1. A turbomachine comprising:
a rotating group with a wheel supported on a shaft;
a housing that houses the wheel for rotation therein about an axis of rotation;
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; and
a controller configured for control of the e-machine, the controller including a bus bar member that includes a bus bar that is partly covered over by an electrically-insulative covering member, the covering member having a first side and a second side that faces opposite the first side, the bus bar including a thermal pad and an electrical connector that extends from the thermal pad and that projects from the first side, the thermal pad having a thermal terminal surface that is exposed from the second side of the covering member, the controller including a heat sink member facing the second side, the thermal terminal surface being thermally connected to the heat sink member with the heat sink member configured to receive heat from the bus bar member.
