  • Dovetailed teeth for use in a system for fixing stator winding bars in a rotating electric machine
    Patent number: 4380713
    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.
