likely causing many other problems within the motor.

Dirt

Dirt, grime and other buildup can block cooling fans, causing the motors temperature to rise and eventually cause overheating issues. If dirt or dust makes its way to the motor windings it can also lower the value of the winding insulation. Always be sure your machines are shielded from dirt and dust.

Once the root cause of the problem has been identified the technician can then work to repair the problem, replacing any necessary parts to get the motor up and running again.
