In a three-phase induction motor, the stator windings will produce a rotating magnetic field, because the three phases move 120 degrees apart from each other.
Current will be generated in the conductors embedded in the rotor, due to the cutting of the rotating magnetic field and will produce the necessary torque for its rotation.
When three-phase power is supplied, the rotating magnetic field is created, and the rotor follows it due to the torque produced.
When the rotor reaches the speed of the rotating magnetic field, i.e. the synchronous speed, the conductors in it will reduce the cutting of the rotating magnetic field, thus slowing down due to the lack of torque.
So you'll realize now, the rotor speed will never reach its synchronous speed, and it is always a little behind the synchronous speed.
Induction motors are also referred to as asynchronous motors, due to this.
This speed difference related to its synchronous speed, is given as the "fractional slip" of the motor.
