In one embodiment, the drive gear 14 is connected with the shaft 16 of the rotor by means of a chain or other drive mechanism and configured to move, when to move the shaft 16 of the rotor. Other types of connections the drive gear 14 to the shaft 16 of the rotor and with plenty of engine-generator devices 20 are also acceptable.

In General, the electric motor-generator module 10 includes a shoulder 17 of the rotor or other device that is configured to communicate with a source of energy, such as wind, when used to the maximum extent energy source. In one embodiment, the electric motor-generator module 10, through the vanes 17 of the rotor, configured as shipped by air electric motor-generator module 10. Other suitable devices for use in maximum energy sources include water wheels, blades, cutters and the like. In one embodiment, optional provided by the housing 19 (part of which is illustrated in Figure 1A), enclosing order to protect the installation plate 12, the drive gear 14 and the motor-generator device 20 connected to the mounting plate 12. When the electric motor-generator module 10 configured to maximum use of the wind at high altitudes, provide the fuselage 21, part of which is shown in Figure 1A.

In General, the electric motor-generator module 10 includes a frame, such as the installation plate 12 (or platform 12), and drive gear 14, both of which are connected with the shaft 16 of the rotor (or the main shaft 16 or the shaft 16). In one embodiment, the shaft 16 is formed from non-conductive material and configured to electrically isolate the motor-generator device 20 of the platform 12. In one embodiment, the platform 12 is round or disc-shaped and made of metal, such as aluminum, stainless steel, titanium, composite materials or other materials suitable for air and/or land use cases. Experts in this field agree that the platform 12 may be made of any suitable material based on the target electric d is the " generator module 10. To use maximum energy at high altitudes, in one embodiment, the platform 12 has a diameter of approximately 30 feet.

In one embodiment, the drive gear 14 is connected with the output shaft 24 due to friction or the drive gear 14 or the output shaft 24 does not include teeth.

In one embodiment, the drive gear 14 includes teeth 18, which are configured to interlock with the teeth 22 provided on the output shaft 24. The teeth 18 teeth 22 include spur, helical, herringbone, planetary, bevel straight, spiral or hypoid teeth, and the worm teeth. In one embodiment, the teeth 18 and the teeth 22 of the output shaft 24 include aluminum, stainless steel, titanium, composite materials or other suitable materials.

In one embodiment, the diameter of the drive gear 14 is slightly smaller than the diameter of the platform 12. In other embodiments, the implementation, the diameter of the drive gear 14 is greater than the diameter of the platform 12.

The electric motor-generator module 10 generally includes many motor-generator devices 20 located around the circumference of the drive gear 14. Suitable motor-generator device 20 include any type of electrical DWI is the motor or any type of electric generator, which has a first mode which transforms electrical energy into rotational motion or translational motion, or transforming a rotational movement, or has a second mode that transforms this motion into electrical energy, or works in both modes, or is reversible between the first mode and the second mode. The engine-generator unit includes a separate physical device, or a separate generator device, or a device that includes both the engine and the generator.

In one embodiment, multiple engine-generator device 20 configured to dissipate heat from the electric motor-generator module 10 is more efficient than dissipates heat a single large generator. For example, each of the motor-generator device 20 provides a relatively small motor-generator 20 with a small mass, which easily dissipates heat associated with the generation of electricity. In one embodiment, the electric motor-generator module 10 uses at altitudes above 10,000 feet, where the local temperature is less than approximately 25 degrees Fahrenheit, and relatively cold local okrujaiushaia contributes to the rapid dissipation of heat from a relatively small, the motor-generator 20 with a small mass.

In one embodiment, each engine-generator unit 20 are separated by a gap from the adjacent motor-generator device 20 along the first side of the mounting plate 12. In one embodiment, the alignment of the engine-generator device 20 is chosen to have a density component of the three engine-generator devices 20 per linear foot on the periphery of the mounting plate 12. Are also other valid density of arrangement of the motor-generator device 20. In one embodiment, mounting plate 12 forms the side that is adjacent to the drive gear 14, and the side that is opposite the drive gear 14, and the motor-generator device 20 protrude from the mounting plate 12, which is opposite the drive gear 14, so that the output shafts 24 protrude from the mounting plate 12, which is adjacent to the drive gear 14. Thus, each engine-generator device 20 operates independently and independently connected to the drive gear 14 and is not connected to another of the many motor-generator device 20, so that the engine-generator devices 20 include many redundant generating system is acting in the capacity of the motor-generator. Are also valid for other kinds of connections engine-generator devices 20 with the mounting plate 12, including the installation of the engine generator unit 20 and the drive gear 14 on the same side of the mounting plate 12.

In General, the drive gear 14 is configured with a larger diameter than the diameter of the output shaft 24 of the motor-generator device 20. When the drive gear 14 rotates, the smaller the diameter of the output shaft 24 of the motor-generator device 20 to rotate faster than the drive gear 14. In one embodiment, the increase in the rotation speed (for example, revolutions per minute, RPM) of the output shaft 24 increases the output voltage of the engine-generator device 20. In one embodiment, the drive gear 14 has a diameter of approximately 30 feet, and the output shafts 24 have a diameter of approximately one inch, so that when the drive gear 14 rotates at approximately 70 revolutions per minute (RPM), the output shafts 24 rotate at approximately 25,200 revolutions per minute. High speed rotation of the output shaft 24 results in a high relative speed between the magnets and the coils inside the unit 20, which provides an output voltage that is used to generate energy. For example, in one embodiment, the diameter of the Pref is ne gear 14 is approximately 30 feet, while the diameter of the output shaft 24 of the motor-generator device 20 is approximately 6 inches, so that at each complete revolution of the drive gear 14 around its axis, the output shaft 24 rotates on its axis 60 times (thus, the gear ratio is 30 feet by 6 inches, or 60 to 1). Other gear ratios are also acceptable. In one embodiment, the gear ratio is chosen to optimize performance and output by changing the size of the drive gear 14, the gear 22 of the engine-generator device 20, or both.

In one exemplary embodiment, 282 engine-generator device 20 five horsepower (3728 watt) distributed around the drive gear 14, having a diameter of approximately 30 feet. Each of the 282 engine-generator device 20 includes an output shaft 24 having a diameter of one inch, and the drive gear 14 is rotated by the source of energy (such as wind) at approximately 70 revolutions per minute, so that each shaft 24 of each engine-generator device 20 rotates at approximately 25,000 RPM, producing approximately 1 MW of power, which can be converted into electricity.

Figure 1B is a side view of the motor-generator device 20 according to one variant the GST implementation. The engine-generator device 20 includes a housing 23 of the winding comprising coils of electric wire of the motor and/or generator and associated components of the engine (not shown) of the housing 23 of the winding extends the output shaft 24.

In one embodiment, the shaft 24 includes an axis 25 that is connected to the housing 23 of the winding with the possibility of rotation. It is expected that during use in an engine-generator devices 20 may damage the bearings, which can prevent rotation axis 25. In one embodiment, the axis 25 includes a notch 27 which is configured to selectively cause the fracture of the axis 25 when the bearings inside the housing 23 of the winding obledenelaya or otherwise become sedentary. When one or more motor-generator devices 20 over time wear out, the axle 25 is configured with the ability to break along the notch 27, by making the engine-generator unit 20 is not operational. In one embodiment, the coupling in connection with each engine-generator, while the clutch is configured to derive jammed the motor-generator out of engagement with the drive pinion 14. In one embodiment provided by the solenoid mechanism in connection with each engine-generator, when this solenoid mechanism configured to derive jammed the motor-generator out of engagement with the drive pinion 14. Thus, the motor-generator device 20, which become inoperative, will be automatically eliminated from the electric motor-generator module 10 (Figure 1A) to provide generating capacity backup system with automatic redundancy, in which one or more defective devices 20 do not prevent continuous operation of the electric motor-generator module 10.

In one embodiment, the electric motor-generator module 10 includes excessive amounts of engine-generator devices 20 over quantity, which is designed to provide the required output power. Each of the motor-generator device 20 employed less than 100% output (e.g. output, constituting 96%), so that the total combined amount of the engine-generator devices (including excessive number of devices) contributes in providing 100% of the desired output. As the motor-generator device 20 are worn, broken device 20 automatically fall out of the electric motor-generator module 10, which is described above, and the remaining is in those devices work with several high output (for example, 96,5%), allowing the electric motor-generator module 10 to retain 100% of the desired output.

In one embodiment, provided multiple engine-generator devices 20, including excessive amounts of N, the number N of additional devices 20 remains outside or, in other words, in the configuration of the "off" until then, until you wear out running engine-generator device 20. When the motor-generator device 20 is worn, one of the additional N device 20 is put in the operating state, for example under the action of the controller connected to the electric motor-generator module 10 (Figure 1A). In one embodiment, the electric motor-generator module 10 is connected to the electronic controller to selectively add a healthy engine-generator devices 20 and selective removal of inoperative engine-generator devices 20 to the electric motor-generator module 10 or from it.

In one embodiment, for each one of the separate motor-generator device 20 provides an additional output shaft 24n or more bearings 22n to each individual motor-generator, in addition, consider adding a simple gear what about the mechanism. For example, a separate motor-generator device 20 can include a ratio of 2 to 1, providing the possibility of reducing by half the diameter of the drive gear 14.

Traditionally, the transmit power at high voltage to minimize electrical losses in the transmission lines. Isolate the wires that carry the power of high voltage, inevitably requires significant amounts of electrical insulation. High levels of electrical isolation type a lot, so much isolated generators high voltage are not suitable for aircraft electricity generators.

In one embodiment, the electric motor-generator module 10 includes multiple engine-generator devices 20, each of which is configured to operate at relatively low voltage (for example, between 100-1000 volts) and isolated accordingly, providing the possibility of flight electric motor-generator module 10 in the jet stream. The engine-generator unit 20 low voltage requires less insulation, and weighs less. In addition, several motor-generator device 20 configured to serial electrical connection, for example, so that priblizitelen is 100 engine-generator devices 20, each of which produces approximately 300 volts, were connected in series to provide an electric motor-generator module 10, which provides approximately 30,000 volts. Thus, the combined multiple engine-generator devices 20 low-voltage low mass to provide an electric motor-generator module 10 with a high output voltage.

In one embodiment, the electric motor-generator module 10 includes multiple devices low voltage, grouped in the high voltage system, which is configured to generate electricity at high altitude. Paschen law States that the breakdown voltage of air in the gap is a nonlinear function works gas pressure and the length of the gap. Thus, high altitude (lower air pressure) is associated with a lower breakdown voltage in the electrical system. As a result, when the electrical system will use at high altitudes, to overcome the breakdown voltage in air required additional electrical insulation. The phenomenon of the breakdown voltage described by the Paschen law, is of even greater importance for the wires of small diameter, which are used in the generators e is actionsto with wire winding. For all these reasons, in order to ensure the generation of electricity at high altitude, choose multiple engine-generator devices 20 low voltage light weight (minimum isolated), electrically connected in an electric motor-generator module 10. These characteristics contribute to a very wide range of characteristics of the input/output voltage of the electric motor-generator module 10.

Figure 11 is a structural diagram of the sequence of the motor-generator 400, grouped in parallel to provide the desired output voltage for the electric motor-generator module 10 according to one variant of implementation. In one exemplary embodiment, the number of engine-generators (engine-generators and up to the engine-generators n) are connected together in series with the provision of the output voltage for each electrical what about the engine-generator module 10 (Figure 1), and the number of such modules are connected in series so that each generating electricity system 100 (Figure 8) modules produces approximately 1 MW of power. In one embodiment, the adaptability of the desired output voltage of the system is provided by selective connection of the electric wires a few engine-generators (a...n) or steam engine-generators of a given output voltage in various combinations. Thus, the output voltage of the system to selectively change through selected combinations of the connection electric wires without changing the output voltage of each engine-generator. In one exemplary embodiment, a large number of the motor-generator low voltage (for example, less than about 500 volts) are grouped in parallel or in series connected with the provision of approximately 5,000 volts from a single electric motor-generator module 10, or fewer of the motor-generator high voltage (for example, more than about 500 volts) connected in series with the provision of approximately 5,000 volts from each electric motor-generator module 10, as described in detail in the examples below.

Example 1

In one exemplary embodiment, about what westline, 1 MW electric motor-generator module 10 (Figure 1) is equipped with ten motor-generator 20, each of which produces approximately 0.1 MW. In one exemplary embodiment, is required to provide approximately 20,000 volts down to the Ground node 40 halyard, the system 100, as illustrated (Figure 8), includes four electric motor-generator module 10, so that each electric motor-generator module 10 configured to generate approximately 5,000 volts. Approximately 20,000 volts down to the Ground node 40 file provide by providing ten engines of approximately 500 volts each, with the motors connected in series.

Example 2

In one exemplary embodiment, the motor-generator 20 is chosen to generate approximately 1,000 volts instead of 500 volts. Data pairs 1000 volt motor-generators connected in parallel, and together consistently connect five such pairs to generate electric motor-generator module 10 required approximately 5,000 volts. In this approach, the current decreases, because for electric motor-generator module 10 of the same approximately 10 MW of power used 1000 volt engine-generator. Reduced the e current provides the ability to use less wire and fewer turns, that leads to the machine lighter weight. Thus, each electric motor-generator unit 10 reduces the amperage in half despite the fact that it still produces the same approximately 1 MW of total power. Reduce the power by half provides the possibility of using fewer turns of smaller wire that leads to the module with a lighter weight.

Example 3

In one exemplary embodiment, to provide approximately 30,000 volts down to the Ground node 40 halyard apply three hundred "small" engine-generators of the four electric motor-generator modules 10. 30,000 volts down to Earth from the four electric motor-generator modules 10 is transmitted to each electric motor-generator module 10 having a power output of approximately 7,500 volts. 7,500 volts from each module with a uniform distribution on trentham engine-generators leads to the production of each engine-generator approximately 25 volts. Through a serial data connection, three hundred 25 volt engine-generator will generate approximately 7,500 volts from each module and approximately 30,000 volts down to Earth on the halyard. In one embodiment, some of the engine-generators are redundant the suspended motor-generators, so even if a few of the motor-generator during the flight fails, will remain a sufficient number of the motor-generator to generate the desired and the calculated output voltage of the system.

SUBSTANCE: transmission comprises main differential gear 120 with invariable gear ratio adjusted by reactive torque provided by rpm control gear 150 inside man gearbox. Note here that it comprises also extra differential gear 220 in rotary engagement to input 50 via first flow 115 and with rotary engagement with gear 150 controlling rpm via second flow 125. Note here that extra differential gear comprises two parallel power flows P' and P". First flow comprises hydraulic bypass line with two hydraulic devices 180, 500 making hydraulic circuit. Transferred power and direction of it transfer in circuit P' with bypass line vary in operation are selectively varied in operation to vary speed in path P'', thus, varying power in second part and reactive torque of rpm control gear, thus, adjusting gear ratio. Transmission exploits first and second paths for entire range of input rpm.

EFFECT: simplified design, decreased dimensions, weight and costs.

SUBSTANCE: driving mechanism for a power-generating device 5 provides for a link between a power generator 20 and a turbine 10, which rotates with varying frequency. The rotating driving mechanism provides for a generator 20 rotation at the outlet with a fixed rotation frequency. The driving mechanism includes a differential gear box (16), which has two output shafts. One drives the generator 20 by means of the shaft 26, and the other one drives an electric machine 30 by means of the transfer 18. The varying reactive torque provided by the electric machine 30, may be used for control of torque and rotation frequency at the outlet shaft 26. The input torque from the turbine 10 is measured in the point of application of gear box 16 reaction, and this measurement is used to change reactive moment provided by the electric machine 30.

EFFECT: inertia in a gear box and inertia of an electric machine are reduced to zero for provision of almost instantaneous change of reactive torque and by means of this for more efficient control of output shaft rotation frequency.
