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).

Electrical machine stator with small input radius, and corresponding method for production of the 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 ().

Winding for rotary electrical machine

A method and device for winding a rotor or a stator (), of a rotary electrical machine, having a series of teeth () which are delimited by notches (). In each notch there are inserted M continuous electric wires () constituting a turn; M being equal to 1 or more, characterised in that n&#xd7;M wires () are wound simultaneously in a number n of notches (), n corresponding to the number of phases and being &#x2267;2. The assembly of the M wires () constituting a phase, being inserted in a single notch (). The device for winding has at least two carriages (), with a series of teeth, delimited by n notches (). And, likewise corresponding to the winding, each set of M continuous electric wires () constituting a turn, is characterised in that M&#xd7;n wires () are inserted simultaneously in the extension of the n notches () of the rotary electrical machine in the n notches () in the respective carriages (). All of the M&#xd7;n wires () are bent together at least twice by bending the carriages () relative to one another, and all of the M&#xd7;n wires () thus bent are folded back in the following successive nnotches () of the rotary electrical machine.
