What happens when supply is given to rotor in induction motor?

AC supply will flow supply-frequency currents in rotor winding. This will establish a rotating magnetic field(RMF) at synchronous speed around the rotor. This RMF will induce emf in the stator winding and slip-frequency currents flow in stator windings.

How do you supply power to a rotor?

Like any magnet, the magnetic field produced has a north and a south pole. The normal clockwise direction of the motor that the rotor is powering can be manipulated by using the magnets and magnetic fields installed in the design of the rotor, allowing the motor to run in reverse or counterclockwise.

When I starting an induction motor you have to given supply?

When the supply is connected to the stator of a three-phase induction motor, a rotating magnetic field is produced, and the rotor begins rotating and the induction motor starts. At the time of starting, the motor slip is unity, and the starting current is very large.

What supply is given to the rotor winding of 3-phase induction motor?

In a 3 phase slip ring Induction motor, 3 phase balanced supply is given to rotor winding & stator winding is short circuited .

Which of the following supply is given the rotor winding of 3-phase induction motors?

The stator carries a 3-phase winding (called stator winding) while the rotor carries a short circuited winding (called rotor winding).

What will happen to a 3-phase motor stator winding if 3-phase supply fed into it?

When three-phase stator winding is fed from 3-phase supply, a rotating magnetic field is set up which cuts the rotor conductors. Since the rotor circuit is closed, currents start flowing in the rotor conductors. Now, rotor conductors are carrying currents and are in the magnetic field.

How does the rotor of an induction motor rotate?

The rotor of the induction motor rotates in the same direction as that of the rotating magnetic field. Actually when you give 3 -phase supply to the stator windings, a rotating magnetic field is produced.

What happens when induction motor runs at synchronous speed motor will?

So, theoretically, the Induction motor can never run at synchronous speed. But due to the reduction of speed, again lag influx will be achieved, and the motor will continue to move at this speed due to flux difference between rotor and stator. In short, an induction motor cannot run at induction speed.
