JP2006-340589 (P2006-340589A) Japanese Patent Application Publication No. 2011-259561

Conventional generators have had the following problems:
(b) Conventional power generators depend on external energy sources such as thermal power generation, which requires fossil fuels, and hydropower, wind power, and solar power generation, which require natural energy, and as a result, their locations are limited.
(b) As a countermeasure, flywheels have begun to generate and store electricity, but conventional power generation equipment suffers from large energy losses in the motor, generator, and other parts of the power generation equipment, resulting in insufficient energy circulation and unstable operation. It required external energy.
(c) Conventional flywheel power generators use external energy to rotate the flywheel using a motor, which converts the kinetic energy into electrical energy in a generator to generate electricity. Energy flows in one direction, such as charging the battery or supplying it externally, and there was no mechanism in place to circulate or amplify the energy.
(d) Although the flywheel has kinetic energy and inertial energy as a rotating body, it has not been possible to efficiently store these energies and utilize them as power generation energy. In particular, it was not possible to circulate, amplify, and utilize the energy sufficiently.
(e) Providing energy circulation and amplification of power generation between the flywheel, generator, and motor, reducing flywheel rotational resistance to store kinetic energy of the flywheel, and moving the flywheel with high efficiency using surplus energy. Conventional power generation devices have the problem of requiring external energy, as they are insufficient in many aspects, such as conversion to energy.
The present invention has been made to solve these problems.

In this power generation system, power is supplied to the motor from an external power source or storage power source only during startup, and after the flywheel has rotated stably and the generator has generated sufficient power, the power to the motor is circulated from the generator. Switch. (The flywheel can be rotated manually at startup.) Although the flywheel requires a lot of energy at startup, it does not require that much energy after stable rotation, so the above measures provide sufficient power for the load at startup. By supplying power for flywheel rotation using a portion of the electric energy generated by the generator after stable rotation, it is possible to circulate and amplify kinetic energy and generated energy.

In this power generation device, the kinetic energy transmission parts of the motor shaft, flywheel shaft, and generator shaft are physically connected with pulleys and belts to reduce kinetic energy loss, and the motor shaft and motor receiver are made non-contact. By making the generator shaft and generator receiver non-contact, conversion loss between kinetic energy and electrical energy is reduced, allowing highly efficient power generation. (Kinetic energy transmission parts are not limited to pulleys and belts as long as transmission is possible.)

The power generating device is a generator that generates alternating current power, and by outputting the alternating current power generated by the power generating device to the alternating current power grid as it is, it is possible to utilize the power generated by the alternating current device. The battery charger may further include a battery charger that converts the DC power into DC power and supplies the DC power to the battery.

As mentioned above, it is basically a generator that generates AC power, but by configuring the power generation device with a DC motor and DC generator, it can generate DC power and output it to the DC power grid, allowing DC equipment to You can also use the generated power. This configuration can efficiently handle cases such as charging by directly connecting to a battery.

The power generation device may further include a converter that receives power from the battery, converts the DC power of the battery into AC power, and supplies the AC power to the motor.

The power generation device may include a transformer that supplies power to the outside between the power generator and the battery charger. By providing this transformer, the AC power generated from the generator can be used directly outside. In this case, there is no need to convert the DC power from the battery into AC power, so the efficiency is better than when power is supplied from the battery.

The pulleys and belts that connect the flywheel, motor, and generator are basically divided into two belt systems with two pulleys connected by one belt, but they can also be configured by placing three pulleys on one belt system. . This reduces frictional resistance.
This is an energy circulation/amplification type flywheel power generation device having the above features.

No external energy supply is required except during startup, and the energy is circulated and amplified within the generator to enable continuous and stable power generation, making it effective as a semi-permanent rotating/generating engine.

Therefore, it is not affected by day or night, weather, water resources, fuel resources, etc., and does not generate carbon dioxide, so it is effective in realizing clean power generation and power supply without fuel.

In addition, there is a high degree of freedom in the installation location. This technology makes it possible to install and generate power anywhere, including in the wilderness, in the countryside, in the city center, on top of moving vehicles, in outer space, on the moon, and on other planets.

Electrically, the power source of the motor 10 is connected to a generator 30 and supplied with generated power.

The belt connects the three by transmitting the rotational motion of the motor 10 to the flywheel 20 and the rotational motion of the flywheel 20 to the generator 30.
(Yo)
As long as the motor 10, flywheel 20, and generator 30 can be connected to each other while sufficiently transmitting rotational motion, the belt and pulley shown in the figure may be replaced with other equipment or materials such as a chain or a shaft drive.

The external connection from the tap 70 is not limited to the battery charger 80 and the battery 81, but may be any external connection such as a device connection, a building power supply connection, or a power selling equipment connection. Alternatively, it may be directly connected to the generator 30 without using a tap.

Switch to circulating supply. (The flywheel can be rotated manually at startup.) Although the flywheel requires a lot of energy at startup, it does not require that much energy after stable rotation, so the above measures provide sufficient power for the load at startup. After stable rotation, part of the electric energy generated by the generator is circulated to the kinetic energy of flywheel rotation by motor rotation, amplified to generated energy by the generator, and then continuously and continuously. It is possible to generate electricity by repeating a series of energy circulation and amplification.
