A steering actuator including a motor having a rotor including opposing input and output ends. A driven gear is supported on the input end of the rotor shaft for rotation with the rotor shaft and the output end provides a rotational output of the steering actuator. An override shaft is supported for rotation parallel to the rotor and a drive gear is supported for rotation with the override shaft wherein the drive gear is longitudinally movable relative to the driven gear to engage and disengage the drive gear relative to the driven gear. A coupling structure is provided on an end of the override shaft for detachable engagement with an auxiliary driver. The auxiliary driver provides a rotational driving force to the override shaft for effecting rotation of the rotor shaft.

Manual override for steering actuator

A permanently magnetizable rotor having a central rotor structure including a rotor shaft supporting a cylindrical backiron. The rotor further includes a multi-pole structure comprising circumferentially alternating pole elements, and a rotor cover extending longitudinally over the multi-pole structure. The rotor additionally includes an endcap including an engagement surface positioned in engagement with an end of the backiron. The endcap defines first and second anti-rotation features for preventing circumferential rotation of one or more of the pole elements about the backiron. The first anti-rotation feature is configured differently than the second anti-rotation feature and each anti-rotation feature defines a torque transmitting feature for transmitting a torque from different locations on the multi-pole structure.

Rotor including anti-rotation feature for multi-pole structure

A retention structure for retaining a heat generating component to a heat dissipating substrate. The heat generating component has a heat transfer surface and an opposing biasing surface, and the heat dissipating substrate has opposing first and second sides. The retention structure has a generally U-shaped retention body including an elongated base having opposing ends, and legs extending from the ends of the base. Each of the legs includes a positioning slot. The substrate includes a pair of passages for receiving the legs therethrough, and a pin structure is positioned on the substrate and extends through the positioning slots in the legs to locate the base of the retention body adjacent to the biasing surface and effect a biasing of the heat transfer surface toward the substrate.

Retention structure for heat generating component

An electric motor assembly including a stator assembly and a rotor assembly extending through the stator assembly. A first end cap is located adjacent to a first end of the stator assembly and includes a bearing insert supporting a first end bearing for receiving an end of a rotor shaft. A second end cap is located adjacent to a second end of the stator assembly. An endbell is formed separately from the second end cap and is positioned within the second end cap. The endbell supports a bearing for a second end of the rotor shaft. An overmold material extends through the stator assembly. The overmold material may form the first end cap, supporting the bearing insert therein, and extends within and substantially fills an annular space within the second end cap.

Frameless electric motor assembly

A sense magnet assembly including a generally circular hub portion defining a central axis. The hub portion includes a generally disk-shaped base portion and an outer wall extending axially from an outer edge of the base portion. An elastic magnet material is provided including a plurality of annular portions positioned at radially spaced locations. A substantially rigid annular divider formed of a non-magnetic material is located between adjacent pairs of the annular portions of the magnet material, and a rigid cover is provided extending over the magnet material to limit movement of the magnet material in response to centrifugal forces.

Sense magnet assembly including multiple annular portions with alternating magnetic poles

A multi-track sense magnet for use in a system for sensing the relative displacement of two elements, and including a magnetic structure that is moveable relative to detector devices for detecting movement of the magnetic structure. The magnetic structure includes at least a first track and a second track extending generally parallel to each other, each track including a plurality of sectors of alternating magnetic poles. A blocker track is located between the first and second tracks, wherein the blocker track includes a predetermined number of sectors corresponding to the number of sectors on the first track. Each sector of the blocker track is aligned with and defines an opposite magnetic pole to an adjacent sector of the first track to alter the magnetic field of the first track extending toward the second track.
