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.
