An electric motor including a rotor rotatably mounted about a rotational axis extending in the axial direction, and a stator including stator teeth widened in a T shape at the tooth-base side to form pole tabs and extending in the circumferential direction. The pole tabs may form a bearing shoulder. A respective stator slot for receiving coils of a stator winding is formed between adjacent stator teeth and a slot opening formed between mutually facing pole tabs. A reinforcing element may be inserted into a slot opening. The reinforcing element are held on mutually facing pole tabs of adjacent stator teeth by the bearing shoulders. The reinforcing element includes a contour that engages a bearing region to reduce a contact area with the bearing shoulders.
