Figure, Fig. 4 are the transversary schematic diagram of the mover core of the dual-axle motor of the preferred embodiment of the present invention, and Fig. 5 is preferred for the present invention
The transversary schematic diagram of the stator core of the dual-axle motor of embodiment.Wherein, stator core 2 includes stator yoke 22 and stator
Eight stator poles 21 that yoke 22 inwardly protrudes out.In lateral cross section, the periphery of stator yoke 22 is square, is inside enclosed for ring
Shape.Each stator poles 21 protrude out to form five stator tooths 210 inwardly, and these stator tooths 210 axially extend.In each stator poles 21
Stator tooth 210 have fixing tooth away from.A cylindrical space is surrounded in these stator tooths 210.
On the corner of stator core 2, a through hole 20 is respectively offered.In the axial direction of first section 31, stage casing 32 and endpiece 34
Relative position also accordingly offers through hole.Four latches 30 through these through holes and are fixed stator core 2 and the phase of housing 3, and
Detachably.Thus then whole motor mould is changed soon, the length of motor in the axial direction can be suitably adjusted according to the size of axial load
Degree.In some other embodiments, latch 30 and corresponding through hole can at least reduce to two.
Mover core 1 and mover axle 4 are arranged in the cylindrical space.Mover core 1 includes mover yoke, the mover yoke

Mover tooth 10, i.e. mover tooth 10 also have fixing tooth away from.
The facewidth W2 of said stator tooth 21 is equal with the facewidth W1 of mover tooth 10, to cause positioning in the axial direction more smart
It is accurate.In some other embodiments, the facewidth W2 of stator tooth can also be unequal with the facewidth W1 of mover tooth.
The periphery of mover tooth 10 and the interior of stator tooth 210 form thin shape air gap between enclosing.The tooth pitch and stator of mover tooth 10
Angle of circumference corresponding to the tooth pitch of tooth 210 is identical, is constant θ0.Because air gap is very thin, thus the tooth pitch L of mover tooth 10pWith determining
The tooth pitch L ' of sub- tooth 210pIt is roughly the same.Or make the tooth pitch L of mover tooth 10 in some other embodimentspWith stator tooth 210
Tooth pitch L 'pIt is identical, and its distinguish corresponding to angle of circumference it is roughly the same.Fine difference caused by thin shape air gap can be ignored
Disregard.
Due to above-mentioned setting so that when any one stator tooth 210 in any one stator poles 21 and mover tooth 10 are same
Step ground or staggers face, i.e., when any one stator tooth 210 in any one stator poles 21 and any one mover tooth 10 just
Pair when, other all stator tooths 210 in the stator poles 21 with a face of mover tooth 10；When in any one stator poles 21
Any one stator tooth 210 and any one mover tooth 10 when staggering, other all stator tooths 210 in the stator poles 21 are equal
Stagger with a mover tooth 10.That is, all stator tooths 210 of a stator poles 21 with corresponding mover tooth 10 it
Between angulation θ it is identical.Referring to Fig. 6, " corresponding mover tooth 210 " refer to specified a certain stator tooth 210 with it is a certain
When mover tooth 10 is corresponding, the n-th stator tooth 210 of the clockwise direction side of the stator tooth 210 and the up time of mover tooth 10
The n-th stator tooth 210 of pin direction side is corresponding, and wherein N is positive integer.Such as in figure 6, as specified stator tooth 210a
When corresponding with mover tooth 10a, first stator tooth 210b and the mover tooth 10a up times of stator tooth 210a clockwise directions side
First mover tooth 10b of pin direction side is also corresponding, and can be by that analogy.Directly specify in other words according to identical up time
Pin or continuous (N+1) the individual stator tooth of counter clockwise direction are corresponding with (N+1) individual mover tooth, and these sayings are all equivalent.
Wherein, when the angle, θ is zero, i.e., so-called stator tooth 210 and the face of mover tooth 10；When the angle, θ is not zero,
I.e. so-called stator tooth 210 staggers with mover tooth 10.
Preferably, the tooth pitch L of mover tooth 10pFor its transverse tooth thickness LSTwice, that is, its transverse tooth thickness LSWith space width LeIt is equal.It is excellent

These settings can make it that the positioning of the dual-axle motor of the present invention in the circumferential is more accurate.
Referring to Fig. 7, the transversary signal of the stator core and mover core for the dual-axle motor of this preferred embodiment
Figure.In the present embodiment, two two stator poles in diameter both ends face are divided into one group., will for ease of distinguishing and describing
Eight stator poles are denoted as a and a again after packet ' (A groups), b and b ' (B groups), c and c ' (C groups), d and d ' (D groups).With group two
Stator tooth 210 in individual stator poles then synchronously with the face of mover tooth 10 and staggering, stator tooth 210 synchronously with mover tooth 10 just
Pair and then same group of different stator poles staggering.
Conductive coil 5 is wound with each stator poles, can attract and make in magnetic field caused by energization based on conductive coil
The principle that mover core move to magnetic resistance minimum position, when be powered in the conductive coil 5 in A groups, other group of no power when, it is dynamic
Sub- axle 4 can move to the minimum position of magnetic resistance under magneticaction, i.e. Fig. 3 and the position shown in Fig. 7.Wherein, stator poles a and fixed
After conductive coil 5 on sub- pole a ' is powered, its field pole encouraged opposite (i.e. magnetic in ground for circumference
The center of circle is pointed in the N poles of pole, and the N poles of another magnetic pole deviate from the center of circle), to form the less closed path of magnetic resistance.Now, A groups
Stator tooth 210 and the face of mover tooth 10, stator tooths 210 and the mover tooth 10 of other groups stagger certain angle, and fixed in B, C, D group
Angulation θ is different between corresponding mover tooth 10 for sub- tooth 210.This set may be simply referred to as the four phase ends of the earth.
Now, if being powered off to A groups, and D groups are powered, then under magneticaction, the meeting rotate counterclockwise of mover axle 4, until D
The stator tooth 210 of group and the face of mover tooth 10；Now, if being powered off to A groups, and B groups are powered, then under magneticaction, mover
Axle 4 can turn clockwise, until the stator tooth 210 of B groups and the face of mover tooth 10.Conductive coil 5 in each stator pole groups is logical
After electricity, the final position that mover axle 4 rotates can be described as a rotational positioning point.
To enable these rotational positioning point uniform fold whole circumferences, what those skilled in the art was readily appreciated that
It is that the position of other stator tooths when the stator tooth 210 of A groups is with mover 10 face of tooth, can be adjusted so that the stator tooth of other groups
210 can form an arithmetic progression with the corresponding angulation θ of mover tooth 10.For example, in the present embodiment, 50 are moved altogether
Sub- tooth 10 is angle of circumference θ corresponding to the tooth pitch of mover tooth 100For 7.2 degree, thus may be such that the stator tooth 210 of B, C, D group with
Angulation θ is respectively 1.8 degree, 3.6 degree and 5.4 degree between corresponding mover tooth 10.The tolerance of the arithmetic progression is 1.8
Degree, i.e., 7.2 degree of a quarter.
In some other embodiments, the two-phase ends of the earth is could be arranged to, such as by a, a ', b and b ' (be arranged to one group, b,
B ', d and d ' are arranged to one group.When the stator tooth 210 of a stator pole groups is with mover 10 face of tooth, another stator pole groups
The stator tooth 210 and corresponding angulation θ of mover tooth 10 is θ0Half, i.e., 3.6 degree.
In some other embodiments, so it is easy to understand that two-phase quadrupole can also be similarly set to, so when one
When the stator tooth 210 of individual stator pole groups is with mover 10 face of tooth, the stator tooth 210 of another stator pole groups and corresponding mover
The angulation θ of tooth 10 is also θ0Half.
It is easily understood that in some other embodiments, the number of mover pole can also be other numbers outside 50
Mesh.In extreme circumstances, the group number of stator poles can be reduced to two, and so, mover axle at least has two rotations in the circumferential
Anchor point, you can complete circumferential drive actions, and there is self-startup ability.Stator tooth number in each stator poles can be reduced
To two.Each stator pole groups can only include a stator poles, but preferably scheme is that each stator pole groups comprise at least two
Stator poles, tried one's best small loop with forming magnetic resistance；When each stator pole groups include and only determine including being located at two of diameter both ends
During sub- pole, each stator core one shares even number stator poles.More preferably scheme is that every group includes 2nIndividual stator poles, wherein n are
Integer more than or equal to 1, such as every group may include 2,4 or 8 stator poles etc..It is easily understood that in others one
In a little embodiments, the number for the stator poles that each stator pole groups are included can also differ, or 2nNumber in addition.
Above terminal describes driving in the circumferential.Driving principle in the axial direction is similar therewith, because will be upper
After the curvature infinitely increase for stating the circumference of rotation, you can be also considered as above-mentioned rotation circumferentially circumferentially in tangential direction
Translation.
As shown in figure 8, the stator core for the dual-axle motor of another preferred embodiment of the present invention is in certain with mover core
Position relationship schematic diagram during one relative position in the axial direction.Wherein, left and right directions corresponds to axially.The twin shaft of the embodiment
Motor is provided with five mover cores, and five stator cores 1a, 1b, 1c, 1d and 1e altogether.This five mover cores are divided into E
Group (including mover core e, e ' and e ") and F groups (including mover core f and f ').E groups are powered, mover core after F group no powers
Axial location relation with stator core is as shown in Figure 8.When the energization of E groups, F group no powers, stator core 1a, 1c and 1e production
Raw excitation field, stator core 1b and 1d do not produce excitation field.Because E groups mover core is at a distance of stator core 1a, 1c and 1e
It is closer to the distance, therefore stator core 1a, 1c and 1e mainly produce magnetic force to E groups mover core, attract E groups mover cores simultaneously
Whole mover axle and other mover cores are driven together to be moved towards the minimum position of magnetic resistance to the relative position shown in Fig. 8.Motion
When in place, each mover core of E group mover cores faces with a stator core respectively, i.e. mover core e and stator core
1a is faced, mover core e ' and stator core 1c is faced, mover core e " and stator core 1e is faced.And mover core
F and stator core 1b is staggered, mover core f ' and stator core 1d is staggered.
Now, after the power-off of E groups, F groups is powered, stator core 1a, 1c and 1e do not produce excitation field, stator core 1b
Excitation field is produced with 1d.Because F groups mover core is at a distance of the closer to the distance of stator core 1a, 1c and 1e, therefore stator core
1b and 1d mainly produces magnetic force to F groups mover core, attracts F groups mover core and drives whole mover axle and other mover cores
Together move to the relative position shown in Fig. 9 to the left towards the minimum position of magnetic resistance.Motion in place when, F group mover cores it is each
Mover core is faced with a stator core respectively, i.e. mover core f and stator core 1b is faced, mover core f ' is with determining
Son 1d unshakable in one's determination is faced.And mover core e and stator core 1a is staggered, mover core e ' and stator core 1c is staggered, moves
Son e " and stator core 1e unshakable in one's determination is staggered.
Mover core and the axial location relation of stator core are as shown in Figure 9.Left and right directions in Fig. 9 corresponds to axle
To.
Identical with the axial dipole field distance L between the mover core of group and corresponding stator core in Fig. 8, L is with just
Minus symbol." corresponding stator core " is meant, should when specified a certain mover core is corresponding with a certain stator core
The m-th stator core of phase the same side of the m-th mover core of mover core axial direction side and the stator core axial direction also phase
It is corresponding.For example, when specified mover core f is corresponding with stator core 1b, second mover of mover core f right side one end
F ' unshakable in one's determination is also F groups, and second stator core of one end be stator core 1c on the right side of stator core 1b, thus mover core f ' and
Stator core 1c is also corresponding.Here why specify mover core f corresponding with stator core 1b, be because in others one
In a little embodiments, mover core f can also be specified corresponding with stator core 1d.Correspondingly, when specified mover core f and stator
When 1d unshakable in one's determination is corresponding, mover core f ' is then corresponding with second stator core of stator core 1d rights.Stator iron in Fig. 8
Heart Limited Number, make stator core 1d rights corresponding with mover core f ' without displayable stator core.But easily it is conceivable to
It is in other embodiments, when accordingly increasing several such as stator core, then obviously can have stator core to correspond to therewith.
When conductive coil 5 in any one stator poles in any one stator core is powered, also mover axle 4 can be made to exist
Moved on axially to corresponding axially position point.The axially position point for the stator core center line and mover core center line just
To position.In extreme circumstances, the group number of stator core can reduce to three, and every group can only include a stator core.So,
Mover axle at least has three translation anchor points in the axial direction, you can completes axial drive actions.
Because motion has relativity, therefore stator core can also mutually be exchanged with the axial location of mover core, i.e.,
Mover core is set in the axial correspondence position of stator core, and stator core instead is set in the axial location of mover core, this
Sample can also reach the axially position effect of identical (being only in opposite direction).When each mover core group only includes a mover
When unshakable in one's determination, the spacing between adjacent each mover core is identical, still identical after exchange；And when each mover core group includes two
During the mover core of the above, the spacing between adjacent each mover core then can be variant, that is, is not equidistant, the phase after exchange
The spacing of adjacent stator core is also thus different.As shown in Figure 10, it is the dual-axle motor of further embodiment of the invention
Position relationship schematic diagram when stator core and mover core be in a certain relative position in the axial direction, it can be by moving in Fig. 8
Sub unshakable in one's determination and stator core obtains after exchanging relative position.
Figure 11 is the position on the mover core of dual-axle motor and the axial direction of stator core of another preferred embodiment of the present invention
Put relation schematic diagram.As illustrated, mover core has 5, respectively 1a, 1b, 1c, 1d and 1e.Stator core has 3, respectively
For A, B and C, it each forms a stator core group.Its feature in some position is：Mover core 1c and stator core
B aligns, and mover core 1b staggers with stator core A and, mover core 1d and stator core C overlapping with having on the right side of stator core A
Stagger and overlapping with having on the left of stator core C.If mover core is equal with the facewidth of stator core and is w, stator core with
At intervals of d between adjacent stator core, interval is preferably also w between mover core and adjacent mover core, then has d=m*w-w/
N, wherein m, n=1,2,3 ....
By taking Figure 11 as an example, if successively to stator core C, B, A excitation be powered (some stator core be powered when, other stators
Iron core power-off), then mover core and mover axle can move right；If conversely, successively to stator core A, C, B excitation be powered,
Mover core and mover axially move left.
