Abstract
The invention relates to an assembly of an electric machine with at least two abutting circular ring or circular disk-shaped sheet metal layers, wherein each of the sheet metal layers is formed by several circular ring or circular disk-shaped sheet metal segments which are arranged concentrically about a centre axis, of which two each are abutting under the formation of a connecting joint and comprise a predetermined minimum cross-sectional area in the radial direction, and with the sheet metal segments of abutting sheet metal layers partially overlapping one another in the circumferential direction and are joined by welds distributed along the circumferential area, with the number of welds between a connecting joint of two sheet metal segments of a sheet metal layer and a connecting joint of two sheet metal segments of a neighbouring sheet metal layer being calculated in such a manner that the sum of the effective areas of these welds is at least approximately equal to the predetermined minimum cross-sectional area of the sheet metal segments.
