PURPOSE:To facilitate wiring and connection work, by alternately arranging winding units different dislocating direction of strands one after another in a unipolar monophasic groove. CONSTITUTION:A three-phase stator winding is formed by connecting the space of winding units with an interpole connecting line which units are composed of multiple hexagonal coils 2 having multiple steps of strands a-f and arranged and formed one after another in a unipolar monophasic groove of stator core grooves 1. With this winding the abovementioned winding units consist of one that dislocated a strand (f) of lower step at the bottom coil lead wire section 5 of a coil 2 to the upper step and connected and formed respectively to the strands f-a at upper coil lead wire section 6 of the adjacent coil 2 and of the other that dislocated the strand (f) to a lower step in the same way and connected and formed. These winding units different in dislocating direction are alternately arranged one after another. Thus, in case the number of unipolar monophasic grooves is less than that of the steps of the strand, the dislocation can easily by performed.
