Disclosed is a stator () comprising a stator body () having notches () formed between teeth (), electrical conductors () being housed in the notches (), at least one part of the electrical conductors being in the form of a U-shaped pin, each comprising first () and second () axially extending legs in the first (A) and second (R) notches, respectively, at least one of the first () and second () legs of the electrical conductors () extending out of the notches via an inclined welding portion, at least one part of the electrical conductors each having a welding portion, innermost with respect to the longitudinal axis of the stator, the innermost welding portions being inclined with the same inclination with respect to the plane perpendicular to the longitudinal axis of the stator.

Rotary electric machine stator with asymmetric winding

Stator () for a rotary electric machine (), comprising a stator mass () comprising slots (), electrical conductors () accommodated in the slots () forming a multiphase winding having at least a first phase (a) and a second phase (b), an input electrical conductor (A) of the first phase (a) being located in a first slot (slot number), one or more electrical conductors of the second phase (b) being located in a second slot (slot number), the second slot immediately following the first slot when going circumferentially around the axis of rotation of the machine, in the direction of flow of the electric current around the axis of rotation of the machine.

Rotary electric machine stator with simplified winding

A method for welding a plurality of strands of one or more electrical conductors comprises at least the following steps: (a) preparing the strands to be welded such that at least the free ends of adjacent strands are axially offset by a non-zero distance d; and (b) melting the free ends of the strands thus arranged in order to weld them without addition of material.
