SINGLE-PHASE GENERATOR WITH ANNULAR ARMATURE WINDING Russian patent published in 2014 - IPC H02K21/16 H02K21/12 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering and design of electrical machines, particularly single-phase alternating current generators. The technical result achieved by using the present invention is considerably high efficiency and improved electromechanical properties of single-phase generators. Said technical result is achieved due to that in a single-phase synchronous generator with an annular armature winding, consisting of an armature and an inductor, separated by an air gap, according to the invention the armature consists of two series-connected annular windings with semi-annular ferromagnetic cores, the nearest rectangular ends of which are attached by nonmagnetic bushings, and the inductor consists of a central cylindrical core mounted on a rotating shaft, wherein on diametrically opposite surfaces of the core there are two rod-shaped permanent magnets with concave like poles. During operation of the generator, turns of the annular windings are penetrated by induction field lines of one direction, originating from like poles of the permanent magnets of the inductor.

EFFECT: structure of the armature enables to direct magnetic field lines thereof around a circle and considerably reduces not only active, but inductive resistance armature windings as well.
