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.
