Abstract

It is designed for re-charging accumulator battery and for producing electric energy with rectified voltage for movable vehicles or for unmovable devices and/or objects. There is reduced radial dimension at increased output current and prolonged lifetime. Part of the cylindrical stator (3) outside surface is smooth and embraced tightly by enveloping front aluminum housing (11a) with square-oval shape united with the front end bell (11b). To the front enveloping aluminum housing (11a) rear enveloping aluminum housing (14a) with the same square-oval shape frontal is pressed and mirror-image disposed to wards the front enveloping aluminum housing (11a). In the corners of the front enveloping aluminum housing (11a) and the rear enveloping aluminum housing (14a) more than two axial ventilation ducts (12) are formed extending from the front enveloping aluminum housing (11a) in the rear enveloping aluminum housing (14a).
