Abstract

Two coil windings per slot are disposed in a dynamoelectric machine rotor. The coil winding conductors are stacked on the sides of the rotor slots with the central coil sides separated by a plurality of insulating spacers driven between them in a radial direction and with the spacers distributed in the axial direction along the rotor slots such that radial ventilating passages are formed by the sides of the spacers and coil conductors.

Coolant gases enter the slots axially below the coils and progress radially through the ventilating passages as well as the slot creepage block and wedge and discharges from the rotor into the stator-rotor air gap.
