6 Reasons that Electric Motors Fail

For your shop to run smoothly and your projects to get finished on time, you need to be able to rely on your tools and equipment that are powered by electric motors. To ensure the proper function of an electric motor, it's helpful to know what might cause it to malfunction. Here's a look at six common causes of electric motor failure.

Electrical Overload

The motor could fry if it draws more current than it requires for operation. To prevent this from happening, you can invest in an overload protection device.


Overheating can cause the motor to fully shut down. This issue may occur due to cooling fan trouble or poor insulation. Excessive current draw could also be to blame.


If an electric motor is exposed to damp conditions, there's a good chance that corrosion issues could develop in the shaft and bearings. Because rust can cause significant engine problems, you'll want to prevent moisture exposure whenever possible.


Dirt and sawdust can obstruct the cooling fan, which could consequently cause your motor to overheat. Dirt and grime can also cause problems by compromising the effectiveness of winding insulation.


Corrosion or high operating speed could cause the motor to start shaking badly. Misalignment may then result, which could consequently cause other issues.


It's important to always make sure that your device is correctly mounted. Otherwise heavy vibrations could cause bearings to degrade.
