What Causes Electric Motors to Overheat?

One of the biggest threats to electric motors is overheating. Excessive heat can lead to premature loss of the motor winding insulation resulting in the motor burning itself up. If a motor overheats there is a good chance it will need to be completely replaced, rather than repaired, in order to restore operation of the machine that it powers. To ensure you don't lessen the life of any machines you use make sure the electric motors don't suffer from these following conditions that are found to be the most common causes of electric motor overheating.

Environmental Issues

It is important that the environment in which you run the motor is free of any excessive chemicals that may be abrasive to the motor's parts. However, it is important to be aware of the general conditions the motor is operating in. Excessive heat, moisture or operating at a high altitude can all increase the chances of overheating.

Repetitive On and Off

There are certain standards set for most motors about how often the on/off switch should be thrown. Going above these recommendations can put much stress on the motor which may result in overheating.

Overloading

To avoid excessive heat caused by high current it is imperative that you have proper knowledge of the operating load level of your motor. While perfect voltage conditions are rare in many industrial applications, accurate load calculations will provide reliable measurement of voltage. Overheating can cause major damage to winding and bearings.

Clogged Vents

Unfortunately one of the most common causes of overheating is also one of the most preventable. Be sure to check ducts and vents of the machine prior to each use to ensure they are not clogged. Clogged air ducts trap heat and prevent fresh air from helping to keep the motor cool.

Overheating of electric motors can result in a number of problems, including complete engine failure.
