<p><P>PROBLEM TO BE SOLVED: To provide a rotary electric machine capable of securing insulation without making a device large-sized and also decreasing the number of columns of overhead lines. <P>SOLUTION: A rotary electric machine includes a three-phase armature winding having: at least one electrode constituted by storing two coils in slots extending to an armature iron core in an axial direction and provided at predetermined intervals in a peripheral direction, and sequentially connecting the coils in series one after another; and a plurality of wiring circuits having line-side overhead lines connecting line-side terminals and the coils and middle point-side overhead lines connecting middle point-side terminals and the coils, at least one winding circuit of each phase among the winding circuits having inter-electrode overhead lines connecting two different electrodes constituted by sequentially connecting the coils in series one after another. Then, the rotary electric machine has at least one place where peripheral positions where the line-side overhead lines and the coils are connected are substantially the same among the different phases and at least one place where peripheral positions where the middle point-side overhead lines and the coils are connected are substantially the same among different phases. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
