What is the working of 3 phase induction motor?

What is the working of induction motor?

Working Principle of Induction Motor

The motor which works on the principle of electromagnetic induction is known as the induction motor. The electromagnetic induction is the phenomenon in which the electromotive force induces across the electrical conductor when it is placed in a rotating magnetic field.

Why are three-phase motor used?

Businesses use three-phase power because they can carry a heavier energy load while also efficiently distributing it. Three-phase motors also don’t require an additional starter like a single-phase motor. This means the energy provided by a three-phase motor is sufficient enough to start by itself.

Is a 3-phase induction motor self starting?

Three-phase induction motor is self-starting, because winding displacement is 120 degrees for each phase and supply also has 120 phase shift for 3-phase. It results in a unidirectional rotating magnetic field is developed in air gap which causes 3-phase induction motor to self-start.

Why is it called induction motor?

This type of engine is also known as an induction motor. The asynchronous motor is based on the currents induced in the rotor from the rotating magnetic field of the stator. That’s why it’s called an induction machine.
