Abstract
A stator for an electrical machine includes: an annular housing extending around a central axis (X-X); a first circumferential flow channel extending around the housing; a second circumferential flow channel axially spaced from the first circumferential flow channel and extending around the housing; and a plurality of windings. The plurality of windings are circumferentially spaced about the housing to form a passage between each two adjacent windings. Each passage is in fluid communication with both the first circumferential flow channel and the second circumferential flow channel. The first circumferential flow channel is closed to flow at a first circumferential location and the second circumferential flow channel is closed to flow at a second circumferential location, removed from the first circumferential location so as to form a first set of passages (S) connected in parallel and a second, separate set of passages (S) connected in parallel.
