Abstract: A guiding device is for the winding of electrically conductive wires about a plurality of poles of a rotor of an electric machine that are distributed about a shaft extending axially in the rotor. The device includes a guide head that is able to be mounted on the shaft. The guide head includes a metallic basic structure provided with a plurality of arms that extend radially from an inner part of the metallic basic structure provided with a central orifice, and a plastics structure overmoulded on the metallic basic structure, in a set-back manner with respect to an internal cylindrical surface of the central orifice, such that the internal cylindrical surface of the central orifice of the metallic basic structure is designed to be in direct contact with the shaft of the rotor for mounting on the shaft of the rotor with an interference fit.

Abstract: A rotor includes an assembly of laminations including a plurality of radially-projecting poles, a winding of electrically conductive wires to be wound around each pole by means of wire-guiding heads arranged axially on either side of the lamination assembly. A guiding head support is inserted between the lamination assembly and each guiding head such that: an internal radial face of the support abuts against an external radial face at an axial end of the lamination assembly; and a peripheral surface of the support, which projects axially outward from the internal radial face of the support, is in contact with a contact face of the guiding head that is orientated radially outward from same, the guiding head abutting against the peripheral surface of the support.

Abstract: A cage for a wound rotor includes a first portion and a second portion to be rigidly connected to one another. Each portion includes an end ring and a circumferential plurality of rods extending away from the end ring parallel to the axis of revolution of the end ring. Each rod has a main portion and an end portion. For each rod of the first portion, the end portion of the rod is shaped to be rigidly connected to the end portion of at least one complementary rod of the second portion when the two portions are each installed at a longitudinal end of the body of the rotor so that the two complementary rods rigidly connected form a slot wedge extending between the two end rings of the two portions of the cage.
