Electric motors are used in a wide variety of applications, from fans and fitness equipment to generators, welders, and industrial conveyor belts. With proper care and maintenance, you can prevent premature breakdowns and maximize their lifespan. However, eventually, all electric motors will become worn and inevitably need to be replaced. Here are a few signs to identify that will help you with early detection of motor failure, reduce equipment downtime, and avoid emergencies.

How to Know When It’s Time to Replace Your Electric Motor

1. Vibration

Constant and excessive vibration can make it unsafe to operate your machine or appliance. This is usually the result of damaged windings or bearings, loose mounting bolts, corrosion, or a misalignment within the electric motor. The shaking could also cause other parts inside to come loose and lead to serious motor damage. In most cases, vibration is a major clue the motor is faulty, but a professional inspection will confirm if a replacement is necessary.

2. Overheating

When an electric motor is failing, it’s common for it to overheat on a consistent basis. You may notice dark burn marks on the motor’s paint or its casing. This could be a simple fix due to an airway obstruction. Although, if you have it repaired and the overheating continues, it’s best to invest in a new motor. Over time, the overheating will begin to burn or warp other components of your equipment.

3. Short Circuiting

Insulation deterioration is another indication that an electric motor is preparing to fail completely. This is caused by use at high temperatures, thermal stress, moisture, and environmental contaminants. Once a motor’s insulation becomes worn, it will usually start short circuiting and sending excessive current through the motor windings. In turn, the motor will experience an electrical overload.
