Description

Current generation unit and operating device for generator using the same

The present invention relates to a generator, and more particularly, to a driving device of a generator for generating an electromotive force using a rotational force by an external force.

In general, a generator is a device that converts external force, which is mechanical energy, into electrical energy, and is used in various fields. In particular, generators are being developed in various countries around the world to produce electric power using wind or tidal power, which is clean energy, due to the seriousness of energy crisis and environmental pollution caused by exhaustion of fossil fuel.

Looking at the power generation process of the generator based on the wind, the drive shaft is connected to the fan to generate a rotational force by receiving the wind, and the gearbox is provided to increase the rotational speed of the drive shaft connected to the generator. The generator causes the rotor (rotator) connected to the increase gear to rotate, thereby generating electromotive force by electromagnetic induction between the rotor and the stator (fixing body).

That is, the conventional generator must be provided with an increase gear in order to use a low-speed rotational force, such as wind power, and since the generator must also have a separate space, it takes up a large volume for large-capacity power generation. In addition, there is a problem that a loss of power occurs while passing through the gear. Therefore, in the case of a generator that generates electric power using such wind power, the external force may not always work sufficiently, and it should be able to be developed with high efficiency even at a low speed.

In addition, the conventional generator obtains an electromotive force through the relative rotation between the rotor and the stator. In many general conventional technologies, including the Korean patent application 2008-0083105, a plurality of stators are radially installed and crosses each stator as the rotor is rotated. You get an electromotive force.

However, the counter electromotive force is generated in the process of rotating the rotor while crossing the stator. Thus, the counter electromotive force interferes with the relative rotation between the rotor and the stator, resulting in a problem of lowering energy efficiency.

In addition, conventionally, due to excessive back EMF generated during load in the relative rotation process between the rotor and the stator, there is a problem that the efficiency of the generator falls.

Alternatively, an operation plate (not shown) for transmitting external force may be connected to the guide shaft 290 connected to the moving body 280 of the current generating unit 200. The operation plate is rotatably installed on the rotation shaft of the device housing, the operation plate is formed with a guide rail for walking on one side of the guide shaft 290 connected to the movable body 280, when the operation plate is rotated The movable body 280 has a structure in which the linear reciprocating motion is performed.

As such, when the operation plate is rotated by an external force, as the guide shaft 290 linearly moves along the guide rail, the movable body 280 repeatedly enters the inside of the through hole of the fixture 250. Electromotive force is generated by electromagnetic induction.

FIG. 7A illustrates a state in which the movable body 280 moves to the left to generate an electromotive force through electromagnetic induction by forming a magnetic field in the direction of the fixed body 250 on the left side, wherein the outer skin part 220 is the movable body ( 280 to further maximize the magnetic field.

In this state, when the guide shaft 290 is pulled to the right by an external force, the movable body 280 is linearly moved in the direction of the other fixed body 250 on the right side, at which time high The counter electromotive force is generated by the stagnation 250. However, the mobile unit 280 is subjected to the attraction force to be located in the center by the ring portion 225, so the counter electromotive force can be overcome relatively easily.

Through this process, the movable body 280 is located on the right side is illustrated in FIG. 7B. And the AC power is generated in the above process is repeated at high speed.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.
