What will be the direction of rotation of the rotor if the primary winding is placed on the rotor of a poly phase induction motor?

The direction of the rotor induces current is opposite to that of the rotating magnetic field. The rotor current induces the flux in the rotor. The direction of the rotor flux is the same as that of the current.

What is the direction of rotation of an induction motor?

The direction of rotation of a 3-phase induction motor is clockwise when it is supplied with 3-phase sinusoidal voltage having phase sequence A-B-C. For counter clockwise rotation of the motor, the phase sequence of the power supply should be.

What determines the direction of rotation for the rotor of a three phase motor?

It’s based on the direction of the rotating magnetic field, which is dependant on the phase rotation. Hence if you swap in two line leads on a three phase motor, the direction of the magnetic field and thus motor will reverse.

What happens if we give supply to rotor instead of stator in srim?

When 3-ϕ supply is given to the rotor instead of the stator and if the stator is short-circuited, then the rotor will start rotating in the opposite direction. If the stator is not circuited, nothing will happen and the rotor will be stationary.

Why should the rotor of the 3 phase induction motor rotate in the same direction as that of its rotating magnetic field?

These current loops create magnetic poles in the rotor iron. The polarity of these rotor poles is such that they are attracted to the poles of the stator’s magnetic field, so they cause the rotor to follow the rotating magnetic field around in the same direction as the rotating magnetic field in the stator.

What is phase sequence how the direction of rotation of a 3 phase induction motor is changed?

We all know that the direction of rotation of a 3-phase motor can be changed by reversing two of its stator leads. This interchanging, if you will, reverses the direction of the rotating magnetic field within the motor.

How do you change the direction of rotation of a 3f squirrel cage induction motor?

The direction of rotation of a 3 phase induction motor can be reversed by interchanging any two of the three motor supply lines. Such that the field rotates counterclockwise rather than clockwise.

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.
