Common Electric Motor Issues

Would you like to understand how a motor works and how to identify common electric motor issues?

Your average motor is often designed for highly-specific purposes. This ranges from basic household functions to more industrial or manufacturing tasks. In many cases, such as those where big electric motors are needed, they usually implement industrial-grade one.

Electric motor repair specialists often find themselves called upon to help. But some problems are easier to diagnose and fix than others. Read on as we discuss some of the most common electric motor issues, plus how to potentially resolve them.

Low-Speed Motor Problems

Motors are designed to operate within a specific speed range. If you have a motor running at abnormally low speeds, this could indicate several problems. One of these is an imbalance in the load or a misaligned, worn shaft.

Another could be an overloaded system. It can be from a faulty drive mechanism. Or it can be from a blocked cooling or a capacitor that is not providing the appropriate voltage.

Your motor might also be running at a low speed because of contaminated lubricants. Checking the oil regularly is an important part of a healthy motor maintenance program.

Finally, changes in the operating temperature, magnetic field leakage, worn bearings, and improper electrical connections can also cause speed variations.

Overheating Electric Motors

The major causes of motor overheating can vary depending on the motor type. But they always include current overload, air gap misalignment, and bearing failure.

Current overload can occur when the motor draws more than its rated current. As it requires a larger heat removal capacity.

But, air gap misalignments can cause increased air friction and increased heat generation. As well as improper shaft-to-shaft or drive-to-shaft alignment causing an unevenly distributed heat load.

Lastly, bearing failure is often responsible for overloading the motor, creating overheating.

Problems with Unbalanced Rotors

This can cause several problems ranging from a decrease in efficiency to mechanical vibrations. There are a couple of ways that an unbalanced rotor can come to be.

Additionally, a difference in weight between the two ends of the rotor can cause an imbalance. This makes the electric motor work harder to make up the difference. This result in increased mechanical vibrations and a decrease in efficiency.

Additionally, if the imbalance is too much, it can cause the electric motor to overheat and shut down. It is important to properly monitor and maintain electric motors to ensure the rotor stays balanced.

Causes of Wiring Issues in Motors

Poor connections, improper connections, and insufficient insulation can cause a variety of problems. Such as intermittent performance, overheating, and short circuits. If not repaired, can degrade the performance of motors and cause them to malfunction.

Poor connections and loose connections can also result in a decrease in voltage and an increase in heat. It can lead to a breakdown in the motor.

So it is important to regularly inspect, clean, and inspect motor wiring for wear and tear. As well as any loose connections or improper connections. Once identified, contact electric motor repair services like This is to ensure safe operation and the longevity of the motor.

Take Good Care of Your Electric Motor

Regular maintenance and troubleshooting can help identify problems quickly. It also maintains the lifespan of electric motors.

To keep your electric motor in good condition, it is important to regularly check the system and contact a professional for any repair or maintenance needs.
