A method of and an apparatus for manufacturing a housing is disclosed. The housing to be manufactured has a sleeve-shaped housing wall extending about a longitudinal axis of the housing and a cover disposed inside the housing wall transverse to the longitudinal axis at a predetermined position between longitudinal ends of the housing wall. The method comprises providing a precursor of the housing, in which the cover is formed integrally with the housing wall and is arranged at one of the longitudinal ends of the housing wall, further separating the cover from the housing wall and displacing the cover relative to the housing wall in the direction of the longitudinal axis from the one longitudinal end into the predetermined position.

A non-drive end housing element for an electric drive assembly of a includes a bell which includes a back wall and an outer skirt which is intended to house one end of the electric machine and which includes a flange equipped with a first sealing gasket. The back wall includes an opening intended to be traversed by the rotor shaft and which opens in a recess to receive an angular position sensor. The recess is arranged on a second side of the non-drive end housing element, opposite to the first side, and includes a recess edge equipped with a second sealing gasket. The back wall further includes a hole intended to be traversed by an electrical connection assembly for connecting the electric machine to an electric machine control module. The non-drive end housing element includes a projecting ledge which surrounds the hole and is equipped with a third sealing gasket.

Various embodiments include a rotor for an electric machine comprising: a laminated rotor core; a filler body comprising an aluminum die-cast alloy cast onto the laminated rotor core; a first shaft journal having an air inlet opening; a second shaft journal having an air outlet opening; and a ventilation unit. The filler body connects the laminated rotor core rotationally conjointly to the shaft journals. The laminated rotor core includes a central axial bore partially filled by the filler body forming an axial cooling channel for cooling air within the central axial bore. The shaft journals drive the ventilation unit. Rotation of the ventilation unit draws an air stream in via the air inlet opening, conveys said air stream through the axial cooling channel, and discharges said air stream via the air outlet opening.

An electromotor and a laundry machine are provided. The electromotor has a controller and a controller cover. The controller is arranged on the controller cover. A first end cover and a second end cover of the electromotor are fixedly arranged on two opposite sides of a stator respectively. The controller cover is provided with a first mounting part and a second mounting part secured with a water container. The first end cover or the stator is provided with a third mounting part secured with the first mounting part. The third mounting part is arranged on the first end cover or the stator. The laundry machine has the electromotor.

A vehicle seat actuator includes an electric motor and a gear set that connects the drive motor to the seat and transmits the output of the motor to the vehicle seat. The drive motor and gear set are each disposed in an individual, dedicated housing component. The individual housing components are then assembled together to provide the actuator. The housing components are maintained in the assembled configuration using snap fit mechanical fasteners. Each snap-fit fastener includes a receiving portion provided on one housing component and an insertion portion provided on the other housing component. The receiving portion may be a slot formed in the gear housing that is partially obstructed by an elastic member, while insertion portion is an ear that protrudes from an outer surface of the drive motor housing and forms both a snap-fit engagement with the elastic member and a press-fit engagement with the slot.

A motor assembly includes a motor with a rotor rotatable about a motor shaft and a stator located radially outside the rotor, an inverter to supply power to the motor, a housing provided with a motor housing space that houses the motor and an inverter housing space that houses the inverter, and a first bus bar that electrically connects the motor and the inverter. The housing includes a partition wall portion that partitions the motor housing space and the inverter housing space and is provided with a through hole penetrating in the axial direction. The first bus bar is connected to a coil wire extending from the stator at an end on one side in the axial direction of the stator in the motor housing space, and extends to the inverter housing space through the through hole.

An electric motor built for exposure to high pressure fluid includes a unitary metal sleeve that provides a fluid barrier between the rotor and the stator. An overmolded resin encapsulates the stator windings and reinforces the sleeve to minimize deformation of the sleeve under high fluid pressures. The overmolded resin also fixes the positions of insulation displacement connectors connected to the stator windings, thereby avoiding mechanical brackets and fasteners for holding the insulation displacement connectors in position.

A stator and a stator housing for an electric machine is disclosed. The stator housing comprises an opening to receive the stator in a direction extending along a longitudinal axis of the electric machine to enable the stator housing to be shrink-fitted to the stator. The shape of the opening in the stator housing lying in a cross-sectional plane perpendicular to the longitudinal axis comprises four quarter circle arcs, with at least two of the quarter circle arcs being separated by a non-zero distance, the stator having a corresponding shape to the stator housing.

An electric machine including a rotor shaft having an inner shaft core with a first composition and an outer shaft portion surrounding at least some of the inner shaft core. The outer shaft portion is fabricated from a material having a different composition than the inner shaft core. For example, the inner shaft core could be fabricated from a material having high thermal conductivity, such as copper, while the outer shaft portion is fabricated from a material with lesser thermal conductivity, but greater strength, for example steel. The two-material shaft with a highly thermally conductive core serves to conduct heat from the interior of the electric machine to the housing, or to an exterior apparatus or structure.
