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.
