The invention relates to a stator () comprising an annular body () provided with a plurality of slots () and a winding () comprising a first series (A) of needles () and a second series (B) of needles () which are arranged in the slots () in a plurality of superimposed layers (C-C), each needle () comprising a first segment (A) and a second segment (B) which are each arranged in different slots () and connected by an elbow connector (C). According to the invention, the first segments (A) and the second segments (B) of the first series (A) are respectively arranged in a first layer (C) and in a second layer (C) and the first segments (A) and the second segments (B) of the second series (B) are respectively arranged in a third layer (C) and in a fourth layer (C), the first series (A) being electrically connected to the second series (B).

Stator for a rotary electrical machine

The invention relates to a stator () comprising an annular body () having a side face () from which a plurality of radial teeth () extend, said teeth being angularly spaced in such a way as to define slots (), and a plurality of conductive needles (A,B), each conductive needle comprising two conductive segments (A,B,C,D) connected by an elbow connector (), the conductive segments being stacked one above the other in the slots () so as to form N layers which are parallel or substantially parallel to the side face () of the annular body. Each conductive needle (A,B) 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.

Stator for a rotating electrical machine

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

Electrical phase connector for a stator of a rotary electric machine

The invention proposes a stator for a rotating electric machine, in particular for a motor vehicle, the stator () including: &#x2014;a body () including notches () that are opened radially into an internal wall () of said body, &#x2014;at least one winding () forming a phase of the stator, the winding formed from turns () includes a first half-phase () and a second half-phase () that are superposed radially in the notch (), each turn including a series of axial strands () that are received in a series of associated notches and connecting strands () that connect the successive axial strands () by extending alternatively to protrude with respect to the body (). 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.

Coiled stator for a rotary electrical machine

The invention essentially relates to a method for the production of a winding of a stator () comprising a body equipped with slots (), comprising: a supply step consisting in supplying a winding unit with a bundle of conductors (); and a pre-forming step consisting in moving the winding unit in relation to the bundle of conductors (), such as to obtain a bundle of conductors () having, for each phase winding (E-E), at least two loop structures () and at least three segment structures (), two of the segment structures () being positioned such that they can be disposed in the same slot () of the stator () and the two loop structures () connecting said two segment structures () stacked on the third segment structure ().
