6 Causes of an AC Motor Failure

An AC motor is driven by an alternating current. It possesses an outside stator with coils supplied with AC (alternating current) to produce a rotating magnetic field and also an inside rotor that produces a second rotating magnetic field. 

AC motors provide quite an edge over DC motors in terms of longevity, durability and power consumption. However, maintaining an AC motor is equally challenging. In this blog, we highlight major reasons that can lead to the breaking down of your AC motor.

Overheating:
One of the main causes of AC motor failure is overheating. When an AC motor overheats, it can cause the winding insulation to break down, which can lead to a short circuit. If the motor is not properly cooled, it will eventually overheat and fail.

Vibration:
Another common cause of AC motor failure is vibration. Vibration can cause the winding insulation to break down, which can lead to a short circuit. If the motor is not properly supported, it will eventually vibrate and fail.

Corrosion:
Corrosion can also cause AC motors to fail. When the windings are exposed to moisture, they can corrode. This can eventually lead to a short circuit.

Dust and Debris:
If the windings are exposed to dust and debris, they can eventually become clogged. This can cause the motor to overheat and fail.

Electrical faults:
Electrical faults are another common cause of AC motor failure. If the winding insulation breaks down, it can lead to a short circuit. If the motor is not properly wired, it can also experience electrical faults that can cause it to fail.

Lubrication:
Proper lubrication of an AC motor is quite important. In many cases, over and/or under-lubrication is the prime cause for damaging an AC motor.
