ABSTRACT:
A rotor comprising stacked laminations having conductor slots and axial passageways provided with closed-slot spacer assemblies that are stacked in groups between selected axially spaced rotor laminations to hold said laminations apart while sealing the conductor slots thereby to form radial cooling ducts through the laminations of the selected axially spaced groups and around the closed-slot spacer assemblies. According to the method of the invention, the spacer assemblies are secured in selected operating position by being staked to certain of the main rotor laminations, and a characteristic staking procedure is used to secure individual plates of each of the assemblies together.
