The present invention relates to a linear motor, a motor, a linear motor stator iron core, and a [prior art] a —general 'electric motor and soft magnetic component of an electric machine, also known as iron core = using a soft magnetic material such as iron or iron Fabrication of Insulation Sheets of Yan Steel. The soft magnetic phase insulation thin sheet can still be called Jizhanyou "", and "A" plate. The iron core is made of laminated plates, which is to reduce the efficiency of electric motors and electric machines in order to reduce the eddy current. In a linear motor with a ring-shaped stator core and a tubular mover, the mover is a part of the linear motor, and it must be pushed by a fork by interacting with the stator magnetic field. Each thin metal sheet system is arranged radially and On the axial plane, the effect of thirst current is minimized. # In some linear motor towels, the thin metal sheets are stacked in parallel to form an iron β part. The iron core part is arranged so that the metal sheet It lies on the radial axial plane, so that other thin metal sheets are parallel to the one thin metal sheet. The problem with the stator core made as described above is that the coil must be wound into a slot of the stator core. This winding work is particularly troublesome when the slot openings are arranged on the inner peripheral surface of the stator core. In addition, the linear motor using the above technology is based on the ratio of the generated force to the total space volume of the linear motor (i.e. Produce In terms of strength / space volume), they are inefficient. For this reason, a linear motor is urgently needed, which generates a specific force with a small space body ^ 1787.d〇c -6- 200425617. Although a kind of stator is needed, it is easier to install a coil. Wu Guo Patent No. 6,060,810 proposes a stator for a linear motor, which has a laminated core of a wrong core. The stator includes a stator wound in a cylindrical shape. The coil and the L-shaped laminated sheet; the latter has a horizontal unit and a vertical unit. The horizontal unit containing most of the laminated sheets is staggered into a radiating shape on the upper and lower surfaces, and if so, forming a cylinder Shape. When constructing this stator, there is no need to wind the coil through the stator slot. However, it is quite cumbersome to build the stator core to the coil. In addition, according to US Patent No. 6,060,81 The stator core is still not effective when the ratio of the generated force to the space capacity of the motor is taken into account. [Summary of the Invention] An object of the present invention is to provide a device for improving a linear motor. , By means of a stator core according to the scope of the patent application, the mover of item 9, the linear motor of item 16, and the stator core of item 18. A preferred embodiment of the present invention is disclosed. Within the scope of each dependent patent application. In particular, according to one aspect of the invention, a stator core for a linear motor includes an inner periphery; a substantially surrounding outer periphery of the inner periphery; Two teeth are arranged along one of the inner periphery or the outer periphery, a slot for receiving a certain sub-coil, the slot is a cavity arranged in the stator core; wherein the stator core is It is divided into a first stator component and a second stator component; the 定子 -stator component includes, is arranged partly as a boundary of the slot, and is made of soft magnetic powder; and the second stator part 91787 doc 200425617 includes the first The two teeth are arranged partly as the boundary of the slot, and are made of soft magnetic powder. The stator core is divided into two stator parts, each containing one tooth, and the coil is placed in the female core of the iron core, which is convenient because the coil can be easily placed when the two stator elements are separated. In the first part of the two stator parts, the second part can then be easily placed in close contact with the first stator part to form a stator or a 疋 子 段 筇. This embodiment can allow the use of pre-wound, = turns, which can be easily placed in the stator core when the stator core is divided according to the provisions of the patented invention of this application. Therefore, the stator system 4 is facilitated. In addition, by making a soft magnetic powder stator component, the stator component can be easily manufactured even if it has to be made into a complex shape, and the stator component can still be made robustly. In addition, if necessary, the two soft magnetic powder stator parts are easy to make with high precision and mechanical protection. Therefore, the use and division of the aforementioned soft magnetic powder is divided into two separate pieces: π pieces, which can facilitate the combination of the stator. If each of the two stator components is a main body of a magnetic coil, the combination of the stators can further advance and obtain convenience. Another benefit of making soft magnetic powder stator components is that the ratio of the power generated by the stator to the total space volume of the motor can be the filling factor of the stator in particular, which can be improved. The filling factor and the ratio of the space volume of the active material to the total space volume are as follows: Iron: ‘: 提 = :::: 导: ^^ Α Aν magnetic. This relatively high magnetic permeability provides the edge edge for contacting and setting the edge of the two parts to make the two parts with high accuracy. The laminated stator core can only be supplied and magnetically permeable in the laminated 91787 doc 200425617 genus / special rice, and when the laminated plate is arranged in an axial • y-direction plane to form an outer periphery and an inner periphery In the main body, there will be no space for soft magnetic materials in Daxia. The space is often filled with low permeability H gas or some filling materials. However, by making a soft magnetic powder stator core, the magnetic flux is not limited to a "magnetic flux channel" with a constant width, and σ is more free /; IL movement (for a laminate, the width is equivalent to the thickness of each laminated sheet) . The reason is that the total volume of the stator that can be used to transmit magnetic flux is larger, and therefore, the attainable fill factor is higher, that is, the stator—and therefore the motor can be made smaller. According to a specific embodiment of the stator, the first tooth extends axially toward the first stator component by a distance, the distance varies along one of an inner periphery or an outer periphery of the stator core; and the first The two stator components extend a distance in the axial direction toward the first stator component, and the distance varies along one of the inner periphery or the outer periphery of the stator core. By varying the positions of the teeth of each stator component along the periphery in the axial direction, the variation in distance introduced can achieve a skew similar to that of a rotary motor. Therefore, in a linear motor provided with such a stator design, the occurrence of force rippie can be reduced. The two teeth can be arranged on the outer or inner periphery of the stator, depending on whether a predetermined stator is arranged outside the stator (ie, on the outer periphery of the stator) or on the inside of the stator (ie, on the inner periphery of the stator). . In a specific embodiment, the first tooth and the second tooth system are arranged in a bifurcated contact with each other. The radial extension of the two teeth that are in close contact, and the contact area between the two teeth is so small that it becomes magnetically saturated during operation. 91787.doc -9- 200425617 By setting the two teeth in contact with each other, the combination of the two stator components can be more stable, and by saturating the contact area during operation, the magnetic leakage through the contact area can be maintained On the low side. According to another specific embodiment, each of the first sub-component and the second stator component of Yanxuan includes at least two soft magnetic powder sections, and the two sections are arranged in a direction corresponding to the inner and outer periphery, so that Next to each other. This-specific embodiment can be beneficial to the production of large stators. According to a specific embodiment, the density of each of the stator components is at least 6500 kg / m3. This can cause the stator component to have good magnetic characteristics at the same time, because the soft magnetic powder makes it easy to form. In particular, the magnetic flux path need not be a two-dimensional one, as in the case of a layered iron core. According to yet another specific embodiment, the resistivity in each of the stator components is at least 1 μΩιη (micro-ohm · meter). As a result, the negative effects caused by full current can be reduced. In a specific embodiment, each of the first stator component and the second stator component is arranged to be in close contact with each other on the outer periphery and separated from each other on the inner periphery; the inner periphery is separated from each other, resulting in the first A slot opening is created between the second tooth and the second tooth, and the slot opens into the slot. In such a specific embodiment, the placement of each coil can be facilitated. In an alternative embodiment, each of the first and second stator components is configured to be in close contact with each other on the inner periphery and separated from each other on the outer periphery; the separation from each other on the outer periphery results in between the first and second teeth. A slot opening is created and passes into the slot. According to another aspect of the present invention, a mover for a linear motor includes at least 9l787.doc -10- 200425617 == segment and at least-permanent one at least, material segment line; the heart is: mover ..., into-evening The magnetization vector of the Mizuhisa magnet is axially oriented. In the related text of the son, the axial direction is either the mover or the stator, and the direction of movement depends on which of them moves relative to the other. By arranging the at least one permanent magnet having an axially oriented magnetization vector 'with the vector of at least one segment of soft magnetic material, a solid mover can be achieved. In addition, a permanent magnet that can be used in such a mover can be manufactured conveniently, because the ratio of the axial length of the permanent magnet to the width of the permanent magnet is more than that of a normal magnet used in a mover. It is too small. In a specific embodiment, the soft magnetic segment of the main body is made of soft magnetic powder. In this way, the manufacturing of the soft magnetic segment can be facilitated, and the filling factor of the mover can be improved. In another specific embodiment, the 'mover includes at least two permanent magnets: a first permanent magnet and a second permanent magnet, both of which are arranged in the axial direction, and which is located between the axial centers of the at least two permanent magnets. The distance is the pitch of 0.75-i 5 Ίσ to a common stator. Such a move in hunting design makes the pot more efficient. According to a further specific embodiment, the mover is a tubular member. According to yet another specific embodiment, the at least one segment of soft magnetic material is provided with at least a first axial end having an end surface, and wherein the at least one permanent magnet is arranged in a row substantially in line with the first axial direction. The entire end surface of the end is in contact. According to this specific embodiment, 'the contact surface between the at least one soft magnetic material section 9l787.doc -11-200425617 and the at least one 17th day of the Buddha, the long magnet is large, and therefore the mover may Become more effective. In a specific embodiment, the at least—of the permanent magnets—is arranged on the circumference and the axis = zhang = surface ', and is substantially the same as one of the one of the movers. The surface is expanded in the circumference and the secret direction. An established stator. According to another aspect of the present invention, the first-line 11 motor includes a fixed iron core according to any of the foregoing specific embodiments of the stator core. Such a linear motor may therefore have the same disadvantages as that of the specific embodiment in which the carrier is centered. According to another embodiment of the linear motor, the linear motor further includes a mover according to any one of the foregoing specific embodiments of the mover. Such a linear motor ' may therefore have the same benefits as that particular embodiment of the mover. : According to yet another aspect of the present invention, a stator iron for a linear motor includes a stator core, wherein the ring is divided into at least two ring-shaped stator parts, a first stator part and a second stator. Qiu Du Pinganshi-focus on the pieces, and the two stator parts are homogeneous bodies made of soft magnetic powder.

A schematic view of a linear motor according to the invention is presented in Figs. Zhanhai linear motor 10 includes-fixed;. ^ T dagger 12 and a mover 14. Usually, the stator drives the mover in the axial direction without moving. However, it is also possible to keep the mover stationary and drive itself in the axial direction. Therefore, the material phase — 'refers to the direction of movement of the mover or stator (depending on which of the two moves relative to one of them).

Make & outer south pole ㈣, And the magnetic tube 28d with its south pole facing outward from north to inward. The magnetic tubes 28a-d can be any means 26 known to those skilled in the art. The axial length of the mover can be different from that shown in FIG. 4 The length of the magnetic tube may be different. The axial length of the magnetic tube 28 "and the number of the magnetic tube may be changed, depending on where the linear motor 10 is used. According to a solid embodiment, the axial length Lm of each of the magnetic tubes 28 may be a pitch LAG · 75 between the centers of the two consecutive teeth of the m]. 5 times, that is, the relationship Lm / Lp may be 0.75 -L5. For this application, the pitch can be clearly seen as the distance between the centerlines of the two adjacent teeth. In Figures 2a-b, a specific embodiment of another linear motor is shown. This embodiment Similar to the embodiment of Figs. La-c, the differences therebetween will be described below. The stator 12 of the linear motor 10 includes an additional component: an inner stator component 30. The inner stator component 30 may be provided in the The stator members 21 & and 22a-c are internal parts, and a space is left between the outer periphery of the inner stator member 30 and the inner periphery of the stator members 21a-c and 22a-c. The inner stator member The function lies in playing a role in the magnetic circuit; each of the stator components 2la-c & 22a-c also plays a role in the magnetic circuit. The inner stator component] ^, as the rest of the stator described in the month Parts, made using the same soft magnetic material and the same technology. The inner stator component is configured to maintain its relevance to the specifications The positions of parts 21a-c and 22a_c. 9l787.doc -16- 200425617 In addition, this mover is different from the mover in Fig. La < The mover in the embodiment in Fig. 2a uses only magnetic tubes 28a-d These magnetic tubes are permanent magnets, an embodiment as shown in Figures la-c, and they can be configured with their polarization vectors pointing to the poles corresponding to the permanent magnets shown in Figure la-c. In this way, the mover can be made lighter than the mover in Fig. La_c, however, it is also a cause and effect, the mover becomes more fragile, especially where the two magnetic * 28a_d are connected. Provincial relationship Lm / Lp It may have the same relationship as the embodiment shown in Fig. 1 ac. In Figs. 3a-b, another specific embodiment of a linear motor is shown. This κ% example is also similar to the embodiment of Fig. 1 ac, in the meantime The difference will be described below. The stator 12 may be identical to the stator of Figs. La-c. However, the mover 14 may be a soft magnetic tube 32a-d, where the soft magnetic tube 32a-di is broken by a permanent magnet Replaced by ring 34a-c. The permanent magnet ring series is placed in a soft magnetic tube so that the polarization vector of the permanent magnet is axially oriented. About this type A detailed description of the type mover will be presented below. In the specific embodiments of FIGS. 1a-c, 2a-b, and 3a-b, a stator having three stator cores and three coils has been described. However, the stator iron The number of cores and coils can be increased or decreased. The stators in Figures la-c, for example, can be expanded by an additional stator core and a corresponding stator coil. In addition, borrowing from Figures ^ 乂, 2a_b, and 3a-b In this linear motor, the stator core 20 core and the corresponding stator coil are removed, and the number of the stator cores can be reduced. In Fig. 4a-b, 'shown-has-a stator coil and a-stator core linear motor' . The mover in the figure is equivalent to the linear motor mover 'shown in Figs. 3a-b, which will be explained in more detail below. However, the mover may be any type of mover, for example, one of the movers shown in Figs. La-c and 2a-b. A stator core 20 according to a specific embodiment is shown in FIGS. 5 and 6. As mentioned on the surface, the stator core 20 is divided into two discrete stator parts: a first sub-chassis.卩 件 21 and a second stator member 22. The stator core 20 has an inner periphery 50, an outer periphery 52, and a split plane 54. The inner periphery should be understood as a straight line defining the inner limit of the stator core 20, and the outer periphery should be understood as a straight line defining the outer limit of the stator core 20. The core of the Haihezi can also be described as having a ring shape. In the figure, the outer periphery 52 surrounds the inner periphery 50, however, the stator core 20 may include a gap extending radially through the ladle core 20, yet it is still considered to have an outer periphery surrounding an inner periphery , At least substantially surrounding an inner periphery. The split plane 54 is a plane 'which results from dividing the stator core into two stator parts 21,22. In addition, the stator core 20 includes at least two teeth: a first tooth 56 and a second tooth 58; and a back iron core 60. The two teeth 56 and 58 are disposed along the inner periphery 50 to guide the magnetic flux toward and away from the vicinity of the mover. The back iron core 60 is disposed along the outer periphery 52 and is provided between the first teeth 56 and the second teeth 58 to provide a high magnetic permeability path. In the specific embodiment shown in Figs. 5 and 6, each of the stator components 21 and 22 includes a tooth 56, 58 and a part of the back iron core 60 0 and a slot 62 formed in a cavity shape and disposed in the stator iron core 2. The inner side is used to receive the stator coil. The slot is thus disposed between the outer periphery 52 and the inner periphery 50, and is partially defined by the first stator member 21 and the second stator member 22. Therefore, the slot 62 also has a circular shape. The two teeth 56 and 58 of the stator core 20 are opposite to each other in the axial direction, and a slot opening 64 is left in the middle of the two 91787 doc -18-200425617. The slot opening 64 is inserted into the slot 62 in the stator core 20. The sub-components 21 and 22, and thus the stator core, can be made of a soft magnetic material having the characteristics mentioned in the above correlation diagrams la-c. The split plane 54 of the stator core 20 may be arranged on the first surface 66 (which faces the axial direction) of the stator core and the second surface 68 (which faces the opposite axial direction) of the stator core. Towards the distance. If the two teeth 56 and 58 extend axially along the inner periphery by an equal axial distance, and the split plane 54 is arranged so that the two stator components are identical, the manufacturing of the two components requires only one set of tools. Therefore, the initial cost of producing stators can obviously be reduced compared to the need for producing two stators with two different sets of tools for producing two different stator parts 21 and 22. However, the split plane 54 may be arranged differently from that shown in Figs. Several other ways of splitting the stator core 20 into the first stator component 21 and the second stator component 22 are shown in Figs. 7a-c. These drawings are not intended to provide a complete description of the various feasible variants' of splitting the stator core. The reason why the stator core 20 is divided into at least two stator parts 21 and 22 is to facilitate the operation of arranging a coil in the stator core 20 slot 62. By splitting the stator core 20 as described above, a pre-wound coil can be used, and it can be easily put into a certain sub-component 2 1 or 22 to produce a stator containing a coil placed in its slot. The core 'then completes the stator by making another stator component 21 or 22 and the previous stator component 21 or 22 into close contact. Two specific embodiments are presented in Figs. 8-9, wherein the stator components 21 and 22 are divided into sections 74a-b, 75a-b, 76a-d, and 77a-d, corresponding to the inner and outer perimeters. Adjacent to the direction. This division, at least 9l787.doc -19- 200425617, has several benefits when making large stators. Figure post-stator core 20 Another specific embodiment. This embodiment can be based on any of the stator core embodiments described previously. In this embodiment, the axial length of each of the stator teeth 56 and 58 along the inner peripheral surface 50 may be changed. In the figure A, when the circumferential length of the inner circumference of the two teeth 56 and 58 is discussed, the axial length of the two teeth =, 58 is changed from the long length to the length ′, and then to Lmax. Its variation may be linear. The slot opening can be expanded by the same axial distance regardless of its position along the periphery 70. This can be achieved by the following arrangement of the two stator parts: the axial ㈣ length of the teeth of a sub-component is Lmax , And the other — # of the axial expansion length, are located at the same position on the periphery. The introduction of this two-tooth variable axial length is very similar to the skew introduced in rotary motors. Skew, when the associated rotary motor is used, it refers to the deviation of a slot from the axial direction by a thunder bar. The angle of the electrical angle is "twist". In most cases, 'skew is the character of the rotor—see M.asay " Alternation Current Machines ", 5th ed., Longman Scientific & Technical, 1983, (ISBN 0-582-98875-6), page 106 〇, by introducing the variable axial length of the two teeth 56 and 58, the power fluctuation of the linear motor can be reduced. / FIG. 11 shows another specific embodiment of the stator core 20. This embodiment can be based on any of the stator core embodiments described previously. In this embodiment, the axial lengths of the two and 58 are expanded to bring the two teeth into contact with each other. Expansion. The P-knife is upward, and it is narrow compared to the rest of the two teeth. The protrusion 72 must be narrowed in the radial direction to saturate the magnetic flux of the bulge 72 ′, so that a small amount of leakage magnetic flux passes through the protrusion 72. In addition, the protrusion 72 can be widened in the radial direction so that the protrusion can be used as an auxiliary support when the two stator portions 21 and 22 are arranged closely connected to each other. To make a linear motor with a single stator coil, such as those shown in Figures 4a-b, any of the aforementioned stator cores can be used. To make a linear motor with a large number of stator coils, such as those shown in Figures la-c, 2a_b, and 3a-b, the majority of the stator cores can be placed next to each other. In such a stator, that is, a stator in which stator cores are arranged adjacent to each other, and two adjacent teeth of two adjacent stator cores, from the perspective of magnetic flux, the same single tooth can be seen. If so, the center of this "magnetic" tooth must be used when determining the pitch of such a stator. In this type of 5 and 50, the magnetic teeth containing soft magnetic materials from two different stator iron cores can be called a full tooth, and the magnetic teeth at each end of the stator only include the magnetic teeth from a certain stator core Those with soft magnetic materials can be called half teeth.

The middle part 80 defines the shape of a first dense contact. If so, the 91787 doc -21-200425617 sub-slot 86 and a portion define a certain sub-slot 88. This intermediate member 80 can still be used to make a stator 12 containing more than two majority stator coils. A mover 14 is shown in Figs. 13a-c, which corresponds to a specific embodiment of the linear motor mover shown in Figs. 3a-b. The mover may include soft magnetic section sections 32a-d and permanent magnet section sections 3a-c of soft magnetic materials (ie, one of the materials stated in FIG. 1). The permanent magnet segments 34a-c can, in essence, extend from the inner periphery 102 of the mover µ to the outer periphery 104 and continuously extend along the circumference of the mover 14. To transmit magnetic flux to the soft magnetic segment segments 32a-d, the permanent magnet segment segments can be placed in close contact with the soft magnetic segment segments 32a-d. The permanent magnet segment extends beyond the surface of the mover toward the stator. Moreover, it does not need to be flush with the surface of the stator, but the permanent magnet can be shorter than the soft magnetic segments 32a-d in the axial direction until it reaches the surface. The hydromagnet segments 34a-c are arranged so that their s poles face the axial direction. In addition, the permanent magnet segment sections 34a-c are configured such that the north pole N of a permanent magnet segment section (such as 34b) faces an adjacent permanent magnet section section (such as the north pole N of 34 hooks). Therefore, the south pole of a permanent magnet section section 3 is facing the south pole S (such as 34a and 34b) adjacent to the permanent magnet. In this way, the soft magnetic segment 32a_d can function as a magnet with a radially directed polarization vector. In addition, the permanent magnet can be made in the axial direction Shorter, that is, the ratio of the axial length to the radial length of the magnet (from the inner surface to the outer surface of the mover), La / Lr 'can be smaller than that of the permanent magnet of the mover in Figs. Ia_c and 2a_b Corresponding ratio. Therefore, the manufacture of the permanent magnet can be facilitated because it is easier to make a permanent magnet with a smaller La / Lr ratio. When the mover is designed as such, it can still be stronger. 9l787.doc -22-200425617, and the mover can also be a pipe, which is provided with a groove to hold the, and in such a specific embodiment, the groove can be set so that it faces , 疋 子, and placed in the slot and away from the stator towards the magnet Part, therefore, is the material facing the pipe. Other features of such a mover are consistent with the features of other embodiments of the mover. According to a specific embodiment, the linear motor mover may include at least one 、 才 料 # Another section and at least one permanent magnet, the at least one section of soft magnetic material and 4 to J permanent magnets are arranged in the axial direction of the mover, wherein a polarization vector of the at least one permanent magnet is axial In addition, the mover segment made of soft magnetic material above can be made of soft magnetic powder. According to another specific embodiment, the mover may include at least two permanent magnets: a long-lasting magnet and a second permanent magnet; both are It is arranged in the axial direction, and the distance between the axial centers of the at least two permanent magnets is 0.75-1.5 times the pitch of a common stator. Except for the specific implementation, the permanent magnets can be arranged into No other permanent magnet is closer to the first permanent magnet than the second permanent magnet. According to yet another specific embodiment, the mover may be a tubular member. According to yet another specific embodiment, the at least The soft magnetic material section is provided with at least one first axial end having an end surface, and the at least one permanent magnet, on the bemp, is arranged to contact all the end surfaces of the first axial end. In another specific embodiment, the surface of one of the at least one permanent magnet extending in the circumference and axial direction is, in essence, connected with one of the movers configured to face a given stator 9l787.doc -23-200425617 on the circumference and The axially-extending surface is arranged flush. According to a specific embodiment, a Lo -k rb /, as described in any of the specific embodiments herein, a linear motor may include _ 如 浩 ^ The mover in a specific embodiment of the mover. The radial sections of the stator 12 and the mover 14 need not be circular. In some applications, a radial profile of another shape may be more desirable. A triangular stator core 20 is shown in FIG. 14 and includes two stator parts 21 and 22. The stator core can also be described as a ring with a triangular shape. The stator core 20 may be manufactured and / or placed in the same manner as any of the aforementioned stators. The stranded wire ® ′ to be placed on the stator iron can be a pre-wound coil regardless of the radial cross-sectional shape. A mover in a linear motor equipped with a triangular stator core may be made to have this triangular shape for best performance. The radial cross-sectional shape of the stator and / or the mover can be any shape. For example, they can be ellipses, rectangles, stars, shapes with two circles connected (that is, the shape like the number 8), etc. 'The possibilities are infinite. The deformed or usually difficult-to-form stator or mover 'or the stator and mover can be made by using soft magnetic powder or a moldable material with at least good magnetic flux permeability and current resistance as described above. The facts and convenience. 15a-b show another specific embodiment of a linear motor. This specific embodiment of the linear motor ' includes a stator 112 and a mover 114, which are similar to the linear horses described in Figs. 1a-c A-b and 3a-b. However, in this embodiment, the * Haizi 112 is arranged inside the mover 114, that is, the money m is essentially surrounding the stator 112. The stator m may include a plurality of stators: turns, and the specific embodiment ′ in the drawing includes three stator coils U8a_c. And this thin 91787.doc -24- 200425617 type, the linear motor can also be arranged as the only stator coil. The iron core 12a-c of the 4 iron core 112 can also be divided into a first stator component He and a second stator opening IM bull 122a-c similar to the square of the stator core previously described. The big difference between the linear motor and the stator of this specific embodiment in FIG. Η is that the teeth of the stator core 156a < and i58a c series, / σ ~ sub112 are arranged in a peripheral manner to enable the The mover 114 performs magnetic interaction. In addition, the comparison core ma_e can be designed in a manner similar to the aforementioned outer stator core, only in structure, because it needs to be able to magnetically interact with the _ outer mover 114 (non-inner mover). The difference. Therefore, it can be designed to have a variable axial tooth length, similar to the specific embodiment in FIG. 10, and have tooth protrusions, similar to the protrusions in the specific embodiment of FIG. Alas, the features of the outer stator cores described earlier apply to these inner stator cores i2〇a_c. -In the embodiment shown, the stator 112 includes an inner periphery 152 that defines an axial hole in the center of the stator core 120a-c. In another embodiment, there is no such axial hole, that is, each stator core 120a-c is a solid core having the same soft magnetic material as the other stator cores. The mover Π4 is made in a manner similar to the middle mover in Fig. 1a, except that the permanent magnets 128a-d are arranged inside a soft magnetic tube 126. The mover 114 can also be of the type described in Figs. 13a-bt, and such a mover can be used without any change.
