Five Common Reasons For Electric Motor Failure

Electric motors are more successful and advantageous as compared to traditional engines. These motors 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.

Electric Motor Failure Causes

Below are five common reasons for electric motor failure :

Heat

  • Receiving high amounts of heat is one of the top reasons for motor dysfunction or failure. Exposure to optimal temperature leads to a longer lifespan of an electric motor.
  • In addition to that, if your electric motor functions abnormally due to other issues, it can also lead to the generation of excessive heat, which again causes increased 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 of dust can destroy them.
  • The presence of dust and other pollutants can destroy the electric motor parts and can lead to its abnormal functioning.
  • It could either lead to corrosion or abrasion of electric motor parts and disrupt the current running inside it.

Presence of moisture :

  • In a basic electrical component, the involvement of moisture can result in damage to that particular component. Still, when we talk about electric motors, the presence of moisture can have extreme consequences.
  • When particles present in the air mix with moisture, it leads to the formation of highly corrosive substances that directly hampers the lifespan of electric motors.
  • Ensure to store your motors safely when you are not using them; else, 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. Low resistance is caused due to overheating of parts, corrosion, or other physical damages.
  • This disturbs the isolation between motor windings and conductors, resulting in short circuits and leakages, thereby leading to motor failure.
  • The only possible solution to low resistance is to check the signs of wear and tear of the motor 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 non-positioning of the motor or the motor being placed on a bumpy surface. In addition to that, it can also cause loose bearings, corrosion, and uneven alignment of the motor.
  • To protect your motor from vibration, you must inspect your motor regularly through a motor examining tool. Also, make sure to place your motor on a flat surface and avoid any such unstable surfaces.
