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 turbomachine includes a housing and a rotating group that is supported for rotation about an axis of rotation within the housing. The turbomachine also includes a turbomachine stage including a wheel of the rotating group supported within a turbomachine housing of the housing. The turbomachine further includes an e-machine section including an e-machine that is housed within an e-machine housing of the housing. The e-machine is operably coupled to the rotating group and configured to operate as at least one of a motor and a generator. Moreover, the turbomachine includes an integrated controller that extends in a circumferential direction about the axis of rotation. The integrated controller is configured for controlling the e-machine. Additionally, the turbomachine includes a thermally decoupled fastener arrangement that attaches the integrated controller to the e-machine housing. The fastener arrangement thermally decouples the integrated controller from the turbomachine stage.

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.
