SYNCHRONIZED AXIAL TWO-INPUT NON-CONTACT WIND-SOLAR GENERATOR Russian patent published in 2018 - IPC H02K7/18 H02K21/38 H02K16/00 H02K19/38 

FIELD: electrical equipment.

SUBSTANCE: invention relates to electrical equipment, to electromechanical energy converters, and can be used as a converter of rotation mechanical energy, such as wind energy supplied to the machine mechanical input, and DC electric power, for example solar energy, converted by photoelectric converters into direct current electric energy, simultaneously supplied to its electrical input, into the alternating current total electrical energy. Wind-solar generator contains: body, exciter and main generator mounted on the fixed in bearing assemblies single shaft. Exciter consists of the inductor multi-pole multi-section permanent magnet rigidly installed in the body, in which slots the additional single-phase excitation winding is placed between the sections, and multi-phase winding placed into the internal axial magnetic core with two active end surfaces grooves on the inductor multipole magnet side. Main generator consists of side axial magnetic core with one active end surface, into which grooves are placed three-phase armature winding, and single-phase excitation winding, placed from the axial magnetic core side into the internal axial magnetic circuit slots and connected to the exciter armature polyphase winding through the multiphase full-wave rectifier. Side axial magnetic circuit is rigidly installed in the body by means of a disk. Internal axial magnetic circuit is mounted on the shaft by means of a disk between the inductor with additional single-phase excitation winding multi-pole magnet and side axial magnetic core with possibility of rotation relative to the side axial magnetic core with one active end surface and inductor with additional excitation winding multi-pole magnet. Photoelectric converter is connected to the additional single-phase excitation winding, which is configured to be connected to the external photoelectric converter via contacts. Voltage synchronizer consists of rigidly fixed in the body axial magnetic circuit, in which grooves three-phase synchronization winding is laid, and axial multi-pole magnet rigidly fixed by means of a disk on the shaft between the synchronizer axial magnetic core and the side axial magnetic core. Three-phase synchronization winding phase distribution is made matching to the main generator three-phase armature winding phases distribution. Switching unit is installed in the housing lower part and is made with two inputs. Main generator armature three-phase winding is connected to the first input, three-phase synchronization winding is connected to the second input and the output is made with the possibility of connection to the external three-phase alternating current system. Three-phase synchronization winding phases ends are configured to be connected to the same phase ends of the main generator armature three-phase winding via switching unit.

EFFECT: technical result consists in provision of the light energy direct conversion into direct current electric energy with the subsequent summation of the received energy with the mechanical energy of rotation with the received energy simultaneous conversion into AC electric energy and minimization of the frequency difference of the synchronized axial two-input non-contact wind-solar generator output voltage and the voltage frequency of the external three-phase AC voltage system.
