ABSTRACT:
An improved alternating current machine having interdispersed armature windings is disclosed. The AC machine comprises an armature core having a plurality of generally longitudinal slots and a plurality of winding groups. Each of the winding groups comprises a plurality of one-turn coil windings which are series connected to electrically adjacent windings of the winding group. Each winding has two generally parallel side portions disposed in non-adjacent ones of the slots. The side portions are joined at one end by an end turn which extends axially outward from one end of the armature core and each of the side portions have an end connection extending a distance axially outward from the other end of the armature core for connecting to a respective electrically adjacent end connection of its electrically adjacent winding. The winding groups are interdispersed about the armature core such that there are a plurality of fixed distances between the electrically adjacent windings. The end connections extend outwardly from the armature core a plurality of distances, and the distance which each particular one of the end connections extends is proportional to the distance between the particular end connection and its electrically adjacent end connection to which it is series connected.
