Abstract:
1. A stator for an electrical machine, with a stator winding ( 45 ) that is held by a stator core ( 10 ) having first the form of a strip that is then formed into an annular shape, which has grooves ( 14 ) and teeth ( 13 ) on its radially inwardly oriented circumference, whereby the stator core ( 10 ) has a plurality of stacked stator sheet metal lamellae ( 11 ) in the form of strips, the direction of the layers defining an axial direction (a), whereby at least a first stator strip-shaped sheet metal lamella ( 20 ) has a higher flexural strength than second strip-shaped stator sheet metal lamellae ( 21 ), whereby the at least one first stator sheet metal lamella ( 20 ) has a thickness (d LE ) in the axial direction (a) that does not exceed 4 mm, wherein the at least one first stator sheet metal lamella ( 20 ) is located between two end lamellae.
