4 Reasons that Electric Motors Overheat

Overheating is an issue that commonly causes major electric motor trouble. When an electric motor overheats, it can suffer a loss of motor winding insulation, at which point the motor is liable to burn up. In such a scenario, you'll probably need a new motor. By being familiar with common causes of electric motor overheating, you can take measures to reduce the risk of such a problem arising. Here are four common causes of electric motors overheating.

Clogged Vents/Ducts

Before using electric motor-powered machinery, you'll want to do a quick inspection of vents and ducts to make sure they're not clogged up. If there is significant clogging, then heat could get trapped inside the machine and air might not be able to enter to provide cooling. This is a common cause of overheating, but fortunately it's also easily preventable.

Constantly Turning On and Off

You'll want to check your operating guidelines to see how frequently your electric motor can be turned on and off. Exceeding this amount can significantly stress the motor and heighten the risk of overheating.

Environmental Problems

If you're working in an environment that is excessively hot or humid, there's a greater possibility of overheating occurring. High altitude is another environmental factor that could increase this risk. You'll also want to make sure that you're not operating in an area that is high in chemicals that could be abrasive to the motor's parts.


You should always know the proper operating load level for your motor before commencing use. When overloading occurs, there's a good chance that winding and bearings will suffer serious damage.
