Abstract

See full text

An electric motor with a stator and an axle (20). The stator has a laminated stator core (10) formed from a multitude of individual teeth (11). At least some of the individual teeth (11) each have a radially inner pressing portion (13) for elastic and/or plastic deformation and establishment of a press-fit connection between the laminated stator core (10) and the axle (20). The stator is fixed to the axle (20) through the deformation of the pressing portions (13) and a force acting on the axle (20). At least one securing element (30) is on at least some of the pressing portions (13) to transmit a torque between the axle (20) and the laminated stator core (10) and fix the position of the laminated stator core (10) relative to the axle (20) in the circumferential direction (U).
