More Information
Summary:The invention concerns a rotating electrical machine stator (11) comprising an annular cylindrical body (10) including axial grooves (20), and at least one phase winding (30) including corrugated turns (32) of wire (33), the phase winding (30) comprising a first outer half-phase (38E) and a second inner half-phase (38I) which are radially superimposed, the first outer half-phase (38E) including outer leading-out wires (40E) projecting from the radial walls (16, 18) of the body (10) and the second inner half-phase (38I) including outer leading-out wires (40I) projecting from the radial walls (16, 18) of the body (10). The invention is characterized in that for each phase winding (30), the wire length (33) of each turn (32) of the inner half-phase (38I) is greater than the wire length (33) of each turn (32) of the outer half-phase (38E). The invention also concerns a phase winding (50) designed to be mounted in such a rotor (11). ® KIPO & WIPO 2008
