It is completely possible for the rotor of an induction motor to turn at synchronous speed and still produce turning torque.
Synchronous Speed
The speed at which the magnetic field in an AC motor rotates, dependent on the frequency of the supply current and the number of poles in the motor.
Turning Torque
The torque required to initiate rotation of a body from rest or to maintain rotation at a constant angular velocity.
- Understand the basic principles and functioning of electric induction motors.
- Identify the significance of synchronous and asynchronous speeds within induction motors.

Final Answer :
False
Explanation :
In an induction motor, the rotor must rotate at a speed less than the synchronous speed for the magnetic field to induce a current in the rotor, which in turn produces torque. If the rotor were to reach synchronous speed, no relative motion between the magnetic field and the rotor would exist, thus no induced current and no torque.
