In order to illustrate the working principle of the invention, it is illustrated below with reference to Fig. 1 to Fig. 4.
If permanent magnetic rotor two sides number of pole-pairs is pPM, speed VPM, starting phase angle θPM, then permanent magnetic rotor is formed
The permanent magnetism magnetomotive force F moved in the axial directionPM(θ, t) is represented by
F in formulak--- each harmonic magnetomotive force amplitude；
K --- permanent magnetism magnetomotive force overtone order；
θ --- mechanical angle；
T --- the time.
If the magnetic conduction block number for modulating mover two sides is pm, speed Vm, starting phase angle θm, then mover effect is modulated
Under the space that changes over time be represented by than magnetic conductance λ (θ, t)
λ in formula0、λi--- each harmonic is than magnetic conductance amplitude；
I --- harmonic ratio magnetic conductance number.
The permanent magnetic field moved in the axial direction that permanent magnet magnetic kinetic potential generates under modulation mover effect is represented by
B in formulak--- natural harmonic field amplitude, and Bk=Fkλ0；
Bk,i--- modulation harmonic field amplitude, and Bk,i=Fkλi。
By formula (3) it is found that two class magnetic fields will be generated under permanent magnetic rotor and the collective effect of modulation mover.The first kind is certainly
The characteristics of right harmonic field, such magnetic field is its magnetic field number of pole-pairs and speed and the magnetomotive number of pole-pairs of permanent magnetic rotor and speed
Identical, the amplitude in such magnetic field is Bk.Second class is modulation harmonic field, the characteristics of such magnetic field be it magnetic field number of pole-pairs with
Permanent magnetic rotor number of pole-pairs and magnetic conduction block number in modulation mover are related, its magnetic field speed also with permanent magnetic rotor and modulate both movers
Speed it is related, the amplitude in such magnetic field is Bk,i, it is as follows:
pk,j=| kpPM+jpm| (4)
J=0, ± 1, ± 2 ... (6)
P in formulak,j、Vk,j--- the number of pole-pairs and synchronizing speed of modulation harmonic field.
According to principle of electromechanical energy conversion it is found that only under the number of pole-pairs and speed same case in two magnetic field, ability
Constant thrust is generated, to realize energy converting between mechanical.Therefore, the first stator winding 5-1 is designed to by winding arrangement
It can produce the armature field of identical as modulation harmonic field number of pole-pairs and speed.So, the first stator winding 5-1, modulation mover
The double acting sub- linear motor of magnetic field modulation type is just constituted with permanent magnetic rotor.In this case, it acts on modulation mover
Electromagnetic push is equal to the sum of the electromagnetic push of the two for acting on stator and permanent magnetic rotor, and their electromagnetic push direction phase
Instead.Meanwhile modulating the thrust relationship between mover and permanent magnetic rotor and between modulation mover and the first stator winding 5-1 always
It is proportional.In addition, the armature field speed that the first stator winding 5-1 is generated is equal with modulation harmonic field speed, therefore,
It can refer to formula (5) to be adjusted the speed.Therefore, by modulating under the first stator winding 5-1, modulation mover and permanent magnetic rotor interaction
Mover and permanent magnetic rotor can only realize that speed decouples, but the thrust between them is still coupling.In practical applications, if only
Using a set of winding (the first stator winding 5-1), then the uncertainty due to wave motion will make the voltage of winding sending
It is extremely unstable.
The second stator winding 5-2 further be can produce into number of pole-pairs identical as natural harmonic field by winding arrangement design
With the armature field of speed.So, the second stator winding 5-2 and permanent magnetic rotor just constitute a permanent magnetic linear synchronous motor.
At this point, the second stator winding 5-2 is only acted on permanent magnetic rotor and is generated thrust, without generating thrust with modulation mover.Further, since
The armature field number of pole-pairs that first stator winding 5-1 and the second stator winding 5-2 is generated is different, therefore will not generate between them
In other words, between them thrust will not have an impact.Therefore, it is interacted by the second stator winding 5-2 and permanent magnetic rotor,
The thrust decoupling of modulation mover and permanent magnetic rotor can be achieved.
By above-mentioned analysis it is found that the electromagnetic push on modulation mover is only related to the first stator winding 5-1, mover is modulated
Speed is related to the speed of the armature field of the first stator winding 5-1 and permanent magnetic rotor；And electromagnetic push is not only in permanent magnetic rotor
It is related to the first stator winding 5-1, and influenced by the second stator winding 5-2, while the speed of permanent magnetic rotor and second
The armature field speed of stator winding 5-2 is identical.Therefore, plate for the double acting sub- double winding based on unilateral Excitation principle straight
For line generator, the thrust and speed of the thrust and speed and permanent magnetic rotor of modulating mover are completely independent.In addition, the motor is
Unilateral magnetic force is not present in motor for symmetrical structure.
In practical applications, modulation mover is connected with Wave-driven device, therefore modulates the movement of mover with very big
Randomness.At this point, making p-m rotor thrust and speed be effectively controlled by the second stator winding 5-2, to make first to determine
The speed of sub- winding 5-1 armature field remains constant, and then makes the double acting sub- double winding plate based on unilateral Excitation principle
The voltage magnitude of type linear electric generator sending, frequency remain constant, mention entire electricity generation system power generation quality significantly
It rises.
Concretely, the number of pole-pairs of permanent magnetic rotor is 6 in Fig. 1, and modulating protrusion unit number in mover is 10.It can by formula (4)
Know, a series of modulation harmonic field can be generated in air gap.In these modulation harmonic fields, when usually k=1, j=-1 pair
The modulation harmonic field amplitude maximum answered, that is to say, that 4 pairs of pole field amplitude maximums in modulation harmonic field.Therefore, by first
Stator winding 5-1 can produce 4 pairs of Polar armature magnetic fields by winding arrangement design, and (the first stator winding 5-1 is with axis as shown in Figure 3
Line plane is that the plane of symmetry is symmetrical, and it is the winding layout viewing of any side in figure that the winding arrangement of symmetrical two sides is identical).And
It is identical by the speed and 4 pairs of poles modulation speed of harmonic field of control the first stator winding 5-1 generation armature field, to make
First stator winding 5-1, modulation mover and permanent magnetic rotor realize energy converting between mechanical.
It will also realize that at this time by formula (3), a series of natural harmonic field can be generated in air gap, these natural harmonic fields are worked as
In, when k=1 corresponding natural harmonic field amplitude maximum, that is to say, that permanent magnetic rotor generates the natural harmonic field width of 6 pairs of pole
Value is maximum.Therefore, the second stator winding 5-2 be can produce into 6 pairs of Polar armature magnetic fields by winding arrangement design, as shown in Figure 4 (the
Two stator winding 5-2 are symmetrical by the plane of symmetry of axial plane, and it is any side in figure that the winding arrangement of symmetrical two sides is identical
Winding layout viewing).And the speed and 6 pairs of extremely natural harmonic fields of armature field are generated by the second stator winding 5-2 of control
Speed it is identical, then the second stator winding 5-2 and permanent magnetic rotor achieve that energy converting between mechanical.
Further, since the armature field number of pole-pairs difference (one that the first stator winding 5-1 and the second stator winding 5-2 is generated
A is 4 pairs of Polar armature magnetic fields, the other is 6 pairs of Polar armature magnetic fields), it will not be produced according to principle of electromechanical energy conversion, between them
Raw thrust.In other words, it can't interact between them.
Final effect is equivalent to, and the first stator winding 5-1, modulation mover and permanent magnetic rotor are a double acting sub-motors；
And the second stator winding 5-2 and permanent magnetic rotor are equivalent to traditional permanent magnetic linear synchronous motor.In this way, passing through the first stator winding
Modulation mover and the decoupling of permanent magnetic rotor speed can be achieved in the control of 5-1, but the thrust of the two is coupling (not being independent)；Into
The thrust decoupling between modulation mover and permanent magnetic rotor can be achieved by the control of the second stator winding 5-2 for one step.Therefore, in reality
Effective control to permanent magnetic rotor is realized by the second stator winding 5-2 in the application of border, even if in the modulation random speed change of mover
Also voltage magnitude, frequency-invariant that the first stator winding 5-1 is issued be can guarantee under movement, to make the power generation of entire electricity generation system
Quality is improved, and the stability for also running system is improved.In addition, the motor is symmetrical structure, it is not present in motor
Unilateral magnetic force.
