Abstract
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.
