1. A turbomachine comprising:
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;
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 including an e-machine housing that houses at least part of the e-machine;
a coolant jacket that is defined at least partly in the e-machine housing by a first support surface, the coolant jacket configured to receive a fluid coolant flow therein for cooling the e-machine; and
a turbulator insert member that includes a second support surface and that is removably received within the coolant jacket, the second support surface abutting the first support surface to secure the turbulator insert member within the coolant jacket, the first support surface and the second support surface facing in opposite circumferential directions with respect to the axis of rotation, the turbulator insert member sub-dividing the coolant jacket for directing the fluid coolant flow through the coolant jacket.
