1. A stator for a rotary electric machine, comprising a stator mass comprising slots, electrical conductors housed in the slots forming a multiphase winding having at least a first phase (a) and a second phase (b), an input electrical conductor (A) of the first phase (a) being located in a first slot, one or more electrical conductors of the second phase (b) being located in a second slot, the second slot immediately following the first slot when moving circumferentially around the axis of rotation of the machine in the direction of flow of the electric current around the axis of rotation of the machine,
wherein the winding comprises U-pins with a width of n slots and U-pins with a width of n−1 slots,
each slot comprising a same number of electrical conductors.
