Abstract
Abstract The present invention relates to electric machines and in particular, to gas filled stators of electric machines. The concept of the invention consists in that the stator of the electric machine comprising end pieces and a middle section with a core compressed with bracing ribs and pressure flanges is designed so that the end pieces of the stator are joined to the middle section with the use of the pressure flanges of the stator core.
