A multicellular converter for a low-voltage traction chain. The invention relates to an electric machine and a traction machine utilising said electric machine. The electric traction chain according to the invention comprises an electric machine, a plurality of power converters configured to generate AC power signals associated with the various phases of the electric machine, and a plurality of DC power sources. The electric machine according to the invention comprises a rotor and a stator, the stator comprising at least one winding made from coilings of an insulated conductive material, each winding being associated with one phase of the electric machine, and comprising a plurality of independently powered coils. Each DC power source of the electric machine is associated with a separate power converter, the coils of a same winding are powered by power signals associated with a same phase generated by the separate power converters.
