The rotor of a three phase induction motor rotates in the same direction as the rotating field produced by the stator flux

The current carrying rotor conductors are placed in the magnetic field produced by stator.

Consequently, mechanical force acts on the rotor conductor produces a torque which tends to move the rotor in same direction as the rotating field.

The stator of an induction motor consists of a number of overlapping windings offset by an electrical angle of 120°. When the primary winding or stator is connected to a three-phase alternating current supply, it establishes a rotating magnetic field which rotates at a synchronous speed.
If the phase sequence is R,Y,B, the Y phase current lags the R phase current by 120 degree and B phase current lags the Y phase current by 120 degree or leads the R phase current by 120 degree.The phase current Ir, Iy and Ib set up flux in the core. The resultant magnitude of the average flux can be calculated by adding the magnetic flux produced by individual current.
