1. An electric machine, comprising:
a manifold having an insulative plate formed of an electrically insulative material and a backplate positioned adjacent to the insulative plate and formed of an electrically conductive material, wherein the insulative plate and the backplate define a first channel and a second channel therebetween, and wherein the insulative plate is segmented into at least two segments along a circumferential direction;
a winding; and
a terminal conductor extending through the backplate and the insulative plate, the terminal conductor being electrically coupled with the winding and electrically isolated from the backplate, the terminal conductor also being in fluid communication with the winding so that cooling fluid can flow therebetween.
