Abstract:
An electric motor apparatus may include a rotor and a stator. The apparatus may include a main field motor stage having a set of stator armature windings positioned on the stator and a set of main field windings positioned on the rotor, where the set of stator armature windings is configured to receive a main multiphase power signal from an alternating current power bus having a first current that causes a first rotating magnetic flux that rotates relative to the stator, where the set of main field windings is configured to receive a secondary multiphase power signal having a second current that causes a second rotating magnetic flux that rotates relative to the rotor, and where a combination of the first rotating magnetic flux and the second rotating magnetic flux causes the rotor to turn at a predetermined reference frequency.

Claim (Index 1):
An electric motor apparatus, comprising:\n a rotor; a stator; a high frequency transformer stage for transmitting an excitation signal from the stator to the rotor, the high frequency transformer stage having a first set of transformer windings positioned on the stator and a second set of transformer windings positioned on the rotor; and a main field motor stage having a set of stator armature windings positioned on the stator and a set of main field windings positioned on the rotor and coupled directly to the second set of transformer windings, wherein the set of stator armature windings is configured to receive a main multiphase power signal from an alternating current power bus having a first current that causes a first rotating magnetic flux that rotates relative to the stator, wherein the set of main field windings is configured to receive a secondary multiphase power signal from the second set of transformer windings, the secondary multiphase power signal having a second current that causes a second rotating magnetic flux that rotates relative to the rotor, wherein a combination of the first rotating magnetic flux and the second rotating magnetic flux causes the rotor to turn at a predetermined reference frequency, and wherein the excitation signal includes a high frequency modulation signal component and a secondary multiphase power component, and wherein an inductance at the second set of transformer windings and the set of main field windings filters the high frequency modulation signal component to form the secondary multiphase power signal.
