Abstract: A stator for an electric machine includes a stator body that is made of a plurality of stator sheets arranged in layers and has a plurality of fluid channels through which a cooling fluid can flow and including an A-bearing shield and a B-bearing shield, each of which is arranged on a respective stator body end face, the end faces lying opposite each other. The A-bearing shield and/or the B-bearing shield and/or the stator body has/have at least one hydraulic connection, by means of which the cooling fluid can be conducted through the A-bearing shield and/or the B-bearing shield and/or the stator body to at least one of the fluid channels.

Abstract: An electric machine for driving a motor vehicle includes a rotor having a central rotor shaft and a laminated core which is made of multiple rotor laminations and is fixed to the rotor shaft. The laminated core is contacted on at least one axial side by an end lamination which produces a tolerance compensation, said end lamination being supported by a securing ring pressed onto the rotor shaft.

Abstract: An electric machine, having a stator and a rotor arranged rotatably in the stator (3), and an end shield arranged non-rotatably with respect to the stator for mounting the rotor therein. The end shield extends at least partially along a radial plane orthogonal to the rotor axis of rotation. The stator is connected to a stator support which extends orthogonal to the axis. The end shield and the stator support have a centering arrangement for centering the end shield with respect to the stator support, which has an annular opening having a radially inner peripheral surface designed as a centering seat, and is abutted by at least three centering studs projecting axially from the end shield. The centering studs are configured to form with the inner peripheral surface the centering arrangement for centering the end shield with respect to the stator support.

Abstract: A rotor has an iron core with rotor laminations which are arranged in at least one stack, plane-parallel to one another. At least one of the rotor laminations is designed as a fluid-conducting lamination and forms at least one flow channel having at least one radial direction component, which flow channel is open on at least one axial side of the fluid-conducting lamination. A rotor lamination is designed as a sealing lamination being arranged on the axially open side of the fluid-conducting lamination, by means of which rotor lamination designed as a sealing lamination the flow channel of the fluid-conducting lamination is sealed substantially fluid-tight on the side of the sealing lamination.

Abstract: A method for producing a rotor (10) for an electric machine, in which the rotor (10) includes a rotor shaft (14), a ferromagnetic main body (20) or a row of ferromagnetic main bodies (20) mounted axially successively on the rotor shaft (14), a disc element (16) mounted on the rotor shaft (14), which connects axially to the main body (20) or one of the main bodies (20), and at least one permanent magnet (26). At least one cavity (24) is formed in the main body(ies) (20), and the magnet (26) is arranged in and glued into the cavity (24).
