Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generating apparatus using a DC motor,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generation device, and more particularly, to a power generation device using a DC motor that can generate a large amount of electricity using minimum energy transmitted from a DC motor.

Generally, an energy source is required for power generation, and various types of energy are used for power generation. For example, wind power and solar power generation systems are clean energy, and they are continuously developing technologies in various countries around the world after the energy crisis. Commercialization has been actively under way.

However, in the case of a power generation system that uses sunlight, which is employed in a conventional power generation system, as an energy source, the power generation can not be efficiently performed because the power generation system is affected by the weather change.

On the other hand, wind power motors, which produce electricity using wind power, can supply electric power even under conditions like sunless weather, and can generate electric power more efficiently than solar power generation systems in mountainous terrain like Korea.

As such, wind power generators that generate electricity using the wind power have been studied as alternative energy sources as resources of petroleum, coal, and natural gas have been exhausted due to the development of industry and population increase.

On the other hand, the wind power generator is composed of a windmill rotating by the wind to convert wind power into mechanical energy, a support structure supporting the windmill at a certain height from the ground, and a power generating device generating electricity using mechanical energy generated by the windmill. Here, the windmill has been developed in various shapes and structures for more effective development, and a windmill in which a plurality of blades are radially formed around a rotor is widely used.

However, the above-described general wind turbine generator can effectively generate electricity in a proper wind speed, but the wind speed in the natural state is not constant. When the wind speed is low or the wind speed is low, the wind turbine does not rotate or generate electricity The wind turbine is not rotated at a sufficient speed to perform its functions, and when the wind speed is very high, there are many problems such as damaging the wind turbine and the support structure and the power generation device.

On the other hand, Korean Patent Application Publication No. 10-2011-0035802 (a name of a power generation device using a rechargeable battery) is a device that rotates a direct current (DC) motor through the electric energy of a DC battery, It is possible to increase the number of revolutions of the motor generator by twice as much as the number of revolutions of the motor to increase the number of electric energy .

However, just by changing the size of the gears, there is a limit to producing more electricity with the electric energy of the DC battery.

A second DC motor 28, which is a separate power source, is further installed in the driving unit 10. The second DC motor 28 stops the driving of the first DC motor 12 after the first weight wheel 42 which is the speed increasing portion 40 starts to rotate by the power of the first DC motor 12, The first weight wheel 42 which is the speed increasing portion 40 can be rotated by the power of the second DC motor 28 whose output is lower than that of the first DC motor 12.
