Claim Text:
1. A stator winding of an electrical rotating machine, wherein: each phase of a three-phase, four-pole, four-parallel-circuit stator winding of an electrical rotating machine is placed on a circumference and formed of two sets of parallel circuits, in each of which two winding circuits formed of winding groups having a same pitch are connected in parallel; center axes of the winding groups of the two winding circuits in a same set of the parallel circuits are placed at positions spaced by 360 electrical degrees; the winding group of each winding circuit is formed of two coil phase bands which are connected in series and have winding directions different from each other; and the two coil phase bands are placed at mirror symmetrical positions with respect to the center axis of the winding group of the winding circuit.
