Abstract
A stator (1) of a rotary electric machine includes a body (2) provided with slots (15), a coil (3) constituted of windings (4, 5, 6, 7, 8) that include first conductive segments (19) equipped with two first branches and second conductive segments (25) provided with two second branches. Each conductive segment is coated with insulation except for the presence of a bared surface on each one of the branches. The shapes of the bared surfaces complement one another. The first and second conductive segments are arranged in a staggered configuration and in opposite directions successively one after the other, with each slot accepting first branches and second branches positioned opposite with the bared surfaces thereof respectively in contact with one another in such a way as to form a continuous wire. The stator includes elements for keeping the bared surfaces in contact with one another in the slots.
