A turbomachine includes a rotating group with a wheel supported on a shaft. The turbomachine includes a housing that houses the wheel for rotation therein about an axis of rotation. The turbomachine includes an e-machine section with an e-machine operatively connected to the shaft and configured to convert energy between the e-machine and the shaft as the shaft rotates. Furthermore, the turbomachine includes a controller configured for control of the e-machine. The controller has a bus bar member that includes a bus bar that is partly covered over by an electrically-insulative covering member. The bus bar includes a thermal terminal surface that is exposed from the covering member. The controller includes a heat sink member, wherein the thermal terminal surface is thermally connected to the heat sink member with the heat sink member configured to receive heat from the bus bar member.

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.

Integrated e-machine controller for turbomachine having fastening arrangement

A controller for an e-machine of a turbomachine including a support structure, a printed circuit board, and a fastener arrangement that retains the printed circuit board on the support structure, the fastener arrangement including a resilient member that resiliently biases the printed circuit board towards the support structure.

Resilient printed circuit board retention arrangement

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.

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.

Coolant system for integrated e-machine controller for turbomachine

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.
