Abstract
A rotating electrical machine stator comprising an annular cylindrical body including axial grooves, and at least one phase winding including corrugated turns of wire, the phase winding comprising a first outer half-phase and a second inner half-phase which are radially superimposed, the first outer half-phase including outer leading-out wires projecting from the radial walls of the body and the second inner half-phase including outer leading-out wires projecting from the radial walls of the body. The invention is characterized in that for each phase winding, the wire length of each turn of the inner half-phase is greater than the wire length of each turn of the outer half-phase. The invention also concerns a phase winding designed to be mounted in such a rotor.
