Technical Field
[0001] This utility model belongs to the field of magnetic levitation swing motor technology, and in particular relates to a magnetic levitation high-speed swing motor. Background Technology
[0002] Electric motors (small motors) are ubiquitous in daily life, and can be categorized into types such as carbon brush motors and brushless motors. Among them, carbon brush motors have long held a large market share due to their simple circuitry and low price. However, carbon brush motors have a significant drawback: a short lifespan. As usage time increases, the carbon brushes gradually wear down, eventually causing the motor to malfunction and affecting product stability.
[0003] In contrast, magnetic levitation high-speed swing motors have a longer lifespan due to their contactless design. Therefore, how to fully leverage the advantages of magnetic levitation high-speed swing motors in practical applications has become a question worthy of in-depth research.
[0004] To address the above issues, we propose a magnetically levitated high-speed swing motor. Utility Model Content
[0005] The purpose of this invention is to provide a magnetic levitation high-speed swing motor to solve existing problems.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a magnetic levitation high-speed swing motor, comprising a base, a main support, a stator assembly, and a mover assembly. The base consists of a front support and a rear support. The main support is connected to the base via four pillars and secured with base fixing screws. The stator assembly is composed of stacked silicon steel sheets and stator coils, and is snapped onto the base. The stacked silicon steel sheets are composed of several layers of silicon steel sheets with a thickness of 0.2-0.5mm, with a total thickness of 8-12mm. The mover assembly consists of four sets of mover magnets with a dual-magnetic layout, a swing spring assembly, and a swing rod. The main support and the swing rod are connected by a return spring.
[0008] A drive rod is provided at the middle of the upper end of the swing arm, and limiting assist components are provided on both sides of the swing arm; the upper end of the limiting assist component is fixedly connected to the main support, and the lower end abuts against the upper surface of the swing spring connecting component.
[0009] In one embodiment, the swing spring assembly includes a swing spring connector. Two sets of swing springs are provided on both sides of the swing spring connector. The upper parts of the two sets of swing springs are connected to the swing spring connector via a spring assembly fixing member in the order of upper swing spring sub-pressing plate, swing spring, swing spring connector, swing spring, and upper swing spring sub-pressing plate. The lower parts of the two sets of swing springs are fixed to form a moving element swing frame via a spring assembly fixing member in the order of lower swing spring sub-pressing plate, swing spring, swing spring fixing main plate, swing spring, and lower swing spring sub-pressing plate. The lower part of the swing spring fixing main plate is fixed to the rear bracket of the base by fixing screws.
[0010] In one embodiment, the moving magnet is fixed on the moving magnet base, the lower end face of the swing rod is fixedly connected to the moving magnet base through a limiting pin, the swing rod extends to the outside through the swing spring connector and the middle clearance groove of the main body bracket, and the swing rod is fixedly connected to the lower surface of the swing spring connector.
[0011] In one embodiment, the front center of the base front bracket is engaged with a wire groove, and the stator coil is located above the wire groove.
[0012] In one embodiment, one end of the reset spring is fixed to a spring fixing protrusion provided on the inner side of the top of the main body bracket, and the other end is fixed to a swing arm spring fixing protrusion.
[0013] In one embodiment, the front support of the base is provided with a swing spring fixing slot that matches the main swing spring fixing plate. The upper middle part of the main support is fixed with a limiting seat on both sides by limiting seat screws. The limiting seat is sleeved on the circumferential side of the swing rod and located below the return spring. The limiting seat, the main support and the limiting assist component are fixedly connected by fasteners.
[0014] This utility model has the following beneficial effects:
[0015] 1. Extended service life: The contactless magnetic levitation design avoids the lifespan limitations of traditional carbon brush motors caused by carbon brush wear, significantly improving the overall service life and operational stability of the motor.
[0016] 2. High efficiency and energy saving: The stacked silicon steel sheets of the stator module are composed of 29 silicon steel sheets of 0.3mm each. With the total thickness remaining at approximately 10mm, the magnetic conversion efficiency is effectively improved and energy consumption is reduced by reducing the thickness of each sheet and increasing the number of sheets, thus achieving a more energy-saving operating state.
[0017] 3. Enhanced driving force: The mover assembly adopts four sets of mover magnets with a dual-magnet layout. Combined with the sudden change magnetic field generated by the stator coil, it can form double the driving force, making the reciprocating motion of the mover stronger and improving the working efficiency of the motor.
[0018] 4. Stable and reliable swing performance: The swing spring assembly forms the mover swing frame through a specific stacking sequence and fixing method. Combined with the synergistic effect of the return spring and the limit seat, it ensures smooth swing of the swing arm, controllable stroke, and timely reset, reducing swaying and deviation during the movement.
[0019] 5. Stable structure and easy installation: Each component is precisely connected by screws, slots, etc., such as fixing the main support to the base and the locking of the swing spring to the main plate to the base. This not only ensures the stability of the overall structure, but also simplifies the installation process and facilitates production and assembly.
[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] Example 1
[0033] Please see Figures 1-5As shown, this utility model is a magnetic levitation high-speed swing motor, including a base, a main support 3, a stator assembly, and a mover assembly. The base consists of a front support 1 and a rear support 2. The main support 3 is connected to the base by four pillars and fixed with base fixing screws 7. The stator assembly consists of stacked silicon steel sheets 4 and stator coils 5, which are snapped onto the base. The stacked silicon steel sheets 4 are composed of several layers of silicon steel sheets with a thickness of 0.2-0.5mm, with a total thickness of 8-12mm. The mover assembly consists of four sets of mover magnets 15 with a double magnetic layout, a swing spring assembly, and a swing rod 17. The main support 3 and the swing rod 17 are connected by a return spring 21. The stacked silicon steel sheets 4 consist of 29 silicon steel sheets with a thickness of 0.3mm, with a total thickness of about 10mm. By reducing the thickness of each silicon steel sheet while keeping the total thickness unchanged, the number of silicon steel sheets is increased to improve the magnetic force conversion efficiency and make the operation more energy-efficient.
[0034] A drive rod 19 is provided at the middle of the upper end of the swing rod 17, and limit assist components 20 are provided on both sides of the swing rod 17; the upper end of the limit assist component 20 is fixedly connected to the main body bracket 3, and the lower end abuts against the upper surface of the swing spring connecting component 18.
[0035] Furthermore, the swing spring assembly includes a swing spring connector 18. Two sets of swing springs 11 are provided on both sides of the swing spring connector 18. The upper part of the two sets of swing springs 11 is connected to the swing spring connector 18 via a spring assembly fixing member 13 in the following order: upper swing spring sub-pressing plate 10, swing spring 11, swing spring connector 18, swing spring 11, upper swing spring sub-pressing plate 10. The lower part of the two sets of swing springs 11 is fixed to the moving element swing frame via a spring assembly fixing member 13 in the following order: lower swing spring sub-pressing plate 9, swing spring 11, swing spring fixing main plate 12, swing spring 11, lower swing spring sub-pressing plate 9. The lower part of the swing spring fixing main plate 12 is fixed to the rear bracket 2 of the base by fixing screws 8.
[0036] Furthermore, the mover magnet 15 is fixed on the mover magnet base 14, and the lower end face of the swing rod 17 is fixedly connected to the mover magnet base 14 through the limiting pin 16. The swing rod 17 extends to the outside through the swing spring connector 18 and the middle clearance groove of the main body bracket 3. The swing rod 17 is fixedly connected to the lower surface of the swing spring connector 18. Among them, there are four groups of moving magnets 15, each group adopts a planar double magnet method. The stator coil 5 generates different magnetic fields through the sudden change signal output by the circuit board. When the signal of the circuit board makes the magnetic field at point A of the laminated silicon steel sheet 4 the N pole, the magnetic fields at points B and C of the laminated silicon steel sheet 4 are the S poles respectively. The N pole of the magnetic field at point A of the laminated silicon steel sheet 4 attracts each other with the S pole of the magnetic field of segment F of the magnet. The S pole of the magnetic field at point C of the laminated silicon steel sheet 4 attracts each other with the N pole of the magnetic field of segment G of the moving magnet 15, causing the moving magnet base 14 to move to the left. Similarly, the left moving magnet 15 is pushed to the left with double force and moves to the left. Conversely, it moves to the right.
[0037] Furthermore, the front support 1 of the base is snapped into the wire groove 6 at the center of the front side, and the stator coil 5 is located above the wire groove 6.
[0038] Furthermore, one end of the return spring 21 is fixed to the spring fixing protrusion 25 provided on the inner side of the top of the main body bracket 3, and the other end is fixed to the swing arm spring fixing protrusion 26.
[0039] Furthermore, both the front support 1 and the rear support 2 of the base are provided with swing spring fixing slots 24 that match the main swing spring fixing plate 12. The upper middle part of the main support 3 is fixed with limit seats 23 by limit seat screws 22. The limit seats 23 are sleeved on the side of the swing rod 17 and located below the return spring 21. The limit seats 23, the main support 3 and the limit assist component 20 are fixedly connected by fasteners. The limit seats 23 make the limit assist component 20 generate double the force on both sides to push the swing rod 17 to move.
[0040] In use, a positive current is first passed into the stator coil 5. Under the action of the current magnetic effect, the stator coil 5 and the laminated silicon steel sheet 4 work together to form an induced magnetic field. The moving magnet 15 cuts the induced magnetic field, so that one set of moving magnets 15 moves in the forward direction and the other set moves in the reverse direction, forming an alternating reciprocating motion; thus enabling the rocking motor to achieve the function of high-speed rocking.
[0041] Example 2
[0042] This embodiment describes the installation steps of a magnetic levitation high-speed swing motor:
[0043] 1. Assemble the base and stator assembly
[0044] Place the rear support 2 of the base horizontally and insert the stacked silicon steel sheet 4 (29 0.3mm silicon steel sheets stacked to a thickness of 10mm).
[0045] The stator coil 5 is mounted on the laminated silicon steel sheet 4, and the lead wire passes through the wire groove 6.
[0046] Cover the front bracket 1 of the base, align it with the slot and press it firmly to ensure that the stator assembly is fixed without loosening.
[0047] 2. Install the moving part swing mechanism
[0048] Installation of mover magnet holder 14:
[0049] Four sets of moving magnets 15 are fixed on the moving magnet base 14 according to the polarity (NS alternating) of the "planar double magnetic layout".
[0050] Assembly of the swing spring holder:
[0051] Upper part: Stack the upper swing spring plate 10, swing spring 11, swing spring connection 18, swing spring 11, and upper swing spring plate 10 in sequence, and lock them with the spring assembly fastener 13.
[0052] Lower part: Stack the lower swing spring auxiliary pressure plate 9, swing spring 11, swing spring fixing main plate 12, swing spring 11, and lower swing spring auxiliary pressure plate 9 in sequence, and lock them with the spring assembly fixing piece 13.
[0053] Insert both ends of the swing spring fixing main piece 12 at the bottom of the spring holder into the swing spring fixing slots 24 of the front bracket 1 and the rear bracket 2 of the base, and tighten them with the swing piece fixing screws 8.
[0054] 3. Connection between the rocker arm and the transmission mechanism
[0055] The lower end of the swing arm 17 is fixed to the mover magnet seat 14 by the limiting pin 16.
[0056] The through-hole swing spring connector 18 avoidance groove ensures a rigid connection with the spring holder.
[0057] A drive rod 19 is installed at the upper end of the swing arm 17, and limit assist components 20 are installed on both sides (upper fixed main body bracket 3, lower abutting swing spring connecting component 18).
[0058] 4. Installation of main support frame
[0059] Insert the four pillars of the main support 3 into the front and rear supports of the base, and fix them with the base fixing screws 7.
[0060] Install a limiting seat 23 on the top of the main support 3 (fixed with limiting seat screw 22) and fit it on the outside of the swing rod 17.
[0061] 5. Reset system installation
[0062] One end of the return spring 21 is fitted onto the spring fixing protrusion 25 on the inner side of the main body bracket 3, and the other end is fitted onto the swing rod spring fixing protrusion 26 on the upper side wall of the swing rod 17.
[0063] Ensure that the springs are symmetrically distributed and the tension is uniform.
[0064] 6. Final debugging
[0065] Check the clearance between the mover and stator to ensure there is no mechanical contact.
[0066] Manually push the drive rod 19 gently to check whether the swing arm 17 swings smoothly from left to right and whether the return spring 21 can return to the center in time.
[0067] Power-on test: Input alternating current into stator coil 5 and observe whether the swing arm 17 swings smoothly from left to right.
[0068] Key Considerations
[0069] 1. Magnetic pole alignment: The N / S poles of the mover magnet 15 must match the stator magnetic field, otherwise the thrust will be weakened.
[0070] 2. No-contact principle: All moving parts (moving element, rocker arm) must not touch the stator or base.
[0071] 3. Spring preload: The swing spring (11) must be pressed evenly to avoid skewness leading to wear.
[0072] 4. Overhead protection: The stator coil conductors must be fully embedded in the overhead slot (6) to prevent them from being pulled during swinging.
[0073] This installation method relies on the principle of magnetic levitation (no mechanical contact between the moving part and the moving part), and achieves smooth swing through the spring assembly. The return spring and limit seat control the stroke, which significantly improves the lifespan compared to carbon brush motors and significantly reduces noise.
