Description
The present invention relates to a kind of magnetic-energy generator that utilizes permanent magnet poles magnetic energy storage to produce electric energy.
Existing permanent magnet generator is a permanent magnetic linkage system, the magnetic energy storage of permanent magnet remains unchanged in the course of the work, magnet magnetic energy storage does not outwards discharge, permanent magnet field only is the media that mechanical energy is converted to electric energy, between armature coil and permanent magnet relative motion is arranged in the permanent magnet generator, the main flux of armature coil linkage is an alternation, so needing extraneous input mechanical energy to overcome mutual inductance moment between armature supply and magnetic field, just to keep spinner velocity constant, can prove that the output electric energy equates with input mechanical energy, so permanent magnet magnetic energy storage does not obtain utilizing.
The objective of the invention is to make full use of permanent magnet poles magnetic energy storage, provide a kind of the magnetic energy storage is converted to the novel electricity generator of electric energy, be the human being's production cheap electric energy.
The present invention realizes according to following opinion: according to the theory of relativity, if an object is emitted energy △ E, no matter form of energy how, its quality will reduce △ m=(△ E)/(C2) (the m-quality .C-light velocity in the formula), △ E can be mechanical energy, heat energy, luminous energy, electric energy, magnetic energy or any other form energy, when managing to make magnetic pole emit magnetic energy, the magnetic pole quality will reduce, and promptly the quality conversion of magnetic pole is an energy.
There is the magnetic energy storage permanent magnet poles inside, make permanent magnet poles emit magnetic energy and should satisfy following conditions:
1, system should be permanent magnetic potential system, and permanent magnet poles coercive force gesture is that normal value is constant, and the magnetic flux of permanent magnet poles and inner magnet energy storage change with the magnetic circuit magnetic resistance change rate.
2, magnetic resistance is to change in the cycle, rotor error angle θ=± magnetic resistance that the stator and rotor magnetic circuit is located in π point and θ=0 differs and is the bigger the better.
3, be provided with armature coil with the magnetic flux linkage in the magnetic circuit, the main flux direction of armature coil linkage is constant, cycle changes but size is with the rotor rotation, should not have relative displacement between coil and permanent magnet poles, can only be converted to electric energy output to guarantee magnetic energy.
4, the armature supply direction should be the degaussing direction, just thinking promptly that (π＜θ＜0 interval) just makes in the magnetic resistance half cycle from large to small flows through electric current in the armature winding, the magnetic energy of magnetic pole becomes electric energy and is exported by coil, and be zero at the interval armature winding electric current of 0＜θ＜π, coil power is zero, and magnetic pole does not absorb external enwergy and do not increase magnetic yet.
5, for making the rotor rotation steadily, drive motors power minimum should adopt the multisection type magnetic structure, to guarantee that when electric current in the armature coil is zero the resultant moment on the armature spindle is zero.When in the armature coil electric current being arranged, drive motors only need overcome the unbalanced moments that armature reaction produces.
6, the magnetic potential of armature coil electric current generation is the bigger the better, but exceeds not make permanent magnet poles produce permanent demagnetization.
The electric energy Wd that produces in armature coil when 7, rotor rotates should be greater than the mechanical energy W that keeps the rotor rotation
J, i.e. Wd/W
J＞1.
8, the big more performance index of high-output power are good more more for the magnetic-energy generator spinner velocity.
How further describe invention below in conjunction with drawings and Examples (is example with the 3000 rev/mins of magnetic-energy generators in the three-phase ends of the earth) realizes.

Fig. 6 is a basic circuit diagram of the present invention
With reference to Fig. 1, (6) be drive motors, the effect of drive motors has two, the one, with the magnetic-energy generator rotor from the static rated speed that accelerates to, the 2nd, keep when the magnetic-energy generator spinner velocity is constant outwards exports electric energy because of magnetic-energy generator, load current will produce the moment of resistance, and mechanical losss such as bearing friction and windage loss also produce the moment of resistance, and must importing mechanical energy by drive motors, the driving of just to keep spinner velocity constant. magnetic-energy generator electricity tip circle send the saddle cloth Duo ǖ that more stretches tight to shelter to let out the entangled black of the word nose section of rose to stop to send violent to fall Duo F myna and clap the black of lush ⒌ and protect the saddle cloth Duo that stretches tight) after spinner velocity reaches normal speed, handle switching control (4) through switching control (4) by batteries (5) power supply (can replace batteries with fairing when utility power is arranged) and will drive dc motor (6) and connect fairing (2) to magnetic-energy generator; Drive dc motor (6) by magnetic-energy generator (1) power supply itself, consume the part electric energy of magnetic-energy generator (1).
Rectifying device (2) is made up of unidirectional semiconductor power device, the AC rectification that magnetic-energy generator armature winding is produced becomes direct current, guarantee that every phase armature winding only flows through the pulse current that pulsewidth is π or (2 π)/(m) (when number of phases m 〉=3) in the half period that makes the permanent magnet poles demagnetization, so after electric loading (3) should be connected on rectifying device (2).
Available unidirectional controllable semiconductor power device of switching control (4) (as controllable silicon, high power transistor, high-power FET, turn-off SCR etc.) or relay-contactor are formed.Look use occasion and switching control (4) need be designed to manual operation or automatic control equipment, also can adopt the constant speed adjusting device in case of necessity.
In magnetic-energy generator longitudinal profile Fig. 2, as seen there are three sections annular stator core (10) to be assemblied in the casing (9), permanent magnet poles (11) then is contained between conducting magnet core (12) and the stator core (10), and armature coil (13) is sleeved on conducting magnet core (12) and locates.Rotor core (14) has three sections to be contained on the armature spindle (15) equally, and aligns with each section stator core (10) respectively.Axle (15) is by the supporting of the bearing on the two ends end cap (8), and shaft coupling (7) then is associated in drive motors (6) with armature spindle (15).
Fig. 3, Fig. 4 illustrate permanent magnet poles radial arrangement structure, and Fig. 5 illustrates permanent magnet poles (11) arranged tangential structure.Correlation between stator core (10), permanent magnet poles (11), conducting magnet core (12) (only the radial arrangement structure has) armature coil (13) is further clear illustrating in Fig. 3, Fig. 4, Fig. 5.The available high magnetic conduction punching silicon-steel closed assembly of stator core (10) and conducting magnet core (12) forms.The available neodymium iron boron of permanent magnet poles (11), Rare-Earth Cobalt or other high performance permanent magnetic materialses are made.Stator core (10), the also available mechanical means of available high-strength adhesive bonding tightens up between permanent magnet poles (11), conducting magnet core (12) three.

The narration magnetic-energy generator produces electric energy and the principle of keeping the rotor continuous running below.
In the magnetic-energy generator, the magnetic pad of permanent magnet poles is a fixed value, (rotor error angle θ=0 stable equilibrium point) magnetic circuit magnetic resistance minimum when rotor magnetic pole center and magnetic pole of the stator center-aligned, linkage magnetic flux maximum in energy storage maximum, the armature winding in magnetic flux maximum, the magnetic pole.When rotor center and magnetic pole of the stator center-aligned, (θ=± π, unstable equilibrium point) magnetic circuit magnetic resistance maximum, magnetic flux minimum, energy storage minimum in the magnetic pole, linkage magnetic flux minimum in the armature winding.Therefore when rotor rotate, though in the armature winding linkage magnetic flux direction constant young pathbreaker's cycle changes apricot Φ bridal veil beer W glaze tomb π＜θ＜0 greatly) interval, permanent magnet poles attraction rotor applies moment of accelerating T to rotor

Because magnetic-energy generator is the m system that balances each other, a utmost point only examining or check A phase rotor for simple meter from θ=-π to θ=0(strict in fact for θ=-(5 π)/6 to θ=-(π)/6 interval) interval energy conversion relation.θ=-during π, the magnetic flux of A phase armature coil linkage is a minimum value, when the magnetic flux that rotor rotates forward that the magnetic circuit magnetic resistance reduces gradually, energy storage increases gradually with the armature coil linkage in the magnetic pole increases gradually, in armature coil, produce the every utmost point number of turn of induced potential We(W-, e-circle electromotive force).This moment will be if the armature coil external circuit then will produce current i through the overload closure, according to Lenz's induction law, the armature coil sense of current is for stoping the growth of magnetic flux in the armature coil, be that the magnetic pad Wi that armature supply produces is a demagnetization magnetic potential, value when it will make the interior magnetic flux of magnetic circuit not have electric current to be lower than increases gradually, has part magnetic energy to be converted to electric energy output in this process.Attraction between magnetic pole of the stator and rotor pole also reduces because of magnetic flux weakens to some extent simultaneously, and moment of accelerating mean value is reduced to T
' +(it is relevant with current waveform shape and size that moment reduces degree).Owing to be three phase half wave rectification, when the A phase winding flows through electric current, there is not electric current in B phase, the C phase winding, so B section and C section magnetic pole of the stator retarding moment that rotor pole is produced and still be T
-(the three-phase resultant moment is not zero when having electric current) then moment balance no longer on the armature spindle, mean deceleration moment T
