1. A wound rotor, comprising:
a shaft with main axis, the shaft comprising a slipring;
a winding wire; and
n wound poles ordered in ascending numerical order obtained by rotation about the main axis,
wherein the n wound poles are wound with the wire in series turn by turn according to their ascending numerical order, although a last pole of the n would poles is not the last to be wound.
