Abstract
The invention relates to a stator tooth (8) for an electrical machine, the stator tooth being intended for holding an electrical wire winding (10). The tooth includes a central portion (24) formed with a contiguous assembly of precut magnetic metal sheets (24a). The metal sheets are secured to one another. The tooth is characterized in that the central portion (24) is enclosed between two longitudinal end portions (25) which are secured to the central portion (24) and each have a radial attachment bolt (11) passing therethrough. The longitudinal end portions (25) have a rounded outer shape (25a) for forming, on the ends of the tooth, a continuous contact surface for the electrical wire(s) wound onto the tooth.
