A motor is an electrical or mechanical device that converts electrical energy into mechanical energy to produce rotational or linear motion. It is widely used in machines such as pumps, compressors, fans, conveyors, hoists, and industrial equipment. The main parts of a typical electric motor include the stator (stationary part), rotor (rotating part), windings (coils), shaft, bearings, and housing. Motors can be classified into AC motors and DC motors depending on the type of electrical supply used.

In operation, when electrical current is supplied to the motor windings, it creates a magnetic field in the stator. This magnetic field interacts with the rotor, producing a force that causes the rotor to turn. The rotating rotor then drives the motor shaft, which is connected to the machine it powers. In AC motors, alternating current continuously changes direction, creating a rotating magnetic field, while in DC motors, current flows in one direction and is controlled using brushes or electronic controllers. The bearings reduce friction and allow smooth rotation. Motors are essential in modern machinery because they provide reliable, efficient, and continuous mechanical power for a wide range of applications.
