Method for winding an electric machine rotor
A wound rotor, such as a wound rotor for an electric machine, includes a shaft having a main axis. The shaft includes a manifold. The wound rotor also includes a winding wire and n poles wound and ordered with an ascending order number obtained by rotation about the main axis. The n wound poles can be distributed radially about the main axis. The n poles are wound with the wire in series in turn according to their ascending order numbers, the last pole, however, not being wound last.
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.
2. The wound rotor as claimed in claim 1 , wherein the n wound poles are distributed radially about the main axis.
3. The wound rotor as claimed in claim 1 , wherein a penultimate pole of the n wound poles is wound after the last pole.
4. The wound rotor as claimed in claim 1 , wherein an antepenultimate pole of the n wound poles is wound after the last pole.
5. The wound rotor as claimed in claim 1 , wherein upstream of a first pole of the n wound poles, the wire rests against the shaft at a first non-zero angle about the main axis.
6. The wound rotor as claimed in claim 1 , wherein downstream of the last pole to be wound, the wire rests against the shaft at a second non-zero angle about the main axis.
7. The wound rotor as claimed in claim 1 , further comprising:
pins configured to facilitate the winding of the wire.
8. The wound rotor as claimed in claim 7 , wherein the pins run parallel or substantially parallel to the main axis.
9. The wound rotor as claimed in claim 1 , further comprising:
pins configured to facilitate the winding of the wire between two adjacent poles and/or between each pole and the shaft and/or the slipring.
10. The wound rotor as claimed in claim 9 , wherein the pins run parallel or substantially parallel to the main axis.
11. An electric machine, comprising:
the wound rotor as claimed in claim 10 .
12. A vehicle, comprising:
the electric machine as claimed in claim 11 .
13. The vehicle as claimed in claim 12 , wherein the vehicle is a motor vehicle.
14. A vehicle, comprising:
the wound rotor as claimed in claim 10 .
15. The vehicle as claimed in claim 14 , wherein the vehicle is a motor vehicle.
16. A method for obtaining the wound rotor as claimed in claim 1 , comprising:
winding the n poles with the wire in series turn by turn in their ascending numerical order, although the last pole is not the last to be wound.
