speed and have salient pole rotors. They normally have damper windings in addition
to the field winding. Damper windings consist of bars placed in slots ... currents circulating in the solid
steel or in the damping windings can be treated as currents circulating in two closed
circuits (Kundur, 1994). Accordingly, a three-phase synchronous machi...
