  • Publication number: 20230137765
    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.

  • Publication number: 20220337107
    Abstract: A rotor for an electric motor, having a laminated rotor core which is rotatable about a rotation axis and has a plurality of rotor laminations which are arranged axially next to one another, at least one magnet which is held in a magnet cutout in the rotor lamination and has a first side face which extends at least along a first side length and a second side face that is oriented at an angle to the first side face and extends at least along a second side length and which is connected by an adhesive to a boundary face of the magnet cutout. An electric motor having a rotor, and a method for seeming a magnet in a rotor are also provided.

  • Publication number: 20220337138
    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). The disc element (16) is mounted on the rotor shaft (14) by a jointing process and the main body(ies) (20) are mounted on the rotor shaft (14) by a jointing process and only after the corresponding main body (20) is mounted is the associated permanent magnet (26) arranged and glued into the at least one cavity (24).

  • Publication number: 20220247260
    Abstract: An electrical machine (10) for an electrically operable axle of a motor vehicle, having a shaft (12) with an axis of rotation (D), at least one bearing (14), wherein the shaft is rotatably mounted via the at least one bearing, at least one end shield (16), and at least one bearing ring (18), which is arranged coaxially with the axis of rotation (D). The at least one bearing is connected to the end shield via the bearing ring, and the bearing ring has at least one longitudinal recess (20a, 20b) on the outside for fluid evacuation. An electrically operated axle for a motor vehicle having the electrical machine is also provided.

  • Publication number: 20220216754
    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.
