Description

Coreless Axial Flow Generator/Engine Rotor and Stator Capable of Rotating in Opposite Directions to Each Other and Its Use

Field Of The Invention

The invention is related to generator/engine units that allow transforming kinetic energy in wind, water, gas, steam and other natural energy resources to mechanical energy and mechanical energy into electricity and use of such generator/engine units.

Background Of The Invention

Generators are devices that can transform mechanical energy into electricity. Engines are devices that can transform energy in any form into mechanical energy. Engines and generators are identical in terms of internal parts. In conventional generator/engine applications electricity is generated by means of a rotor and stator. Rotor is a rotating part inside the generator/engine, which is generally structured around an axle or a shaft. Stator is the name of the fixed part inside the generator.

In current art, generators used generally have a single rotor and a single stator. In current art; generators cannot generate any power under a certain wind speed or fluid pressure. Power generation takes place after a certain level and increasing the power capacity can be possible by extending the rotor diameter only.

In current art, rotor in generators is generally formed by placing silicon sheet metals one on another and packing them. In this type of generators rotational magnetic field can only be obtained by reaching to high rotation speeds only. In the generator mentioned, a gear box (reducer) is used for reaching high speeds. Each gearbox used for increasing the rotation speed causes efficiency losses reaching to 25% in systems such as belt-pulley system etc. This efficiency loss decreases system efficiency.

In the patent document with the code of WO2016114680 available in current art, an electricity generator that contains a rotating stator is mentioned. Such generator contains a stator that rotates in the opposite direction of the rotor in order to generate electricity from renewable resources such as wind and water. It also contains a gearbox for increasing the number of rotations. Two blade groups that rotate in opposite directions ensure rotational movement of the rotor and stator. Rotational magnetic field is obtained not with a stationary magnet but with rotational movement. Therefore rotational magnetic field cannot not be obtained without exceeding a certain rotation speed and therefore power generation does not start. Core losses take place since a core formed by pressing silicon sheet metals are used inside the coil. Eddy loss and hysteresis core losses cause heat in extremely high temperatures and therefore efficiency decreases significantly.

In the patent document with the code of CN102299574 available in current art, an axial flow electricity generator is mentioned. In this axial flow generator that is designed specially for use in wind turbines, the stator is stationary and rotor is mobile. There is no stator and rotor that move in opposite direction to each other. The rotor is composed of a magnet and a magnet holder plate. Magnets that are attached on the magnet holder plates by performing an adhesion operation only, may get heated and detach from its place in high rotation speeds.

In the patent document with the code of US20090167027 available in current art, an electricity generator is mentioned. This generator is not an axial flow generator. Magnets are located on sides of the coils. Magnetic flux path is long. Efficiency is low. Core losses take place since a core is used inside the coil. Eddy loss and hysteresis core losses cause heat in extremely high temperatures and therefore efficiency decreases significantly. Magnetic field originating from the North (N) pole passes through the coils at first, at then through the metal core and completes magnetic flux path by reaching to south (S) pole of the magnet. Magnetic flux path here is long. Since magnetic flux path is long, losses increase and efficiency decreases.

In the patent document with the code of KR100928433 available in current art, a moped that is also capable of serving as a power generator is mentioned. In this system used in bicycles, power generator and the engine driving the bicycle movement are used in the same assembly. In this application generator coils and engine coils are separate. Using a generator as an engine is out of question.

In the patent document with the code of US20120148403A1 available in current art, an electricity generator that contains a rotating stator is mentioned. Such generator contains a stator that rotates in the opposite direction of the rotor in order to generate electricity from renewable resources such as wind. Two blade groups that rotate in opposite directions ensure rotational movement of the rotor and stator. Rotational magnetic field is obtained not with a stationary magnet but with rotational movement. Therefore rotational magnetic field cannot not be obtained without exceeding a certain rotation speed and therefore power generation does not start. Core losses take place since a core formed by pressing silicon sheet metals are used inside the coil. Eddy loss and hysteresis core losses cause heat in extremely high temperatures and therefore efficiency decreases significantly.

Objective of Invention

The generator/engine developed for realizing mentioned objectives contains at least one stator (5) that rotates in the opposite direction of at least two rotors (4) and rotor shaft (13), that is capable of rotating like a rotor (4), that contains coil (16) wires inside of it and surrounded by a melting resistant plastic derivative raw material such as polyurethane polyester etc. The generator/engine has at least one brush (8) and a ring (9) for drawing the flux induced in stator (5). There is a jacket (11) that contains insulating oil on the outer part of the brush (8) and the ring (9). It is a coreless and axial flow generator/engine (1). On the other hand it contains a battery, voltage regulator, charging device, driver circuit, slope sensor (25), electronic control circuit (27), shaft (33), revolution sensor (34) and a magnet slot (17), where magnets are fitted on the rotor (4).

The invention is related to generator/engine (1) units that allow transforming kinetic energy in wind, water, gas, steam and other natural energy resources to mechanical energy and mechanical energy into electricity and vehicles using such generator/engine (1) units. It is also related to vehicles containing electric, hybrid and internal combustion engines that can use the same generator/engine (1) as an engine manually and/or automatically.

Generator/engine (1) contains at least one stator (5) and minimum two rotors (4) and each of them is arranged on the same axis. Stator (5) is capable of rotating just like a rotor (4). Stators (5) rotate in the opposite direction of rotors (4). Thanks to rotors (4) and stators (5) rotating in opposite direction to each other, it can generate two time more power than generator/engines (1) with a rotating rotor (4) only and obtain more than times higher efficiency from the same energy.

While the invention transforms kinetical energy received outside to electricity when it is used in wind, water, gas, steam turbines or automobiles; it is capable of generating the amount power that can be generated with full speed in current art application with half speed. For example; power that can be generated with wind speed of 10 m/s in current art in generator application, can be generated with wind speed of 5 m/s thanks to the invention.

The generator/engine (1) can be used in both engine mode only and in generator mode only for generating electricity. Examples of application inside the vehicle are given in Figure 3 and Figure -4. As it can be seen from Figure-3 and Figure -4, generator/engine (1) is connected to axle shafts between two rear wheels (35). In order to allow the right rear axle shaft (39) and left rear axle shaft (40) to rotate in opposite directions to each other, various mechanisms are used while making connection with wheels (35). While spur gear set is used in one wheel (35) in this mechanism, an annular gear (41) in circular form with notches inside is used in another. Such annular gear (41) is fixed on the wheel (35). Rotational movement is transmitted with the gears at the end pf the axial shaft. Thus, rotational movement in opposite direction to each other can be obtained.

With the coreless axial flow generator/engine (1) that can rotate in directions opposite to each other, which is placed between the right rear axle shaft (39) and right rear axle shaft (40) with connection methods shown in Figure 5 and Figure 6, 4 times more power than conventional generators is generated in generator mode. Rotor (4) of the generator/engine (1) is connected to the right rear axle shaft (39) or left rear axle shaft (40). Stator (5) of such generator/engine (1) is connected onto the right rear axle shaft (39) or left rear axle shaft (40). Energy generated here is received by means of the brush (8) and the ring (9) on the axle shaft and transmitted to heavy current -voltage charge control device (23) or low current-voltage charge control device (28). From such charge control device, it is transmitted to heavy current -voltage regulator (22) and/or low current-voltage regulator (29). From the voltage regulators, it is transmitted to heavy current- voltage battery (21) and/or low current- voltage battery (30) and stored there.

Same generator/engine (1) can be used as an engine or generator only depending on the intention and need. In Figure-2, the generator/engine (1) is located on the shaft (33) that is located between the gearbox (19) between the front wheels (35) and rear wheels (35) and axle gear (20) connected to the rear wheels (35) and functions for transmitting motional energy generated in the engine to the gearbox (19). Here, again a coreless axial flow generator/engine (1) with a rotating rotor (4) and stator (5). In this application, stator (5) of the generator/engine (1) is connected to the shaft (33) coming from the rear outlet of the gearbox (19). The shaft (33) transmitting mechanical energy to the rear axle gear (20) is connected to rotor (4) part of the rear generator/engine (1). Rotational movement from the generator/engine (1) in front part which ensures front drive and rotational movement from rear wheels (35), i.e. the axle gear (20) are in opposite directions. Thus, the rotor (4) and stator (5) of the generator/engine (1) are driven in opposite directions. If intended and needed, this generator/engine (1) can be used as a generator only for power generation. The generator/engine (1) with a stator (5) connected to the shaft (33) from the rear (43) and front side (42) and a rotor (4) rotating in opposite directions to each other can generate 4 time more energy than others. In vehicles where more engine power or more energy generation is needed, multi stage generator/engine (38) or multi stage rotor (4) and stator (5) is used. A brush (8) or a ring (9) is used for drawing the energy generated. Number of brushes (8) and rings (9) increase depending on the number of generators/engines (1). Energy generated received by means of such brush (8) and the ring (9) is transmitted to heavy current -voltage charge control device (28) and heavy current-voltage charge control device (23). Then, the energy generated is transmitted to 12/24 volt low current-voltage regulator (29) and heavy current-voltage regulator (22) from different paths. Finally, they are transmitted to 12/24 volt low current-voltage battery (30) and heavy current-voltage battery (21) and stored there.

When the vehicle becomes four wheel drive, a rotation speed sensor (34) is used for adjusting speed balance between the front wheels (35) and the rear wheels (35). Rotation speed sensor (34) adjusts the signal transmitted to the rear generator/engine driver circuit (24) through the electronic control circuit (27) and ensures that front wheels (35) and rear wheels (35) move with the same rotation speed.

The generator/engine (1) which is positioned on the shaft (33) or can be used between the axles other than those driving axles in vehicles with more than two axles, can be used as an engine only when necessary (at ramp, exhaustion of fuel in hybrid vehicles etc.). Rear generator/engine (1) can be used as an engine only in situations where front side (42) generator/engine (1) or conventional engine (37) breaks down. Gearbox (19) system may lock the mechanical energy, i.e. the rotational movement from the gearbox (19) outlet to the rear axle gear (20). Rotor (4) of the rear generator/engine (1) can be fixed with this locking action. This time, energy is supplied by the batteries by means of the brush (8) and the ring (9) used for drawing electricity when it is generated. Energy supply is provided over the brush (8) and the ring (9) by turning on the electronic switches (32) modulate generator/engine (1) mode connected to the heavy current -voltage charge control device (23) and turning off the electronic switches (32) on the rear engine driver circuit (24). Thus, rear generator/engine (1) functions as an engine only with the energy supplied. Operation of the rear generator/engine (1) as an engine provides drive power to both front wheels (35) and rear wheels (35) of the device. It is possible to shift to all drive mode at ramps with manual all wheel drive shifting button (26) or automatically with the slope sensor (25). Therefore it is possible to stop power generation of the same generator/engine (1) if necessary and intended and use it as an engine. Along with such generator/engine (1), it is also possible to use conventional engines (37). When axial flow generator/engine (1) is used for the front drive, stator (5) of such generator/engine (1) can be fixed on the main frame. The rotor (4) is connected to the gearbox (19) system of the vehicle. When gearbox (19) system is not used, it is transmitted directly to the shaft (33) and axle shafts through axle gear (20) systems in order to transmit mechanical energy to front wheels (35) of the vehicle. Furthermore, same mechanical movement is transmitted to the shaft (33) coming from the front axle gear (20) to the rear part and stator (5) of the generator/engine (1). Its rotor (4), on the other hand, rotates with the motion from rear wheels (35) and rear axle gear (20).

Energy Generation / Rotation Speed Graph

Graph-1

Two separate axial flow generator/engine with identical physical and technical specifications are mentioned In Graph-1. Rotation speed-power graph of an axial flow generator/engine (1) with rotors (4) and stators (5) rotating in opposite direction to each other and an axial flow generator/engine (1) with a rotating rotor (4) only is as shown above. As rotation speed increases, power consumption of both generators/engines (1) increase, too.

Generator/engine (1) with rotors (4) and stators (5) rotating in opposite direction, produces 4 times more energy than the non-rotating one. Because resultant speed of magnetic field and conductors in proportional to each other increases 2 fold. Since power is proportional to the square of speed, electrical power generated is 4 times more thanks to rotation in opposite directions. 4 times more power is generated in comparison to the engine consuming same amount of energy.

The invention can also be used for different purposes in different areas. In case be used either as an engine or a generator or both as a generator and an engine. Examples of various alternative applications are given in figures.

A low current-voltage battery (30) is used for supplying secondary needs of car's interior and exterior such as headlights, radio, interior lighting and air conditioner. High current- voltage battery (21) is used for the energy need for motion, which is the primary need. By drawing 12/24 volt from the cells of the heavy current-voltage battery (21) storing the energy for driving the engine by using two separate battery groups, failure of these cells that will allow feeding from other receivers in the car and complete heavy current-voltage battery (21) is prevented. Therefore battery lives are increased

Power/Torque-Rotation Speed Graph

Graph-2

Torque and power supplied when power obtained from the generator/engine (1) when gearbox (19) system is used and gearbox (19) system is not used is as shown in Graph-2.

In order to prevent generator/engine (1) to consume more energy by reaching high rotation speeds, automatic gearbox (19) system is used. In this gearbox (19) system, motional energy, i.e. rotation speed obtained from the front engine, is transmitted to front drive wheels (35) by means of gearbox (19) gears by not pressing the gas pedal too much, depending on the transmission level. Since the gas pedal is pressed less during this period, less energy is drawn from heavy current- voltage battery (21).

As the gearbox (199 system is considered as a huge load for the vehicle, it is not preferred using in electrical vehicles. Engine or engines with rotation speeds adjusted by means of an electronic control and software, as no gearbox (19) system is used, draw more energy from the battery in high rotation speeds. Efficient used of energy is aimed by using a gearbox (19) system along with increasing energy production in vehicles. It becomes a vehicle that can use coreless axial flow generator/engine (1) with a rotating rotor (4) and stator (5) with gearbox (19) system. On the other hand, range of the vehicle increases since 4 times more power is generated when compared to other generators. Furthermore, there are charging input (36) where both batteries are connected, in order to allow energy intake externally.

Lower Cover (6) and top cover (3) protect stators (5) and rotors (4) from external factors and ensure fixing of rotors (4). Lower Cover (6) and top cover (3) contain a ball bearing from facilitating the rotational motion and ensuring balanced movement of the shaft.

Stator shaft (7) passes through the bearing on the top cover (3) or lower cover (6) and connected to the stator (5). Stator shaft (7) and rotor shaft (13) rotate in opposite directions in proportion to each other. Top rotor (4) is fixed on the top cover (3) and lower rotor (4) is fixed on the lower cover (6). Lower Cover (6) and top cover (3) are fixed to each other from the screw travels (14) in a manner that stator (5) movement is not inhibited. Therefore the rotors (4), which are symmetric to each other can move together.

Stator (5) is the part where the energy is induced and coil is located. There are two phase outlets (2) to draw voltage induced in the stator (5). Number of phase outlets (2) varies depending of the number of stators (5). Since the energy is induced at stator (5), a brush (8) and a ring (slip ring) (9) is needed to draw voltage outside. The brush (8) and the ring (9) are located on the same axis with the rotor (4) and stator (5). Stators in current art are made of insulated silicon sheet metal packing. However in stators (5) formed with insulated silicon sheet metal packing, no magnetic field can be created without exceeding a certain rotation speed if there is no magnet (15) rotor. In order to keep coils (16) forming the stator (5) together, insulating and melting resistant plastic derivative raw materials such as polyurethane, polyester etc. are used instead of pressed silicon sheet metals.

Coil (16) is obtained by using and winding varnished coil windings or similar conductive coil materials other than copper. In order to benefit from the circular section of the generator/engine (1) at the maximum level and to obtain more power from the dame circular volume without expanding external dimensions of the generator/engine (1), it is necessary to place more coil winding and magnet (15) inside available volume. Therefore coil (16) windings and magnets (15) are prepared in trapezium form. Connection between the coils (16) is ensured with soldering after completing the winding operation. After soldering operation, a tube is placed on soldered points for ensuring insulation. After that, coils (16) are varnished for preventing occurrence of any short circuit incidence. Coils (16) are placed into the mould following varnishing and insulation operation performed preferably with a plastic derivative raw material such as polyurethane, polyester etc. Coil (16) end are exposed for phase outlet (2) during moulding operation. Exposed coil (16) ends are insulated with tubes and taken outside. These coil (16) ends where the voltage is drawn are called phase outlets (2). Phase outlet (2) is taken outside of the generator/engine (1) with the brush (8) and the ring (9). Spark occur in the brush (8) and ring (9) in high rotation speeds. In order to prevent spark formation, the brush (8) and ring (9) are covered by a jacket (11). In order to prevent sparking that takes place when the generator/engine (1) reaches to high rotation speeds, insulating oil is used inside this jacket (11) area. On the other hand jumping of sparks between rings (9) is prevented by using compartments (10) between the rings (9).

Coil (16) windings can be wound as a single layer with thick winding. Along with that, it can be wound as multi layer by using a thinner coil (16) winding in order increase coil capacity and filing the gaps. Here, coil (16) winding tips are connected in parallel to each other for every coil (16) winding and thus created a single tip. Then, these star or delta connection is made with these tips depending on the choice and they are taken outside according to desired number of phases.

Rotor (4) is generally the name used for the rotating part in the generator/engine (1). In large generators/engines (1), coils (16) may also be placed in rotor (4). Rotor (4) is composed of a magnet (15) and a magnet holder plate (12). Magnet holder plate (12) is made of materials with high Gauss values. Thickness of the magnet holder plate (12) and the magnet (15) is same. If the magnet holder plate (12) is thicker than the magnet (15), its weight will increase and there will be more load on the rotor (4). If it is thinner, magnetic flux will not flow sufficiently and magnetic saturation will take place.

Neodymium series magnets (15) are used in the rotor (4). Thanks to the neodymium series magnets (15) used in the rotor (4), it continuously creates its magnetic field and starts to generate electricity in low rotation speeds. There are magnet slots (17) where magnets (15) can fit completely on the magnet holder plate (12). These slots are smaller than 1 millimeter and thin enough for not disabling magnet (15) poles. Such slots are very thin slots that do not expose magnets (15) to centrifugal moment arising from the rotation when adhesive is applied inside and ensure easy placement of the magnets (15). Magnets (15) are attached on magnet slots (17) that vary depending on the size of the magnet (15) we use. A special adhesive is used for bonding magnets (15). As the distance between the magnets (15) becomes shorter, more magnets (15) are accommodated inside the circular volume and thereby magnetic field increase is achieved. Furthermore, number of magnets (15) on rotors (4) around each stator (5) is equal.

Number of magnets (15) of the rotor (4) and number of coils (16) on the stator (5) are determined based on a certain ratio. This ratio is determined as three coils (16) for every four magnets (15). Risk of eliminating magnetic fields created, in other words the risk of elimination of directional electromotor forces induced by magnets (15) in coils (16), is prevented thanks to this ratio.

Silicon sheet metals are used in stators of conventional engines (37). Electromotor force is induced in conductive materials moving inside the magnetic field. According to this principle, silicon sheet metals are induced electromotor force i.e. a certain voltage. However such voltage is short circuited by the sheet metal and therefore core and thermal losses take place. This situation decreases general efficiency. In axial flow generator/engines, insulating plastic derivative raw materials such as polyurethane, polyester etc. are used instead of silicon sheet metals. Therefore these kinds of losses are eliminated.

A single line magnet (15) is used in conventional engines (37). Therefore it takes long for the magnetic flux created to complete its path. Magnetic flux exiting from the rotor (4) completes the path in the magnet (15) near it by following a U-shaped path. Efficiency decreases and magnetic flux path becomes longer. Since two rotors (4) are used in axial flow generators/engines, flux exiting from the first rotor (4) will be completing its path at the rotor (4) located just opposite of it after having induced by electromotor force in coil winding between them.
