Description

APPARATUS FOR OPERATING AS DC (DIRECT CURRENT) GENERATOR AND DC MOTOR
The present invention relates to an apparatus for operating as DC (Direct Current) generator and DC motor. More specifically, two permanent magnets are placed to be able to rotate with a shaft and one coil is placed outside the circumference of the permanent magnets and two secondary cell batteries are connected to the coil. If the shaft rotates without using the secondary cell batteries, the secondary cell batteries are charged by the rotating permanent magnets. One device for making electric current flow in the coil is placed and the secondary cell batteries are used to supply electric current to the coil. The secondary cell batteries are charged by using back-emf which occurs to the coil.
In an electronic circuit using a relay, a transistor which is used as a switch is connected to a terminal of the relay and the transistor is connected to the negative side of a battery. As the battery is connected to the relay and disconnected, a voltage higher than the battery voltage occurs momentarily to the relay. This occurred voltage damages the transistor. In order to solve this problem, a diode is used in which the anode of the diode is connected to the relay of which one terminal is connected to the negative side of the battery and the cathode of the diode is connected to the relay of which other terminal is connected to the positive side of the battery. By doing this, the electricity that occurs to the relay flows from the anode of the diode to the cathode of it. In other words, a high voltage occurs momentarily to the relay of which the terminal is disconnected from the negative side of the battery and so electrons at the relay of which the terminal is connected to the positive side of the battery flow from the cathode of the diode to the anode of it and flow to the relay. The occurred high voltage to the relay is back-emf that occurs to the relay as the battery is connected to the relay and disconnected.
As a battery is connected to a coil, electrons flow from the negative terminal of the battery to the positive terminal of the battery. As the coil is disconnected from the negative terminal of the battery, electrons do not flow anymore from the negative terminal of the battery to the coil and electrons continue to flow to the positive terminal of the battery and electrons in the coil continue to move forward by the magnetic force of the coil. Within the coil, electrons start to disappear from the terminal which is disconnected from the negative terminal of the battery. Therefore, the number of electrons in the side which is connected to the positive terminal of the battery and the number of electrons in the side which is disconnected from the negative terminal of the battery are different and the difference changes. The difference in the number of electrons of two sides becomes bigger and then becomes smaller. The difference in the number of electrons which occurs in the coil is back-emf. The back-emf becomes bigger and reaches its peak as the difference in the number of electrons of two sides is largest (that is, as electrons exist only in one half of the coil). And then it becomes smaller and disappears.
The voltage of one coil becomes higher than the voltage of one secondary cell battery (secondary cell battery-1) instantly by back-emf which occurs to the coil as the secondary cell battery-1 is disconnected from the coil. If both the positive terminal and the negative terminal of the secondary cell battery-1 are disconnected from both terminals of the coil, the coil becomes a power source instantly and the terminal (terminal B) which is disconnected from the negative terminal of the secondary cell battery-1 becomes the positive terminal and the terminal (terminal A) which is disconnected from the positive terminal of the secondary cell battery-1 becomes the negative terminal. If electrons can flow from the positive terminal of other secondary cell battery (secondary cell battery-2) to the terminal B of the coil but cannot flow reversely and electrons can flow from the terminal A of the coil to the negative terminal of the secondary cell battery-2 but cannot flow reversely, then electrons flow from the positive terminal of the secondary cell battery-2 to the negative terminal of the secondary cell battery-2 and the secondary cell battery-2 is charged.
By doing this, the coil activates and the power consumption of the secondary cell battery-1 is reduced and the secondary cell battery-2 is charged by the back-emf which occurs to the coil.
US 6 777 838 B2 (17. 08. 2004) discloses a method of increasing the power output of existing permanent magnet motors. Increased power output is achieved by more completely utilizing the magnetic field of motor permanent magnets during running. The apparatus is external to the motor and therefore eliminates the need for modications to the motor itself. Photointerrupters, Hall effect sensors, FETs, and two sets of batteries are used to utilize back-emf. As back-emf occurs to an electromagnet, electrons flow from the positive terminal of one set of batteries to one terminal of the electromagnet and flow from another terminal of the electromagnet to the positive terminal of another set of batteries.
In WIPO WO 2015/142084 A1 (24. 09. 2015) (KR 10-1733373 B1 (08. 05. 2017)), the negative terminal of a secondary cell battery is disconnected from an electromagnet. Electrons which flowed to the electromagnet continue to flow to the positive terminal of the secondary cell battery as the electromagnet is disconnected from the negative terminal of the secondary cell battery. By back-emf which occurs to the electromagnet, electrons in a capacitor flow to the electromagnet and also electrons flow from the positive terminal of the secondary cell battery to the capacitor and the electromagnet. The electrons which flowed to the electromagnet continue to flow to the positive terminal of the secondary cell battery.
The purpose of the present invention is to rotate a shaft by using two permanent magnets and one coil and two secondary cell batteries and to reduce the power consumption of the secondary cell batteries by using back-emf which occurs to the coil. Also, it is to charge the secondary cell batteries by the rotating permanent magnets if the shaft rotates without using the secondary cell batteries.
In order to achieve the above purpose, the present invention comprises:
permanent magnets which are placed to be able to rotate with a shaft wherein N pole of one of the permanent magnets faces the shaft and S pole of another of the permanent magnets faces the shaft;
a coil which is placed outside the circumference of the permanent magnets;

a rotating component which is placed on the shaft and is configured to repeatedly pass and block light of photointerrupters;
a device for making electric current flow in the coil, wherein the positive terminal of the first secondary cell battery and the terminal A of the coil are connected by a first P channel FET, the terminal B of the coil and the negative terminal of the first secondary cell battery are connected by a first N channel FET, the positive terminal of the second secondary cell battery and the terminal B of the coil are connected by a second P channel FET, the terminal A of the coil and the negative terminal of the second secondary cell battery are connected by a second N channel FET,
wherein a FET is configured to turn on as the light of a photointerrupter is passed by the rotating component and the FET is configured to turn off as the light of the photointerrupter is blocked by the rotating component,
wherein the first P channel FET and the first N channel FET are configured to be set to turn-on to make electric current flow in the coil at a position where a first one of the permanent magnets starts to face a side L of the coil,
wherein the second P channel FET and the second N channel FET are configured to be set to turn-on to make electric current flow in the coil at a position where a second one of the permanent magnets starts to face the L side of the coil,
wherein the following routines A and B are alternately performed as the rotating component rotates,
routine A: ① both the first P channel FET and the first N channel FET are turned on and so the coil is activated by the first secondary cell battery, and ② both the first P channel FET and the first N channel FET are turned off,
wherein electrons flow from the positive terminal of the second secondary cell battery to the terminal B of the coil and also flow from the terminal A of the coil to the negative terminal of the second secondary cell battery by back-emf which occurs to the coil, and
wherein the routine A is repeated while the first permanent magnet faces the L side of the coil,
routine B: ① both the second P channel FET and the second N channel FET are turned on and so the coil is activated by the second secondary cell battery, and ② both the second P channel FET and the second N channel FET are turned off,
wherein electrons flow from the positive terminal of the first secondary cell battery to the terminal A of the coil and also flow from the terminal B of the coil to the negative terminal of the first secondary cell battery by back-emf which occurs to the coil, and
wherein the routine B is repeated while the second permanent magnet faces the L side of the coil.
In the present invention, two permanent magnets and one coil and two secondary cell batteries are used to rotate a shaft and the power consumption of secondary cell batteries can be reduced by using back-emf which occurs to the coil. Also, the secondary cell batteries are charged by the rotating permanent magnets if the shaft rotates without using the secondary cell batteries.

If the shaft rotates clockwise, then secondary cell battery-2 (302) is charged as permanent magnet-1 (101) faces a side L of the coil (201) and secondary cell battery-1 (301) is charged as permanent magnet-2 (102) faces the L side of the coil (201).
FIG. 2 is a perspective view that illustrates a configuration of an apparatus for operating as DC generator and DC motor according to an embodiment of the present invention. FIG. 3 is a drawing that illustrates a rotating component to be used for passing and blocking light of photointerrupters. FIG. 4 is an electronic circuit of a device for making electric current flow in the coil.
As shown in FIG. 2, one rotating component (401) is placed on the shaft and is fixed with the unillustrated fixing means. One device (501) which implements photointerrupters and other electronic components is used to make electric current flow in the coil.
The rotating component (401) passes the light for 25° of angular separation and block the light for 25° of angular separation and this process is repeated 3 times and then block the light for 210° of angular separation.
The rotating component (401) is used to connect the positive terminal of secondary cell battery-1 (301) to the terminal A of the coil (201) and disconnect them, and is used to connect the negative terminal of secondary cell battery-1 (301) to the terminal B of the coil (201) and disconnect them, and is used to connect the positive terminal of secondary cell battery-2 (302) to the terminal B of the coil (201) and disconnect them, and is used to connect the negative terminal of secondary cell battery-2 (302) to the terminal A of the coil (201) and disconnect them.
The photointerrupter-1 (13) is set to pass the light of photointerrupter-1 (13) and then block the light of photointerrupter-1 (13) by the rotating component (401) as permanent magnet-1 (101) faces the L side of the coil (201).
The photointerrupter-2 (23) is set to pass the light of photointerrupter-2 (23) and then block the light of photointerrupter-2 (23) by the rotating component (401) as permanent magnet-2 (102) faces the L side of the coil (201).
A device (501) makes electric current flow in the coil (201) by changing the direction of electric current alternately. As shown in FIG. 4, if permanent magnet-1 (101) faces the L side of the coil (201), then the light of photointerrupter-1 (13) is passed through, P channel FET-1 (14) and N channel FET-1 (15) become ON, electrons flow from the negative terminal of secondary cell battery-1 (301) to the positive terminal of secondary cell battery-1 (301) and the coil (201) activates. Then after a while if the light of photointerrupter-1 (13) is blocked, then P channel FET-1 (14) and N channel FET-1 (15) become OFF and electrons do not flow from the negative terminal of secondary cell battery-1 (301) to the positive terminal of secondary cell battery-1 (301). At this time, back-emf occurs to the coil (201) and electrons flow from the positive terminal of secondary cell battery-2 (302) to the negative terminal of secondary cell battery-2 (302). The above routine is repeated 3 times while permanent magnet-1 (101) faces the L side of the coil (201). If permanent magnet-2 (102) faces the L side of the coil (201), then the light of photointerrupter-2 (23) is passed through, P channel FET-2 (24) and N channel FET-2 (25) become ON, electrons flow from the negative terminal of secondary cell battery-2 (302) to the positive terminal of secondary cell battery-2 (302) and the coil (201) activates. Then after a while if the light of photointerrupter-2 (23) is blocked, then P channel FET-2 (24) and N channel FET-2 (25) become OFF and electrons do not flow from the negative terminal of secondary cell battery-2 (302) to the positive terminal of secondary cell battery-2 (302). At this time, back-emf occurs to the coil (201) and electrons flow from the positive terminal of secondary cell battery-1 (301) to the negative terminal of secondary cell battery-1 (301). The above routine is repeated 3 times while permanent magnet-2 (102) faces the L side of the coil (201).
As permanent magnet-1 (101) faces the L side of the coil (201) as shown in FIG. 2, secondary cell battery-1 (301) is discharged and electric current flows in the coil (201). By back-emf which occurs to the coil (201), electric current flows in the coil (201) and secondary cell battery-2 (302) is charged. While electric current flows in the coil (201), permanent magnets rotate clockwise and so permanent magnet-2 (102) faces the L side of the coil (201).
As permanent magnet-2 (102) faces the L side of the coil (201), secondary cell battery-2 (302) is discharged and electric current flows in the coil (201). By back-emf which occurs to the coil (201), electric current flows in the coil (201) and secondary cell battery-1 (301) is charged. While electric current flows in the coil (201), permanent magnets rotate clockwise and so permanent magnet-1 (101) faces the L side of the coil (201).
Namely, by using two secondary cell batteries (301, 302) and changing the direction of electric current of the coil (201) alternately, permanent magnets rotate continuously and the secondary cell batteries are charged by back-emf which occurs to the coil.
The present invention is not limited to the embodiments of the present invention that are described herein and it should be clear to those who have general knowledge in the technical area related to the present invention that various changes can be made without departing from the scope of the technical thoughts of the present invention.
