Electrical motors can last a long time when they’re properly maintained by an electrician. While they’re known to be reliable, they can still malfunction just like any other type of machine. Know the most common causes of failure so you can take the appropriate prevention or repair steps. The extra perspective will keep your motor humming along when you need it.

Electrician Guide to Motor Failure Causes

1. Overheating

High temperatures will cause electrical equipment to fail; every 10 degrees Celsius that a motor is above its ideal temperature, the insulation life of the components will drop by 50%. Prevent this by keeping your motor running at the optimal temperature. Keep it in air-conditioned areas when possible, and be sure to always store it out of direct sunlight.

2. Contamination

Contamination may occur from dust, dirt, rust, and other particles. When they get into the electrical components, they can cause problems ranging from interference with the current to abrasion and corrosion of the components. Prevent this by having your electrician place the motor in an enclosure that is ingress-protected.

3. Power Surges

When too much of a current runs through the motor windings, it can fry the components, or the motor may automatically shut off to protect the components. Have your electrician install a variable-speed drive in your motor so it can handle power surges without becoming damaged or shutting off.

4. Low Resistance

Low resistance occurs when the interior insulation deteriorates too much; issues such as heat will make this happen more quickly. The lack of insulation between the conductors and motor windings can result in short circuits and leakages. Have your insulation inspected regularly by a certified electrician on a schedule based on your motor type and usage.
