The invention proposes a stator for a rotating electric machine, in particular for a motor vehicle, the stator (15) including: —a body (27) including notches (37) that are opened radially into an internal wall (40) of said body, —at least one winding (43) forming a phase of the stator, the winding formed from turns (54) includes a first half-phase (49) and a second half-phase (50) that are superposed radially in the notch (37), each turn including a series of axial strands (44) that are received in a series of associated notches and connecting strands (45, 46) that connect the successive axial strands (44) by extending alternatively to protrude with respect to the body (27). A length of wire of each turn of one of the half-phases is larger than the length of wire of each turn of the other half-phase. Furthermore, one of the half-phases has a number of turns higher than that of the other half-phase.
