ABSTRACT:
An electromechanical machine is disclosed which comprises a field producing assembly mounted in a housing so as to define an air gap circumferentially disposed about an axis of rotation. The field assembly is structured to produce a distribution of magnetic flux in the air gap having P periodic extremes of flux density about the axis. An armature is positioned in the air gap, and mounted so that the armature and field assembly are rotatable relative to each other. The armature has a circular array of C non-overlapping coils on each of its front and back faces, the coils on one face being angularly offset from the coils on the other face and each having the same arcuate extent, smaller than 360 degrees divided by P.
