DETAILED DESCRIPTION EMBODIMENTS OF THE INVENTION

The U.S. Provisional Patent Application No. 62/762,427 for “Alternator used the graphene wire winding for reducing sizes and weights for multi-purpose applications” filed on 3 May 2018 is incorporated by reference herein for any and all purposes.

Alternator and generator produced for the past 300 years has used 100% of a single copper wire for winding the electric rotors and stators for producing electric power, and the single copper wire portion has been about 60% and the steel portion about 40% for the housing and shafts.

The copper has limited production, and the price has been raised 3 times in the past 10 years.

When using 100% copper of heavy weight, the alternator or generator also must use heavy steel for the housing and shafts.

In the present invention, copper wires are replaced with ultra-strong graphene wires, and the steel housing and shaft are replaced by newly discovered material of GIGA-Steel (by POSCO(R) steel company), which is 2 times lighter, and 5 times stronger, and 2 times cheaper than Titanium, which will reduce about another 30% of weight. The total reduced weight by about 80-90% is amazing, and it creates revolutionary economic benefits to the world industries.

Producing more kilowatts means using more heavy copper wires equally, and therefore entire sizes and weights get also bigger gradually with Kilowatts.

For an example, in 2015, we tested 1.1/2 MW alternator, and it has 10,000 LBS (5 tons) required 1500 HP with 1800 RPM. It it needs 10-tons folk lift for handling this alternator.

With the present invention, 10,000 LBS of the alternator can be reduced to 1,000 LBS, and it might be used by 300 HP with speed up to 4000 RPM. For the new system is about 80-90% lighter than the conventional ones and it has higher electrical conductivity.

Therefore, the present invention can produce from a small size alternator to a power plant scales (5 KW-3 MW).

The present invention may be operated by a human power, and not requires high horse power(HP). Also the speed RPM can be raised more than double, due to lighter weights and a high electrical conductivity of the graphene wire windings.

So besides economic benefits, the demand will be exploding world-widely for diverse applications. As known to the community, vehicles and other moving objects have limited spaces and can not be equipped with higher weights and sizes of alternators, especially in the small electrical vehicles, helicopters, drones, etc.

The present invention especially provides two side long shaft for an alternator or generator.

The present invention teaches how to use two side rotating shafts pacifically for alternators or drones.

As shown in FIG. 5, an alternator or generator may includes a DC motor (900) powered by a battery (500) and two alternators (200) on both side of the long shaft. The alternators rotate together with the same RPM as the DC motor (900), and use wasting energies when rotating, and store the generated energy in another energy storage such as battery, capacitor, or grid.

Also as shown in FIG. 6, a drone includes normally 4-6 blades or wings. In the illustrated embodiment, only two wings are shown for clarity.

As in FIG. 5, the alternators (200) are installed on one end portions of the long shaft (800) and rotates along with DC motors (900) of the drone. The energy harvested by the alternators (200) may be used to power the DC motors (900) or to store in energy storing devices (500, 600).

The above two examples show how to get the enough electrical power. The drone having a two side long shaft of motor or alternator can be provided with one for top motor wings, and the bottom side is newly attached with an alternator or generator rotating together at same RPM as the motor wings, and the produced power can be recharged to the batteries or used for the motor power directly.

Those system can be attachable 2 to 6 alternator/generator under the wing motors when needed. That means new drones can fly for an extended time period, and it is possible to use as a military drone, Electrical Helicopter, or small air planes for manned or unmanned applications, because the total system is super lighter and of compact sizes, and the alternator/generator produces electrical power as much as needed, so as to design power specs as required.

Conventional alternators or generators have not been used frequently and widely because the sizes and weights are not fitting within the vehicles so it becomes useless patents unexpectedly.

The applicant's graphene-related U.S. Pat. No. 8,269,401 issued on Sep. 18, 2012, U.S. Pat. No. 8,536,760 issued on Sep. 17, 2013, and U.S. Pat. No. 8,519,596 issued on Aug. 27, 2013 provide a system that is not enough to produce electric power as required by industries.

The present invention is how to produce high electrical power, and reduce size, weight or sound pollutions on an alternator economically.

The graphene wire is more flexible and ultra-strong than steel, and it has a higher conductivity than copper wires, the efficiency is double compared to copper, which means the power recharging time to the battery is unbelievably faster than current 100% copper wire wound conventional alternators or generators.

The most important question is how to get the graphene wires that have never been used in the industries.

The present invention is to use graphene wires for producing electrical power as following patent application and the published articles: (1) electrical cable' ACS Nano, 12, 2803-2808 (2018) Graphene electrical cable/wires Developed By Seoul National University; and (2) U.S. patent application Ser. No. 13/311,376 (Dec. 5, 2011) for “Graphene electrical wire and a method for manufacturing” by Kim Ki Il, Young Kim, Sang Woo Kim.

The present invention presents new tied and twisted graphene wire/cable for producing more electrical power and improving winding methods. The conventional alternator, generator, and motor have used a single copper wire for the past 3 centuries.

The copper wire is thicker and heavy, and has a low conductivity. Therefore, it cannot be used in forms of tied wire or twisted wire for the rotor or stator winding.

The graphene wire can be smaller than human hair in size and mass.

Since it is not physically feasible to wind a single wire itself, the device in this invention uses at least two or more tied wire or twisted graphene wires before or after chemical vapor deposition (CVD) or Electroplated of outer layer for better winding and increasing power generating rate. The graphene wire is at least 10 times more strong and having higher electric conductivity than single copper wire.

For example, winding of 3 graphene wires twisted 1000 feet can produce 3 times more power than winding of single copper wire 1000 feet. So it is greatly different in the efficiency and economic benefits.

Furthermore, in the present invention, the graphene wire power output is extended and connected to at least one of a rechargeable batteries, a power storing capacitor circuit or a power motor for transmitting 100% of electrical power directly “as an option”. Generally most of alternator output connectors are reconnected to the other copper wires, and the copper wire has at least 10 times lower electrical conductivity than graphene wires. Therefore, it is recommended to uses by original Graphene wires without switching to other single copper wire.

Recently, quick charging graphene batteries and high power storing graphene capacitor have been developed that will support for this graphene alternators greatly.

The present invention is also how to removing high thermal heat conductivity, because the graphene tube or sheet has high thermal heat conductivity as well as high electric conductivity, but that thermal heat conductivity is removed while processing the graphene wires technically (Technical information not disclosed).

The present invention of super compact size, weight and conductivity of graphene alternator can be adapted for all purpose of power generating applications and attach able to vehicles, moving objects and equipment without hesitating of sizes, weight and sound pollutions worries that problems is now resolved hereafter.

Reference will now be made in detail to embodiments, example of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. In this regard, the present embodiment may have different forms and should not be construed as being limited to the description set forth herein.

Accordingly, the embodiments are merely described below, by referring to the figures, to explain aspects of present description.

The specs of alternator is determined by factors such as Voltage, Kilowatts or speed RPM etc. The specs will be fixed before installing the electric rotor and stator in a housing, and most of other parts are reusable and remain same. The rotor is permanently installed on a rotating shaft, so it will be rotating together with shaft when operating moving objects.

The graphene wire winding of the electric stator is secured with housing and not allowed rotating while operating moving objects, and the graphene winding rotor is attached to the shaft, it rotates together freely and uses brushless alternator.

The electric rotor can be installed directly on a rotating shaft of the alternator independently for self producing electrical power or attachable to the main shaft or driving shaft on vehicles or other moving objects when receiving custom orders then in this case, that can be used wasting energies of rotating shaft of the vehicles or other moving objects without connecting gears, belts, or chains. That is why industries required small sizes and light weight of alternators for using wasting energies from the vehicles, moving objects and equipment, the system not required separate energy when attaching to the shafts of vehicles or moving objects.

Referring FIG. 3 is simple drawing of stator showing winded graphene wire (30) for better understanding.

Referring to FIG. 5 is a power generating system harvesting energy from a two side long shaft The DC motor (900) is powered by a rechargeable battery (500) and rotates the long shaft (800), and two graphene alternators (200) are installed at both ends of the long shaft. The output from one of the two alternator (the right one in the illustrated embodiment) may be directed to the DC motor (900) directly or to the battery (500), and the output from the other alternator (200) (the left one in the illustrated embodiment) may be directed to charge another battery (600) to be used later.

The output from one of the two alternators (200) may be directed to the DC motor (900) directly or to the battery (500, 600) to be charged and used later.

Referring to FIG. 7 is a schematic diagram of graphene coil winding apparatus according to the present invention. The frame (3) I attached to a platform (2) of a graphene coil winding apparatus (1) at each end, a spindle (5) being supported by this frame (3). The spindle (5) is joined to a spindle motor (6) through the frame (3), and a jig (5A) is provided at one end of the spindle (5) so that a bobbin (4) can be freely attached and removed. The bobbin (4) has a flange at end, and a wire (7) is wound around the bobbin (4) between these two flanges.

The spindle (5) rotates together with the spindle motor (6) and when the bobbin (4) rotates due to the rotation of the spindle (5), the graphene wire (7) supplied from a nozzle (8) is wound around the bobbin (4).

The winding apparatus (1) is further provided with the nozzle (8), a tension device (9), and a spool (10(a), 10(b), 10(c)), the wires (7) is wound around the bobbin (4). The tension device (9) maintains the tension of the wires (7), which is fed out from the spool (10(a), 10(b), 10(c)) on which the wires (7) is stored to the nozzle (8), at the fixed level.

The winding apparatus (1) of the present invention further comprises a first traverse mechanism (11) and second traverse mechanism (15) which displace the nozzle (8) parallel to the axis of the spindle (5).

Then first traverse mechanism (11) is attached to the frame (3). The first traverse mechanism (11) comprises a first traverse motor (12), a first traverse shaft (13) which is joined to the shaft spindle (5), and a first base (14) which displaces along the first traverse shaft (13). The first traverse shaft (13) is a screw shaft having a screw thread on its outer circumference. The first base (14) has a screw hole into which the screw thread of the first traverse shaft (13) screws. When the first traverse motor (12) rotates, the first base (14) is displaced along the first traverse shaft (13).

The second traverse mechanism (15) is attached to the first base (14). This second traverse mechanism (15) comprises a second traverse motor (16), a second traverse shaft (17) which is joined to the second traverse motor (16) and disposed parallel to the first traverse shaft (13), and a second base (18) which is displaced along the second traverse shaft (17).

As in the case of the first traverse mechanism (1), in the second traverse mechanism (15), the second traverse shaft (17) is a screw shaft having a screw thread on its outer circumference. The second base (18) has a screw hole into which the screw thread of the second traverse shaft (17) screws. The second base (18) is displaced along the second traverse shaft (17) due to the rotation of the second traverse motor.

According to this embodiment, the nozzle (8) is fixed to the second base (18) of the second traverse mechanism (15). Therefore, when the first traverse motor (12) of the first traverse shaft (13) rotates, the first base (14) is displaced, the second base (18) of the second traverse mechanism (15) which is attached to this first base (14) is displaced together with it, the nozzle (8) performs a traverse movement parallel to the spindle (5), and the position of the nozzle (8) relative to the bobbin (4) changes.

Likewise, when the second traverse motor (16) of the second traverse mechanism rotates, the second base (18) is displaced. The nozzle (8) performs a traverse movement.

These traverse movement of the nozzle (8) can also be performed simultaneously while the traverse motors (12 and 16) are rotated.

The first traverse mechanism (11) displaces the second traverse mechanism (15) and the nozzle (8), so a large, powerful motor is used for the first traverse motor (12).

The first traverse shaft (13) has a large diameter, and it has a screw thread having a large pitch.

The present invention of graphene wire winding apparatus provided a third motor (20) and also provided a rotating table (30) for winding two or more graphene wires winding that can be set at lease two or more spool of (10(a), 10(b), 10(c)) on a rotating table, in the past 3 centuries it has been used single copper wire for the alternator, generator, or motors.

This present invention shows how to make two or more wire tied and twisted wire winding, when motor rotating slowly it produces tied wire, and increasing speed of RPM, it produces twist wire.

The graphene wire is lightest and strong material, so it can be used even 10 wire in a winding machine.

FIG. 8 is a block diagram showing control system of the winding apparatus.

Winding apparatus comprises a controller (19) which comprises, for example, a computer.

Information required to perform winding is input to the controller (19), and the controller (19) controls the rotation of the spindle motor (6), first traverse motor (12), and second traverse motor (16), and the turn table motor (20) on based on this information.

To start winding the controller (19) first rotates the spindle motor (6), controls the rotation of the second traverse motor (16) based on a preset diameter of the wire (7), and displaces the nozzle (8) in the axial direction of the bobbin (4) by a distance corresponding to the diameter of the wire (7) for each rotation of the bobbin (4). After the nozzle (8) has displaced a predetermined distance between the flanges of the bobbin (4), the rotation direction of the second traverse motor (16) is reversed, and the nozzle (8) is displaced in the reverse direction. The number of these back and forth movement is determined according to the member of layers to be wound on the bobbin (4).

The motor (20) (M3) is also controlled by controller (19), when winding two or more graphene wire, a single wire can be used without rotating turn table (30).

When winding is finished, the controller (19) stops the spindle motor (6), and stops the rotation of the second traverse motor (16). Next, the rotation of the first traverse motor (12) is controlled so that the nozzle (8) is displaced to a position where is does not interfere with removal of the old bobbin (4) and fitting of new bobbin. After the new bobbin (4) has been attached, the nozzle (8) is controlled to return to its initial position.
