TWO-INPUT WIND-SOLAR AXIAL-RADIAL ELECTRIC MACHINE-GENERATOR Russian patent published in 2019 - IPC H02K16/04 H02K19/16 

FIELD: electrical engineering.

SUBSTANCE: invention can be used in converter of mechanical energy of rotation, for example wind energy supplied to mechanical input of machine, and electric energy of direct current, for example, light energy of the Sun, converted by photoelectric converters into DC power, simultaneously supplied to its electric input, into total electric energy of alternating current. Two-input wind-solar axial-radial electric machine-generator contains housing, fixed axis, hollow shaft fixed in housing in bearing assemblies, internal axial magnetic core with two active end surfaces, exciter consisting of rigidly fixed in housing constant axial multi-pole magnet and multiphase winding of exciter armature, laid in slots of internal axial magnetic conductor with two active end surfaces, and main generator, consisting of main main-circuit single-phase excitation winding, laid in slots of internal axial magnetic core with two active end surfaces and connected through first multiphase double-wave rectifier to multiphase winding of exciter armature, and rigidly fixed in housing of side axial magnetic core with one active end surface, in slots of which is laid multiphase armature winding of main generator, wherein internal axial magnetic core with two active end surfaces is rigidly connected to hollow shaft by means of disc, main single-phase excitation winding of main generator is laid in slots of internal axial magnetic core with two active end surfaces on side of side axial magnetic core with multiphase armature winding of main generator, multiphase winding of exciter armature is laid in slots of internal axial magnetic conductor with two active end surfaces on side of exciter inductor, and the fixed axis is located coaxially with the hollow shaft, having the possibility of rotation around the fixed axis, is fixed in the bearing assemblies installed in the hollow shaft, and rigidly connected to housing by one end located on housing side, on which side axial magnetic core with multiphase armature winding of main generator is fixed. In upper part of housing there is a photoelectric converter, and in body there additionally installed is a sub-exciter consisting of radial magnetic conductor of sub-exciter, rigidly fixed on fixed axis, in which slots there is a single-phase excitation winding of a sub-exciter connected to a photoelectric converter, a radial magnetic conductor of an exciter of a sub-exciter, in which slots there is a multiphase winding of an anchor of a sub-exciter, and an additional single-phase excitation winding of the main generator, connected through a second multiphase full-wave rectifier to a polyphase winding of the subarcinot armature and laid in slots of the internal axial magnetic conductor with two active end surfaces on the side of the side axial magnetic conductor with polyphase winding of the armature of the main generator, wherein the radial magnetic core of the subarial armature anchor is installed on the inner surface of the hollow shaft so that the magnetic flux created by the single-phase excitation winding of the sub-exciter is directed along the radius of the radial magnetic conductor of the anchor of the sub-exciter with polyphase winding of the subarcinister armature.

EFFECT: technical result is simplification with simultaneous conversion of obtained total energy into electric energy of multiphase alternating current with simultaneous preservation of magnetic properties of electric machine generator inductor, improvement of energy and mass and dimensions parameters of electric machine-generator.
