# Best answer: What is the principle of electric motor and generator?

Contents

Electric generator follows Fleming’s right-hand rule. The working principle of a motor is based on the current-carrying conductor that experiences a force when it is kept in the magnetic field. The working principle of generator is based on electromagnetic induction.

## What is the principle of an electric motor?

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.

## What is the principle of electric generator Class 10?

Principle: An electric generator works on the principle of electromagnetic induction. When a coil is rotated between the magnet or when the magnet is rotated in and out of the coil the current is induced in the coil and the direction of current is given by Fleming’s right hand rule.

## What are similarities and dissimilarities between a motor and electric generator?

The motor and the generator are almost similar from the construction point of view, as both have stator and rotor. The main difference between the two is that the Motor is an electric device which converts electrical energy into mechanical energy. The generator is vice versa of that motor.

## What is an electric motor explain with diagram?

An electric motor is a device that converts electrical energy into mechanical energy. Diagram: Electric motor. Working of an electric motor: An electric motor works on the principle of magnetic effect of electric current. In an electric motor, a rectangular coil ABCD in placed between two magnets in poles N and S.

## How an electric motor works step by step?

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.

## What is the principle of generator?

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. The conductor coil along with its core is known as an armature.15 мая 2019 г.

## What is the principle of an AC generator?

AC generators work on the principle of Faraday’s law of electromagnetic induction which states that electromotive force -EMF or voltage – is generated in a current-carrying conductor that cuts a uniform magnetic field.

## What is mean by electric generator?

In electricity generation, a generator is a device that converts motive power (mechanical energy) into electrical power for use in an external circuit. … Generators provide nearly all of the power for electric power grids.

## Can an electric motor be used as a generator?

You can use just about any motor to generate electric current, if it is wired correctly and you follow specific rules for its use. Modern AC induction motors are quite simple to wire as alternating current generators, and most will begin generating electricity the first time you use them.

## Why commutator is used in electric motor?

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.

## Why are electric motors important?

More than 40% of generated electricity is consumed by industry, and two-thirds of that energy is used by electric motors. By using more efficient motors it would be possible to achieve huge savings in both energy and carbon dioxide emissions.

## What are the parts of electric motor?

Motor Components

The components of an electric motor may include a rotor, thin sheets of stacked metal called laminations, a stator, wire windings, magnets, a commutator, brushes, poles, electrical interconnects and a housing.
