Electric motor is an electromagnetic device, which converts electrical energy into mechanical energy. In the same way, the electric generator converts mechanical energy into electrical energy. From an internal construction point of view, they are practically the same device, but serving two different functions.

Electric motors are present in a vast array of industrial and automotive applications nowadays. Actually, we could not understand movement in industry without the multitude of electric motors used across incredibly diverse industries.

The part that is more often replaced in an electric motor is the bearing, so efficiency and service life depend heavily on the proper performance of the bearing.
