Abstract: A rotor for a separately excited electric machine, including an assembled rotor shaft having a cylindrical hollow shaft body, at the respective axial end of which a shaft stub is arranged, wherein the respective shaft stub has a flange section and a shaft section including an outer shell surface, a slip ring device running through the shaft section, including at least one annular first slip ring which protrudes beyond a distal end of the shaft section in the axial direction of the rotor, and a first busbar connected to the first slip ring and running through the shaft section, wherein one end of the first busbar is guided through a first busbar opening formed in the flange section, and is thus led out of an interior of the hollow shaft body.

Abstract: A pole tooth module for an electric machine is provided. The pole tooth module includes a pole tooth with a pole shoe and a pole head, a coil arranged around a circumferential surface of the pole tooth between the pole shoe and the pole head, and an insulation body enclosing the pole tooth and designed to electrically insulate the pole tooth from the coil. To enclose the pole tooth, the insulation body has a central piece, a first frame element and a second frame element. The central piece is arranged between the coil and the circumferential surface and at least partially surrounds the circumferential surface of the pole tooth. The first frame element adjoins a side of the central piece, which side faces the pole head. The second frame element adjoins an opposite side of the central piece, which opposite side faces the pole shoe, and encloses the pole shoe.
