<p>A stator part (5) of turbogenerator has a stator active part (17) comprising a ferromagnetic hollow body and a stator conductor (18). A first stator end winding (21') is on a first end of the stator part (5) and a second stator end winding (21'') in on a second end of the stator part, in which the first stator end winding has closed parallel wiring of all the stator conductors (18) and the second stator end winding has open parallel wiring arrangement of all the stator conductors (18). An independent claim is also given for a turbogenerator with a housing containing a stator part.</p>
