INTEGRATED E-MACHINE CONTROLLER FOR TURBOMACHINE WITH THERMALLY DE-COUPLED FASTENER ARRANGEMENT

A turbomachine (1100) includes a housing (1118) and a rotating group that is supported for rotation about an axis of rotation (1104) 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 (1114) 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 (1150) 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 (1158) that attaches the integrated controller to the e-machine housing. The fastener arrangement thermally decouples the integrated controller from the turbomachine stage.
