Abstract: An electric machine comprises an outer casing (2), a rotor and a stator (3) having at least one polar expansion (5) and at least one winding (8) having an annular shape and placed around the polar expansion (5). The casing (2) has a plurality of protrusions (13) each of which holds, by supporting, a corresponding portion (12) of a stator winding (8) to enable heat exchange between the winding (8) and the protrusion (13). Each portion (12) of the winding (8) is electrically insulated from the respective protrusion (13).
