1. An electric machine comprising:
a stator defining multiple stator poles with associated stator windings configured to receive a stator current;
a rotor defining multiple fixed rotor poles with associated rotor windings, wherein the rotor defines a field energizable by magnetic fields produced by the stator windings, responsive to the stator windings receiving the stator current; and
a rectification system configured to control against an alternating current being induced in the rotor poles as the field is energized by magnetic fields produced by the stator windings when receiving the stator current.
