John C. Kroeger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Motor having multiple independent armature winding sets
    Patent number: 7365504
    Abstract: A motor is provided that includes multiple sets of independent stator windings that are not magnetically coupled, which allows the motor to be driven by multiple independent current drivers, and thereby increases the overall torque generated by the motor. In one embodiment, the motor is a brushless DC motor that includes a rotor and a stator. The rotor is configured for rotation, and the stator surrounds at least a portion of the rotor and has multiple sets of independent stator windings wound thereon. Each set of independent stator windings is configured to be independently energized and, when energized, magnetically independent of the other sets of independent stator windings.
