Claim 19:
20. An electric machine comprising:
a stator defining multiple stator poles with associated stator windings configured to receive a stator current; and
a rotor defining multiple 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 to produce relative motion between the rotor and the stator, wherein the rotor is maintained in synchronicity with the magnetic fields produced by the stator during operation of the electric machine; and
a controller configured to:
energize the stator windings of the stator by the stator current;
produce a stator magnetic field within the stator by the energized stator windings;
produce a corresponding rotor magnetic field within a ferromagnetic material within the rotor by the stator magnetic field;
generate a force tangential to the rotor by a shift in the stator magnetic field;
move the rotor by the generated force tangential to the rotor;
resist a decay of a magnetic flux within the rotor by current within rotor coils in response to the shift in the stator magnetic field; and
achieve a target operational output of the electric machine.
