Abstract
A rotating electric machine, in which a cross conductors of a stator connect slot conductors so as to stride N+1 slots at coil ends on one side and stride N−1 slots at coil ends on another side, with N representing a number of slots per pole, a stator winding includes a plurality of slot conductor groups each made up with 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, Ns=NSPP+NL when NSPP represents a number of slots per pole per phase and a number of layers is expressed as 2×NL.
