PURPOSE:To constitute an armature winding with a ratio of number of poles of 6 to 8 and having fewer terminals, by forming a first phase to a third phase by a first and a second winding groups enclosed to the predetermined number of grooves. CONSTITUTION:Windings are consecutively enclosed to two sets of consecutive three grooves and to consecutive four and two grooves respectively in overlapped winding method for total 72 grooves in number and connected in series to form the first winding group A1-A4 and C1-C4 and the second winding group A5-A8 and C5-C8 of the same composition, forming a U-phase and a W-phase. Windings are consecutively enclosed to two sets of one groove, two sets of consecutive three grooves and four grooves respectively and connected in series to form a first winding group B1-B5 and a second winding group B6-B10, forming a V-phase. By a change of connection of these winding groups the current direction of the first winding group for each phase is reversed to carry out the pole-change.
