Reasons An Electric Motor Failure Can Occur

Electric motors are used in a wide variety of different appliances and products. For example, ceiling fans, washers, refrigerators and air compressors all use different types of electric motors to run properly. However, sometimes an issue with the electric motor can occur and the appliance may no longer work as it should. The following are some common reasons for electric motor failure.

Electrical Overload 

Even if an electric motor has been working fine for a long time, sometimes it will begin to pull a stronger electrical current from the power source than it can handle. Unfortunately, this can cause one of two things to happen: the motor will stop working, or a spark will be triggered and a fire could occur.

However, many of the newer power outlets come with a special device installed that will cause the outlet to kick off when this occurs. When the appliance or other electrical unit plugged into one of these power outlets begins to overload, the outlet will kick off and electricity will no longer flow to the electrical motor.

Over Heating 

Electric motors produce heat. However, each electrical motor has an ideal temperature that keeps it working properly. If the motor begins pulling a stronger current than it normally uses, this can increase the motor's temperature substantially. If the motor overheats, it cannot continue to run.

The electrical motor of any appliance should be kept in a well ventilated area. If not, the surrounding temperature can cause the electrical motor to overheat and stop working correctly.

Dirt & Dust 

When dirt and dust clogs an electrical motor, it can cause the built-in cooling fan to stop running. This causes the motor to overheat and stop running. Dirt and dust can also settle on the windings of the motor and this prevents it from running properly. Wiping the dirt and dust off the motor on occasion can help keep these clogs from occurring and keep the motor running smoothly.


An electrical motor should be protected from the elements of the weather at all times. Being exposed to rain, snow or other dampness can quickly cause the motor shaft, bearings, and rotors to rust and corrode. If the motor cannot be stored indoors, it should always be covered tightly with a weatherproof tarp.

Depending on the severity of the damage, a motor may be able to be repaired. It will first need to be disassembled to assess what the damages are. Often an older motor can be rebuilt and continue to work properly just as long as a brand new motor. For more information, contact a professional like Hackworth Electric Motors Inc

About Me

updating electrical work in an older home

I knew before I bought an older home that it would require a lot of work. What I didn't expect was to find the the entire second floor of the home had inadequate electrical work and that it would all have to be updated to keep my family safe and conserve some energy. I created this blog as I worked to overhaul my house and redo the electrical mess that I uncovered. You will find out what should be and what should never be done when working with electricity in older homes and what you can do to ensure the safety of your family while living in your home.
