ABSTRACT:
An electrical alternating current machine having a stator sheet metal body defining an external contour of a regular n-sided polygon or a circular sheet metal shape. The radial and axial restraint of the sheet metal pack occurs by means of casing walls, tension rails (23) and end plates. The air is conveyed in the electrically unused casing corners. The sheet metal pack, together with the casing walls and end plates, form a compact self-supporting constructional unit with reduced shaft centerline height for a given power.
