Abstract:
1. A striplike lamination for a stator of an electrical machine, comprising: two strip ends, each end having an end tooth and one end contour ( 19 ) on each strip end ( 18 ), wherein the lamination has a straight yoke region ( 12 ), wherein, by means of a shape of the end contour ( 19 ), a difference in length at the lamination ( 10 ) caused by bending of the straight yoke region can be compensated for, wherein the end contour ( 19 ) on each strip end ( 18 ) extends over the straight yoke region ( 12 ) and the end tooth ( 21 ), wherein the end teeth ( 21 ) of the lamination are formed so that the end teeth together comprise one tooth when in a bended, curved state, and wherein the end contour on each strip ( 19 ) forms a concave end contour ( 19 ) which extends over a respective end tooth ( 21 ) and the straight yoke region ( 12 ), wherein the strip like lamination has two identical end contours.
