Why is it called damper winding?

Synchronous motors
usually referred to as a damper winding because of its additional property of damping out any oscillation that might be caused by sudden changes in the load on the rotor when in synchronism.

What is the formula of MMF?

Magnetomotive force (mmf), Fm = NI ampere-turns (At), where N = number of conductors (or turns) and I = current in amperes. Since 'turns' has no units, the SI unit of mmf is the ampere, but to avoid any possible confusion 'ampere-turns', (A t).

How to Calculate MMF of Damper Winding?

MMF of Damper Winding calculator uses MMF of Damper Winding = 0.143*Specific Electric Loading*Pole Pitch to calculate 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 MMFd symbol.
