FIELD: electrical engineering; multipole ac electrical machines and their stator and rotor windings.
SUBSTANCE: proposed electrical machine winding has at least most of end-portion conductors made in the form of jumpers whose sectional area at points of connection to bars averaged lengthwise of slot; is smaller than that of winding bars being connected; junctions between mentioned jumpers and bars of winding upper layer are disposed on toothed surface end of core; junctions between these jumpers and bars of winding lower layer are disposed on core yoke end; cross-sectional areas of winding phase lead conductors at junctions between them and bars averaged lengthwise of slot are smaller than those of bars they are connected to.
EFFECT: reduced overhang of end windings, facilitated manufacture, reduced material input.
