SAQ : Describe an electric motor




Describe an electric motor.



An electric motor is a device that converts electrical energy into mechanical energy. It works on the principle of electromagnetic induction, where a magnetic field is generated by passing an electric current through a coil of wire, which then interacts with a magnetic field to produce rotational motion.

The basic components of an electric motor are a stator (stationary part) and a rotor (rotating part). The stator consists of a frame or housing, and one or more coils of wire usually arranged in a circular pattern around the rotor. The rotor consists of a shaft and a series of magnets or magnetic poles, which interact with the stator’s magnetic field to produce rotational motion.

When an electric current is passed through the coil of wire in the stator, it creates a magnetic field that interacts with the magnets in the rotor. This interaction creates a force that causes the rotor to rotate, and the rotational motion is transferred to the motor’s mechanical load.
