First Line coil assembly and the second coil block are set to substantially symmetrical with respect to central plane, and are fixed together by connector.
The in the situation that of permanent magnet linear motor, the first magnet assemblies and the second magnet assemblies definition direction of motion, the direction that a plurality of magnet is arranged in order.Central plane is parallel to the direction of motion.
The in the situation that of rotary permanent-magnet motor, this magneto comprises rotor and stator.The first magnet assemblies and the second magnet assemblies are arranged in rotor and stator.First Line coil assembly and the second coil block are arranged on another in rotor and stator.Central plane is perpendicular to axial (being parallel to direction of rotation) of stator and rotor.
Like this, due to the first motor and the second motor with respect to be parallel to the direction of motion (or, the in the situation that of rotary permanent-magnet motor, perpendicular to axial direction) central plane be symmetrical arranged, the power perpendicular to the direction of motion (being parallel to axially) that First Line coil assembly and the second coil block are subject to is opposite direction each other, equal and opposite in direction.And owing to connector, First Line coil assembly and the second coil block being fixed together, so the power that First Line coil assembly and the second coil block are subject on perpendicular to central plane direction respectively cancels each other out.Like this, eliminate at least in part the cross force perpendicular to the direction of motion, contributed to promote the performance of magneto.

In the magneto shown in Fig. 3, within being parallel to the surperficial plane that magnet assemblies faces mutually with coil block, direction (Y-direction) perpendicular to the direction of motion (directions X) is upper, First Line coil assembly 320 and the suffered power equal and opposite in direction of the second coil block 325, opposite direction.In the situation that using connector 330 that First Line coil assembly 320 is fixedly connected with the second coil block 325, power suffered in Y-direction is all cancelled substantially.
For example, when in order to reduce teeth groove power by the situation of the magnet slant setting in magnet assemblies (having angle with respect to the direction of motion (directions X)), by symmetry, place two groups of magnet assemblies, and two coil blocks of relative set, can eliminate the tilting teeth groove power in produced Y-direction.
The second embodiment
Fig. 4 is according to the schematic configuration diagram of the permanent magnet linear motor of second embodiment of the invention.
According to the permanent magnet linear motor of the second embodiment, comprise the first magnet assemblies (magnet array) 410 being arranged on the first magnet mounting panel 411 and be arranged on the second magnet assemblies (magnet array) 415 on the second magnet mounting panel 417; The First Line coil assembly 420 and the second coil block 425 that are oppositely arranged with the first magnet assemblies 410 and the second magnet assemblies 415 respectively; Be fixedly connected with the connector (workpiece) 430 of First Line coil assembly 420 and the second coil block 425; And guide rail 450 and slide block 460, connector 430 slides on guide rail 450 by slide block 460.

By being symmetrical arranged as shown in Figure 4 two magnet assemblies and two coil blocks, can offset equally perpendicular to the part power in the direction of the direction of motion.
The 3rd embodiment
Fig. 5 is according to the schematic configuration diagram of the permanent magnet linear motor of third embodiment of the invention.Fig. 6 is the schematic diagram along the direction of motion according to the permanent magnet linear motor of third embodiment of the invention.
According to the permanent magnet linear motor of the 3rd embodiment, comprise the first magnet assemblies (magnet array) 510 and the second magnet assemblies (magnet array) 515 on the two opposite sides that is arranged on magnet mounting panel 518; The First Line coil assembly 520 and the second coil block 525 that are oppositely arranged with the first magnet assemblies 510 and the second magnet assemblies 515 respectively; Be fixedly connected with the connector (workpiece) 530 of First Line coil assembly 520 and the second coil block 525; Guide rail 550 and slide block 560, connector 530 slides on guide rail 550 by slide block 560; And linear displacement transducer 540.
The first magnet assemblies 510 and the second magnet assemblies 515 (and magnet mounting panel 518) have defined substantially the direction of motion along directions X.
Central plane between the first magnet assemblies 510 and the second magnet assemblies 515 is parallel to X-Z plane.Y-direction is vertical with central plane.Z direction is all vertical with directions X, Y-direction.
The attraction that First Line coil assembly 520 is subject to the first magnet assemblies 510 is in-Y-direction.The attraction that the second coil block 525 is subject to the second magnet assemblies 515 in the Y direction.The attraction size that two coil blocks are subject to is respectively substantially equal, and direction is substantially contrary.Like this, these two suffered attractions of coil block are cancelled.
In traditional iron core permanent magnet linear motor, because the coil of iron core linear electric motors is (as shown in Figure 2) that are embedded in iron core, iron core is made by the good material of magnetic property, is just existing normal direction attraction (referring to Fig. 1) very large in Z direction like this between core-coil assembly and magnet assemblies.Conventionally the several times that this normal direction attraction is motor power output, sometimes even up to more than ten times.Like this, the linear bearing of connector (workpiece) and motor is just bearing very large normal force, and this is unfavorable factor to machine operation, and especially workpiece just must have reasonable Rigidity and strength, and the quality of workpiece is just difficult to further reduce.The quality of certainly wishing workpiece in motor platform work is the smaller the better, is conducive to like this improve the actual driving force of motor.Therefore, in the prior art, the fan-out capability that further improves motor platform how in limited space in (especially motor platform Width size is limited, and both Y-direction size was limited) is puzzlement design of electrical motor person's a difficult problem.
According to the permanent magnet linear motor of third embodiment of the invention, solved well this problem as shown in Figure 5.
Employing is according to the new structure of third embodiment of the invention, and the motor of dexterously level being installed converts vertical installation to, is originally that the normal direction attraction of Z direction just converts the power in Y-direction to.Be conducive to like this improve the stressing conditions of workpiece, the larger normal force that original workpiece is born has eliminated, and is beneficial to the optimal design of workpiece, can alleviate distortion and the quality of workpiece, is beneficial to and improves motor power output and precision.
Simultaneously, originally very large normal direction attraction has been eliminated, the linear bearing of platform (guide rail) stressing conditions also will obtain larger improvement, can improve kinematic accuracy and the life-span of bearing, linear bearing that even can selection of small is realized original designing requirement, so not only save cost but also further improved the fan-out capability (quality of general less its moving slide block of linear bearing is also less, and motor can promote the pay(useful) load of larger quality like this) of motor.
According to the permanent magnet linear motor of third embodiment of the invention, it is a kind of difference structure.As long as can guarantee that in the assembling process of platform two spacing between coil block keep stable or basicly stable in motor operation course, in motor movement process, motor gas-gap δ 1 and motor gas-gap δ 2 need not remain unchanged or be stable so, also needn't require these two air gaps equal or substantially equal in motor operation course.That is to say that motor gas-gap has not been sensitive parameter at this, as shown in Figure 6 as long as keep the spacing between two coil blocks constant.These are completely different from the flat iron core linear electric motors shown in Fig. 1, motor gas-gap in the structure of Fig. 1 (both spacing of the normal direction Z direction of coil block and magnet assemblies) is a highstrung parameter, if air gap changes greatly in motor operation course, can affect significantly the runnability of motor so, even cause motor cisco unity malfunction.We know that the spacing d guaranteeing between two coil blocks keeps stable or basicly stable mechanically than being easier to realization in motor operation course, and to guarantee in motor movement process air gap constant be more difficult, and machine cost is also larger.According to the permanent magnet linear motor of third embodiment of the invention, can reduce greatly matching requirements and the precision of magnet assemblies, greatly reduce machining and the installation cost of platform.
