METHOD FOR PRODUCTION OF AN ELECTRICAL MACHINE STATOR WINDING, AND CORRESPONDING STATOR

摘要

The invention essentially relates to a method for the production of a winding of a rotary electric machine stator, comprising the following steps: forming a winding web (52) comprising a plurality of conductors (37); placing the winding web (52) in a comb (83); winding the winding web (52) around a spindle (105) such as to obtain a winding; and transferring the winding from the spindle (105) to the stator, wherein the winding web (52) is wound around the stator (105) over at least two turns.

主权项

1. Wound stator (15) of a rotary electrical machine comprising a body (16) provided with notches (28) delimited by teeth (25) distributed on its circumference, as well as a winding (17), said winding (17) being formed from a winding layer (52) comprising phase windings (E1-E6), each constituted by a single wire (44), each of the phase windings comprising segment structures (38) corresponding to portions of said single wire which are designed to be inserted in said notches (28), and loop structures (39) corresponding to portions of said single wire connecting the segment structures (38) to one another, wherein, with said winding layer (52) having a length substantially equal to K stator circumferences, it is inserted in the notches in said stator (15) body (16) and forms a roll with K layers of winding, K being a whole number equal to 2 or more.
