The invention proposes a stator for a rotating electric machine, in particular for a motor vehicle, the stator () including: &#x2014;a body () including notches () that are opened radially into an internal wall () of said body, &#x2014;at least one winding () forming a phase of the stator, the winding formed from turns () includes a first half-phase () and a second half-phase () that are superposed radially in the notch (), each turn including a series of axial strands () that are received in a series of associated notches and connecting strands () that connect the successive axial strands () by extending alternatively to protrude with respect to the body (). 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.

Coiled stator for a rotary electrical machine

Rotating electric machine provided with an axis X. The machine comprises a front part and a rear part. The machine comprises a rotor of axis X comprising two axial end surfaces, each provided with fan blades. The axial surfaces located on the side of the front part and on the side of the rear part. A stator comprises a stator body having slots. The stator comprises a winding installed in the slots and forming a front winding head and a rear winding head. The rotor and the stator are placed in a casing. The front winding head completely masks the blades of the axial surface located on the front side of the machine, along a direction perpendicular to axis X.
