Abstract

The electrical machine, in particular a three-phase generator, with a stator winding (12) consisting of winding wire and disposed in the stator core (10) of the machine, has the special feature of the phases (14 to 16) of the stator winding (12) being wound with different slot space factors and the resulting load unbalance being compensated by appropriately cooling the phases.
