# What is the principle construction and working of electric motor?

Contents

Hint:Electric motor uses the principle of magnetic force on a current carrying conductor. The direction of force depends on the direction of current flow and magnetic field. However, we can fix the magnetic field and create torque on a loop depending on the current flow. That is how electric motors are constructed.

## What is the principle behind the working of an electric motor explain its construction and working with the help of a well labeled diagram?

Principle of motor : A motor 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. When electric current is passed into the rectangular coil, this current produces a magnetic field around the coil.

## What are the advantages of electric motor?

Electrical motors are more environmentally-friendly, as they do not cause pollution by burning fossil fuels, which in turn produces harmful greenhouse gases. Electrical motors generally save the end-user money over time, while gasoline engines are more expensive in comparison.

## 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 the working of motor?

Electric motors involve rotating coils of wire which are driven by the magnetic force exerted by a magnetic field on an electric current. They transform electrical energy into mechanical energy.

## What is the principle of an electric?

Electricity, simply put, is the flow of electric current along a conductor. This electric current takes the form of free electrons that transfer from one atom to the next. Thus, the more free electrons a material has, the better it conducts.

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

Motor Basics

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. As long as the motor receives steady current, the motor works.
