Abstract: A fluid compressor device includes a housing and a rotating group supported for rotation within the housing about an axis. The device also includes a controller for an e-machine of a turbomachine having a rotating group that is supported for rotation about an axis including a support structure, a first bus bar that is elongate and that extends about the axis, a second bus bar that is elongate and that extends about the axis, the second bus bar stacked on the first bus bar in an axial direction with respect to the axis, and a fastener arrangement that attaches the first bus bar and the second bus bar to the support structure.

Abstract: A controller for an e-machine of a turbomachine includes a coolant core with a first seat and a second seat thereon. The controller includes a semiconductor circuit component that is seated on the first seat and that is thermally coupled to the coolant core to be cooled thereby. The controller also includes a bus bar that is seated on the second seat and that is thermally coupled to the coolant core to be cooled thereby. The bus bar is thermally coupled to the semiconductor circuit component to receive heat from the semiconductor circuit component and to define a thermal path from the semiconductor circuit component, through the bus bar, and to the coolant core.

Abstract: A fluid compressor device includes an integrated controller of an e-machine. The integrated controller has an arcuate support structure that extends about the axis of rotation of a rotating group. The support structure has a seat that is disposed at a radial area of the arcuate support structure. The integrated controller has an electronics component supported on the seat. The integrated controller includes a retainer clip that is resiliently flexible between a neutral position and a flexed position. The retainer clip is fixed to the support structure and in the flexed position to retain the electronics component on the seat.

Abstract: A fluid compressor device includes a housing and a rotating group supported for rotation within the housing about an axis. The device also includes a compressor stage including a compressor wheel of the rotating group that is supported on a shaft of the rotating group. The device also includes an e-machine stage including an e-machine that is operably coupled to the shaft and that is configured to operate as at least one of a motor and a generator. Additionally, the device includes an integrated controller that extends at least partly over the e-machine stage in a circumferential direction about the axis. The integrated controller includes a coolant core that receives a flow of a coolant therethrough for cooling the integrated controller. The coolant core extends over the e-machine stage in a circumferential direction about the axis.
