Abstract: A rotor for an electric machine including a shaft having a first end, a second end, an outer surface and an inner surface that defines a passage extending between the first end and the second end. A plurality of rotor laminations is mounted to the outer surface of the shaft. A plurality of windings extends about the plurality of rotor laminations. The plurality of windings includes a first end turn arranged proximate the first end and a second end turn arranged proximate the second end turn. An end turn support is arranged at one of the first and second end turns. The end turn support includes a cooling circuit fluidically connected to the passage. The cooling circuit includes an outlet that directs coolant onto the one of the first and second end turns.
