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 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 ().

Method for production of electrical machine stator comprising preforming step, and corresponding wound stator

The invention relates mainly to an outer stator () for a rotary electric machine, comprising a body () provided with a yoke and teeth (), with slots () being defined between pairs of teeth, as well as a winding comprising conductors having segment structures () inserted inside the slots (). In the stator, the ratio between the width of a slot (L) covered with a slot insulator () and the width of a segment structure () covered with enamel (L) is between 0.9 and 2.

Electrical machine stator with optimized notch filling, and corresponding method for production of the stator

The invention essentially relates to an outer stator () for a rotary electric machine, comprising a body () equipped with a yoke and teeth () arranged on the internal periphery of the yoke (), with slots () being defined between pairs of teeth (), in which the teeth do not have roots and the stator also comprises corners () at the free ends of the teeth () that are curved according to a radius (R), known as the radius of entry (R).
