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 mainly concerns a coiling procedure of a stator for a multiphase electrical rotating machine: the said stator comprising grooves, each intended to take up an uneven number of conductors of a coil, the said coil comprising two systems, each comprising one group of conductors (C-C, C'-C&#x2032;) respectively, the said procedure comprises stages of installation of the conductors (C-C, C&#x2032;-C&#x2032;) into the said grooves, repeated in order to form a coil comprising several turns (S-S) completed alternately according to a first direction of rotation (K) and according to a second direction of rotation (K) opposite the first direction of rotation, with the characteristic that at least two changes of direction of rotation (CH-CH) from one turn to the other are carried out in different angular zones.

Coiling procedure for the stator of an electrical rotating machine, and corresponding coiled stator

A rotary electrical machine comprising a rotor and a stator (). The stator comprises a tooth () delimited by notches (), and a winding composed of n&#xd7;M wires (), wherein n corresponds to a number of phases and is equal to at least 2, and M corresponds to a number of continuous electric wires for each phase () and is equal to at least one. The winding is composed of successive turns, each of the successive turns comprising n&#xd7;M wires wound simultaneously in n of the notches () to be inserted in n series of notches. Each of the series of the notches is dedicated to a single phase, and for each of the successive turns, each of the assembly of the M wires () constitutes a phase and is inserted in the same series of the notches ().
