## What are the three main parts of an electric motor?

Electric motor designs can vary quite a lot, though in general they have three main parts: a rotor, a stator and a commutator.

## What is the working principle of electric motor?

An electric motor utilises the magnetic effect of current. It works on the principle that when a rectangular coil is placed in a magnetic field and current is passed through it, a force acts on the coil which rotates it continuously.

## What is the function of each part of the motor?

The main parts of an electric motor include the stator and rotor, a series of gears or belts, and bearings to reduce friction. DC motors also need a commutator to reverse current direction and keep the motor spinning.

## What are two main components of an electric motor?

The two main components of this kind of motor are the stator (stationary element) and the rotor (rotating element). The stator is a fixed part of the stationary motor.

## What are the four parts of an electric motor?

The Parts of an Electric Motor

• Stator. The stationary part of an electric motor is the stator. …
• Rotor. The main moving part of an electric motor is the rotor which turns a shaft to deliver force to whichever unit is being powered. …
• Air Gap. …
• Windings. …
• Commutator.

## What is electric motor explain with diagram?

1) When electric is passed into the rectangular coil, magnetic field is produced around the coil. 2)The magnetic field of horse shoe type interacts with the magnetic field on the coil and causes the coil to rotate continuously.

## What is generator working principle?

Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. … When the coil rotates, it cuts the magnetic field which lies between the two poles of the magnet.
