Five Common Reasons For Electric Motor Failure

Electric motors are more successful and advantageous than traditional engines. They are very reasonable and have fewer moving parts, thereby having extended life. In addition, an electric motor is very efficient and has automatic functions. Also, they require a limited amount of maintenance. Even these motors do not need fuel to run. Perhaps no such engine oil or battery service is required.

Below are five common reasons for electric motor failure :


  • One of the top reasons for motor dysfunction or failure is receiving high amounts of heat. Exposure to optimal temperature leads to a longer lifespan of an electric motor.
  • In addition, if your electric motor functions abnormally due to other issues, it can also generate excessive heat, which again increases the chances of motor failure.
  • If the electric motor is exposed to 10°C heat or more than that, it will damage your electric motor.

Damage due to dust particles :

  • It is often advised to keep your electric motors away from dust particles and other contaminants because even the slightest dust can destroy them.
  • Dust and other pollutants can destroy the electric motor parts and lead to their abnormal functioning.
  • It could lead to corrosion or abrasion of electric motor parts and disrupt the current inside.

Presence of moisture :

  • Moisture can damage a basic electrical component. Still, when it comes to electric motors, moisture can have extreme consequences.
  • When particles in the air mix with moisture, highly corrosive substances form, directly hampering the lifespan of electric motors.
  • Store your motors safely when you are not using them; otherwise, coming in contact with moisture will destroy them.

Resistance :

  • One of the major reasons behind electric motor failure is low resistance, and it is the most complicated one to overcome. Overheating parts, corrosion, or other physical damages cause low resistance.
  • This disturbs the isolation between motor windings and conductors, resulting in short circuits and leakages, which can lead to motor failure.
  • The only possible solution to low resistance is to check the motor’s signs of wear and tear and be immediately replaced as and when required.

Failure due to vibration :

  • When your electric motor starts to vibrate, it can lead to other issues and permanently destroy the motor.
  • The main reason behind vibration is the motor’s non-positioning or its placement on a bumpy surface. In addition, it can also cause loose bearings, corrosion, and uneven motor alignment.
  • To protect your motor from vibration, you must inspect it regularly with a motor examining tool. Also, make sure to place your motor on a flat surface and avoid unstable surfaces.
