摘要： A rotor and a dynamoelectric machine including a rotor are disclosed. In an embodiment, the rotor includes a rotor body having a plurality of axially extending slots disposed radially about the rotor body, and at least one coil having at least one turn positioned within each of the plurality of axially extending slots. The rotor further includes a plurality of subslots disposed in the rotor body such that each subslot extends axially through the rotor body parallel to an axis of rotation of the rotor body, and is in fluid communication with a radially inner end of a slot; a passageway extending substantially radially outwardly along each axially extending slot for cooling the at least one turn disposed in the slot; and a retaining member in each of the slots for retaining the at least one turn within the slot. Various embodiments provide ventilation via the passageway for cooling the rotor coils.

摘要： The rotor for an electrical machine comprises a plurality of stacked laminations (415). Each lamination (415) includes a plurality of radially extending slots (140) arranged about a circumference thereof and a first chamfer (520) on a surface (550) of each of the slots (140), wherein the surface (550) mates with a wedge (150). The first chamfer (520) connects the surface (550) and a first face (418) of the lamination (415). Advantage: Avoiding electrical contact between laminations due to smearing when the wedge mating surface (550) of the assembled rotor must additionally be machined.
