Patent ID: 7208854

Claim:
A generator system comprising: a rotor assembly including a rotor retaining sleeve which surrounds a main rotor core having a multiple of rotor laminations and a main rotor winding bundle, said multiple of rotor laminations stacked generally in a plane normal to an axis of rotation of said rotor assembly; and a coolant system in communication with said rotor assembly, said coolant system communicating a coolant oil between a periphery of said main rotor core and said sleeve, said coolant system communicating said coolant oil through at least one of a multiple of coolant channels generally parallel to said axis of rotation defined along an edge of said multiple of rotor laminations and through a main rotor winding bundle generally parallel to said axis of rotation, said main rotor winding bundle rotationally offset from said multiple of coolant oil channels; a spacer located between at least two layers of said main rotor winding, wherein said spacer is ribbon-shaped and weaved between said at least two layers of said main rotor winding.
