- the invention finds applications in the field of rotating electrical machines such as alternators or reversible machines that can operate as an electric generator or an electric motor.
- rotating electrical machines comprise a stator and a rotor secured to a shaft.
- the rotor may be integral with a driving and / or driven shaft and may belong to a rotating electric machine in the form of an alternator, an electric motor or a reversible machine of the alternator-starter type capable of operating in two modes.
- the stator is mounted in a housing configured to rotate the shaft on bearings via bearings.
- the rotor is for example of the “claw rotor” type and comprises two pole wheels each having claws nested in one another to form the poles and a core around which a rotor coil is wound.
- the rotor comprises a body formed by a stack of metal sheets held in the form of a package by means of a suitable fixing system.
- the rotor has poles formed for example by permanent magnets housed in cavities formed in the magnetic mass of the rotor.
- the poles are formed by coils wound around the rotor arm.

These phase windings of the winding 120 pass through the notches 111 of the stator body and form a chignon 125, 126 on either side of the stator body 110.
- the phase windings of the winding 120 are polyphase windings, connected in a star or in delta, of which one end of each phase winding of the winding forms a phase output 123 and each phase output 123 is connected to an electrical control module and the other end of each phase winding of the winding forms a connection point 122 connected either together in the case of a star assembly forming the neutral point or in the case of a delta assembly to a phase output 123 of another winding.
- the phase windings of the coil 120 are obtained from conductive elements in the form of pins 121.
- a pin 121 has two branches connected by a curved head, or collateral portion, and whose intermediate rectilinear portions, or portions central, are placed in two different notches angularly offset from each other by a predetermined angle.
