摘要： A stator for an electrical machine is proposed that has a stator winding ( 45 ) that is held by a stator core ( 10 ) that is formed into an annular shape. The stator core ( 10 ) has grooves ( 14 ) and teeth ( 13 ) on its radially inwardly oriented circumference. The stator core ( 10 ) is composed of layered stator sheet metal lamellae ( 11 ), the direction of the layers defining an axial direction (a). It is provided that at least a first stator sheet metal lamella ( 20 ) has a higher flexural strength than second stator sheet metal lamellae ( 21 ), the at least one first stator sheet metal lamella ( 20 ) having a thickness (d LE ) in the axial direction (a) that does not exceed 4 mm.

摘要： Disclosed is a strip-type lamina (10) for the stator (30) of an electric machine comprising a yoke area (12) and several first teeth (18) connected to the yoke area (12) in a single-piece on a first side (14), in addition to first grooves (20) arranged therebetween, and second teeth (22) connected to the yoke area (12) in a single-piece on a second side (16) opposite the first side (14), and second grooves (24) arranged therebetween. The second teeth (22) are arranged in a position of the first teeth (18).

摘要： The invention relates to a strip-type segment (10) for a stator of an electrical machine, said strip-type segment having an end contour (19) on each strip end (18). Said end contours (19) are embodied in such a way that a bending-related length difference on said segment (10) can be compensated.
