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.
