Embodiment
Below with reference to accompanying drawing, embodiment of the present utility model is described.
An aspect of the present utility model discloses a kind of permanent-magnetism linear motor and for the permanent magnet array assembly of permanent-magnetism linear motor.
Fig. 6 shows the schematic diagram according to permanent-magnetism linear motor of the present utility model.
As shown in Figure 6, according to permanent-magnetism linear motor of the present utility model, comprise armature winding (coil windings) 610 and permanent magnet array assembly.Armature winding 610 and permanent magnet array assembly are configured to can be along predetermined direction (also can be called " direction of motion ") relative motion.
According in permanent magnet array assembly of the present utility model, permanent magnet array 620,625 is fixed on mounting panel.In one embodiment, the length of permanent magnet array 620,625 in the direction of motion can be greater than the length of armature winding 610 in the direction of motion.Permanent magnet array assembly can be fixed, and armature winding 610 motions.
For ease of describing, hereinafter above-mentioned predetermined direction (direction of motion) is defined as to directions X.
The plane (array plane) of arranging permanent magnet array 620,625 can be substantially parallel with the plane (being to be also parallel to the plane of paper in Fig. 6) of crossing two line slideways 630 in Fig. 6, at this, is commonly referred to as " motor movement plane " or " array plane ".Armature winding 610 is parallel to motor movement plane and carries out relative motion.Armature winding 610 is also substantially parallel with array plane with permanent magnet surfaces opposite to each other.
Direction perpendicular to the direction of motion (directions X) in motor movement plane is defined as Y-direction.
Perpendicular to the direction of motor movement plane (being also perpendicular to the direction of paper in Fig. 6), be defined as Z direction.Armature winding 610 is positioned at above permanent magnet array 620,625 in Z direction.
Permanent magnet array comprises two groups of permanent magnets (for example magnet), and example is left bank permanent magnet array 620 and right row's permanent magnet array 625 as shown in Figure 6.
Two groups of permanent magnets 620,625 are disposed in the both sides of the straight line on above-mentioned predetermined direction (direction of motion, directions X), and are arranged to symmetrical with respect to this straight line.
In Fig. 6, this straight line can be that whole permanent magnet array 620,625 is parallel to the center line of directions X in motor movement plane.Line slideway 630 also can be arranged to symmetrical with respect to this center line.Obviously, this straight line is not necessary for above-mentioned center line.
A plurality of permanent magnets in each group permanent magnet are arranged in order along above-mentioned predetermined direction (direction of motion, directions X).
It is the situation of row that each group permanent magnet row has been shown in Fig. 6.It will be understood by those skilled in the art that a plurality of permanent magnets in one group of permanent magnet can also be as required and row is multiple row.
The surface away from mounting panel of permanent magnet is defined as to upper surface here.Usually, the upper surface of permanent magnet is parallel to above-mentioned array plane (X-Y plane, motor movement plane), perpendicular to Z direction.Armature winding is faced mutually with the upper surface of permanent magnet.
As shown in Figure 6, each permanent magnet is tilting with respect to above-mentioned predetermined direction (direction of motion, directions X).More generally, both not parallel also out of plumb of at least a portion at the adjoining edge of the adjacent permanent magnet with same group of permanent magnet of the upper surface of each permanent magnet and above-mentioned predetermined direction (direction of motion, directions X).
The upper surface of permanent magnet can be plane, can be also curved surface.The upper surface of at present conventional permanent magnet is plane.
The situation that the upper surface that permanent magnet has been shown in Fig. 6 is parallelogram.
In the embodiment that is parallelogram at upper surface, the upper surface of each permanent magnet can have longer sides and compared with minor face.In same group of permanent magnet, the longer sides of two adjacent permanent magnets is adjoining, thereby forms slit.
The longer sides of permanent magnet becomes predetermined angular with respect to Y-direction, makes both both not parallel also out of plumb.This predetermined angular can be called " oblique angle ".In an embodiment of the present utility model, oblique angle can be greater than 6 ° and be less than 40 °.More preferably, oblique angle can be greater than 8 ° and be less than 40 °.
The oblique angle of a plurality of permanent magnets in each group permanent magnet can be identical, also can be different.In Fig. 6, the oblique angle of one group of permanent magnet is identical.
In Fig. 6, illustrated two groups of permanent magnets upper surface compared with minor face, be parallel to center line (symmetry axis), and near center line adjoining situation.But this is not necessary.For example, the upper surface of permanent magnet can also be comparatively simple rectangle.Thus, when its longer sides and Y-direction have angle θ, its compared with minor face also with the directions X θ that has angle.
As those skilled in the art can understand, the upper surface of permanent magnet can also be other shape.For example, in same group of permanent magnet, the adjoining edge of two adjacent permanent magnets can comprise a plurality of line segments, and each line segment is not identical with the angle of Y-direction.Even, in same group of permanent magnet, the adjoining edge of two adjacent permanent magnets can also comprise buckling curve, for example circular arc.
Can there is conventional iron cored structure as shown in Figure 1 with the armature winding 610 being used in conjunction with according to permanent magnet array assembly of the present utility model, and can be the same with the armature winding 203 shown in Fig. 2,4, by slide block (not shown in Fig. 6), on guide rail 630, slide.Slide block rides on guide rail 630, and at least a portion of slide block is adjacent with guide rail 630 in the Y direction, so that when armature winding 610 moves along directions X with respect to permanent magnet array assembly, and the motion in the Y direction of restriction armature winding 610.In one embodiment, two slide blocks of armature winding 610 coordinate with two guide rails 630 fixing on mounting panel, to limit armature winding 610 motion in the Y direction, and armature winding 610 can be free to slide on directions X.
Fig. 7 shows the simplification force analysis figure according to the armature winding 610 in permanent-magnetism linear motor of the present utility model.
Armature winding 610, except being subject to the power on directions X, is also subject to the attraction Far that attraction Fal that left bank permanent magnet array 620 applies and right row's permanent magnet array 625 apply.Attraction Fal and Far have respectively component F aly and the Fary in Y-direction.
Because left bank permanent magnet array 620 and right row's permanent magnet array 625 are arranged symmetrically with, so the Y-direction component F aly of attraction Fal and Far and Fary big or small identical and opposite direction substantially.
So left and right two row's permanent magnet arrays 620 and 625 impose on the attraction Fal of armature winding 610 and Y-direction component F aly and the Fary of Far cancel out each other substantially, total attraction is remaining Z durection component only.When armature winding 610 moves in the direction of motion, the size and Orientation of the power from left bank permanent magnet array 620 and right row's permanent magnet array 625 that it is suffered all can change respectively, but always substantially with respect to X-Z plane symmetry.Therefore the power that left bank permanent magnet array 620 and right row's permanent magnet array 625 impose on armature winding 610 component in the Y direction is always cancelled out each other substantially, in Y-direction, always makes a concerted effort substantially zero.
Therefore, armature winding 610 is not subject to the power that permanent magnet array applies in the Y direction substantially.
Like this, by when making that permanent magnet is tilting and reduce teeth groove power, offset the cross component force (Y-direction component) producing because permanent magnet is tilting.
By offsetting Y-direction component (tilting teeth groove power), reduced armature winding 610 play in the Y direction under the impact of Y-direction component, effectively improved the running precision of motor, can avoid the tilting teeth groove power changing in diverse location along with armature winding 610 in motor operation course to affect the fatigue life of line slideway and the reliability of motor simultaneously.
Except above-mentioned beneficial effect, the above-mentioned permanent-magnetism linear motor of the utility model also has at least following advantage with respect to traditional permanent-magnetism linear motor shown in Fig. 2.
1. oblique angle can be larger
Large oblique angle is favourable to reducing teeth groove power.
Yet, in traditional permanent-magnetism linear motor shown in Fig. 2, though single tilting permanent magnet can reduce teeth groove power, can bring the adverse effect of tilting component.Oblique angle is larger, and tilting teeth groove power is also larger.Owing to there being this unfavorable factor, oblique angle can not be too large.In tradition permanent-magnetism linear motor, oblique angle θ is generally between 0 °～6 °.
Shown in Fig. 6, according to permanent-magnetism linear motor of the present utility model, adopt symmetrical structure to balance out the adverse effect of tilting component, thereby can adopt larger oblique angle, make like this design of electrical motor person have and select more flexibly space.As mentioned above, in permanent-magnetism linear motor of the present utility model, oblique angle θ can be arranged between 6 °～40 °, even can arrange as required greatlyr.Thereby reduce to a greater extent teeth groove power.
2. permanent magnet effective length can be longer
As shown in Figure 5, after permanent magnet is tilting, the effective length of permanent magnet reduces, thereby reduces the power output of motor.For the permanent magnet of same length, oblique angle is larger, and motor power output is less.In traditional permanent-magnetism linear motor as shown in Figure 2, when selecting longer permanent magnet when realizing longer effective length, the also corresponding increase of tilting teeth groove power.
Permanent-magnetism linear motor of the present utility model shown in Fig. 6 adopts two symmetrical tilting row's permanent magnets, and the impact of the tilting teeth groove power that no longer needs to worry, therefore can select the permanent magnet of more growing.
In addition, in fact, permanent magnet (particularly magnet) itself is difficult to do length, processes and magnetizes all very difficult.Use two symmetrical tilting row's permanent magnets also can lengthen comparatively easily the effective length of the permanent magnet that synchronization works to armature winding 610.
Along with the increase of permanent magnet effective length, can increase the motive force to armature winding 610 outputs.
3. larger drive current
Not by the tilting motor of permanent magnet because teeth groove power is large, the interference of motor operation is just large, the precision of moving is like this influenced, and drive current is larger, affects greatlyr, can not adopt very big current drives, has limited the output of actuating force.
In traditional permanent-magnetism linear motor as shown in Figure 2, although can reduce to a certain extent teeth groove power, introduced tilting teeth groove power.And similarly, drive current is larger, the impact of tilting teeth groove power is also larger.Therefore can not adopt very big current drives equally, limit the output of actuating force.
And in permanent-magnetism linear motor of the present utility model shown in Fig. 6, because the disturbance of teeth groove power has reduced, tilting teeth groove power has also been eliminated, motor can be worked under larger drive current, obtain larger power output, can offset the permanent magnet effective length of bringing because permanent magnet is tilting completely and reduce the impact on motor power output.
Experiment shows, by using the tilting permanent magnet array of double symmetry, drive current can be multiplied, and motor still can steadily accurately move.The maximum drive current of traditional permanent-magnetism linear motor shown in Fig. 2 is generally less than 30A.And the maximum drive current of the permanent-magnetism linear motor of the tilting permanent magnet array of the double symmetry of use of the present utility model can be up to 50～80A.
In a word, the utility model is used the motor of the tilting permanent magnet array of double symmetry not only can obtain less teeth groove power, higher kinematic accuracy and less motor fluctuation, and can be by applying larger drive current to the larger actuating force of armature winding 601 output.The actuating force that the model machine of design produces under the drive current of 30A according to the method can surpass 2000N, and teeth groove power is less than 20N.After being further optimized, actuating force can also further improve, and teeth groove power also can further reduce.
According to another aspect of the present utility model, also provide a kind of rotary permanent-magnet motor and for the magneto parts of rotary permanent-magnet motor.
As those skilled in the known, permanent-magnetism linear motor can be considered as rotary permanent-magnet motor to launch visually, and that rotary permanent-magnet motor can be considered as permanent-magnetism linear motor to be rolled into is visually cylindric.
Therefore, based on the utility model permanent-magnetism linear motor as shown in Figure 6, those skilled in the art easily expect, inventive concept of the present utility model can also be for rotary permanent-magnet motor and parts thereof.These parts are configured to can be as stator or the rotor of this magneto.
On these magneto parts, be furnished with permanent magnet array, these magneto parts have axially, and each some place has the center of circle of sensing radially on its circumference.
Similarly, this permanent magnet array also comprises two groups of permanent magnets.
These two groups of permanent magnets are arranged in both sides, a sagittal plane perpendicular to axial direction, and symmetrical with respect to this sagittal plane.
A plurality of permanent magnets in each group permanent magnet are arranged in order along the circumference of these magneto parts.Generally speaking, a plurality of permanent magnets become a circle around the circumferential arrangement of these magneto parts.
The outer surface of each permanent magnet is substantially perpendicular on its place circumference and a bit locates radially.Here said outer surface refers to the surface away from this magneto hardware body.
At least a portion at the edge that the adjacent permanent magnet with same group of permanent magnet of the outer surface of each permanent magnet is adjoining was with axially both out of plumb was also not parallel.
The shape of the outer surface of permanent magnet can be identical with the permanent magnet of the previously described permanent magnet array assembly for permanent-magnetism linear motor.
In one embodiment, the upper surface of permanent magnet is parallelogram.This parallelogram can have longer sides and compared with minor face, in longer sides and same group of permanent magnet, the longer sides of the upper surface of adjacent permanent magnet is adjoining.Therefore, longer sides was with axially both out of plumb was also not parallel.
