Abstract
A carrier for coils of an electric machine includes a rotation-symmetrical carrier stack having laminations with axial slots which are configured to receive a wire of the coils. Adjacent ones of the slots are separated from one another by a slot wall. The carrier stack has circular end faces and is formed with slot openings for the slots. Electrically insulating material is applied upon at least the slot walls of at least one of the end faces to cover the slot walls at their end face and to electrically insulate the slot walls.
