Abstract
An automatic winding device for winding wire onto a pole of a multi-pole rotor, the pole includes a bottom and a head, the device comprising: a support vice supporting the rotor and capable of rotational movement about a first axis, a needle plate, centred on the pole along the first axis and comprising four placement needles, which is capable of translational and rotational movement about the first axis, a conducting wire, attached to the rotor and to a wire winder, in contact with at least one placement needle, the winding device being able to perform a number of sequences from an “initial configuration” to a “winding configuration” wherein, successively, the needle plate is rotated and the pole is moved translationally with respect to the needle plate along the first axis so as to wind the conducting wire around the pole as far as a “final configuration”.
