Abstract

A dynamo-electric machine includes a self-supporting housing that has a laminated core section and at least one connecting section in the axial extension of the laminated core section. The laminated core section accommodates and secures, and at least sectionally surrounds all sides of, a laminated core of a stator. The individual sheets of the laminated core have a basic outer shape with an especially octagonal cross-section, a stator bore surrounded by radially arranged grooves which are evenly distributed along the circumference of the stator bore, a yoke back that radially adjoins the grooves and extends equidistantly from the stator bore, and axial cavities in the sheet, in regions between the yoke, back and the basic outer shape of the sheets.
