摘要： A rotating rectifier includes diode subassemblies that each have an AC contact between two diodes, held in place by a spring clip or interference fit between an inner DC bus and an outer DC bus. The outer DC bus can also act as a housing and heat sink. Diodes and resistors are distributed around the rotating rectifier. Zener diodes can be included in series with the resistors to provide further protection to the diodes to ensure proper operation of the rectifier.

摘要： A wedge placed between adjacent coils in a generator comprises a wedge body having a generally triangular portion to be positioned at a radially inner location, and a radially outer portion. The radially outer portion includes ends that will be spaced at axial ends of the wedge when the wedge is positioned within a generator. The ends have a first surface spaced a first distance from an apex of the triangle. The end walls extend above the first surface at each of two spaced positions axially inwardly of the ends of the wedge. The end walls are connected to side walls that extend near circumferential edges of the wedge. An open pocket is formed within the wedge body at locations between the side walls and axially between the end walls.

摘要： An example method of reducing loads on a connection shaft includes disengaging a connection shaft from a motor-generator such that the connection shaft is not rotatably coupled to the motor-generator. The method communicates a fluid away from the motor-generator through a communication path established within the connection shaft. An example turbomachine connection shaft is configured to selectively rotatably couple a turbomachine rotor and a motor-generator. The connection shaft establishes a communication path that selectively vents the motor-generator.
