First Claim
1. A rotary electric machine assembly comprising:
- a stator;
a shaft including a hollow core;
an inner flanged band including an inner hub supported on said shaft, a first flange and a first containment band;
an outer-flanged band supported on said inner-flanged band including an outer hub, a second flange and a second containment band;
a coolant passage defined between said inner hub and said outer hub; and
a rotor supported on said outer hub between said first and second flanges, said rotor including end portions of windings supported by said first containment band and said second containment band.

Abstract
A rotary electric machine assembly includes a stator and a shaft including a hollow core. Mounted onto the shaft is an inner-flanged band with an inner hub, a first flange and a first containment band. An outer-flanged band includes an outer hub that nests over the inner hub and defines a coolant passage therebetween. The outer-flanged band includes a second flange and a second containment band. A rotor core is disposed within a space between the first and second flanges. Coolant flowing through the coolant passage absorbs heat from the rotor core. The rotor core includes windings having end portions. The first and second containment flanges radially support the end portions of the windings.
