Final answer:
The nameplate speed of an induction motor is slightly less than the synchronous speed.
Step-by-step explanation:
In an induction motor, the nameplate speed is slightly less than the synchronous speed. The synchronous speed is the speed at which the magnetic field created by the stator rotates in perfect synchronization with the rotating magnetic field created by the rotor. However, due to factors like mechanical losses and slip, the actual speed of the motor is slightly lower than the synchronous speed.
