How to Evaluate MMF of Damper Winding?

MMF of Damper Winding evaluator uses MMF of Damper Winding = 0.143*Specific Electric Loading*Pole Pitch to evaluate the MMF of Damper Winding, The MMF of damper Winding is when the current flows through the damper winding of the alternator, a flux is produced by the resulting MMF. The MMF (magnetomotive force) of a damper winding is the measure of the magnetic field strength generated by the damper winding in an electrical machine. The damper winding is typically used in synchronous machines, such as synchronous generators or synchronous motors, to dampen oscillations and stabilize the rotor. MMF of Damper Winding is denoted by MMF_d symbol.
