摘要： A mechanically commutated motor (200) configured for use with an external magnetic field (240) is disclosed. The motor (200) includes an axle (208) formed of anon-magnetic material. A rotor (206) is coupled to the axle (208), the rotor (206) including three or more actuator units (205) spaced about the axle (208). Each actuator unit (205) comprises a non-magnetic material, a coil winding (214) along each of the three or more actuator units (205), and a commutator (216) coupled to the axle (208) and electrically associated with the coil windings (214). The motor (200) further includes two or more resilient contacts (210) oriented to direct a current through the commutator (216) to one of the coil windings (214) to induce a current in the coil winding (214) to form an electromagnet that rotates the rotor (206) relative to the external magnetic field (240) from a magnet located external to the mechanically commutated motor (200).

摘要： An electric motor of a motor vehicle, in particular a steering motor, includes a housing having a motor compartment and an electronics compartment. The motor compartment and the electronics compartment are separated by a housing wall that has a plurality of openings. A stator is situated in the motor compartment and an electronics system is situated in the electronics compartment. The stator and the electronics system electrically contact one another through phase connections which project through the openings. A separating element is situated between the stator and the electronics system. The separating element at least partially covers the openings and the housing wall.

摘要： The rotation angle detection device includes: a magnet; a magnetic detection element disposed on the one side in the axial direction relative to the magnet with a gap interposed between the magnetic detection element and the magnet; and a shield. The shield is disposed at a location in the axial direction between a location in the axial direction of a wire member allowing current to flow therethrough and a location in the axial direction of the magnetic detection element, is disposed radially outward of the magnet as seen in the axial direction, and has a portion that overlaps with the wire member as seen in the axial direction. The wire member is disposed at a location in the axial direction that is closer to the magnet than the magnetic detection element is, and is disposed radially outward of the magnet as seen in the axial direction.
