Claim:
1. A stator winding for a rotating electrical machine, comprising: a plurality of stator phase windings assuming a plurality of phases, which each includes a plurality of round windings wound with a wave winding pattern, each having slot conductors each inserted at one of the slots at a stator core to form one of a plurality of layers and cross conductors each connecting same-side ends of slot conductors inserted at different slots so as to form a coil end, wherein: the cross conductors connect the slot conductors so as to run astride slots with the slot pitch Np set to N+1 at coil ends on one side and run astride slots with the slot pitch Np set to N−1 at coil ends on another side, with N representing a number of slots per pole; the stator phase windings each include stator winding groups that have no phase difference therebetween in a single phase; the stator phase windings each includes a plurality of slot conductor groups each having a plurality of slot conductors corresponding to a single phase; the plurality of slot conductors in each slot conductor group are inserted at a predetermined number Ns of successive slots forming a continuous range along a circumference of the stator core so that the slot conductors in the slot conductor group take successive slot positions and successive layer positions; and the predetermined number Ns is set so that Ns=NSPP +NL when NSPP represents a number of slots per phase per pole and NL represents a number of layers divided by two.
