Electric motors are found in many types of power tools and heavy machinery, from chainsaws to lawn mowers. To protect your safety while operating this type of equipment, watch out for any issues that may require professional repair. Below are a few of the most common warning signs of a faulty electric motor.

3 Signs of Electric Motor Problems

1. Random Shut-Offs

If your equipment shuts off randomly while working on a project, a component within the electric motor is likely short-circuiting or overloaded. Check the extension cord to rule out any external problems.

2. Darkened Paint

If there are areas of darkened paint on the electric motor or its casing, this is a sign that your motor is overheating. It may be due to a lack of airflow or excessive current. Either way, the motor must be diagnosed and serviced by a technician to prevent it from failing, which would require a full motor replacement. 

3. Excessive Vibration

Malfunctioning bearings or loose mounting bolts cause excessive electric equipment vibration during operation. Other components within the motor may also come loose, which leads to other issues such as motor failure. Schedule an appointment with a technician, so they can tighten the internal components.

4. Unusual Sounds & Smells

Sounds such as screeching, grinding, or crunching signify electric motor damage. Screeching may be caused by a loose screw or worn bearings, and grinding is the sound of worn moving parts rubbing together. Burning smells are also a red flag and indicate that the motor is overheating.
