Abstract

Guiding device for winding an electric machine rotor. Guiding device (1) for winding an electrically conductive wire (10) around a plurality of poles of a rotor (2) of an electric machine, the guiding device (1) comprising a base (3) having a central opening (O) configured to be traversed by the rotor shaft (2), the base (3) having on one side an inner face intended to be oriented towards the poles of the rotor (2) and on the other side an outer face (5), the inner face (4) and the outer face (5) being connected to each other by a side wall (6) from which radial arms (7) extend, the guiding device (1) being characterized in that the side wall (6) has a first notch (8) and a second notch (9) configured to receive the electrically conductive wire (10), and in that the outer face (5) has at least one guiding rib (21,22) configured to serve as a support surface for the electrically conductive wire (10).
