Pole tooth module for an electric machine, active part comprising a pole tooth module, and electric machine

An active part for an electric machine comprising a pole tooth module, the pole tooth module comprising:

• a pole tooth having 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;
• an insulation body enclosing the pole tooth, the insulation body electrically insulating the pole tooth from the coil which is arranged around the pole tooth, the insulation body encloses the pole tooth by way of, a central piece, a first frame element and a second frame element, wherein:
• 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, and
• the second frame element adjoins an opposite side of the central piece, which opposite side faces the pole shoe, and encloses the pole shoe.
