[0043] Please refer to Figure 1 and Figure 2 A multi-dimensional reluctance motor in a preferred embodiment of the present invention includes a mover center frame 100, a permanent magnet 200, a stator frame 300 and a flexible connection structure.

[0044] There are two permanent magnets 200 and they are symmetrically installed at the center of the front and rear sides of the mover center frame 100. There are two stator frames 300 and they are respectively located on the side of the two permanent magnets 200 away from the mover center frame 100, that is, the two stator frames 300 are respectively located on the opposite sides of the two permanent magnets 200. A single permanent magnet 200 is located between the stator frame 300 and the mover center frame 100. The stator frame 300 has multiple groups of iron cores 310 arranged around one side of the corresponding permanent magnet 200, and the two iron cores 310 of the same group are relatively arranged on the peripheral side of the permanent magnet 200, so as to surround the permanent magnet 200 and realize the driving of the permanent magnet 200 in multiple directions. A coil 320 is wound around the iron core 310, and the coil 320 is energized to form a magnetic field to drive the permanent magnet 200 to move.

[0045] There are two groups of flexible connection structures, and the two groups of flexible connection structures correspond to two stator frames 300 respectively. The two groups of flexible connection structures are used to connect the mover center frame 100 and the two stator frames 300 respectively. The two ends of the flexible connection structure can be elastically deformed in multiple directions to adapt to the multiple groups of iron cores 310 driving the permanent magnets 200 and the mover center frame 100 to move in different directions. And because the permanent magnets 200, the stator frames 300 and the flexible connection structures are symmetrically arranged, the flexible connection structures will generate derived displacement when they are bent. When they are symmetrically arranged, the pulling of the flexible connection structures on both sides can offset the derived displacement, and can also make the mover movement more accurate and stable.

[0046] The multi-dimensional reluctance motor realizes the ability of the mover to move in multiple directions by symmetrically installing two permanent magnets 200 on the mover center frame 100 and arranging multiple groups of iron cores 310 around the stator frame 300, meeting the needs of a multi-degree-of-freedom motion platform. The reluctance motor itself has the characteristics of high control flexibility and high efficiency, which enables the mover to move quickly and accurately in multiple directions; through two groups of flexible connection structures, it can be elastically deformed in multiple directions, which not only meets the needs of multiple groups of iron cores 310 driving permanent magnets 200 and the mover center frame 100 in different directions, but also enhances the stability and adaptability of the system.

[0047] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the multi-dimensional reluctance motor is a two-dimensional reluctance motor, and two groups of the iron core 310 are provided corresponding to one permanent magnet 200. One group of iron cores 310 includes two iron cores 310 and are arranged opposite to each other. The four iron cores 310 are arranged in the four directions of up, down, left and right of the corresponding permanent magnet 200, thereby driving the permanent magnet 200 and the mover center frame 100 to move in the two directions of up, down and left and right; one group of flexible connection structures includes four flexible rods 400, and the four flexible rods 400 are arranged around the corresponding permanent magnet 200, and the flexible rods 400 and the iron core 310 are circumferentially staggered. The mover center frame 100 and the stator frame 300 are connected by the four flexible rods 400, thereby realizing a flexible connection between the mover center frame 100 and the stator frame 300, thereby adapting to the relative movement of the mover center frame 100 relative to the stator frame 300.

[0048] Reference Figure 4In a further embodiment of the present invention, first grooves 410 are provided on the upper and lower sides of the flexible rod 400 to form a first flexible connection portion 411 between the two first grooves 410, and the first grooves 410 are used to achieve thinning processing, thereby forming a first flexible connection portion 411 with thinned thickness in the up and down directions, so that the two ends of the first flexible connection portion 411 can produce elastic relative deformation in the up and down directions within a certain range, thereby adapting to the up and down relative movement of the mover center frame 100 and the stator frame 300; second grooves 420 are provided on the left and right sides of the flexible rod 400 to form a second flexible connection portion 421 between the two second grooves 420, and the second grooves 420 are used to achieve thinning processing, thereby forming a second flexible connection portion 421 with thinned thickness in the left and right directions, so that the two ends of the second flexible connection portion 421 can produce elastic relative deformation in the left and right directions within a certain range, thereby adapting to the left and right relative movement of the mover center frame 100 and the stator frame 300. It is understandable that due to the action of the first flexible connection part 411 and the second flexible connection part 421, the two ends of the flexible rod 400 can be elastically deformed in the up-down direction and the left-right direction, that is, one end of the flexible rod 400 is fixed, and the other end can be elastically movable up-down or left-right. Usually, the stator frame 300 is fixed on the frame, so the end of the flexible rod 400 connected to the stator frame 300 can be considered fixed, and the end of the flexible rod 400 connected to the mover center frame 100 will move with the mover center frame 100 and thus elastically move relative to the other end, so that the flexible rod 400 can adapt to the relative movement in two dimensions, realize the stable connection between the mover center frame 100 and the stator frame 300, and make the multi-dimensional reluctance motor structure not cause structural instability or looseness due to multi-dimensional movement. The flexible rod 400 adopts a pull-to-pull design to offset the small displacement caused by bending.

[0049] Reference Figure 2 and Figure 5In a further embodiment of the present invention, the stator frame 300 is provided with a first connecting block 330, and the first connecting block 330 is provided with a first connecting hole 331 that runs horizontally through. A connecting plate 110 is provided at the center of the mover center frame 100, and a protruding second connecting block 111 is provided on the front and rear sides of the connecting plate 110, and the second connecting block 111 is provided with a second connecting hole 112 that runs vertically through. The end surface of one end of the flexible rod 400 is attached to the first connecting block 330 and is provided with a first threaded hole 430, and the first threaded hole 430 is aligned with the first connecting hole 331 and is installed with a matching fastener, which may be a screw that is compatible with the first threaded hole 430; the end surface of the other end of the flexible rod 400 is attached to the connecting plate 110, and the side surface of the other end of the flexible rod 400 is attached to the second connecting block 111 and is provided with a second threaded hole 440, and the second threaded hole 440 is aligned with the second connecting hole 112 and is installed with a matching fastener, which may be a screw that is compatible with the second threaded hole 440. Since the flexible rods 400 on both sides share a connecting plate 110 and need to be connected to the flexible rod 400, the connection between the flexible rod 400 and the connecting plate 110 cannot be end-face connection, but the connection is achieved by using the second connecting block 111 protruding on the side and the corresponding hole position set on the side of the flexible rod 400, so as to achieve the connection between the connecting plate 110 and the flexible rods 400 symmetrical on both sides, which is convenient for installation and structural layout. In addition, the two ends of the flexible rod 400 are respectively fitted with the connecting plate 110 and the first connecting block 330, which plays the role of axial positioning, so that the overall structure is compactly connected.

[0050] Reference Figure 4 In a specific embodiment of the present invention, the first groove 410 and the second groove 420 are arc grooves. The arc grooves make the thickness of the flexible rod 400 gradually thinned instead of suddenly, so that the first flexible connection part 411 and the second flexible connection part 421 are more durable and will not be easily damaged during elastic deformation, thereby improving the life of the equipment.

[0051] Reference Figure 2 , Figure 5 and Figure 6In a further embodiment of the present invention, a protrusion 311 protruding toward the permanent magnet 200 is provided at one end of the iron core 310 away from the stator frame 300, and the coil 320 is located between the protrusion 311 and the stator frame 300, thereby realizing axial positioning of the coil 320 and improving the stability of the installation of the coil 320. The movable center frame 100 is provided with a radial flange 120 corresponding to the protrusion 311, and the radial flange 120 is limited by the protrusion 311 on the circumferential side, thereby realizing the control of the movable stroke of the movable center frame 100 and the permanent magnet 200. The distance between the radial flange 120 and the protrusion 311 determines the movable stroke of the movable center frame 100 and the permanent magnet 200, thereby realizing the movable stroke control, avoiding the loss of control due to excessive stroke or the excessive deformation and damage of the flexible rod 400 caused by excessive stroke.

[0052] Reference Figure 7 and Figure 8 The present invention also provides a multi-degree-of-freedom motion platform, including a central platform 500 and a multi-dimensional reluctance motor, wherein the mover central frame 100 of the multi-dimensional reluctance motor is connected to the central platform 500, and the multi-dimensional reluctance motor is provided with a plurality of movers arranged around the center of the central platform 500, thereby driving the central platform 500 to achieve multi-dimensional motion by controlling the movement of the mover central frame 100 of the multi-dimensional reluctance motor.

[0053] Reference Fig. 9 In a further embodiment of the present invention, the movable center frame 100 is connected to the center platform 500 through a flexible connecting rod 600, and the two ends of the flexible connecting rod 600 can be elastically deformed in the up-down direction and the left-right direction, that is, the two ends of the flexible connecting rod 600 can be elastically deformed in the up-down direction or the left-right direction, so that when the movable center frame 100 moves up and down, it can drive the edge of the center platform 500 to move up and down. Since the other edges of the center platform 500 will be restricted by other movable center frames 100, the displacement of the edge of the center platform 500 will not be completely the same as that of the movable center frame 100, and position deviation will occur. The elastic deformation of the two ends of the flexible connecting rod 600 can well adapt to the displacement deviation. The flexible rod 400 and the flexible connecting rod 600 can be made of metal with good elastic deformation ability such as aluminum alloy or spring steel.

[0054] Reference Fig. 9In a further embodiment of the present invention, one end of the flexible connecting rod 600 is provided with a first connecting strip 610 arranged horizontally, and the other end is provided with a second connecting strip 620 arranged vertically. The first connecting strip 610 and the mover center frame 100 are provided with corresponding holes to be connected and fixed by fasteners; the second connecting strip 620 and the center platform 500 are provided with corresponding holes to be connected and fixed by fasteners. Specifically, a connecting column 520 is extended from the corner of the center platform 500, and the end of the connecting column 520 and the second connecting strip 620 are provided with corresponding holes to be connected and fixed by fasteners, and the first connecting strip 610 is arranged horizontally, and the second connecting strip 620 is arranged vertically, and the arrangement directions of the two are perpendicular, so that the fasteners can be staggered during installation, which is convenient for installation; the upper and lower sides of the flexible connecting rod 600 are provided with third grooves 630 to be connected between the two third grooves A third flexible connection part 631 is formed between the two fourth grooves 630, and a thinning process is performed by using the third groove 630, so as to form a third flexible connection part 631 with a thinned thickness in the vertical direction, so that both ends of the third flexible connection part 631 can produce elastic relative deformation in the vertical direction within a certain range, so as to adapt to the vertical relative movement of the moving sub center frame 100 and the center platform 500; the left and right sides of the flexible connection rod 600 are provided with fourth grooves 640 to form a fourth flexible connection part 641 between the two fourth grooves 640, and a thinning process is performed by using the fourth groove 640, so as to form a flexible connection rod 600 with a thinned thickness in the left and right directions, so that both ends of the flexible connection rod 600 can produce elastic relative deformation in the left and right directions within a certain range, so as to adapt to the horizontal relative movement of the moving sub center frame 100 and the center platform 500. In this way, it is avoided that the multiple moving sub center frames 100 around the center platform 500 rigidly drive the center platform 500 to move, causing motion interference and structural damage.

[0055] Reference Figure 7 and Figure 8In a further embodiment of the present invention, the multidimensional reluctance motor is provided with four motors and connected to the four corners of the central platform 500 respectively. Specifically, in the present embodiment, the multidimensional reluctance motor is a two-dimensional reluctance motor, which can only drive the vertical and horizontal movement of the movable central frame 100. The four corners of the central platform 500 can be driven by the corresponding two-dimensional reluctance motors. The four two-dimensional reluctance motors can drive the vertical and horizontal movement of the corners of the central platform 500. The horizontal movement of adjacent two-dimensional reluctance motors is perpendicular. Therefore, it can be understood that the four two-dimensional reluctance motors can drive the central platform 500 to move back and forth vertically and back and forth along the two vertical directions horizontally, that is, to realize movement along a three-axis coordinate system, and can translate along the X, Y, and Z axes of the three-axis coordinate system. The Z axis is vertical, and the X and Y axes are the horizontal movement directions of the two adjacent two-dimensional reluctance motors. When the two-dimensional reluctance motors at different positions drive the central platform 500 to realize movement in different directions, they can also drive the central platform 500 to realize rotation, that is, rotation around the X, Y, and Z axes, such as Figures 10 to 13 , which are various states of the motion of the central platform 500. By using a two-degree-of-freedom reluctance motor to build a six-degree-of-freedom motion platform, it is possible to achieve fast, accurate and flexible control of the motion platform.

[0056] The four corners of the central platform 500 are provided with L-shaped decoupling strip holes 510, so that a certain amount of deformation can be generated at the corners. When the central platform 500 realizes the translation of the four motors and the central platform 500 involves rotation, the movement decoupling, the central platform 500 is avoided from being damaged due to interference of the movement of the four motors.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
