Abstract
In a three-phase, four-pole, four-parallel-circuit stator winding of an electrical rotating machine, each of two sets of U-phase output terminals U, Uis formed of two sets of parallel circuits each formed of windings having a same pitch (one is formed of first and second winding circuitsand the other is formed of third and fourth winding circuits). The winding of each winding circuit is formed of two serially-connected coil phase bands (coil phase bands a and b form the first winding circuitand coil phase bands c and d, coil phase bands e and f, and coil phase bands g and h form the second, third, and fourth winding circuits, respectively). A voltage vector phase difference and a voltage difference between the winding circuits can be eliminated without providing a jumper wire to winding end portions.
