っている。The winding diagram shown in Fig. 1 is the same as the conventional example shown in Fig. 2 (an example of a three-phase AC single-layer double winding with 3G grooves, 4 poles, and 3 grooves per phase per pole. Mount the three-phase AC armature coil on the stator core so as not to straddle the stator divisions A-B and A'-B', and reverse the bending direction of the ends of the adjacent armature coils. They have the same configuration in that they are connected by a connecting line M between poles.

できる。As can be seen from FIG. 7, the vector V1 in FIG.
The voltage vector is the same as the normal three-phase AC single-layer overlapping voltage vector shown in the figure. However, coil numbers 31 to 33
The difference is that the coil numbers 13 to 15 are switched in the coil order, but the vector positions are the same, and the vector shapes are the same after all.
This point also applies to the voltage vector V3 in FIG. Therefore, the phase angles between the phases of the first vector on the neutral point side are exactly 120 degrees apart and are completely symmetrical. As a result, generation of harmful circulating current can be suppressed.
