"WebDF generators are wound rotor asynchronous machines, with the rotor windings connected to a small converter via slip rings and brushes. The generator feeds power from both the directly connected stator (approx. 2/3 of Pn) and the rotor (approx. 1/3 of Pn). The converter enables the generator’s speed, power and power factor to be controlled. " - Induction generator slip
