New and/or alternative approaches to performance control in an engine system having a compressor configured to receive torque from each of a turbine placed in an exhaust output of an engine and an electric motor. A control unit for the electric motor, referred to as an ETurbo controller, is provided with each of a speed control signal and a torque control signal from an engine control unit. The ETurbo controller is configured to use the torque control signal and speed control signal to operate the electric motor without causing the compressor to exceed a speed boundary.

Electric boost device control for turbocharger

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.
