Abstract
A rotor (2), especially for an electrical rotating machine, for example for an alternator, comprising an electric winding (100) formed by at least one electric wire (101), the wire comprising: at least one first portion (104) wound as at least one turn of the winding; a transverse section with at least one flat (115) along the first portion; at least one second portion (105) allowing the connection of the winding to an electric circuit; and an essentially circular transverse section along the second portion.

A rotor (2) for a rotary electrical machine, comprising:
- a coil (10) comprising a hub (11) and an electrical winding (100) wound on the hub (11);
- and
- a collector assembly (60);
- the coil (10) formed by an electric wire (101) including a first portion (104) wound to form the electrical winding (100) of a rectangular cross-section, and a second portion (105) disposed outside the hub (11) and configured to connect the electrical winding to the collector assembly (60);
- the first portion of the electric wire forming radially inner turns (102) of the electrical winding (100) having a transverse cross-section with at least one flattened part (115) parallel to an axis of rotation of the rotor, and a radially outer turn (107) having a circular transverse cross-section;
- the electric wire having a substantially circular transverse cross-section along the second portion of the electric wire.
A coil (10) for a rotor of a rotary electrical machine, comprising:
- a hub (11) of the coil (10);
- and
- an electrical winding formed by an electric wire wound on the hub (11) of the coil (10);
- the electric wire including a first portion having a plurality of turns wound on the hub (11) to form the electrical winding (100) of a rectangular cross-section, and a second portion disposed outside the hub (11) and configured to connect the electrical winding to a collector assembly (60);
- the first portion of the electric wire forming radially inner turns (102) of the electrical winding (100) having a transverse cross-section with at least one flattened part (115) parallel to an axis of rotation of the rotor, and a radially outer turn (107) having a circular transverse cross-section;
- the electric wire having a substantially circular transverse cross-section along the second portion of the electric wire.
A rotor (2) for a rotary electrical machine, comprising:
- a coil (10) comprising a hub (11), and an electrical winding (100) wound on the hub (11);
- and
- a collector assembly (60);
- the electrical winding (100) formed by an electric wire (101) having a connection portion (108) disposed outside the hub (11) and configured to be connected to a connection lug (61) of the collector assembly (60);
- the electric wire including a first portion (104) having a plurality of turns wound to form the electrical winding (100), and a second portion (105) disposed outside the hub (11) and configured to connect the electrical winding to the collector assembly (60);
- the first portion of the electric wire having a transverse cross-section with at least one flattened part (115) parallel to an axis of rotation of the rotor;
- the electric wire having a circular transverse cross-section along the second portion;
- the connection portion (108) having a circular cross-section along an entire length thereof and formed partially on the first portion (104) of the electric wire (101) with the rectangular transverse cross-section, and partially on the second portion (105) of the electric wire (101) with the circular cross-section;
- wherein the electrical winding comprises:
- radially inner turns (102) having a transverse cross-section with at least one flattened part (115) parallel to the axis of rotation of the rotor;
- and
- a radially outer turn (107) having a circular transverse cross-section.
