Abstract
The invention relates to a stator (2) comprising an annular body (4) having a side face (6) from which a plurality of radial teeth (8) extend, said teeth being angularly spaced in such a way as to define slots (10), and a plurality of conductive needles (15A, 15B), each conductive needle comprising two conductive segments (16A, 16B, 16C, 16D) connected by an elbow connector (18), the conductive segments being stacked one above the other in the slots (10) so as to form N layers which are parallel or substantially parallel to the side face (6) of the annular body. Each conductive needle (15A, 15B) comprises a conductive segment present in two separate slots, with one conductive segment present in a slot E in such a way as to occupy a layer (Ci) and another conductive segment present in a slot E+P in such a way as to occupy a layer (Ci+2), P being a pitch that is predetermined in a first direction of orientation.
