An induction motor always runs at a speed less than synchronous speed because the rotating magnetic field which is produced in the stator will generate flux in the rotor which will make the rotor to rotate, but due to the lagging of flux current in the rotor with flux current in the stator, the rotor will never reach ...

The induction motor can not run at synchronous speed because synchronous speed is a hypothetical speed not a rela speed.
Explanation:
Synchronous speed can not be achieved in real world because to achieve that speed a vacuum is required with friction which is total impossible in real world.
Synchronous speed is the maximum speed which is achieved by the motor without any torque.
Motor can reach near to that speed if there is no load on that motor. It means that the motor is not in working, it is left switch on.
If we put load on the motor, then torque is generated which leads to reduction of speed for useful working of motor
