Abstract

PURPOSE: An electric generator is provided to increase the efficiency of power generation by changing magnetic flux within a power-generating coil to generate electromotive force. CONSTITUTION: A rotating coil(7), a holder(8), and a power-generating permanent magnet(10) are coupled to a rotational axis(14). Upper and lower portions of a rotating core(15) have a different shape each other. Weight of one of the upper and lower portions is greater than that of the other centering around the rotational axis(14). In a stationary state, a weighty portion of the rotating core(15) is always directed to a lower direction so that a switching semiconductor(4) is always operated by facing an optical sensor(3) and a mirror(9). For eliminating interaction force, a magnetic field screening shield(13) is interposed between a rotating permanent magnet(12) and the power-generating permanent magnet(10).

Description

A device using a portion of electricity generated by the storage battery (1) as a power source for the rotating coil (7)

In order to generate electricity, aberrations or incineration fuels are used, so the power generation equipment is large, power loss and cost are high, and fossil fuels pollute the air.

In addition, since the contact between the brush 5 and the commutator 6 is made in the vertical direction with the rotating coil, and the contact is not made during rotation, the supply of current is unstable and an electric spark is generated. And while the rotary coil 7 rotates, noise is generated due to friction with air.

The present invention is a device that generates power by using a moving energy source other than aberration or fossil fuel, and the structure that is driven without breaking the contact between the brush (5) and the refiner (6) and the rotating coil (7) is rotated To minimize friction with air.

The structure of the present invention is the rotary coil 7 and the holder 8 and the permanent magnet 10 for power generation are coupled together to the rotating shaft 14, the top and bottom shape of the rotating core 15 is different and the weight of one side Is turned around the axis of rotation 14 so that the heavy side is always downwards, so that the position of the optical sensor 3 and the position of the optical sensor mirror 9 face each other in the stationary state. The semiconductor 4 is always operated.

The magnetic shielding shield 13 is made of a material having a high specific transmittance of magnetic force between the rotating permanent magnet 12 and the power generating permanent magnet 10 so that the rotating permanent magnet 12 and the power generating permanent magnet 10 are installed. ) To eliminate interaction between them.

In addition, the position of the commutator 6 is arranged in the same direction as the rotary coil 7 (FIG. 3) to form the shape of the commutator 6 in a circular shape so that the state of contact with the brush 5 is always maintained.

In the operation of the present invention, when the power user moves the slide switch 2 from the terminal 2-1 position to the battery terminal 2-2 position, power is supplied from the battery 1 to the optical sensor 3. As the light sensor 3 is operated to emit light, the light is reflected by the mirror 9 for the light sensor and enters the light sensor 3 to generate a current to drive the switching semiconductor 4 so that the current is ( The current flows through the rotary coil 7 via the +) stage brush 5-1 and the (+) stage commutator 6-1.

When current flows through the rotating coil 7, the rotating coil 12 receives a magnetic force and rotates due to the magnetic field generated by the rotating permanent magnet 12 fixed to the case 20.

At the same time, by rotating the rotary shaft 14 and the permanent magnet 10 for power generation by changing the speed of the magnetic force lines generated inside the power generation coil 10, the electromotive force is generated in the power generation coil 11 to generate power.

After 30 degrees (30 degrees in Fig. 2) is rotated so that the light sensor 3 is out of the position of the light sensor mirror 9, the light sent from the light sensor (3) does not come back to the light sensor (3) Since the switching semiconductor 4 does not generate a current to be sent to the switching semiconductor 4, the driving stops and the current does not flow to the rotating coil 7 so that the rotating coil 7 does not receive a magnetic force. After the rotation of 180 degrees (180 degrees rotation of Figure 2) is to rotate by the inertial force.

When the light is turned 180 °, the light sent from the optical sensor 3 is reflected by the optical sensor mirror 9 and returned to the optical sensor 3 so that a current is generated in the optical sensor 3 to drive the switching semiconductor 4. As the current flows through the rotating coil 7, it rotates with the same magnetic force as that of the 0 degree state in FIG. At this time, when the rotary coil 7 rotates, the permanent magnet 10 for power generation combined with the rotary coil 7 also rotates, and thus the speed of the magnetic field lines of the magnetic field formed inside the power coil 11. Since the change of electromotive force is generated to generate electricity. After about 5 seconds in such a power generation state, the rotary coil 7 and the permanent magnet 10 for power generation have a stable rotational force, and power generation is also found to be stable. Then, the power user switches the slide switch 2 to the position of the power generation terminal 2-3. When switching to the power generation terminal (2-3) position, the current coming from the battery (1) is cut off, while the current flowing through the AC-DC converter (16) in the output terminal 21 is a self-generated. At this time, the intensity of the voltage or current is properly adjusted to the magnetic flux density of the permanent magnet 10 for power generation and the length of the power coil 11, that is, the number of windings, the power user will obtain the required power.

In addition, in order to reduce noise due to air friction generated when the holder 8 and the rotating coil 7 are rotated, a fan-shaped fan 17 is installed in the holder 8 to vent holes of the case 20. By releasing air through (18), the air density is reduced, which reduces air friction.

It is possible to freely generate and use the electric power required by the electric power user, and it is particularly suitable for island areas, homes, and automobiles.
