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.

Permanent magnet machine

A permanent magnet machine includes a machine housing and a stator disposed within the machine housing. The machine housing has an inner surface that extends between a first housing end and a second housing end along a central longitudinal axis. The stator has a stator core having an exterior surface and an interior surface, each extending between a first face and a second face along the central longitudinal axis. The stator core defines a plurality of openings that extend from the first face towards the second face.

Permanent magnet machine stator

A permanent magnet machine includes a machine housing and a stator. The machine housing has an inner surface. The stator is disposed within the machine housing. The stator has a stator core having an exterior surface. At least one of the inner surface and the exterior surface defines a discontinuous region that is arranged to minimize points of contact between the inner surface and the exterior surface.

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.

A power steering pump includes, an intake flow channel defined by a first surface; a chamber into which fluid is received; and a plate disposed between the first surface and the chamber. An opening having opposed terminal ends extends through the plate. The intake flow channel is in fluid communication with the chamber through the plate opening and is configured to direct fluid flow through the plate opening into the chamber at a location intermediate and spaced from the terminal ends. The intake flow channel is defined by a bottom surface and a sloped surface extending from the bottom surface toward the plate. The flow channel has a transition zone through which the bottom surface and the sloped surface are joined. The transition zone is located at a position along the intake flow channel at which it and one of the plate opening terminal ends are approximately superposed.

Power steering pump having intake channels with enhanced flow characteristics and/or a pressure balancing fluid communication channel

A vehicular hydraulic system having a hydraulic pump and first and second hydraulic applications arranged in series. A dual relief valve defines first and second flow channels, a passageway and a bypass port. The first flow channel is disposed between the hydraulic pump and the first hydraulic application and the second flow channel is disposed between the first hydraulic application and the second hydraulic application. A first valve member controls fluid flow through the passageway and allows fluid flow from the first to the second flow channel through the passageway when fluid pressure within the first flow channel exceeds a first threshold pressure. A second valve member controls fluid flow through the bypass port and allows fluid flow from the second flow channel to a return line through the bypass port when fluid pressure within the second flow channel exceeds a second threshold pressure.
