Description

INVENTION NAME:
ELECTRIC GENERATOR WITH ROTATING STATOR AND APPLICATION
INVENTOR: Zoran Bogdanovic fromNis, Episkopska street no. 62
Technical Field
The invention belongs to the field of electronics.
According to international classification it has the designation: .
Technical problem
The lack of electric energy is the global problem in it continually grows. Combustion of fossil fuels is adverse and the stocks are about to end.
It is expected that the electric energy, as driving energy, will take control which is now kept by fossil fuels.
The global technical problem is insufficient production of electric energy from renewable resources.
Background Art
The existing electric generators, except for photovoltaic cells, give the energy that is induced by rotating motor while the stator is at rest. The rotation of the rotor and the quantity of produced energy is conditioned by the force which is transferred to the rotor axis from the propellers of wind generator or from the blades of hydro generator's turbine or generator driven by aerated water.
I order to provide enough force to move the rotor of electric generator the development of expensive wind generators, hydroelectric power plants with dams, thermal power plants or nuclear power plants is necessary.
Wind generator may be buDt only on places that are windy enough Hydroelectric power plants may be built only where there is enough fossil fuel or enough water for nuclear reactor cooKng.
The aforementioned conditions for the development of power plants restrict to a great extent the locations for the production of electric energy.
Description of solution of technical problem
The solution of global problem is in the increase of possible locations for the production of electric energy and in the reduction of the costs of power plants development ad in the optimization of existing by replacement of current electric generators with the new, more efficient types - stated here.
These constructive solutions enable the production of electric generator with the rotating stator. The rotating stator is moved by the special axis that is rotating in the opposite direction from the rotating direction of the rotor axis. Such electric generator may function with the half of previously needed force and enables the duplication of locations for the production of electric energy from naturally renewable resources.
Brief Description of Drawings
Figure 1
Housing of electric generator (1) contains of two parts connected by appropriate bolts (33 and 34), over bearings (5,6,9 and 10) provides the desired body position of rotating stator (2) and rotor (3).
Necessary gearboxes (17, 18 and 35) are fixed for the housing (1) of the electric generator.
The housing (1 ) enables a safe connection with the pillar (23), movable base (22 and 31 ) or fixed base
(32).
The collectors are metal rings (7) fixed on the body of rotating stator (2) which by sliding contact over graphitic brushes (8) transmit the induced electric energy out of the electric generator.
In the Figure 1 there is the cross section of the electric generator with the rotating stator (2) and one-sided axis entrance (13 and 14) moved by rotor (3) and rotating stator (2) of the opposite rotations.
There is the relative position of axes (11 and 129 and (13 and 14) as well as the positions of the bearing (4, 5, 6 and 10) placed in the housing of electric generator (1), as well as bearing the (9) laced in the body of rotary stator.
There is the sliding transmission of electric energy from metal rings (7) over graphitic brushes (8) and further through the housing of the generator (1) to the conductor.
Figure 2
Figure 2 shows the cross section of electric generator with the rotary stator (2) where the axes of rotary stator (13) and rotor (14) get into the electric generator from the opposite side and have special transmissions (17 and 18). Of mutually opposite rotations, each axes moves its own part of generator. There is the mutual position of rotor (3) and rotating stator (2) and the position towards the housing of the generator (1) secured by the appropriate bearing (4) of the end of rotor axis (14) placed in the body of rotary stator (2) as well as the appropriate bearings (5, 6, 9 and 10) placed in the body of housing of electric generator
There is the sliding transmission of electric energy as in the Figure 1.
Figure 3
Figure 3 shows the wind generator with rotating stator and with two groups of propellers. Three- bladed propeller (20) which turns the axis (12) of the rotor (3) has the opposite director of turning from the direction of turning of the three-bladed propeller (21 ) which moves the rotating stator (2). The housing of the electric generator (1) is screwed for the base (22) which is turning so that the propellers (20 and 21) could receive the best wind.
The base (22) is on the top of the pillar which is not showa
Electric energy transmission, by sliding contact, is the same as in the previous descriptions.
Figure 4
Figure 4 shows the vertical wind generator with the electric generator in the Figure 1 moved by sails (24, 30...) made of tighter panel or some light but strong enough material For functioning of this type of wind generator two groups of sails are needed with three or four sails in a group. The Figure shows two groups of sails with two sails on each for the clear picture.
The upper group of sails turns the axis of the rotor (3) and lower group of sails turns the rotating stator (2). These groups of sails are turning in the opposite directions.
Each sail (24, 30...) under the influence of the wind force, rotates around its axis (25, 36...) and around the axle (11 or 12) which it moves. By its axle (25 or 36) through the bearing (28) into the level (37), it moves the lever (37) which by firm connection turns the rotor axle (12) or axle of rotating stator (11).
At the ends of sail axles (25, 36...) there are gears fixed (26), which are in the direct relation, or over chains, with immovable gears (27, 29...) fixed on the base (23) of the wind generator that dictate the position f sails (24, 30...) in relation to the axle (1 1 or 12) that they turn and to the wind direction. It is important that the number of gear teeth (27, 29...) fixed on the base (23) of the wind generator is double lower than the number of gear teeth fixed on the sail axles (26). Such a relation of the gears enables that the sail (24, 30...), around its axis (25, 36...) turns double slower than around the axle which: over the lever (37) turns the rotor axle (12) or rotary stator axle (11). Such a rotation of sails enables good receipt of wind and all sails from the grou contribute to the axle turning.
Figure 5
Figure 5 shows the horizontal wind generator with electro generator from the Figure 2 moved by the sails (24, 30) similarly as in the Figure 4.
The shown wind generator must be installed on the movable base (31) that will follow the wind direction or over the stabilizer fixed on the wind generator housing (1 ), or on the base of wind generator (31 ) or electromotor adjustment with computer control
Figure 6
Figure 6 shows the hydro generator with electric generator from the Figure 1 moved by the blades (30 and 24) of similar shape as sails (30 and 24) in the Figure 4. 1.
The hydro generator is similar to wind generator from Figure 4. The difference is that the base of hydro generator (32) is set into the horizontal position and it is anchored in the bottom of the water flow and the isolation of electric generator and drain of electric energy must be sufficient.
Figure 7
Figure 7 shows the hydro generator with electric generator from Figure 2 moved by the blades (30 and 24) of similar shape as sails in the Figure 5.
The hydro generator is similar to wind generator in Figure 5. The difference is that the base (32) must be anchored in the bottom of the water flow and the isolation of electric generator and drain of electric energy must be sufficient. Here the stabilizer is not needed.
The hydro generator should be submerged in the water flow in horizontal positioa Anchored in bottom by concrete or metal structures or cables.
Disclosure of invention
With all types of electric generators, stated here, the installation and usage of necessary devices and equipment implies, as with the current electric generator.
The basic innovation of electric generator with rotating stator is the structure that enables the existence and function of rotating stator (2) and classic rotor (3).
With small changes of electric generator and with bringing the electric energy from the network on sliding contacts (7 and 8), we get the electromotor with two drives of opposite rotatioa
Rotating stator (2) has the necessary windings (15 and 16) and function as the previous stator whereas it is not static but rotates in the opposite direction from the direction of rotor rotation (3). The induced energy is transmitted over the sliding contacts (7 and 8) on conductors and out of electric generator. The sliding contacts consist of metal rings (7) that are fixed on the body of rotating stator (2) and the rotate with the stator (2). The metal rings (7) are connected with the windings (15 and 16) from the rotating stator (2) and take over the induced power from the windings (15 and 16), that they transfer to the graphitic brushes (8) and the brushes to conductors.
The existence and proper functioning of electric generator (or electromotor) with the rotating stator is possible only if the stability and firm connection of housing (1) of electric generator with the base (22, 23, 31, 32) is provided.
The housing (1 ), with earlier electric generators, was the body of stator and performed the function of relation of electric generator with the safe base while with the electric generator with rotating stator you need the housing (1 ) that provides the firm relation with the fixed or movable base.
Such a housing (1) must provide also the necessary mutual position of rotating stator (2) and rotor (3). This is achieved by necessary bearings (5, 6, 10) placed in the housing (1 ) of the electric generator in the body of rotating stator (9). On the body of housing (1 ) there are gearboxes fixed (17, 18, 19), that accelerate the rotation of the rotor axle (14) and rotating stator axle (13) to the necessary pace for optimal induction of power. The number and the size of gearboxes depend on the type of electric generator.
The bearings (19) on the ends of bases and parts of bases through which the rotor (12) and rotating stator (11) axles go through, provide the stability of the rotation of axles. The axles rotate under the influence of wind or water force transmitted by the blades or sails.
