FIELD: machine building.
SUBSTANCE: dynamo-electric machine includes a self-supporting housing having a polygonal core section and at least one connecting section in axial extension of laminated core section. Polygonal core section accommodates a stator formed from steel sheets laminated in an axial direction, secures and at least on some sections surrounds it with closed side walls on all sides. Individual sheets have a basic outer shape, particularly with an octagonal cross-section. Stator bore is surrounded by radially arranged grooves which are evenly distributed along circumference of stator bore. Steel sheets which form stator core have on their external sides recesses, said recess in form of cooling fins being located on external surface of core section.
EFFECT: improved cooling efficiency and simple design.
