摘要： 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.

摘要： A rotor for an electric machine, having a plurality of annular laminated core segments, wherein each laminated core segment is made of a plurality of laminations are arranged one behind the other and are adhered together, each laminated core segment has a first end face and a second end face. Each laminated core segment is equipped with at least one magnet pocket, which extends in the longitudinal direction of the laminated core segment, for receiving a permanent magnet, the permanent magnet is introduced into the magnet pocket solely from the first end face. At least two laminated core segments of the rotor are arranged relative to each other such that the respective first end faces of the laminated core segments face one another and are adhered together, and the respective second end faces of the distal laminated core segments are oriented outwards in the longitudinal direction of the rotor.
