Abstract
Rotating machinery includes a rotor of 2n poles, 84n slots, and three-phase stator windings, where n is an integer equal to or greater than 1. A top coil and a bottom coil accommodated at the diametrically inner and outer sides of the slot are connected to each other to form the stator winding. The stator windings have 2n phase belts per one phase, the phase belt including two parallel windings. In at least one of the phase belts, the one coils are disposed in the order of the second, first, first, second, first, second, first, second, second, first, second, first, second, and first parallel windings; the other coils connected to the one coils are disposed in the order of the first, second, second, first, second, first, second, first, second, first, first, second, first, and second parallel windings.
