What is the principle and working of electric motor?

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 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 the principle on which motor works?

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 working principle of an electric motor explain clearly its construction and working method with appropriate diagram?

Working principle: When a charged particle moves through space, it creates a magnetic field. We can assume electric flow through a conductor to be electrons moving through it. So, a magnetic field will be generated due to the conductor interacting with the magnetic field of the permanent magnet.

What is the principle of an electric motor briefly explain the construction and working of an electric motor using a Labelled diagram?

A power supply – In general, a simple motor has a DC power source. It provides power for the armature of the motor or field coils. Field Magnet (can be a permanent magnet or an electromagnet) – The magnetic field by virtue of Fleming’s left-hand law, helps to produce a torque on the rotating armature coil.

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 electric motor and diagram?

Electrical energy is converted in into mechanical energy in an electric motor. Working of electric motor: As shown in the diagram, when a current is passed through the coil PQRS the coil starts rotating anti clockwise because a downward force acts on length PQ and at the same time an upward force acts on RS.

What is the basic principle of DC motor?

Operating Principle

DC motors operate on Faraday’s principle of electromagnetism which states that a current-carrying conductor experiences a force when placed in a magnetic field.

What is mean by 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 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 are the 6 parts of an electric motor?

These six components include:

  • 1) The Rotor. The rotor is the moving part of your electric motor. …
  • 3) The Bearings. The rotor in your electric motor is supported by bearings, which allow it to turn on its axis. …
  • 4) The Windings. …

What is the role of brushes in electric motor?

IN ELECTRIC MOTOR the function of brushes is to make contact with the rotating rings and through them to supply current to the coil. function of commutator in an electric motor is to reverse the direction of current through the coil periodically.

What are the applications of electric motor?

The applications of electrical motor mainly include blowers, fans, machine tools, pumps, turbines, power tools, alternators, compressors, rolling mills, ships, movers, paper mills.
