1. An end support for a rotor assembly, comprising:
a bottom bracket support configured to at least partially, underlie an end turn of a set of rotor windings, relative to a rotational axis of the rotor assembly, and defining a first cavity underlying the end turn;
a top bracket support configured to at least partially, overlie the end turn, and defining a second cavity overlying the end turn, the top bracket support defining a collection surface; and
passages extending radially through the end turn and fluidly coupling the first cavity and the second cavity;
wherein the bottom bracket support and top bracket support are coupled such that coolant received by the first cavity is radially expelled through the passages in the end turn into the second cavity, where the coolant is collected and redirected by the collection surface.
