Abstract
A stator of a rotary electric machine is supported in a housing structure and is secured therein against relative rotation or axial movement by angularly spaced fasteners. A circumferential passage in the stator communicates with a supply passage for liquid coolant. The temperature coefficients of expansion of the materials of the housing and the stator differ so that below a predetermined temperature those parts are an interference fit, and above that temperature channels are created between the fasteners, through which channels coolant can flow axially from the passage.
