Embodiment

After magnetizing once based on permanent magnet, have need not impose any energy that adds and just can produce endlessly magnetic force and coil and not influenced by magnetic force and switch on after, the controllability of electromagnet polarity, and according to the power between Coulomb's law two magnetic fields, the product that is two magnetic poles is divided by square distance, but so need only make motor magnet produce magnetic force with a little electric power, the priming permanent magnet results from the active force that both produced between coil and the permanent magnet, the active force of being drawn can rely on coil or permeability magnetic material and magnet to be exported pushing generator generation electric power, and since the electric power that produced much larger than self employed electric power, so all the other electric power can be made for the usefulness of output except that a part of electric power uses voluntarily.

Please refer to Fig. 1 and Fig. 2, it is respectively the utility model in conjunction with monolateral permanent magnet structure schematic perspective view of permanent magnet electromagnetic actuator device tool and illustrative view.This has a permanent magnet 1, a magnetic conductor 2 and a coil 3 in conjunction with the permanent magnet electromagnetic actuator device.Wherein, this permanent magnet 1 is placed this magnetic conductor 2 on it, with usefulness as movable electromagnet core, and in these magnetic conductor 2 peripheral these coils 3 of placement, this magnetic conductor 2 is arranged on the side of this permanent magnet 1, and this coil 3 is sheathed on the periphery of this magnetic conductor 2 slidably.In the present embodiment, this coil 3 does not combine as traditional electrical magnet with this magnetic conductor 2, so imposing electric current in this coil 3 makes itself and this 1 contacted of permanent magnet produce the electric current that the same sex is repelled each other, so this coil 3 can produce active force along this magnetic conductor 2, the size of its power is to decide with this permanent magnet 1 and magnetic force that this coil 2 was produced size and distance according to Coulomb's law, but for to draw big active force with little electric power, general is main emphasis with the magnetic force that increases permanent magnet 1 all.Because, it need not consumed energy and also the active force of the big more sum total of its magnetic force big more.In the present embodiment, this permanent magnet can ferrite, neodymium iron boron or SmCo are made, yet not as limit; such as have once magnetize after; can be when not being subjected to external magnetic force, bump and temperature effect, the material of sustainable its magnetic force of maintenance is all in protection range of the present utility model.Moreover, in the present embodiment, this magnetic conductor 2 is made with the material that silicon steel sheet, silicon steel rod, pure iron, permalloy or non-crystalline material etc. have magnetic conductivity, and can be in when these coil 3 energisings the time, because of electrical interaction produces magnetic and magnetic pole, magnetic is scolded or the magnetic force of magnetic and magnetic pole that should permanent magnet 1 produced.

Please refer to Fig. 3, Fig. 4 and Fig. 5, it is bilateral permanent magnet start first schematic side view of electromagnetic actuator device, second schematic side view and the simple and easy schematic diagram of practical application of the utility model utilization permanent magnet magnetic force.For asking the potential energy of many primings of energy permanent magnet, so, the other end in this magnetic conductor 2 additionally increases another permanent magnet 4 again, so just can get one and push away a double reaction plus of inhaling, and the polarity of using this coil 3 to change input current can change the characteristic of its two ends polarity, to produce lasting piston motion, so just can use this coil 3 or this magnetic conductor 2 and this permanent magnet 1 and other this permanent magnet 4 that the active force of gained is exported generating.

See also Fig. 6, be the simple and easy schematic diagram of electromagnetic actuator device practical application of the utility model utilization permanent magnet magnetic force.After this coil 3 is subjected to electricity to produce magnetic force and this permanent magnet 1 and other this permanent magnet 4 reciprocations generation strength, the positive-negative polarity that the strength that is produced is imposed on a power transmission shaft 6 and control input power supply by a plate 5 to be producing the reciprocating-piston motion via a connecting rod 7 and then drive a generator 8 and produces electric power, and because the electric power that is produced much larger than the electric power of input use.So, behind the employed electric power of deduction itself, still have unnecessary electric power to use, and can constitute the generator of the quite high operational paradigm of a tool for output.
