In order exemplary document PI9102642-3 autoexcitado describes a synchronous generator motor injected copper or aluminum. Such generators are used coupled to an internal combustion engine having means which allow the generator to operate at the most appropriate speed range of the engine.Currently, the known generators to generate electricity at a desired frequency generally behave the rotation set, ie 1800 rpm 60 Hz, 1500 rpm 50 Hz These conventional generators and alternators have a high energy consumption at the time of starting and consumption energy elava considerably.The generators are devices for the production of electricity, alternative sources of energy, and exist in various forms and types. The different types of generators include, for example, electric generators, portable wind generators, emergency generators and RV generators. Each type has a specific function and can be fed, for example, propane gas, gasoline, natural gas and diesel. All these forms of energy are used as initial force to fuel generators, contributing to global warming and harm the environment.A fully electric generator does not pollute. However, when using an electric motor, engine power is greater than the power of the generator. Thus, the energy generator to generate power through electrical alternator electric motor is greater than the power to be generated, to produce because the pulling force would require the motor to consume more power that the generator generates.Summary of the InventionThe present invention relates to a system for generating electricity comprising a frequency inverter three phase, three-phase electric motor, alternator and a generator includes a shaft that conforms or at least a solid concentrically disposed between the electric motor and generator. Such elements, properly arranged, allow the set to operate in rotation and traction force appropriate to the operation of the electric motor, which drives the generator to saving energy consumption for generation without considerable loss of power output and current output.Obietivos the InventionIn view of the problems described, and in order to overcome them, we propose a system to generate electricity that is powered by electricity.The cost of power generation is less than the cost of generating combustion, can generate benefits for medium and large consumers, reducing operating cost through energy savings.Moreover, when it generates a large amount of electricity from low electricity consumption, contributes to the environment and reduces the cost of generation.The cost of generation is reduced due to the replacement of the combustion engine by an electric motor. Thus, the energy consumption to be provided by the initial source that feeds the engine is electricity.The objectives of the present invention are achieved by a system for generating electricity using an axle or conforms includes at least a solid mass concentric with appropriate that, in turn, due to the transfer of inertia of its mass in displacement rotation kinetic energy generated by a centrifugal force, increasing the engine speed. Thus, the motor is replaced by the pull force required to move the generator shaft connected to a load.The system of generating electrical energy comprises a frequency converter connected to an electric motor for controlling rotation of the motor, alternator and generator connected to the electric motor via a shaft which includes at least one or conforms solid structure concentrically disposed between the altemador electric motor and generator, the mass of the shaft that includes or conforms at least a solid concentric proportional to power the electric motor.The proper rotation is defined as a generator voltage and frequency. To obtain the proper rotation is required inverter frequency as the engine speed low or high speed for the proper rotation of the generator.Thus, the engine power can be up to four times smaller than the electric power generator. Thus, although the engine being inferior to the generator, the consumption of electricity consumed by the engine to generate drops considerably, ie, is consumed little power and generates a lot of electricity.Furthermore, the voltage and number of phases of the motor and generator may be identical or different.The power generation system of the present invention allows the use of an electric motor coupled by a shaft conforms or that includes at least one solid structure concentric to an electric generator alternator. The electrical generator starts to generate electricity with low power consumption, since consumption of the motor becomes smaller, consuming a smaller amount of initial energy source to rotate the generator shaft.The advantage of the electric motor generator alternator of the present invention in relation to other existing generators alternators is the generation of electricity with low power consumption to perform work rotation of three-phase generator.The system of power generation is easy to use, as it features a compact structure. The mounting base is light, since the motor is lightweight and does not use any type of tank liquid or gaseous fuel.The system for generation of electricity is silent because the engine and generator are electric, and also because the axis that includes conforms or at least a solid concentric produces no noise, since it does not suffer intense friction.The present invention will be described below with the aid of drawings, but which are not absolutely limiting where it can be observed other details and advantages of the present invention.Brief Description of the DrawingsFigure 1 - A schematic representation of the system of power generation of the present invention.Detailed Description of the DrawingsFigure 1 shows a system for generating electricity comprising a three-phase inverter frequency 1 connected to a three phase electric motor high speed (2) and a three-phase alternator generator 8.The system further comprises a shaft conforms or 4.1 that includes at least a solid frame 7 concentrically disposed between the motor 2 and the generator 8 to generate a tensile force required to decrease energy consumption while maintaining, in whole or in part, the tensile strength of the electrical alternators generators provided by the electric motor.The solid structure concentric 7 may have a variety of shapes, such as square, rectangular, hexagonal, round, spherical, oval, and star and others.In a preferred embodiment, the shaft conforms or comprising at least a solid concentric 7 as well as the very solid structure concentric 7 are constructed of resilient metal, the latter of which has a rounded shape of a wheel.As can be seen in Figure 1, the system further comprises a metal shaft connecting the motor 2 4.1 generator 8 couplings 3.1 and 3.2 which are used to secure the second motor shaft 7 to the wheel axis and the wheel axis 7 generator shaft 8:01 support base and fastening the equipment (9).The masses 4.1 shaft and concentric solid structure 7 are proportional to the power of the engine 2, and the mass of the solid structure concentric 7 must be seven to nine times the mass of the shaft 4.1, more preferably eight times, most preferably nine times. Thus, each horsepower - CV of the electric motor 2, the sum of the masses of 4.1 shaft and concentric solid structure 7 must be between 5 Kg and 15 Kg per unit of horsepower electric motor (2) more preferably between 8 kg to 12 kg, even more preferably 10 kgThus for a 5 HP motor 2, the sum of the masses of solid structure concentric shaft 7 and the metal should be 4.1 to about 50 pounds. Whereas the mass of the metal shaft 4.1 is about 1 kg per VC, the mass of the solid structure 7 is concentric about 9 kg per CV.The generator phase altemador 8 provides energy savings to be consumed in work for the generation of electricity, and can be configured with the power of 10 KVA to 300 KVA in single phase, two phase or three phase, and may be above or below these powers.In a preferred embodiment, the system uses an electric motor 2 high-spin to work in low speed. The inverter controls the rotation of the motor 2 rotation and to achieve the ideal frequency of the system which are determined by obeying the speed and frequency of the generator 8, which can be 50 Hz or 60 Hz, depending on the desired tension. Only when the system reaches the optimum tension is that energy is released for consumption by an electrical control connected to the output of the generator 8, or the control only releases energy when the generator 8 reach the rotation, frequency and voltage suitable for power loads, avoiding under-and overvoltage.In fixing the axle bearing is used 4.1 6.1 and 6.2 5.1 and bearing 5.2. The shaft weighs about 4.1 kg per 1 HP / HP in relation to the engine power, so there is a transfer of adequate inertia.In a preferred embodiment, the metal wheel 7 weighs about 9 kg per hp / HP in relation to power the electric motor so that there is adequate transfer of inertia.In the preferred embodiment, the electric motor can be of direct current or alternating current and is controlled by a frequency inverter 1, which reduces power consumption when starting the engine and controls the rotation of generation (which may be substituted by any other similar equipment with the power of 10 KVA to 300 KVA, single phase, two phase or three phase).In a second preferred embodiment, the generator (8) has a power of 10 KVA to 300 KVA.Having described examples of preferred embodiments, it should be understood that the scope of the present invention encompasses other possible variations, being limited solely by the terms of the appended claims, including therein the possible equivalents.
