1. An automatic winding device for winding wire onto a pole of a multi-pole rotor, the pole comprising a bottom and a head, the automatic winding device being characterized in that it comprises:
a support vice supporting the multi-pole rotor and capable of rotational movement about a first axis passing through the pole of the multi-pole rotor,
a needle plate, centred on the pole of the multi-pole rotor along the first axis, the needle plate comprising four placement needles, the needle plate being capable of translational and rotational movement about the first axis,
a conducting wire attached to the multi-pole rotor at a first end of the conducting wire and to a wire winder at a second end of the conducting wire, the conducting wire being in contact with at least one placement needle,
the automatic winding device being able to perform a predetermined number of sequences from an initial configuration wherein each placement needle applies a predetermined pressure to the pole at a predetermined angle with respect to the first axis to a winding configuration wherein a rotation of the needle plate equivalent to a full rotation of the pole about the first axis and a translational movement of the pole with respect to the needle plate by a length equal to a diameter of the conducting wire along the first axis occur in succession so as to wind the conducting wire around the pole, as far as a final configuration wherein each placement needle is distant from the pole along a second axis that is radial to the needle plate.
