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 12):
A system comprising:\n a motor control unit including an inverter configured to generate an excitation signal having a high frequency modulation signal component and a secondary multiphase power component; and a motor comprising:\n a rotor; \n a stator; \n a high frequency transformer stage for transmitting the 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 \n a main motor stage having a set of stator armature windings positioned on the stator and a set of main field windings positioned on the rotor, wherein the set of stator armature windings is configured to receive a main multiphase power signal from an alternating current power bus having a current that causes a first rotating magnetic flux that rotates relative to the stator, wherein an inductance between the second set of transformer windings and the set of main field windings filters the high frequency modulation signal component to form a secondary multiphase power signal, and wherein the set of main field windings is configured to receive the secondary multiphase power signal, the secondary multiphase power signal having a 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.
