Description

Device for electromagnet to rotate shaft

The invention relates to an electromagnet used for shaft rotation. More specifically, a plurality of permanent magnets are provided so as to be rotatable about the shaft together with the shaft, one electromagnet is provided outside the periphery of the plurality of permanent magnets, and a device for operating one electromagnet is provided. Two secondary batteries are used to operate the electromagnet, which rotates the plurality of permanent magnets. Using the back electromotive force generated on the electromagnet, the plurality of secondary batteries are charged. In addition, a plurality of coils are provided around the plurality of permanent magnets, and the plurality of rotating permanent magnets causes the plurality of coils to generate electricity.

In the use relay circuit, a transistor used as a switch is connected to a terminal of the relay, and the transistor is connected to the cathode side of the battery. When the relay is connected to the battery and blocked, a higher voltage than the battery voltage will instantaneously occur on the relay. The resulting high voltage can damage the transistor used as a switch. To solve this problem, a diode is used, the anode of the diode is connected to the terminal of the relay connected to the cathode side of the battery, and the cathode of the diode is connected to the terminal of the relay connected to the anode side of the battery. Therefore, the electricity generated in the relay flows from the anode of the diode into the cathode. In other words, after a high voltage instantaneously occurs on the terminal of the relay that is blocked on the cathode side of the battery, electrons in the relay terminal connected to the anode side of the battery flow from the cathode side of the diode into the anode side and into the relay. The high voltage that occurs on the relay is the back electromotive force that occurs when the battery is connected to the relay and is blocked.

When a battery is connected to the electromagnet, multiple electrons flow from the cathode of the battery into the anode of the battery. When the cathode of the battery is blocked by the electromagnet, a plurality of electrons no longer flow into the electromagnet from the cathode of the battery, and a plurality of electrons will flow into the anode of the battery. The electrons in the electromagnet are driven by the magnetic force of the electromagnet Continue moving forward. Then, the electrons in the electromagnet disappear from the terminal side where the cathode of the battery is blocked. Therefore, a difference in the number of electrons occurs between the side connected to the anode of the battery and the blocked side at the cathode side of the battery, and the difference changes. The difference between the number of electrons on both sides first becomes larger and then becomes smaller. The difference in the number of electrons generated in the electromagnet is the back electromotive force. The back electromotive force gradually becomes larger, and when the difference in the number of electrons on both sides is the largest (that is, electrons are only half of the electromagnet), the peak is reached. Then gradually become smaller until it disappears.

When the electromagnet is blocked in the secondary battery (secondary battery-1), the back electromotive force generated by the voltage of the electromagnet through the electromagnet is higher than the voltage of the secondary battery-1 instantaneously. If the anode and cathode of the secondary battery-1 are all blocked at the two terminals of the electromagnet, the electromagnet instantly becomes a power source, and the electromagnet blocked at the cathode side of the secondary battery-1 The terminal (terminal B) becomes the anode, and the terminal (terminal A) of the electromagnet blocked on the anode side of the secondary battery-1 becomes the cathode. If multiple electrons can flow into the B terminal of the electromagnet from the anode of another secondary battery (secondary battery-2), but cannot flow backwards, and multiple electrons can flow into the secondary battery from the A terminal of the electromagnet- The cathode of 2, but cannot flow backward, a plurality of electrons flow into the cathode from the anode of the secondary battery-2, and the secondary battery-2 is charged.

Then later when the anode of the secondary battery-1 is connected to the A terminal of the electromagnet, a plurality of electrons flow into the anode of the secondary battery-1 from the electromagnet. A plurality of electrons flow into the B terminal of the electromagnet from the anode of the secondary battery-2 through the back electromotive force generated on the electromagnet.

Further, by the back electromotive force generated on the electromagnet, the electromagnet operates, the power consumption of the secondary battery-1 is reduced, and the secondary battery-2 is charged.

WIPO WO 2015/142084 A1 (2015.09.24) (KR 10-1733373 B1 (2017.05.08)) is its prior art (prior art). In this invention, the cathode of the secondary battery is blocked at the terminal of the electromagnet. When the cathode of the secondary battery is blocked, a plurality of electrons flowing into the electromagnet continue to flow into the anode of the secondary battery. A plurality of electrons in a capacitor flows into the electromagnet through the counter electromotive force generated on the electromagnet, and a plurality of electrons should flow into the capacitor and the electromagnet at the anode of the secondary battery. The electrons flowing into the electromagnet continue to flow into the anode of the secondary battery.

An object of the present invention is to use one electromagnet to rotate a shaft together with a plurality of permanent magnets, and use the back electromotive force generated on the electromagnet to reduce power consumption of a plurality of secondary batteries.
