More Information
Summary:The invention relates to an electric machine (1), which includes a stator (3) and a rotor shaft (4) having a cooling device (18), which shaft carries at least one slip ring (7), which has a lateral surface, which electrically contacts a contact element (10) fixed on the stator (3), and which is at least partially accommodated in a recess (8) of the rotor shaft (4), wherein an extension section (11) of the slip ring (7), which is at least partially accommodated in the recess (8), extends beyond the lateral surface (9) in one or both axial directions of the rotor shaft. 本发明涉及一种电机(1)，其包括定子(3)和具有冷却装置(18)的转子轴(4)，该转子轴带有至少一个滑环(7)，所述至少一个滑环具有周面(9)，该周面与紧固在定子(3)上的接触元件(10)电接触，滑环至少部分地被接纳在转子轴(4)的缺口(8)中，其中，滑环(7)的至少部分地接纳在缺口(8)中的延长部段(11)沿转子轴(4)的一个轴向方向或两个轴向方向超出周面(9)延伸。
