摘要： The invention essentially relates to an outer stator (15) for a rotary electric machine, comprising a body (16) equipped with a yoke and teeth (25) arranged on the internal periphery of the yoke (26), with slots (28) being defined between pairs of teeth (25), in which the teeth do not have roots and the stator also comprises corners (31) at the free ends of the teeth (25) that are curved according to a radius (R), known as the radius of entry (R).

摘要： The invention relates mainly to an outer stator (15) for a rotary electric machine, comprising a body (16) provided with a yoke and teeth (25), with slots (28) being defined between pairs of teeth, as well as a winding comprising conductors having segment structures (38) inserted inside the slots (28). In the stator, the ratio between the width of a slot (L1) covered with a slot insulator (145) and the width of a segment structure (38) covered with enamel (L2) is between 0.9 and 2.

摘要： The invention essentially relates to a method for the production of a winding of a stator (15) comprising a body equipped with slots (28), comprising: a supply step consisting in supplying a winding unit with a bundle of conductors (37); and a pre-forming step consisting in moving the winding unit in relation to the bundle of conductors (37), such as to obtain a bundle of conductors (37) having, for each phase winding (E1-E6), at least two loop structures (39) and at least three segment structures (38), two of the segment structures (38) being positioned such that they can be disposed in the same slot (28) of the stator (15) and the two loop structures (39) connecting said two segment structures (38) stacked on the third segment structure (38).
