Abstract: An electric motor for a motor vehicle, in particular for a braking or steering system, comprising a motor housing with a housing cover, and a stator inserted in the motor housing comprising a ring-shaped switching unit, which is arranged on a front side facing the housing cover, wherein at least one spacer element axially protruding in the direction of the housing cover is arranged on the switching unit, wherein the spacer element is designed to be elastic at least in the radial direction and/or the tangential direction.

Abstract: An electric motor of a motor vehicle, in particular an auxiliary unit, with a stator having a stator winding as well as with a rotor as well as with a switching unit and with a contact adapter for an electric motor connection. The stator and the rotor are arranged concentrically to a motor axis in a motor housing, which is closed with a bearing plate arranged perpendicular to the motor axis. The switching unit is placed on the stator and electrically contacted by the stator winding, and the contact adapter is connected to the switching unit and in electrical contact with it. A plug connection of the contact adapter is arranged in an opening of the bearing plate. A method for the mounting of an electric motor as well as an auxiliary unit of a motor vehicle are also provided.

Abstract: An electric motor of an ancillary unit of a motor vehicle, in particular an electromechanical brake booster, contains a sensor carrier which is manufactured from a plastic and has a body to which a sensor is mounted. A plurality of contact pins are embedded in press-fit technology in the body, which are guided through in each case a corresponding fastening hole of the sensor. Furthermore, a motor vehicle has such an ancillary unit with the electric motor.

Abstract: An electric motor of an auxiliary unit of a motor vehicle, in particular an electromechanical brake booster, contains a bearing shield and a sensor carrier manufactured from a plastic. The sensor carrier has a body arranged perpendicularly to an axis of rotation, to which a sensor is mounted and to which arms extending at least partly parallel to the axis of rotation are connected on the edge side. The arms are fastened to the bearing shield.

Abstract: An electric motor of an ancillary or auxiliary unit of a motor vehicle, in particular an electromechanical brake booster, includes a stator disposed concentrically to a rotor axis. The stator includes a plurality of electric coils wired for a plurality of phases. A one-piece or integral bus bar electrically contacts each phase and protrudes through a passage opening of a bearing shield. The busbars are at least partially encased or surrounded by a common plastic material overmolding or encapsulation. An ancillary or auxiliary unit of a motor vehicle is also provided.

Abstract: An electric motor of an ancillary unit or an auxiliary assembly of a motor vehicle, in particular an electromechanical brake booster, includes a rotor shaft which is disposed along a rotor axis. The rotor shaft includes a cylindrical main portion, which has a round cross-section perpendicular to the rotor axis, and an assembly portion, which adjoins the main portion and has a barrel-shaped cross-section perpendicular to the rotor axis.

Abstract: A stator of an electric motor has stator teeth that carry coils of a multi-phase stator winding. A connection element has insert pockets with contact elements inserted therein each with at least one insulation displacement contact as a connection point for a wire portion of coils joined to one another. A contact apparatus is mounted on the connection element and has a contact housing with a connection socket with phase plug connectors corresponding to the number of phases. The contact apparatus has busbars which correspond to the number of phases and which each have a first and a second bar end. The first bar ends are flexibly or movably in contact with one of the phase plug connectors each and the second bar ends are each inserted or can each be inserted in a contact slot of one of the contact elements to form a terminal connection.
