1. An electric winding for an active portion, which portion is in particular formed of a stator or of a rotor, of a rotary electric machine, the active portion having a body comprising an annular yoke about an axis and a plurality of teeth that extend from a lateral face of the yoke in a radial direction so as to define slots, said slots opening onto a first axial end face and onto a second axial end face of the body; the electric winding having at least one phase system comprising a plurality of electrical phases each comprising a set of pins that are electrically connected to one another and that each have at least one conductive segment, said conductive segments intended to be housed in the same slot forming N layers (Ci), said set of pins comprising a first energizing pin and a second energizing pin each forming a phase input or output, each energizing pin having an energizing end extending from the associated conductive segment to outside the slot and each energizing end forming a phase output being electrically connected to another energizing end forming a phase input of a different phase in order to achieve a delta configuration, the winding being wherein a first set, formed of energizing pins of various phases placed in a first layer among the N layers (Ci), comprises at least one energizing end forming a phase input and at least one other energizing end forming a phase output and in that a second set, formed of energizing pins of various phases placed in a second layer among the N layers (Ci), which second layer is different from said first layer, comprises at least one energizing end forming a phase input and at least one other energizing end forming a phase output,
wherein, in a set comprising at least three first ends, the phase inputs/outputs are alternated along the circumference of the winding, and,
wherein, for a phase system comprising a number Z of electrical phases, Z being an integer higher than or equal to 3, the energizing pins are placed, along the circumference of the stator, in the following order:
a. for the first set: the energizing end forming the output (O/Z+2) of the third phase, then the energizing end forming the input (I/Z) of the first phase, then the energizing end forming the output (O/Z+1) of the second phase, and for the second set: the energizing end forming the input (I/Z+2) of the third phase, then the energizing end forming the output (O/Z) of the first phase, then the energizing end forming the input (I/Z+1) of the second phase; or
b. for the first set: the energizing end forming the output (O/Z+1) of the second phase, then the energizing end forming the input (I/Z) of the first phase, then the energizing end forming the output (O/Z+2) of the third phase, and for the second set: the energizing end forming the input (I/Z+1) of the second phase, then the energizing end forming the output (O/Z) of the first phase, then the energizing end forming the input (I/Z+2) of the third phase; or
c. for the first set: the energizing end forming the output (O/Z) of the first phase, then the energizing end forming the input (I/Z+2) of the third phase, then the energizing end forming the output (O/Z+1) of the second phase, and for the second set: the energizing end forming the input (I/Z) of the first phase, then the energizing end forming the output (O/Z+2) of the third phase, then the energizing end forming the input (I/Z+1) of the second phase.
