Abstract
A method of cooling a set of rotor winding end turns of a rotor assembly can include directing a fluid coolant flow to a coil support assembly, delivering the fluid coolant flow, by a first coolant distribution ring of the coil support assembly, radially outward toward rotor winding end turns; and delivering the fluid coolant flow, by a coil support disc of the coil support assembly, axially outward toward the rotor winding end turns. The method can further include expelling fluid coolant flow by a second coolant distribution ring radially outward toward a set of stator windings, and expelling, by the coil support disc, the fluid coolant flow axially outward toward the rotor core.
