Abstract: The winding bars (12) are fixed to the body (20) of teeth (14, 16) whose feet (18) form a dovetail engaged in the stator magnetic circuit (2), the mechanical strength of these teeth being due to the fact that they are constituted by layers of sheathing fabric coated with resin completely wrapped about the foot, body and head of the core of each of the teeth and forming a casing (46). Wedges (28) are driven in radially on the side walls of the teeth whose thickness is substantially constant around a core (40) whose form defines that of the tooth.

Abstract: The stator winding bars (12) e.g. of an alternator are fixed to the magnetic circuit (2) by means of teeth (14, 16) fixed on the cylindrical inner surface (44) of said circuit and protruding inwardly therefrom. Successive teeth going circumferentially round the cylindrical surface are alternately long teeth (14) and short teeth (16). The bars are tangentially wedged by wedges (28) driven radially between the bars and the side walls of the short teeth (16). The bars are held radially by plates (30) which are kept in position by means of tapering pins (32) driven tangentially into holes (44) provided in the heads (29) of the long teeth (14).
