Abstract
A stator for an electric motor, wherein the stator has a laminated stator core which is formed from a multitude of individual teeth that can be arranged in a ring around an axis of rotation of the electric motor and interconnected in the circumferential direction, wherein each individual tooth of the plurality of individual teeth is flanked on both sides along the circumferential direction by a further individual tooth from among the plurality of individual teeth and has a connection portion for mechanically fixing the individual tooth to the individual teeth by which it is flanked, and wherein at least some of the individual teeth each have a pressing portion for elastic and/or plastic deformation and establishment of a press-fit connection between the laminated stator core and a radially inner axle, so that, upon joining of the stator to the axle, the stator can be fixed to the axle through the deformation of the pressing portions and a force acting on the axle as a result of the deformation between laminated stator core and axle.
