In a synchronous motor damper windings are provided on
Stator frame
Rotor shaft
Poles faces
None of the above
Poles faces
Damper windings in a synchronous motor are provided on the poles faces. These windings serve the essential function of enhancing the motor's performance during transient conditions.

P=602╧АNтАЛ тАФ The power output of rotating machinery
T=P/╧Й тАФ The relationship of torque and power
The damper windings provide additional torque to the rotor by generating a magnetic field that opposes changes in rotor speed. This helps in smoothing out fluctuations in torque and stabilizing the rotor position during sudden load changes.
Damper windings stabilize synchronous motor operation.
They help control rotor position during transient states.
Enhances stability during load variations
Improves performance during start-up conditions
Increases manufacturing complexity
May require additional cooling methods
Used in large industrial motors
Common in synchronous generator systems
The damper winding assists in maintaining synchronous operation even if the rotor experiences sudden speed changes.
Option A is incorrect as the stator frame does not directly hold damper windings.
C is correct тАФ Damper windings are essential for stabilizing torque in synchronous motors during transient conditions.
In exams, remember that components affecting stability are crucial in synchronous machines.
