    Abstract: A stator defines multiple stator poles with associated electrical windings. A rotor includes multiple rotor poles. The rotor is movable with respect to the stator and defines, together with the stator, a nominal gap between the stator poles and the rotor poles. The rotor poles includes a magnetically permeable pole material. The rotor also includes a series of frequency programmable flux channels (FPFCs). Each FPFC includes a conductive loop surrounding an associated rotor pole. The stator and the rotor are arranged such that the electrical windings in the stator induce an excitement current within at least one of the FPFCs during start-up.

    Abstract: An electric motor has a stator mechanically coupled to the rotor by a nutating traction interface, such that during nutation of the rotor with respect to the stator a tilt axis of the rotor progresses about the axis of rotation of the output shaft. The rotor and a surface of the stator bound a dynamic gap across which a magnetic field is produced by electrical activation of the motor to generate a force between the rotor and the stator. The traction interface and the gap are arranged such that, in a plane containing the axis of rotation of the output shaft, the traction interface is angled with respect to the stator surface bounding the gap. The rotor is connected to the output shaft by a tiltable connection such as a gimbal.

    IPC: H02P25/20

    CPC classification number: H02P25/20

    Abstract: A reconfigurable electric motor (or machine) that may be reconfigured to improve performance given particular motor conditions. The motor is part of a motor system including a stator, a rotor, a microinverter network including a plurality of microinverters, and a motor controller including processing circuitry. The motor controller controls the plurality of microinverters to drive the motor in accordance with a first configuration of a plurality of motor configurations. The motor controller determines, based on determined motor conditions, to reconfigure the motor from the first configuration to a second configuration, where the first configuration has a first pole count that is different than a second pole count of the second configuration. The motor controller further controls the plurality of microinverters to drive the motor in accordance with the second configuration.
