Abstract
A rotating electrical machine includes a stator and a rotor rotatably mounted on the stator. The stator includes a plurality of slots into which coils are insertable, a plurality of types of unit coils inserted into the slots at slot pitches differing for every type of unit coil, and a plurality of coil groups formed by arranging the unit coils in a lap winding so that the unit coils are overlapped in a radial direction of the stator. The coil groups have the same arrangement configuration before insertion into the slots and are inserted into the slots so as to be shifted from each other by a predetermined slot pitch.
