Beschreibung
Zusammenfassung:	A method of controlling an electric machine having a separately excitable rotor and stator includes pulsing the electric machine and controlling the electric machine to an OFF state. Pulsing the electric machine includes exiting the rotor with direction current and the stator with a stator biasing current at the same time to generate magnetic flux in the rotor via two separate paths. Pulsing the electric machine may also include terminating the stator basing current when a desired magnetic flux is generated in the rotor. Pulsing the electric machine may include proving a stator flux to the stator such that the electric machine provides a pulse torque.
