Toay, A.N. tells us about AC motors/electric motors and the causes of faults. If like him you want to discuss a topic that you like, send us a mail and we will publish it after a short review!

Failure in electric motors may occur at start-up or during operation. Most of the electric motor failures occur at start up due factors such as low insulation resistance, over-current or mechanical failures. Other causes include issues with the supply, operation environment or lack of maintenance.

Most of the motors, regardless of type and rating have a long service life and only require a minimum maintenance to ensure they do not malfunction. It is recommended to regularly maintain the motors and associated equipment, and to check for signs of aging of the insulation or other parts that may degrade the motor.

electrical cables
Hello everybody, enjoy this article from one of our fellow members of the community! And if you have remarks or questions to ask, do post them in the comment section.

Joining electrical power cables can be as simple as twisting the wires and taping them or more detailed using a variety of inline adapters and connectors. The method used for a particular joint depends on the voltage, type of cable, type of joint, type of connector, application and other factors.

Regardless of the method used, it is important to have the proper tools and materials. Some of the key factors that ensure clean, safe and reliable connections are;

  • Using the proper size of the connector for the particular cable
  • Proper tools
  • Clean cuts and stripping
  • Restoring the insulation, armor and outer-sheath
  • Proper technique
