D) rotor bars
Synchronous Motor
An AC motor that operates at a constant speed, set by the power supply frequency, and whose rotor is synchronized with the magnetic field of the stator.
Amortisseur Winding
A squirrel-cage winding on the rotor of a synchronous motor used for starting purposes only.
- Understand the functional voltage features of diverse motor types.
- Distinguish between synchronous and induction motors in terms of their operation and characteristics.

Final Answer :
A
Explanation :
The set of squirrel-cage bars on the rotor of a synchronous motor, used to start the motor, is known as the amortisseur winding. This winding helps in providing the necessary starting torque and also serves to dampen oscillations during operation.
