Abstract:
The invention relates to a stator of an electric machine, comprising:—a laminated stator core (3), which has a stator axis (2), comprises a plurality of stator teeth (5) and a plurality of stator slots (6) formed between the stator teeth (5), and is formed by a plurality of stacked stator laminations (4); and —electrical conductor elements (10), which run through the stator slots (6) of the laminated stator core (3) and are provided in order to form an electrical winding, more particularly a plug-in winding. In each of the stator slots (6), a slot insulator (11), more particularly a slot insulation paper, is provided in order to electrically insulate the conductor elements (10) from the laminated stator core (3). The stator laminations (4) each have a plurality of lamination teeth (7) and a lamination yoke (8), which connects the lamination teeth (7). The stator teeth (5) of the laminated stator core (3) are each formed by stacked lamination teeth (7) of the stator laminations (4). The stator is characterized in that, in the laminated stator core (3), at least one stator lamination (4) is provided which is rotated in peripheral direction with respect to the stator axis (2), relative to other of the stator laminations (4) of the laminated stator core (3), such that, in each stator slot (6) of the laminated stator core (3), a lamination tooth portion (12) of one of the lamination teeth (7) of said stator lamination protrudes into the stator slot (6).
