Abstract
Disclosed is an electric machine and a traction machine utilizing the electric machine. The electric traction chain includes 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 includes a rotor and a stator, the stator including at least one winding made from coilings of an insulated conductive material, each winding being associated with one phase of the electric machine, and including 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.
