Abstract: A turbomachine includes a fluid compressor section with a compressor wheel supported on a shaft and a compressor housing that houses the compressor wheel for rotation therein about an axis of rotation. The turbomachine also 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. The e-machine section includes an e-machine housing that houses at least part of the e-machine. The turbomachine further includes a coolant jacket that is defined at least partly in the e-machine housing. The coolant jacket is configured to receive a fluid coolant flow therein for cooling the e-machine. Also, the turbomachine includes a turbulator insert member that is removably received within the coolant jacket and that sub-divides the coolant jacket for directing the fluid coolant flow through the coolant jacket.
