Abstract
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.
