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.

Abstract: A permanent magnet machine includes a machine housing having an inner surface that extends between a first housing end and a second housing end along a central longitudinal axis. The permanent magnet machine also includes a stator disposed within the machine housing, the stator having a stator core having an exterior surface extending between a first face and a second face along the central longitudinal axis, wherein the exterior surface defines a discontinuous region that is arranged to minimize points of contact between the inner surface and the exterior surface. The discontinuous region is at least partially defined by at least one of a first perturbation and a second perturbation that is circumferentially spaced apart from the first perturbation.

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.
