Description

Technical Field

[0001] This utility model belongs to the field of electrostatic motor technology, and in particular relates to a modular, detachable electrostatic motor with a static rotor. Background Technology

[0002] As a power device that converts energy based on the principle of electrostatic induction, the electrostatic motor has been widely used in microelectromechanical systems (MEMS), precision instruments, and special drive equipment due to its unique advantages such as compact structure, low power consumption, and no electromagnetic interference. Its performance hinges on the matching degree of structural parameters between the stator and rotor. Key parameters such as the number, area, and arrangement of stator and rotor blades directly determine the motor's output torque, speed, and operational stability. Different application scenarios have significantly different requirements for these performance parameters.

[0003] Current electrostatic motors generally adopt an integrated structural design, such as Figure 1 As shown, the stator and rotor are vertically fixed to the same output shaft, forming an inseparable integral structure. While this design offers advantages in structural integrity and ease of assembly, it reveals several insurmountable drawbacks in practical applications: First, the flexibility of module replacement is extremely poor: because the stator and rotor are integrally formed or fixedly connected, it is impossible to disassemble or replace any one of the modules individually. When the application scenario requires adjustment of motor performance (such as adapting to different torque and speed requirements by changing the number and area of ​​blades), the existing design cannot achieve the simple operation of replacing only the stator or rotor module. It can only redesign and manufacture the entire motor, which greatly limits the adaptability and versatility of the motor.

[0004] Secondly, the maintenance costs are high and resources are wasted: If one of the stator or rotor modules is damaged during the use of the motor (such as blade wear or deformation), the damaged module cannot be replaced individually due to the integrated structure. The entire motor must be discarded and a new one purchased. This not only increases the user's operating costs and maintenance difficulty, but also wastes a large number of effective components, which does not conform to the design concept of energy conservation and environmental protection.

[0005] Secondly, the research and development and iteration efficiency is low: In the motor research and development stage, it is necessary to conduct repeated tests on stators and rotors with different parameter combinations to optimize performance. The current integrated design requires the manufacture of a complete motor for each parameter combination, which leads to a longer research and development cycle, increased testing costs, and seriously restricts the speed of performance iteration of electrostatic motors.

[0006] Finally, there is insufficient capacity to meet personalized needs: with the diversification of application scenarios, the performance requirements for electrostatic motors are becoming increasingly personalized and differentiated. Existing integrated structures cannot flexibly combine stator and rotor modules of different specifications according to specific user needs, making it difficult to achieve customized adaptation of motor performance and limiting the widespread application of electrostatic motors in more niche fields. In summary, the existing integrated structural design of electrostatic motors has significant shortcomings in terms of module replacement flexibility, maintenance convenience, R&D iteration efficiency, and personalized adaptability, failing to meet the demands of practical applications for flexible motor adaptation, low-cost maintenance, and efficient R&D. Therefore, there is an urgent need for a technical solution that allows for independent design and free combination of stator and rotor modules to address the aforementioned problems in the existing technology.

A first lower slot and a second lower slot are alternately arranged on the lower support frame. The first lower slot is electrically connected to the lower conductive wire. The lower end of the stator blade is alternately inserted into the first lower slot and the second lower slot. When the lower end of the stator blade is inserted into the first lower slot, it can be electrically connected to the lower conductive wire.

[0021] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0022] It should be noted that all directional and positional terms used in this utility model, such as "up," "down," "left," "right," "front," "back," "vertical," "horizontal," "inner," "outer," "top," "lower," "lateral," "longitudinal," and "center," are only used to explain the relative positional relationships and connection arrangements between components in a specific state (as shown in the accompanying drawings). They are merely for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. Furthermore, descriptions involving "first," "second," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0023] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] like Figures 2-11 As shown, a modular, detachable electrostatic motor with a stationary rotor includes: The rotor module 1 includes a rotor frame 102 and a plurality of rotor blades 101. The rotor blades 101 are evenly spaced on the rotor frame 102 along the circumferential direction and are made of conductive material. The stator module 2 includes a stator frame 203 and a plurality of stator blades 201. The stator blades 201 are evenly spaced along the circumferential direction on the stator frame 203. Brushes 202 are provided on the stator blades 201. Both the stator blades 201 and the brushes 202 are made of conductive material. Each stator blade 201 is divided into a positive stator blade group and a negative stator blade group with opposite polarities by a stator connecting line 204, and forms an electric field when connected to an external power source. And, output module 3, which includes: output shaft 301 and bearing 302, the output shaft 301 being disposed at the center of the rotor module 1, the rotor frame 102 being mounted on the output shaft 301, and the bearing 302 being mounted on the output shaft 301; The stator module 2 is fixedly mounted on the mounting surface, and the output shaft 301 is mounted on the mounting surface through the bearing 302 and is rotatably connected to the mounting surface, so that the output shaft 301 can rotate synchronously with the rotor module 1.

[0026] In the modular detachable electrostatic motor with a stator and rotor described in this utility model, by changing the structure of the stator frame 203 and independently fixing the rotor module 1 and stator module 2 to the mounting surface, the rotor module 1 and stator module 2 are fixed, while maintaining the ability of the rotor module 1 and output shaft 301 to rotate under the influence of the electric field. This design optimizes core dimensions such as functional adaptability, maintenance efficiency, and operational stability. Specifically: First, it solves the problem of difficult replacement of existing electrostatic motor modules, enabling free combination of stationary and rotor components: The core pain point of existing integrated designs is that the stationary and rotor cannot be separated. However, this utility model breaks this limitation structurally through the independent fixing of rotor module 1 and stationary module 2 and the linkage of rotor module 1 with output shaft 301. The rotor blades 101 and rotor frame 102 constitute an independent rotor module 1, and are only connected to output shaft 301 through rotor frame 102. When it is necessary to replace the rotor with a different number and area of ​​blades, it is not necessary to disassemble stationary module 2 or output module 3; it is only necessary to disconnect rotor frame 102 from output shaft 301. Replacement is simple and easy; at the same time, the stator module 2 is directly fixed to the mounting surface through the stator frame 203, and has no direct structural binding with the rotor module 1 and the output module 3. If the stator parameters need to be adjusted (such as changing the number of blade groups or optimizing the brush position), it can be replaced simply by disassembling the connection between the stator frame 203 and the mounting surface, without modifying the rotor or output shaft 301. Under this structural design, rotor modules 1 with different parameters (such as 12 blades and 16 blades) and stator modules 2 with different specifications (such as bipolar and multipolar grouping) can be freely combined without redesigning the overall structure, which effectively solves the compatibility defect of the existing technology that requires one parameter for one whole machine.

[0027] Secondly, it significantly reduces maintenance costs and resource waste: if the rotor blade 101 fails due to wear or deformation, only the rotor module 1 needs to be replaced, while the stator module 2 and output module 3 (output shaft 301, bearing 302, etc.) can continue to be used; if the stator brush 202 is worn or the stator blade 201 fails, only the stator module 2 needs to be replaced, without discarding the intact rotor module 1 and output module 3; this avoids the high replacement cost of the entire machine caused by "replacing everything if it is damaged" in the existing technology, and at the same time reduces the resource waste of discarded parts, which is especially suitable for cost-sensitive scenarios such as precision instruments and MEMS.

[0028] Third, it accelerates R&D iteration and reduces testing costs: In the electrostatic motor R&D stage, this design solves the efficiency pain point of existing integrated designs, where parameter adjustments require rebuilding the entire machine, through modular combination testing. R&D personnel can prefabricate multiple sets of rotor modules 1 (such as different blade areas and arrangement angles) and stator modules 2 (such as different polarity grouping methods and brush materials) with different parameters. By freely combining them, they can directly test the torque, speed, stability, and other performance of different combinations without having to make a separate motor for each set of parameters. This eliminates the process of repeated design, processing, and assembly of integrated motors, significantly shortens the performance optimization cycle, and reduces material waste and processing costs during the R&D process.

[0029] Fourth, it meets personalized needs and expands application scenarios: Addressing the shortcomings of existing technologies that "cannot be customized," this invention achieves precise matching of personalized needs through customizable module parameters and free combination of stator and rotor modules. In microelectromechanical systems (MEMS), if low torque and high speed output is required, it can be paired with a "few-blade rotor + high-density stator grouping"; in special drive equipment, if high torque and stable output are required, it can be paired with a "multi-blade rotor + wide-area stator blades"—different scenario requirements can be met simply through module combination, without the need for complete machine redesign. Because it can quickly adapt to different performance requirements, this motor can cover more sub-fields such as precision instruments (e.g., micro-sensor drives), medical equipment (e.g., small pump drives), and special electronic equipment (e.g., scenarios without electromagnetic interference), breaking through the bottleneck of "limited application scenarios" in existing integrated motors.

[0030] Fifth, optimize structural stability and ensure operational reliability: Based on modularity, this utility model adopts a "self-fixed + precise linkage" structural design, which balances disassembly flexibility and operational stability. The stator module 2 is directly fixed to the mounting surface, rather than relying on the output shaft 301 or the rotor frame 102, avoiding the problem of uneven electric field caused by stator vibration displacement during operation, and ensuring the stable driving force of the electric field on the rotor. The rotor frame 102 is directly connected to the output shaft 301, and the output shaft 301 is rotatably connected to the mounting surface through the bearing 302. This structure not only ensures the coaxiality of the rotor during rotation and reduces wear caused by eccentricity, but also efficiently transmits the rotational torque of the rotor to the output shaft 301, avoiding power loss and improving the stability of motor operation. At the same time, the stator blades 201 and brushes 202 are made of conductive materials and are clearly divided into positive and negative polarity groups through the stator connection line 204, ensuring the stable formation of the electric field when the external power supply is connected, and avoiding problems such as poor contact and leakage caused by the integrated conductive structure in the integrated frame.

[0031] Sixth, simplified assembly process and improved production efficiency: From a manufacturing perspective, this modular design also has the advantages of modular production and rapid assembly. Rotor module 1 (rotor blade 101 + rotor frame 102), stator module 2 (stator blade 201 + brush 202 + stator frame 203 + stator connecting wire 204), and output module 3 (output shaft 301 + bearing 302) can be mass-produced in a standardized manner. Compared with the "overall processing" of integrated motors, the production efficiency is higher and the quality is easier to control. During assembly, only three steps are required: connecting rotor module 1 to output shaft 301, fixing stator module 2 to the mounting surface, and connecting output shaft 301 to the mounting surface through bearing 302. Assembly can be completed in three steps without the need for complex overall debugging, which greatly reduces the assembly difficulty and time cost.

[0032] As a preferred example of this utility model, the output module 3 further includes: The base 303 is on which the bearing 302 is mounted and rotatably connected to the output shaft 301. The base 303 is fixedly mounted on the mounting surface.

[0033] Specifically, the output shaft 301 can be inserted into the inner ring of the bearing 302 and fixedly connected to the inner ring. The base 303 is fixedly connected to the outer ring of the bearing 302. In this way, the output shaft 301 can be integrated with the bearing 302 and the base 303, and integrated with the rotor module 1 through the rotor frame 102, and then installed on the mounting surface.

[0034] In this invention, the bearing 302 serves a positioning function during the assembly of the stationary rotor module, restricting the coaxial alignment of the stationary rotor module. Simultaneously, the rotor module 1 has a base 303, rotor blades 101 are fixedly connected to a support frame 102, the support frame 102 is fixedly connected to an output shaft 301, and the output shaft 301 is connected to the base 303 via the bearing 302, enabling independent rotation of the rotor module 1. This connection logic of "output shaft 301 - bearing 302 - base 303" allows the three components to be pre-assembled into an independent output module 3 in the factory, reducing on-site assembly steps. This is particularly suitable for mass production or scenarios requiring high assembly precision, avoiding structural deviations caused by on-site operational errors.

[0035] As an example of this utility model, the mounting surface can be a mounting surface formed on a separately set mounting plate, or it can be a mounting surface formed directly by means of a plane such as the ground, wall, or the surface of other mechanical parts, as long as it can achieve stable installation of each module in the modular detachable electrostatic motor.

[0036] This installation method reduces design and usage costs, adapts to different budgets and scenario requirements, enhances scenario adaptability flexibility, breaks through installation environment limitations, simplifies the installation process, improves ease of operation, and ensures installation stability and security, while taking into account different usage needs.

[0037] As a preferred example of this utility model, the static subframe 203 includes: The upper support frame 203a and the lower support frame 203b are in the shape of a ring. The stator connecting line 204 connects the stator blades 201 into a positive stator blade group and a negative stator blade group with opposite polarities by forming a ring-shaped wiring along the surfaces of the upper support frame 203a and the lower support frame 203b.

[0038] As a specific example of this utility model, the stator connection 204 includes: an upper conductive connection 204a and a lower conductive connection 204b; The upper conductive wire 204a is arranged in a ring shape along the surface of the upper support frame 203a. The lower conductive wire 204b is arranged in a ring shape along the surface of the lower support frame 203b. The stator blade 201 is disposed between the upper support frame 203a and the lower support frame 203b, and is connected to the upper conductive line 204a or the lower conductive line 204b, forming a positive stator blade 201a and a negative stator blade 201b arranged in a "positive-negative-positive-negative" interval.

[0039] In this invention, the traditional method of arranging conductive wires radially from the center to the surrounding area is changed to a method of wiring along the circumference. This wiring method can better adapt to the modular detachable electrostatic motor of the static rotor in this application, and the wiring method is simple and easy to implement.

[0040] As examples of this utility model, an annular upper mounting groove 203c can be provided on the upper support frame 203a, and the upper conductive wire 204a can be arranged within the upper mounting groove 203c. This creates a space within the upper mounting groove 203c to accommodate the upper conductive wire 204a and limits its movement, ensuring accurate and stable installation. Similarly, an annular lower mounting groove 203d can be provided on the lower support frame 203b, and the lower conductive wire 204b can be arranged within the lower mounting groove 203d.

[0041] Furthermore, a first upper slot 203e and a second upper slot 203f are alternately arranged on the upper support frame 203a. The first upper slot 203e is electrically connected to the upper conductive wire 204a. The upper end of the stator blade 201 is alternately inserted into the first upper slot 203e and the second upper slot 203f. When the upper end of the stator blade 201 is inserted into the first upper slot 203e, it is electrically connected to the upper conductive wire 204a. When the upper end of the stator blade 201 is inserted into the second upper slot 203f, it is not electrically connected to the upper conductive wire 204a. Similarly, a first lower slot 203g and a second lower slot 203h are alternately arranged on the lower support frame 203b. The first lower slot 203g is electrically connected to the lower conductive wire 204b. The lower end of the stator blade 201 is alternately inserted into the first lower slot 203g and the second lower slot 203h. When the lower end of the stator blade 201 is inserted into the first lower slot 203g, it is electrically connected to the lower conductive wire 204b. When the lower end of the stator blade 201 is inserted into the second lower slot 203h, it is not electrically connected to the lower conductive wire 204b.

[0042] As a preferred example of this utility model, snap-fit ​​pieces 201c are respectively provided at the upper and lower ends of the stator blade 201. The snap-fit ​​piece 201c at the upper end is inserted into the first upper snap-fit ​​groove 203e or the second upper snap-fit ​​groove 203f to realize the installation and fixation of the upper end of the stator blade 201, and the snap-fit ​​piece 201c at the lower end is inserted into the first lower snap-fit ​​groove 203g and the second lower snap-fit ​​groove 203h to realize the installation and fixation of the lower end of the stator blade 201.

[0043] Preferably, the second upper slot 203f is located inside the upper conductive line 204a, such as at the inner edge of the upper support frame 203a, and the first upper slot 203e is located outside the upper conductive line 204a; similarly, the second lower slot 203h is located inside the lower conductive line 204b, such as at the inner edge of the lower support frame 203b, and the first lower slot 203g is located outside the lower conductive line 204b. Thus, the upper conductive line 204a or the lower conductive line 204b can be used as a boundary to separate the first upper slot 203e, the second upper slot 203f, the first lower slot 203g, and the first lower slot 203e. The two slots 203h are arranged in categories and areas on the stator frame 203. During assembly, the stator blades 201 are simply installed into the slots in the upper support frame 203a and the lower support frame 203b in sequence. The stator blades 201 are automatically divided into positive stator blades 201a and negative stator blades 201b arranged at intervals in sequence, which is convenient for identification and assembly. The upper conductive wire 204a and the lower conductive wire 204b correspond to and connect multiple positive stator blades 201a in the positive stator blade group and multiple negative stator blades 201b in the negative stator blade group, respectively, forming a wire connection method of "positive on top and negative on the bottom" or "negative on top and positive on the bottom".

[0044] As a preferred example of this invention, the brush 202 is a roller brush, which contacts the rotor blades 101 via roller friction. This type of brush 202 can reduce noise when it contacts the rotor blades 101 and also serves a positioning and limiting function.

[0045] As some other examples of this utility model, the brush 202 can be made of flexible conductive material, and its specific structure is not limited. It is only necessary to ensure that the brush 202 can make stable contact with the rotor blade 101. At this time, an enhancement structure can also be set as needed to ensure the coaxiality between the stator module 2 and the rotor module 1.

[0046] As some examples of the present invention, the electrostatic motor described in this utility model can be used when the rotor module 1 and the stator module 2 are nested inside and outside, and the configuration of the rotor module 1 and the stator module 2 can be different. For example, the arrangement of the rotor blades 101 and the stator blades 201 can be either a circumferential array or a circular radial array.

[0047] It should be noted that the above-mentioned circumferential array refers to the rotor blades 101 or stator blades 201 being evenly spaced along the circumference of the circle, that is, along the tangent direction of the circle; the above-mentioned radial array refers to the rotor blades 101 or stator blades 201 being evenly spaced along the radial direction of the circle, that is, along the direction of the radius.

[0048] Furthermore, the present invention does not limit the shape of the rotor blade 101 and the stator blade 201. The shape of the rotor blade 101 and the stator blade 201 can be any one of the following: flat plate, fan-shaped, comb-shaped, hollow, etc.

[0049] As an example of the present invention, the present invention does not limit the number of rotor blades 101 and stator blades 201. It can be designed according to the output performance parameters of the electrostatic motor, such as output torque, rated speed, power density, as well as the structural dimension parameters of the electrostatic motor, such as rotor / stator outer diameter, axial height, as well as high voltage electric field parameters or processing and manufacturing parameters, operating environment, etc.

[0050] As an example of the present invention, the number of rotor modules 1 is at least one. When the number of rotor modules 1 is multiple, the multiple rotor modules 1 are longitudinally stacked along the axial direction of the output shaft 301.

[0051] In summary, the modular detachable electrostatic motor of this utility model eliminates the axial interference structure of the rotor module of the traditional electrostatic motor and ensures stable cooperation between the rotor module 1 and the stationary module 2 by maintaining a certain relative position with a third-party structure. It has the advantages of simple structure, easy implementation, strong functional adaptability, high maintenance efficiency and good structural stability.

[0052] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
