Three-phase stator winding of a rotary electric machine

A three-phase stator winding of a rotary electric machine and comprising:

• a plurality of coils each of which has two opposite ends;
• at least one first connection bridge which defines a star connection of at least three coils and constitutes a star centre of the three coils by connecting a first end of each one of the three coils to one another;
• and
• three second connection bridges which define a parallel connection of the star connections, are each provided with a corresponding pin defining a terminal of the three-phase stator winding towards the outside, and each of which connects a second end of a respective coil of each star connection to one another;
• wherein each second connection bridge has a circular shape closed onto itself without interruptions;
• and
• wherein each second connection bridge has a variable cross section along its circumferential extension.
