<p>Stator or rotor (1) of an electric machine, comprising:
- a stator or rotor core (2) comprising a main cylindrical body in which a circular array of slots (8) are defined, each slot comprising at least a first (P1) and at least a second (P2) insertion position, radially aligned with respect to each other;
- at least one bar winding comprising a first plurality of basic conductors (U1, U2) having two legs (5) and a connection portion (15) between said legs, said first plurality of basic conductors comprising at least a first set of conductors (U1) having legs offset from each other by a first pitch and a second set of conductors (U2) having legs offset from each other by a second pitch different from the first pitch, the bar winding also comprising a second plurality of special bar conductors (S1-S3) for the completion of the winding having one or more legs, the legs of the conductors of the first and second plurality belonging to a first or a second circular array of legs based on the occupied insertion position. The first and the second circular array comprise:
- a first arc of legs of the first set of conductors delimited by a respective initial and final leg of said conductors;
- a second arc complementary to said first arc in which legs of the second set of conductors are inserted as well as legs of the special bar conductors.</p> |
