Abstract: A rotor (10) is provided for a dynamoelectric machine. The rotor (10) includes a rotor shaft (12) and a laminated core (14). The rotor shaft (12) is adapted to mount the rotor (10) for rotation about an axis (13) of rotation in a dynamoelectric machine. The laminated core (14) includes a shaft receiving opening (42) extending along the axis (13). The opening (42) is defined by a plurality of helical lands (44) separated by a plurality of helical grooves (46), with both the lands (44) and the grooves (46) extending along the shaft (12). The lands (44) are engaged with a shaft (12) to mount the core (14) to the shaft (12) for rotation therewith about the axis (13). The grooves (46) are equally angularly spaced about the axis (13) and extend radially outward from the lands (44) and the shaft (12), whereby rotation of the shaft (12) pumps coolant through the grooves (46) to cool the rotor (10).
