In order to illustrate the operation principle of the present invention, said by taking structure shown in Fig. 1~Fig. 3, Figure 13~Figure 18 as an example below
It is bright.
If p-m rotor number of pole-pairs is pPM, rotating speed is ΩPM, starting phase angle is θPM, then the permanent magnetism that p-m rotor is formed
Magnetomotive force FPM(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 of modulation rotor is pm, rotating speed is Ωm, starting phase angle is θm, then under modulating rotor effect
Than magnetic conductance λ, (θ t) is represented by time dependent space
λ in formula0、λi--- each harmonic is than magnetic conductance amplitude；
I --- harmonic ratio magnetic conductance number of times.
The permanent magnetic field that permanent magnet magnetic kinetic potential is produced under modulation rotor effect is represented by
BPM(θ, t)=FPM(θ,t)λ(θ,t) (3)
B in formulak--- natural harmonic field amplitude, and Bk=Fkλ0；
Bk,i--- modulation harmonic field amplitude, and Bk,i=Fkλi。
From formula (3), two class magnetic fields will be produced under the collective effect of p-m rotor and modulation rotor.The first kind is
The characteristics of natural harmonic field, such magnetic field, is its magnetic field number of pole-pairs and rotating speed and the magnetomotive number of pole-pairs of p-m rotor and turns
Speed is identical, and the amplitude in such magnetic field is Bk.The characteristics of Equations of The Second Kind is modulation harmonic field, such magnetic field is its magnetic field number of pole-pairs
Related to magnetic conduction block number in p-m rotor number of pole-pairs and modulation rotor, its rotational speed of magnetic field also turns with p-m rotor and modulation ring
The son rotating speed of the two is related, and 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、Ωk,j--- the number of pole-pairs and synchronous angular velocity of modulation harmonic field.
It can be seen from principle of electromechanical energy conversion, only when under the number of pole-pairs and rotating speed same case in two magnetic field, ability
Constant torque is produced, so as to realize energy converting between mechanical.Therefore, the first stator winding 5-1 is designed to by winding arrangement
The armature field of number of pole-pairs identical with modulation harmonic field and rotating speed can be produced.So, the first stator winding 5-1, modulation ring turn
Son and p-m rotor just constitute the double-rotor machine of magnetic field modulation type, its concrete operating principle and Chinese patent
CN104377918A, CN104393726A are identical with the operation principle of the double-rotor machine scheme described in CN104377919A.
In this case, the electromagnetic torque acted on modulation ring is equal to the electromagnetic torque of the two for acting on stator and p-m rotor
Sum, and their electromagnetic torque is in opposite direction.Meanwhile, modulation rotor and p-m rotor between and modulation rotor and
Torque relationship between first stator winding 5-1 is proportional all the time.Additionally, the armature magnetic that the first stator winding 5-1 is produced
Field rotating speed is equal with modulation harmonic field rotating speed, therefore, referring to formula (5) carries out speed governing.Therefore, by the first stator winding 5-1,
Under modulation rotor and p-m rotor interact, modulation rotor and p-m rotor can only realize that rotating speed is decoupled, but they it
Between torque remain coupling.
Further the second stator winding 5-2 can be produced into number of pole-pairs identical with natural harmonic field by winding arrangement design
With the armature field of rotating speed.So, the second stator winding 5-2 and p-m rotor just constitute a permagnetic synchronous motor.Now,
Second stator winding 5-2 only produces torque with p-m rotor effect, and does not produce torque with modulation rotor.Further, since the
The armature field number of pole-pairs that one stator winding 5-1 and the second stator winding 5-2 are produced is different, therefore will not produce between them and turn
Square, in other words, will not produce impact between them.Therefore, interacted by the second stator winding 5-2 and p-m rotor, can
Realize the torque decoupler of modulation rotor and p-m rotor.
By above-mentioned analysis, the electromagnetic torque modulated on rotor is only related to the first stator winding 5-1, modulates ring
Rotor speed is related to the armature field of the first stator winding 5-1 and the rotating speed of p-m rotor；And electromagnetic torque on p-m rotor
It is not only related to the first stator winding 5-1, and affected by the second stator winding 5-2, at the same the rotating speed of p-m rotor only with
The armature field rotating speed of the second stator winding 5-2 is identical.Therefore, for unilateral adjustable magnetic profile shaft is to integrated form electric stepless speed change
For device, the torque rotary speed for modulating rotor is completely independent with the torque rotary speed of p-m rotor, which achieves from a machinery
Infinitely variable speeds work(of the port (modulation rotor or p-m rotor) to another mechanical ports (p-m rotor or modulation rotor)
Energy.
Compare the brushless compound machine side in Chinese patent CN104377918A, CN104393726A and CN104377919A
For case, the present invention can save torque regulation motor in these schemes, therefore, this programme is simpler than these scenario-frames,
Small volume, integrated level are high.
It is specific as follows with reference to Fig. 1~Fig. 3, Figure 13~Figure 18：
The number of pole-pairs of p-m rotor is 6 in Fig. 1~Fig. 3, and magnetic conduction block number is 10 in modulation rotor.From formula (4), gas
A series of modulation harmonic field can be produced in gap.In the middle of these modulation harmonic fields, typically k=1 is corresponding during j=-1
Modulation harmonic field amplitude maximum, that is to say, that 4 pairs of pole field amplitude maximums in modulation harmonic field.Therefore, by the first stator
Winding 5-1 can produce 4 pairs of Polar armature magnetic fields by winding arrangement design, as shown in Figure 13, Figure 14, Figure 17.And by control the
The rotating speed that one stator winding 5-1 produces armature field is identical with the rotating speed that harmonic fields are modulated in the 4 pairs of poles so that the first stator around
Group 5-1, modulation rotor and p-m rotor realize energy converting between mechanical.
Will also realize that by formula (4) simultaneously, a series of natural harmonic field can be produced in air gap, these natural harmonic fields are worked as
In, corresponding natural harmonic field amplitude maximum during k=1, that is to say, that p-m rotor produces the natural harmonic field width of 6 pairs of pole
Value is maximum.Therefore, the second stator winding 5-2 can be produced into 6 pairs of Polar armature magnetic fields by winding design of arranging, such as Figure 15, Figure 16,
Shown in Figure 18.And by controlling the second stator winding 5-2 the rotating speed of armature field is produced with 6 pairs of extremely nature harmonic wave harmonic fields
Rotating speed is identical, then the second stator winding 5-2 and p-m rotor achieve that energy converting between mechanical.
Further, since the armature field number of pole-pairs different (that the first stator winding 5-1 and the second stator winding 5-2 is produced
Individual is 4 pairs of Polar armature magnetic fields, and another is 6 pairs of Polar armature magnetic fields), according to principle of electromechanical energy conversion, will not produce between them
Raw torque.In other words, can't interact between them.Final effect is equivalent to the first stator winding 5-1, modulation ring
Rotor and p-m rotor are a double-rotor machines；And the second stator winding 5-2 and p-m rotor are same equivalent to traditional permanent magnetism
Step motor.So, modulation rotor and the decoupling of p-m rotor rotating speed, but two are capable of achieving by the control of the first stator winding 5-1
The torque of person is coupling (not being independent)；Further modulation rotor is capable of achieving by the control of the second stator winding 5-2
Torque decoupler and p-m rotor between.It is achieved thereby that modulating the solution completely of torque rotary speed between rotor and p-m rotor
Coupling.And in hybrid power system, exactly need the torque rotary speed for connecting two rotating shafts between electromotor and vehicle load complete
Decoupling.But it is characteristic of the invention that than conventional brushless composite structure motor (brushless double-rotor machine and one it is traditional
Motor is simply connected realization) simple and compact for structure, integrated level is much higher.
