Description

[0001] The present invention relates to a direct current (DC) motor which continuously rotates an axis without consuming almost any DC power inputted thereto,

The present invention relates to a DC motor, and more particularly, to a DC motor that continuously rotates a rotary shaft while using almost no DC power inputted to rotate the rotary shaft by operating an electromagnet using a DC power source.

An example of a conventional DC motor uses a permanent magnet and an electromagnet to make a rotor and a stator, and a direct current power source is used to operate the electromagnet and a direct current power source is continuously consumed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a DC motor that continuously rotates a rotary shaft without using almost any DC power input to the motor.

In order to attain the above object, the present invention provides an electric power generator comprising a permanent magnet installed on a shaft, two electromagnets provided opposite to the electromagnets installed on the outside of the permanent magnet, a direct current power source supplying direct current to the electromagnet, Lt; RTI ID = 0.0 > and / or < / RTI >

In the present invention, a permanent magnet is provided on a rotary shaft, and one pole of the magnet faces the outside and the other pole of the magnet faces the outside of the opposite pole. Two electromagnets are installed on the outside of the permanent magnet and two other electromagnets are installed on the opposite side. For each electromagnet, one end of each electromagnet wire is connected to the cathode of one diode and the other end of the wire is connected to the anode of this diode. The two electromagnets installed on both sides are installed so that the direction of the current is opposite. One of the two electromagnets installed, one of the two electromagnets installed on the opposite side of the electromagnet, the current flows through the electromagnet. When the permanent magnet rotates to reach the two electromagnets, current flows to the other two electromagnets so that the permanent magnet continues to rotate.

When a current flows through the electromagnet, the direct current is connected to the electromagnet and is interrupted. This connection / disconnection is repeated continuously. When the DC power source is connected to the electromagnet, the anode of the DC power source is connected to the cathode side of the diode of the electromagnet and the cathode is connected to the anode side of the diode. When a DC power source is connected to the electromagnet, a current flows through the electromagnet and a back-emf occurs in the electromagnet. The direction of the generated counter electromotive force is opposite to the direction of the current from the DC power source, and the voltage of the counter electromotive force is relatively higher than the voltage coming from the DC power source. When the direct current power is cut off in the electromagnet, the direction of the back electromotive force generated is reversed, and current flows to the electromagnet in the same direction as the direction from the direct current power source, and the electromagnet becomes stronger as the magnetic field of the electromagnet is relatively larger than that when the direct current power is connected . When the DC power is connected to the electromagnet again, the back electromotive force is generated again, and when the DC power is cut off from the electromagnet, the counter electromotive force which changes the direction makes the electromagnet strong. Therefore, the DC power supply acts as a trigger for generating the back electromotive force and the power consumption in the DC power supply hardly occurs.

As a result, the power consumption becomes almost zero in the DC power source, and the electromagnet becomes the DC motor which continuously rotates the shaft provided with the permanent magnet.

The present invention can provide a DC motor that continuously rotates a rotary shaft without using almost any DC power input to the motor.

As shown in Figs. 1 and 2, two permanent magnets 10 and 11 are provided on the rotating shaft, four electromagnets 20, 21, 22 and 23 are provided outside the permanent magnet, and a direct current A power source 30 is used and a connecting / disconnecting device 40 including a photoelectric sensor for connecting and disconnecting a DC power source to the electromagnet is used.

The N pole of the permanent magnet -1 10 faces the electromagnet, and the S pole of the permanent magnet -2 11 faces the electromagnet. For each electromagnet, one end of each electromagnet wire is connected to the cathode of one diode and the other end of the electromagnet wire is connected to the anode of this diode. When the current flows through the electromagnet-1 20 and the electromagnet 3 22 as shown in FIG. 1, the N pole of the electromagnet-1 20 faces the permanent magnet and the S pole of the electromagnet- (10) and the permanent magnet (2) (11) facing each other. When the current flows through the electromagnet 4 and the electromagnet 2 as shown in FIG. 2, the S pole of the electromagnet 4 23 faces the permanent magnet, and the N pole of the electromagnet 2 21 becomes the permanent magnet (11) and the permanent magnet (1) (10) facing each other.

The connection / disconnection device 40 serves to connect and disconnect the DC power supply 30 to the electromagnets 1, 2, 3, and 4 (20, 21, 22, and 23). When the permanent magnet-1 (10) and the permanent magnet-2 (11) reach the position shown in FIG. 1, the DC power is connected to and disconnected from the electromagnet-1 (20) and the electromagnet- Is repeated continuously. When the permanent magnets 1 and 10 reach the edges of the electromagnet 2 and the electromagnet 4 and 23 respectively, Do not connect the power any more. When the permanent magnets 1 and 10 are out of the edges of the electromagnet 3 and 22 and the electromagnet 1 and 20 respectively, Repeat this connection / disconnection continuously to connect and disconnect power. When the permanent magnets -1 and 10 reach the edges of the electromagnets 4 and 23 and the electromagnet 2 21, respectively, the electromagnets 4 and 23 and the electromagnet- Do not connect the power any more. When the permanent magnets -1 and 10 are deviated from the edges of the electromagnet 1 and the electromagnet 3 22 respectively, Repeat this connection / disconnection continuously to connect and disconnect power. When a DC power source is connected to each electromagnet, the anode of the DC power source is connected to the cathode side of the diode of each electromagnet and the cathode is connected to the anode side of the diode.

By making the electromagnet strong by using the counter electromotive force generated by connecting the DC power to the electromagnet and then blocking it, and by continuously repeating the connection / disconnection, the DC power serves as a trigger for generating the counter electromotive force, Continue to rotate the permanent magnet.
