ABSTRACT:
A stator of a rotating electric machine includes a stator core, multiple pairs of coils and multiple leads. The stator core includes a laminated core assembly formed by laminating thin steel plates in a cylindrical form, the stator core having multiple slots at intervals along a circumferential direction. Each coil pair is made of two elongate conductors which are folded back outside axial end surfaces of the stator core and fitted into the slots such that the two conductors are disposed alternately in inner and outer layers in a slot depth direction at intervals of a fixed number of slots. The multiple leads for connecting the coil pairs to an external electric circuit are arranged in at least one group and the leads of the same group extend from positions of those slots which are located adjacent to one another along the circumferential direction.
