Field of invention

The present invention relates to generators and motors using propagated oscillating magnetic field. In particular, the present invention relates to generators', rotary motors, sliding motors and swinging motors, in which the magnetic field are oscillating in the propagated way.

Background of invention

The humanity nowadays depends significantly on the fossil resources such as petroleum, coal and natural gas. Such resources are limited and their use is contributing to the global pollution. In diversifying the supplying resources, the power of magnetic field is found to be a clean and non-polluting one. A number of solutions are known to utilize the power of the magnetic field of permanent magnets in everyday life and to improve the devices using such this power resource.

U.S patents Nos. 6246561 and 6342746 Bl have provided methods of controlling the magnetic field of one or two permanent magnet(s) and the similar incorporated devices. According to these methods, the dual magnetic field (double) just oscillates in one or the other side of the controlling coils, from one or two permanent magnets which are connected in parallel in a closed magnetic circuit, i.e. the control coils according to this solution can generate the magnetic field to only co- attract or only co-push, or one coil pushes and the other attracts, in the magnetic field of the permanent magnet. Therefore, only one dual magnetic field is generated in response to one inlet pulse provided. Moreover, more power for controlling is needed in these methods since the deflection oscillated angle of magnetic field of permanent magnetic is 180°. Thus, the coefficient of performance and the force of the devices are still limited.

U.S patent No. 6946938 Bl provided methods and devices employing electromagnetic switches to open and to close the magnetic field. This solution also employs an open/close control circuit to control the electromagnetic switches so as to render the magnetic field of permanent magnets oscillating through the electromagnetic switch via the certain flux paths. The device also generates only single magnetic oscillation in the inducted coil. With the structure, the coefficient of performance and the force are still not high yet.

Details description of the prf erred embodiments

FIG. Ia is schematic view showing a generator using propagated oscillating magnetic field comprising a single magnetic circuit combination, the generator has two magnetic sources.

As shown in the drawing, a generator has two electromagnets El and E2, a single magnetic circuit unit comprising of two magnetic sources Pl and P2, and three magnetic circuit segments Rl, R2 and R3 which are positioned so that the pole surfaces of the adjacent magnetic sources have the same mark, one ends of three magnetic circuit segments are coupled to the pole surfaces of the magnetic sources and the other ends are coupled to each other thanks to the presence of the magnetic circuit segments R4 and R5 which are adjacently coupled to the poles of two electromagnets to form closed magnetic paths of the magnetic sources and the electromagnets.

Two output inductive coils Cl and C2 are provided on the magnetic circuit segment R4 .

Two electromagnets El and E2 are coupled to a power supply through an open/close control switch, for example a MOSFET circuit, so that their magnetic field are always parallel but in reverse directions each to the other. The dashed line in FIG. 1 shows the magnetic field is oscillating via C2 coil while no magnetic field affects Cl coil. The next electrical pulse generated as the control circuit toggles renders the magnetic field oscillating through the magnetic core of Cl coil, while C2 coil remains unaffected by any magnetic field. The magnetic field of the magnetic sources are oscillating in a flickering manner as a magnetic semiconductor, the oscillating frequency depends on the frequency of the open/close control circuit.

The magnetic field generated by the assembly of the electromagnets will interact with the magnetic field of the magnetic source creating the magnetic inductive oscillations and generating an electronic current on output inductive coils.

The oscillations of the magnetic field generate a magnetic inductive oscillation on Cl and C2 coils in accordance with the first Faradey law and Maxwell's formula as follows:

dø E = - W * dt wherein E denotes (EMF) inductive electromotive force, 0 denotes flux oscillating during the time t and W denotes the number turns of wire of the output coil, wherein 0 = B* A in which B is magnetic induction and A is the cross-section of the magnetic circuit.

The magnetic resources are used in a magnetic circuit combination could be, but not limited to, permanent magnets (ferrite magnet, alnico magnet, NdFeB magnet...) or super-conductor magnets at room temperature.

FIG. Ib shows the principle of a generator comprising a single magnetic circuit combination. The operation of this embodiment is the similar to the above mentioned generator, but the number of magnetic sources is increased to three corresponding with six magnetic circuit segments and three output inductive coils.

FIG. Ic shows the principle of a generator comprising a single magnetic circuit combination with four magnetic sources corresponding with four output coils, seven magnetic circuit segments and the operation thereof is similar to that of the above mentioned embodiments.

As shown generally in FIG. Id, if the number of magnetic sources corresponding with the number of output inductive coils is equal to n in the magnetic circuit combination of a generator, the number of magnetic circuit segments would be (n+2) T/VN2010/000001 and a single magnetic circuit segment would close the magnetic field of two electromagnets, where n is a positive integer.

In order to further improve the output capacity and coefficient of performance, a propagated oscillating magnetic generator comprises of two electromagnets and twp identical magnetic circuit combinations, which are symmetrically positioned via two electromagnets.

As shown in FIG. 2a, when the electromagnets El and E2 are polarized, the magnetic field at S polar of El attracts the magnetic field at N polar of magnetic source Pl, while the magnetic field at N polar of El has the same direction of the magnetic field at N polar of magnetic source P4 and attracts the magnetic field at S polar of P3 magnetic source. At the same time, the magnetic field at S polar of electromagnet E2 attracts the magnetic field at N polar of P3 magnetic source while the magnetic field at N polar of E2 is parallel to the magnetic field N of magnetic source P2 and attracts the magnetic field at S polar of Pl magnetic source. At the next electrical pulse, the magnetic field oscillates similarly. The dual magnetic field of the magnetic sources always oscillates via the couples of output inductive coils Cl, C3 and C2, C4.

Similarly, FIG. 2b, FIG. 2c and FIG. 2d show how the propagated oscillating of magnetic field in closed magnetic circuit. Although the number of magnetic resources as well as that of closed magnetic circuits increase and the output coils can form rows which are symmetrical via two electromagnets, it is seen that the magnetic field of two electromagnets would only interact with the magnetic field of the first or the second magnetic resource at two ends of two consecutive rows of the magnetic circuits, and therefore the magnetic field of the consecutive magnetic sources will simultaneously interact with the magnetic field having the opposite mark of magnetic source spaced by a single magnetic source, generating a dual magnetic oscillation which is propagated in one direction of the common magnetic circuit segment within the magnetic circuit combination. The next electrical pulse provided by the open/close controling switch would render the magnetic oscilation doubled and propagated in the opposite direction.

In the light of the foregoing, it is observed that the number of permanent magnets in each magnetic circuit combination can increase while the power of two electromagnets need not increase correspondingly. Therefore, the magnetic field of the magnetic resources has the same direction in reply to each electronical pulse provided by the controling circuit, and the magnetic field has the opposite direction in reply to thp next electrical pulse, and therefor the balance of the magnetic field is secured. The magnetic resources arrangement in which each magnetic source is so coupled to the next magnetic resource that the same mark polars are faced to each other can render unlimited increase in the number of magnetic resources and the closed magnetic circuits which are positioned symmetrically via the electromagnets. Due to the self-balance of the magnetic field, it is needed to provide a minimum power supply to twp electromagnets, enough to sufficiently activate the magnetic field of the first magnetic resources and the last one, the remained magnetic resources will auto-oscillate and propagate with speed of the light between these magnetic sources. As a result, the total magnetic inductive power on the output inductive coils of the common magnetic circuit is (multiply) many times as much as the inlet power.

FIG. 3 a, FIG.3b and FIG. 3 c show the structure and the operation of the rotary motor using propagated oscillating magnetic field with four permanent magnets.

The embodiment comprises of a rotor firmly fixed on axle Q which is formed by at least two identical cicular discs C made of non-magnetic, the surface of the discs is provided with identical magnetic leaders M, which are equidistantly spaced by the circumferential of each disc, the magnetic leaders M of two adjacent discs are so positioned that they are equidistanly positioned between each other (see FIG. 3b).

As shown in FIG. 3a, rotor Q is longitudinally surounded by stator K. This stator comprises of two identical electromagnets El and E2 which are symmetrically positioned so that the magnetic field's directions of these two electromagnets are alway opposite each to the other; two magnetic circuit units are positioned symmetrically via two electromagnets El and E2 and via axle of rotor Cs discs, each magnetic circuit combination comprises of at least two magnetic sources Pl and P2, and three magnetic leading bars Tl, T2 and T3 are positioned so that the pole surfaces of the adjacent magnetic sources have the same mark, one ends of three magnetic leading bars Tl, T2 and T3 are coupled to the pole surfaces of magnetic sources Pl and P2, while the other ends having their section similar to that of the magnetic leaders M is directed towards rotor Cs discs so that these discs are positioned in between magnetic leading bars Tl to T3 .

In reply to a single oscillating pulse provided by the open/close controling switch, only the dual magnetic field will interact to a pole piece on each of rotor, i.p there are four units of the magnetic field B getting through the air gap to interact to a pair of pole piece on two rotor discs. Similarly, each following opposite electrical pulse will generate dual magnetic field interacting to a pair of the next facing pole pieces. These electromagnetic forces are in reverse direction each to the other and are calculated by the following formula:

B ² *A p =

2μ ₀ wherein B denotes the magnetic field, A denotes cross-section area of a polar pole and μ ₀ denotes air permeability and is constant.

The electromagnets all have their magnetic core made of high permeable materials such as nano-crystal, permaloyd, etc.

On FIG.3a, SPl and SP2 are the sub-paths which are designed to free the rotor from the attractive force of the magnetic resources P2, P4 and Pl, P3. These paths SP could be radically moved against the stator. Then, the magnetic field of the magnetic sources has the secondary closed path with smaller magnetic resistance and therefore they do not affect to the pole pieces at the rotor and consequently the rotor would freely rotate. The role of the coils SCl-I and SC 1-2 is, when being powered together with the electromagnets, to join the electromagnets in attracting the magnetic field of the magnetic sources Pl, P2, P3, P4 so that the sub-paths SPl and SP2 easily detach from the stator.

Operation of this motor repeats at a frequency dependent on the frequency of the open/close circuit. The attractive electromagnetic force keeps rotor Q rotating in a given direction notwithstanding that the inlet electrical pulse switches reversely or changes its frequency. The rotating direction of the rotor is determined by the positions of the cutoff on the magnetic pole peaks al-a2 (FIG. 3c), in which the magnetic field just affects from the pole piece bi via the magnetic boss M at a position A ₀ in the rotor's circumferential direction (at the magnetic pole peaks without any cut-off) as it has smaller magnetic resistance, to the pole piece b ₂ . This magnetic field always tends to pull magnetic boss M at a position A ₀ to position Ai in the arrow direction.

FIG. 4 shows the rotation of the motor in presence of a number of magnetic sources and corresponding magnetic circuit segments. The number of rotor discs equals to that of the magnetic resources.

FIG. 5 a is a cross-section view showing a sliding motor using the propagated magnetic field of the invention having a ram with two sliding rods.

As shown in the drawings, ram K formed by at least two identical sliding rods made of non-magnetic material (see FIG. 5b-5c), the surface of each sliding rod is provided with two rows of identical magnetic leaders M, which are equidistantly spaced along with the length of each rod so that they form a line in the side view, the magnetic leaders M of two adjacent rods are positioned enantiomerically with each other (see FIG. 5b-5c). This stator is similar to that of the above rotary motor and therefore will not be described in details herein. However, the cut-offs are provided at the magnetic pole peaks of the stator to identify the moving direction of the ram at the same side.

When electrical pulse is provided to an electromagnet, the magnetic field created by the electromagnet will interact with the magnetic field of the magnetic circuit unit in order to generate electromagnetic forces which are symmetrical and have the same direction, moving the ram. The path of the dual magnetic field is similar to that of above mentioned rotary motors.

FIG. 6a is the view showing a swinging motor using the propagated magnetic field of the invention, in which a swinger comprises of two swinging bars L. Two swing bars L are made of non-magnetic material, one ends of these bars are provided with magnetic leaders MDT ₅ which are deflected with an angle equal to one oscillation- length (see FIG. 6a).

FIG. 6a shows the swinger surrounded by the stator which is similar to stators of the above mentioned motors, comprising of two identical electromagnets El and E2 which are positioned symmetrically with each other via the oscillation plane of the swinger so that the magnetic field's directions of these two electromagnets are always reverse each to the other. Two magnetic circuit combinations are positioned symmetrically via two electromagnets and the axle center of the swinger, each magnetic 00001 circuit combination comprises of at least two magnetic sources Pl, P2 and P3, P4 and magnetic leading bars 11, 12, 13, and 14, 15, 16 are positioned so that pole surfaces of the adjacent magnetic sources have the same mark, one ends of triple of magnetic leading bars are coupled to the pole surfaces of the corresponding magnetic sources, while the other ends having their section similar to that of the magnetic leaders is directed towards the swinging bars L so that the swinging end of these rods are positioned in between magnetic leading bars. When provided with inlet electrical pulse, the magnetic field created by the electromagnets will interact with the magnetic field of the magnetic sources of the magnetic circuit unit in order to generate electromagnetic forces to render the swinger oscillating. The paths of the magnetic field in this motor are similar to that of the above mentioned rotary and sliding motors and therefore will not be described here.

While the above is a complete description of the preferred embodiments of the invention, various alternatives, modifications, and equivalents may be used. Therefore, the above description should not be taken as limiting the scope of the invention which is defined by the appended claims
