摘要： 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.

摘要： The invention relates to a rotary electric machine for a vehicle comprising an electronic assembly, a stator and an electrical phase connector (10) for a rotary electric machine stator (20). The electrical phase connector (10) comprises a predefined angular configuration of electrical coupling means (130b) so as to carry, respectively, a different electrical phase toward or away from a rotary electric machine stator (20). Each electrical coupling means (130b) is electrically connected to a conductive phase track (110).

摘要： The invention proposes a stator for a rotating electric machine, in particular for a motor vehicle, the stator (15) including: —a body (27) including notches (37) that are opened radially into an internal wall (40) of said body, —at least one winding (43) forming a phase of the stator, the winding formed from turns (54) includes a first half-phase (49) and a second half-phase (50) that are superposed radially in the notch (37), each turn including a series of axial strands (44) that are received in a series of associated notches and connecting strands (45, 46) that connect the successive axial strands (44) by extending alternatively to protrude with respect to the body (27). A length of wire of each turn of one of the half-phases is larger than the length of wire of each turn of the other half-phase. Furthermore, one of the half-phases has a number of turns higher than that of the other half-phase.
