# What is electric motor and how does it work?

Contents

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.

## How do electric motors work?

Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current.

## What are electric motors used for?

An electric rotor. An electric motor is a device used to convert electricity into mechanical energy—opposite to an electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field.

## What is the working of electric motor Class 10?

The electric motor works on the principle that when a coil is placed in the magnetic field and the current passes through it resulting in rotation of the coil.

## What is electric motor and its principle?

The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.

No matter the type of motor, there are three basic parts: a stator, a commutator, and a rotor. Together they use electromagnetism to cause the motor to spin.

## What is the role of commutator in electric motor?

The commutator assures that the current from the generator always flows in one direction. … On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils.

## What is the motor principle?

The principle of the electric motor is that it converts electrical energy into kinetic energy (mechanical energy) through the interaction of the two magnetic fields.

## What is basic motor principle?

The basic working principle of a DC motor is: “whenever a current carrying conductor is placed in a magnetic field, it experiences a mechanical force”. … Otherwise, the direction of force would have reversed every time when the direction of movement of conductor is reversed in the magnetic field.

## What is Motor and its types?

A synchronous motor is a doubly excited machine, meaning it includes two electrical inputs. In a common three-phase synchronous motor, one input, usually three-phase AC, supplies the stator winding to produce three-phase, rotating magnetic flux. The rotor supply is usually DC, which excites or starts the rotor.
