What is the direction of rotation of rotor with respect to the rotating magnetic field?

Rotating Magnetic Field is set up when 3 phase ac supply is provided to the stator windings of the induction motor. Rotating Magentic Field rotates at synchronous speed. Rotor rotates in the direction of the rotating magnetic field

The rotor always lags behind the rotating magnetic field speed(Ns)

In motoring the rotor speed always less than the synchronous speed. The difference in these speeds is called slip.

The direction of synchronous speed and rotor speed is in the same direction.
