FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used in converter of mechanical energy of rotation, for example, wind energy supplied to mechanical input of machine, and direct-current electric energy, for example solar energy, converted by photoelectric converters into DC power, simultaneously supplied to its electric input, into total electric energy of alternating current. Two-input two-rotor wind-solar generator comprises a housing, a shaft, an inductor consisting of a permanent multi-pole multi-section magnet with slots and an excitation winding, laid in slots between sections of a permanent multiple-pole multi-section inductor magnet and connected to a direct current source, and axial magnetic core with one active end surface, in slots of which multi-phase armature winding is laid. Constant multi-pole multi-section magnet of inductor is rigidly fixed on shaft by means of rear disc provided with ventilation openings. In housing of wind-solar generator there are ventilation holes and hollow shaft is additionally installed, on inner end of which axially magnetic core with one active end surface is rigidly fixed. Hollow shaft is fixed inside rigidly installed in housing of wind-solar generator of combined bearing support, consisting of housing with two landing chutes, in which there are ventilation holes, and two ball bearings, inner rings of which are combined with hollow shaft and are made in the form of chutes located on external side surface of hollow shaft opposite to landing grooves of housing of combined bearing support, in which external rings of ball bearings are fixed. Excitation winding is placed in slots between sections of permanent multiple-pole multi-section magnet of inductor on side of axial magnetic conductor with one active end surface. Multiphase winding of armature is laid in slots of axial magnetic conductor with one active end surface on side of constant multi-pole multisection magnet of inductor. An external wind wheel is secured at the end of the hollow shaft extending beyond the housing of the wind-solar generator. An inner wind wheel is secured at the wind-solar generator shaft end extending beyond the wind-solar generator housing. Shaft of wind-solar generator and hollow shaft are made with possibility of rotation relative to each other and relative to housing of wind-solar generator around their common axis of symmetry. Shaft of wind-solar generator is fixed inside hollow shaft by means of front and middle bearings installed inside front and middle disks, made with ventilation holes and fixed inside hollow shaft, and in housing of wind-solar generator by means of radial-thrust bearing, near which on shaft two side current-collecting rings are fixed, connected to excitation winding. Opposite them in housing of wind-solar generator there installed are two sliding contacts connected to horizontal current-collecting rings, which are located in lower part of housing and are made in the form of concentric circles. In the middle part of the outer side surface of the hollow shaft there installed are internal current-collecting rings by the number of phases of the multi-phase winding of the armature which are connected to its phases. Opposite these collector rings there are sliding contacts on the rod-holder, which are connected to horizontal current-collecting rings.
EFFECT: minimization of deviation of wind-solar generator output voltage from wind speed and wind velocity, decrease in weight and dimensions of wind-solar generator.
