  • Patent number: 11296564
    Abstract: A rotor of an electric machine, in particular an electric motor, having a rotor body, which circumferentially surrounds a shaft and includes a first sub-body and a second sub-body. The first sub-body and the second sub-body are joined together in the axial direction by means of an axle which extends in the axial direction and is offset radially to the outside with respect to the shaft. The first sub-body includes an eyelet, within which a socket receiving the axle is arranged, and the second sub-body includes a lug, which receives the axle. An electric machine, in particular an electric motor, is also provided.
    Type: Grant

  • Patent number: 9312736
    Abstract: An electric machine has in a machine housing, a stator and a rotor which is arranged on a motor shaft which is supported on a non-drive side in a bearing unit which has a ball bearing arrangement and is arranged within the machine housing in a radially elastic and axially displaceable manner. The electric machine is preferably coupled on the drive side without a bearing via a rigid shaft coupling to a work machine, in particular to a hydraulic pump.

  • Publication number: 20140139061
    Abstract: An electric machine, in particular an electric motor, has a one-piece can disposed between a stator and a rotor. The can has a tubular casing, which is loaded with external pressure by a coolant in a machine housing and which is made of fiber composite material. The casing thickness of the can lies between 2.5 mm and 0.5 mm. The can is axially fitted onto a sleeve and the sleeve is mounted to a collar of an end plate of the machine housing. The sleeve has a first axial section projecting into the can and a second axial section aligned with the can.

  • Publication number: 20130257201
    Abstract: An electric machine with a machine housing for accommodating a stator and a rotor with stator and/or rotor windings, which are connected to connecting lines for producing an electrical contact connection. An isolating plate, which covers a line channel for accommodating the connecting lines, has a number of insulating bushes, into which connecting pins are inserted which can be brought into contact with the connecting lines. In this case, the connecting pins with respect to the insulating bushes and preferably the insulating bushes are inserted into the isolating plate in position-coded or angle-coded fashion with respect to the isolating plate.

  • Publication number: 20070081353
    Abstract: Lighting unit, preferably rear light, for vehicles, preferably motor vehicles The lighting unit has a housing (1), in which at least one lamp (2, 3) is housed, which lies behind a lens (4). Furthermore, the lighting unit has at least one electroluminescent layer (12 through 15). In order that the lighting unit may be produced cost-effectively in such a way that a desired, particularly homogeneous light distribution is reliably achieved, the electroluminescent layer (12 through 15) is provided on the lens (4). The components (5, 6) required for the lamps (2, 3) in the housing (1), such as reflectors, may thus be used without restriction. The electroluminescent layer (12 through 15) may be situated without problems on the lens (4). The lighting unit is preferably a rear light for motor vehicles.
