Abstract
In a three-phase armature winding of the concentrically wound double-layer type, coil ends of three-phase first pole windings are distributed on an outermost circumference and coil ends of second and other pole windings are distributed on inner circumferences in turn in a first arrangement. In a second arrangement, coil sides of three-phase first pole windings and second pole windings paired with the first pole windings in a three-phase six-pole arrangement are laid in adjacent slots in sequence. This coil arrangement is applied to paired fifth and fourth pole windings.
