    Abstract: An interior permanent magnet motor assembly including a stator and a rotor is provided. The stator includes electromagnetic windings. The rotor is disposed concentrically with the stator about a rotor axis and the rotor has a plurality of rotor segments. The plurality of rotor segments may include a first rotor segment and a second rotor segment. The first rotor segment may have first pockets being arranged to receive at least a first magnet of a first magnet set according to a first rotor topology. The second rotor segment may be axially stacked relative to the first rotor segment about the rotor axis. The second rotor segment may be arranged to receive at least a second magnet of a second magnet set according to a second rotor topology having a configuration that is different than the first rotor topology.

    Abstract: Technical solutions are described for generating an output torque from a multi-winding PMDC motor. An example method includes generating, by a current controller, a first voltage command for a first winding set from a plurality of winding sets of the PMDC motor, the first winding set generates a first current in response to the first voltage command. The method further includes generating, by the current controller, a second voltage command for the second winding set from the winding sets of the PMDC motor, the second winding set generates a second current in response to the second voltage command. The method further includes generating, by the PMDC motor, the output torque based on the first current and the second current.

    Abstract: A brushless motor includes a stator disposed along an axis and a rotor disposed radially inward from the stator. The rotor includes a core, a plurality of first magnets and a plurality of second magnets configured to have opposite poles relative to the plurality of first magnets. The plurality of first and second magnets may each have a substantially rectangular cross-section and are in contact with a substantially flat surface carried by the core that faces radially outward.
