Description

device for self-generating a driving force

technical field

The present invention relates to a device for self-generating a driving force, more particularly a device for using electromotive force generated on a coil by electromagnetic induction, and the device is combined with a mechanical driving device to drive the axis of rotation.

Background technique

Generally, a driving force generating device generates driving force using energy such as fuel, fire, water, wind, solar energy, or nuclear energy to drive a rotating shaft of a mechanically driven device.

However, under conditions where these energies have been increasingly depleted and contamination of most energies has inevitably increased, there is a need to develop a device capable of self-generating driving force, which is low-cost and very simple, while avoiding contamination such as nuclei or Many inconvenient issues due to weather effects on solar energy, etc.

Generally, according to Faraday's law of electromagnetic induction, when magnetic induction starts to act on a conductor, an electromotive force can be induced. The induced emf is generally proportional to the relative velocity of motion between the magnetic source and the conductor. Furthermore, it is well known that according to Lorentz's law, when the relative moving speed between the magnetic source and the conductor is changed so that the magnetic flux changes to generate electromotive force, a new magnetic field can be generated and a new electromotive force opposite to the electromotive force generated by the previous magnetic field can also be generated. force.

FIG. 1 is a schematic diagram showing the principle of electromagnetic induction according to Faraday's law and Lorentz's law. As shown in Figure 1, when the magnet 1 moves relative to the coil 2 with a velocity v and affects the coil 2, the induced magnetic field on the coil 2 changes due to the coil 2 crossing the magnetic field line, so according to Faraday's law, the induced electromotive force and the resulting The induced current can be generated by the coil 2, where the induced current I is proportional to the magnetic field strength and the relative moving speed v. And, according to Lorentz's law, the induced electromotive force can cause the coil 2 to generate a force F that prevents the change of the magnetic field of the magnet 1, wherein the opposite force F (for example, the opposite electromotive force) is obtained by combining the magnetic flux density B of the magnet 1 and the induced current I and The total length L of coil 2 is multiplied to obtain, for example,

F＝k.B.I.L (k is a constant)

Thus, an opposing force F can continue to induce another force F'.

Therefore, if the opposite force F (and/or force F') can be effectively combined with the mechanical drive device to drive the rotating shaft, and the forces F and F' are much greater than the net frictional force, the initial initiation of rotation by the external force for a short time After the shaft, the rotating shaft can continue to rotate without any external force, so it can generate kinetic energy.

Detailed ways

Referring to FIG. 2 , FIG. 2 is a schematic structural diagram showing a device for self-generating driving force according to a preferred embodiment of the present invention. As shown in FIG. 2, according to the present invention, the means for autonomously generating driving force includes a mechanical driving device. The mechanical drive device comprises a rotating shaft A on which at least a set of double cantilever arms 11, 12 are included: the cantilever arms 11 and 12 can be separate parts or can also be individually connected to the shaft. The number of cantilevers 11, 12 is not limited by the description of the figures. Preferably, the number of cantilever arms 11, 12 can be plural, and they are each arranged symmetrically on the axis A at a predetermined angle. The cantilevers 11, 12 are preferably welded to the axis of rotation A vertically and/or at a predetermined angle. A magnet 31, 32 is attached to one end of each cantilever. Preferably, the magnets 31, 32 comprise a permanent magnet material. Each magnet 31 , 32 has the same polarity orientation, wherein these orientations lie in the direction of the respective cantilever 11 , 12 . The device further comprises at least one set of double coils 21 , 22 fixedly mounted at the same angle as the predetermined angle of the cantilever arms 11 , 12 . In this embodiment, the number of coils corresponds to the number of cantilevers. However, the number of coils is not limited to the description of the drawings. One opening of each coil 21 , 22 faces the axis A perpendicularly. As shown, two winding terminals b, d respectively located at the opening of each coil 21, 22 are connected to each other by a switching element, such as transistor Q1, and the other two windings respectively located at the other opening of each coil 21, 22 Terminals a, c are directly electrically connected.

Figure 3 shows a more general circuit. The switching element 30 may be a transistor, a relay, an optocoupler device, a Hall effect device, or any other switching element.

The following description will clarify the operation of the device according to the invention. As shown in FIG. 2, when the magnet 32 passes through the opening of the coil 22, the coil 22 can induce an electromotive force E1. At the same time, the electromotive force E2 can also be induced by other magnets 31 that induce the current I1 on the coil 21 . The sense current I1 flows through the current limiter R2 and turns on the transistor Q1. Since transistor Q1 is turned on, current I2 flows through coil 22 . Then, the coil 22 can easily generate an opposite force (for example, an opposite electromotive force) to drive the cantilever to move in the S direction. Therefore, the rotary shaft A can be driven to rotate. Therefore, after initial activation of the shaft by the action of an external force applied for a short time, for example, by manual force, the rotary shaft A can continuously rotate in a predetermined direction without any external energy.

The coils 21 and 22 may be hollow or may have a core made of magnetically permeable material.

While preferred embodiments of the invention have been described, they do not limit the invention. Note that modifications and variations can be made by those skilled in the art in light of the above teachings. It will therefore be understood that various changes, substitutions of equivalents and modifications can be made in the specific embodiments of the invention without departing from the scope and spirit of the invention as defined by the appended claims.
