  • Patent number: 12003143
    Abstract: A rotating rectifier associated with an electric machine is provided. In one example aspect, a rotating rectifier includes a diode. The diode can be one diode of a stage of diodes. The rotating rectifier can also include a connection lead, such an exciter connection lead. The connection lead has a diode contact segment in contact with the diode and a first spring segment and a second spring segment positioned on opposite sides of the diode contact segment. The first spring segment and the second spring segment can be positioned adjacent to the diode contact segment. The first spring segment and the second spring segment each have one or more spring laps. The spring laps can be non-planar spring laps, such as undulating spring laps.

  • Patent number: 11984766
    Abstract: A rotor assembly includes a rotor core having a rotatable shaft and defining at least one rotor post, a winding wound around the post that defines an end turn, and a coil support assembly including a coil support disc rotatably coupled to the rotatable shaft and comprising a radially inner portion and a radially outer portion coupled via a set of spokes. The radially outer portion overlies an end turn and defines a set of channels therethrough sized and disposed to receive a flow of fluid from the set of rotor windings.
