Electric Motors: the context

Electric motors are rotating machines composed mainly of a stator and a rotor (see figure No. 1), which through the action of magnetic fields generated in their coils (located in the stator) convert electrical energy into mechanical.

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.
