In a method of inserting motor coils and slot insulators, a coil inserting jig is moved between a layer insulator inserter and a wedge inserter, and a core holder is moved between a predetermined location and the wedge inserter, so that a stator core is fitted onto the coil inserting jig when the coil inserting jig is located at the wedge inserter. The coil inserting jig receives layer insulators from the layer insulator inserter. The layer insulators are inserted into slots of the core with lower coils. Wedges are inserted into the core slots with upper coils when the coil inserting jig is located at the wedge inserter.

In a double-layer concentric-wound armature winding for a dynamoelectric machine, the number of slots per phase per pole is set at q. The armature winding comprising a winding which corresponds to one pole and which includes a plurality of coils having different coil pitches from one another. The coils include at least one coil having the number of turns different from those of the other coils. The number q is set at or above 3. The number of coils in one winding is set at (q-n) where n=1, 2, . . . and q-2. The coils are distributed in the slots so that a double-layer, concentric-wound winding resulting in a sinusoidal distribution of magnetomotive force is formed. In another arrangement, the number of pole windings per phase is half of the number of poles in a double-layer concentric-wound winding or a lap winding. The number of coils in one of the pole windings is set at (2x(q-n)).
