| 摘要 |
The invention relates to an electric machine (EM), comprising a housing (GH) for accommodating a rotor unit (RE), the rotor unit (RE), which can be rotated about an axis of rotation (DA) and which has a rotor shaft (RW) and a first sliding surface (GF1) for producing an electrically conductive sliding contact, a connecting unit (VE) for producing an electrical connection to the rotor unit (RE), which connecting unit comprises a carrier part (TT) made of an electrically conductive material, which carrier part at least partially surrounds the rotor shaft (RW) circumferentially and is rigidly connected to the housing (GH), a contact part (KT) made of an electrically conductive material, which contact part has a second sliding surface (GF2) for producing the electrically conductive sliding contact, a spring part (FT) made of an electrically conductive material, which spring part at least partially surrounds the rotor shaft (RW) circumferentially, is connected to the carrier part (TT) and the contact part (KT) in an electrically conductive and rigid manner, and presses the contact part (KT) against the first sliding surface (GF1) in the direction of the axis of rotation (DA) in such a way that the first sliding surface (GF1) and the second sliding surface (GF2) form the electrically conductive sliding contact. |
