Why no load speed of machine is less than synchronous speed?

Synchronous speed is the rate at which the magnetic field rotates.
If the rotor moved at synchronous speed, then each conductor in the rotor would be moving at the speed of the field. The conductor and the field would appear stationary and not varying with respect to each other.
This means there would be no voltage induced in the rotor conductors. No voltage means no current. No current means no torque.
Without torque there is nothing to keep the rotor turning so it wound start to slow down.
When the rotor is running a bit slower the conductors are now having motion relative to the field and some voltage will be induced in the rotor conductors.
Voltage -> current -> torque -> strength to maintain speed.
i hope it is help you..
