What is the principle of electric motor and generator?

Contents

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 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.

What is a generator and a motor?

Motors and generators are electromagnetic devices. They have current-carrying loops that rotate in magnetic fields. … Electric motors convert electrical energy into mechanical energy, while electric generators convert mechanical energy into electrical energy.

What is an electric motor explain with diagram?

Electric motor: A motor is a device which converts electrical energy into mechanical energy. 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.

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 working principle of synchronous generator?

The synchronous generator works on the principle of Faraday laws of electromagnetic induction. Electromagnetic induction states that electromotive force induced in the armature coil if it is rotating in the uniform magnetic field. The EMF will also be generated if the field rotates and the conductor becomes stationary.

What are the types of generator?

There are three main types of generators: portable, inverter and standby.

What type of motor can be used as a generator?

any motor can be used as a generator and any generator will motor under the proper Circumstances. The purpose of this paper is to describe the connections required to convert the two most common types of induction motors into AC generators.

Can electric motor act as generator?

In principle, any electrical generator can also serve as an electric motor, or vice versa. In hybrid vehicles and other lightweight power systems, a “motor–generator” is a single electric machine that can be used as an electric motor or a generator, converting between electrical power and mechanical power.

Can any motor be 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.

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.

Why are electric motors important?

Electric motors impact almost every aspect of modern living. Refrigerators, vacuum cleaners, air conditioners, fans, computer hard drives, automatic car windows, and multitudes of other appliances and devices all use electric motors to convert electrical energy into useful mechanical energy.

What are the parts of electric motor?

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.
