Abstract
A method and device for winding a rotor or a stator (2), of a rotary electrical machine, having a series of teeth (21) which are delimited by notches (22). In each notch there are inserted M continuous electric wires (3) constituting a turn; M being equal to 1 or more, characterised in that n×M wires (3) are wound simultaneously in a number n of notches (22), n corresponding to the number of phases and being ≧2. The assembly of the M wires (3) constituting a phase, being inserted in a single notch (22). The device for winding has at least two carriages (4, 5), with a series of teeth, delimited by n notches (40, 50). And, likewise corresponding to the winding, each set of M continuous electric wires (3) constituting a turn, is characterised in that M×n wires (3) are inserted simultaneously in the extension of the n notches (22) of the rotary electrical machine in the n notches (40, 50) in the respective carriages (4, 5). All of the M×n wires (3) are bent together at least twice by bending the carriages (4, 5) relative to one another, and all of the M×n wires (3) thus bent are folded back in the following successive n1 notches (22) of the rotary electrical machine.
