Zusammenfassung: | A method (200) of cooling a set of rotor winding end turns (112) of a rotor assembly (96) can include directing a fluid coolant flow (85) to a coil support assembly (140), delivering the fluid coolant flow (85), by a first coolant distribution ring (141) of the coil support assembly (140), radially outward toward rotor winding end turns (112); and delivering the fluid coolant flow (85), by a coil support disc (144) of the coil support assembly (140), axially outward toward the rotor winding end turns (112). The method can further include expelling fluid coolant flow (85) by a second coolant distribution ring (142) radially outward toward a set of stator windings (90), and expelling, by the coil support disc (144), the fluid coolant flow (85) axially outward toward the rotor core (100). |
