Why does a rotor in a three-phase induction motor rotate in the same direction as that of the applied voltage and magnetic flux?

Why does a rotor in a three-phase induction motor rotate in the same direction as that of the applied voltage and magnetic flux?

Answer:

The rotor of a three-phase induction motor rotates in the same direction as that of the applied voltage and magnetic flux due to the principle of electromagnetic induction.

When a three-phase power supply is given to the stator winding, it produces a rotating magnetic field around the conductor in a clockwise direction ¹.

This magnetic field induces a magnetic flux in the rotor bar through electromagnetic induction ¹.

The rotor then receives magnetomotive forces from this flux, which builds up rotating torque and causes the rotor to rotate in the same direction as the magnetic flux ¹.
