Description

Principle of Electromagnetic Induction:

Electric motors operate based on the principle of electromagnetic induction, discovered by Michael Faraday. When an electric current flows through a wire, it generates a magnetic field around the wire. Conversely, when a wire moves through a magnetic field, it induces an electric current in the wire. This reciprocal relationship between electricity and magnetism forms the basis of electric motor operation.

Components of an Electric Motor:

1. Coil: The coil, typically made of insulated copper wire, is arranged to form a loop or multiple loops within the motor. When an electric current passes through the coil, it generates a magnetic field.

2. Magnets: Permanent magnets or electromagnets create a static magnetic field within the motor. The interaction between this magnetic field and the magnetic field produced by the coil results in a rotational force.

3. Commutator: A commutator is a rotary electrical switch that periodically reverses the current direction between the rotor and the external circuit.

4. Brushes: Brushes are conductive contacts that maintain electrical contact with the commutator, delivering current to the coil as it rotates.

Working Principle:

• When an electric current flows through the coil, it generates a magnetic field that interacts with the static magnetic field produced by the magnets.
• The resulting force causes the coil to rotate.
• As the coil rotates, the commutator ensures that the direction of the current through the coil changes at specific intervals, ensuring continuous rotation in the same direction.

Applications:

• Electric motors are widely used in various applications, including industrial machinery, household appliances, vehicles, and robotics.
• They provide efficient and reliable means of converting electrical energy into mechanical motion, making them indispensable in modern technology.
