Description

Technical Field

[0001] This application belongs to the field of fluid boosting and conveying technology, specifically relating to a fluid boosting connector and a motor. Background Technology

[0002] Traditional axial-flow motors mostly rely on mechanical bearings to support the rotor and complete the electromechanical energy conversion through brushes and commutators. Their internal structure includes rolling bearings, transmission components, and winding systems. Due to frictional losses and wear caused by mechanical contact, these motors have significant shortcomings in terms of operating efficiency, vibration and noise, and maintenance costs. In addition, common fluid booster devices are usually designed separately from the drive motor, requiring additional impellers or pump bodies, resulting in low system integration, large size, limited efficiency, and easy wear and leakage risk at mechanical seals.

[0003] Compared to traditional axial-flow motors, field-modulated motors achieve rotor levitation and drive without mechanical contact by introducing modulated pole teeth or permanent magnet arrays into the air gap and combining them with magnetic levitation support technology. These motors offer advantages such as high torque density, wide speed range, and low energy consumption, and have gained widespread attention in fields such as electric vehicles, industrial automation, and wind power. However, existing field-modulated motors mostly focus on simple drive functions, and their deep integration with fluid pressurization systems, as well as size and structural optimization, still require further exploration. On the other hand, while rim-driven axial-flow propellers (also known as rim-driven motors) achieve a compact design integrating the motor and impeller, they are currently mainly used in marine propulsion, with a relatively bulky structure and lacking customized improvements for the specific needs of fluid pressurization within pipelines. Utility Model Content

[0004] The embodiments of this application are intended to at least improve one of the technical problems existing in the prior art or related art.

[0005] In view of this, the object of the embodiments of this application is to provide a fluid booster connector.

[0006] Another object of embodiments of this application is to provide an electric motor.

[0007] To achieve the above objectives, a fluid booster connector is provided according to the first aspect of this application, comprising: a base; a stator assembly disposed in the base, the stator assembly including a permanent magnet stator, an electric drive winding and a magnetic field modulation unit, the magnetic field modulation unit being used to generate a spatially vector controllable electromagnetic field; a rotor disposed inside the stator assembly, the rotor having a rotor permanent magnet and a cavity structure inside the rotor matching the fluid flow channel; and a flanged fan blade coaxially disposed with the rotor and connected to the inner side of the rotor.

[0008] The fluid booster connector provided in this application includes a base, a stator assembly, a rotor, and flanged fan blades. The stator assembly is housed in the base and includes a permanent magnet stator, an electric drive winding, and a magnetic field modulation unit. The magnetic field modulation unit generates a spatially vector-controllable electromagnetic field. The rotor is located inside the stator assembly and has a rotor permanent magnet. The rotor employs magnetic field modulation technology, precisely modulating the frequency, intensity, and phase of the magnetic field to generate controllable electromagnetic force, thereby achieving contactless levitation and drive of the rotor, while eliminating mechanical friction, ultimately achieving a bearingless design. The rotor has an internal cavity structure that matches the fluid flow channel, ensuring stable fluid flow within the rotor. The flanged fan blades are installed inside the rotor and rotate with it. The fluid booster connector provided in this application utilizes the principle of magnetic field modulation to achieve contactless levitation and rotational drive of the rotor and flanged fan blades, thereby achieving efficient pressurized fluid delivery, eliminating mechanical friction loss and leakage risks, and improving system reliability and energy efficiency.

[0009] Specifically, an alternating current is applied to the stator windings, generating a rotating magnetic field. Permanent magnets or magnetic poles coupled to the stator magnetic field are arranged on the rotor. Through magnetic field modulation technology, a changing magnetic flux coupling is formed between the stator and rotor, generating a driving torque to rotate the rotor. Since the rotor does not require traditional bearing support, its inertia and external forces are mainly balanced by the magnetic levitation support system, achieving contactless rotation. When the impeller rotates with the rotor, the liquid in the pipeline enters from the pump inlet and moves along the axial flow channel of the rim-type impeller. During impeller rotation, the rim structure increases the centrifugal and axial forces on the fluid, thereby increasing the pressure and flow rate at the liquid outlet. Throughout the process, energy loss is reduced due to the absence of mechanical contact friction, while the magnetic levitation support reduces vibration and noise, ensuring the stability and lifespan of the system.

The stator sealing rings are located at both ends of the stator base, effectively isolating the fluid passage from the electromagnetic levitation system and ensuring that the internal core components are protected from liquid intrusion, thereby achieving reliable operation under high-pressure conditions.

The stator assembly 120 is disposed within the base 110 and includes a permanent magnet stator 122, an electric drive winding 124, and a magnetic field modulation unit 126. The magnetic field modulation unit 126 generates a spatially vector-controllable electromagnetic field. The rotor 130 is disposed inside the stator assembly 120 and has a rotor permanent magnet 132. The rotor 130 employs magnetic field modulation technology to generate controllable electromagnetic force by precisely modulating the frequency, intensity, and phase of the magnetic field, thereby achieving contactless levitation and drive of the rotor 130, while eliminating mechanical friction and ultimately achieving a bearingless design. The rotor 130 has an internal cavity structure that matches the fluid flow channel, ensuring stable fluid flow within the rotor 130. The flanged fan blade 140 is installed inside the rotor 130 and rotates with the rotor 130.

[0036] Specifically, an alternating current is applied to the stator windings, generating a rotating magnetic field. Permanent magnet materials or magnetic pole pieces coupled to the stator magnetic field are arranged on the rotor 130. Through magnetic field modulation technology, a changing magnetic flux coupling is formed between the stator and rotor 130, generating a driving torque to rotate the rotor 130. Since the rotor 130 does not require traditional bearing support, its inertia and external forces are mainly balanced by the magnetic levitation support system, achieving contactless rotation. When the impeller rotates with the rotor 130, the liquid in the pipeline enters from the pump body inlet and moves along the axial flow channel of the rim-type impeller. During impeller rotation, the rim structure increases the centrifugal and axial forces on the fluid, thereby increasing the pressure and flow rate at the liquid outlet. Throughout the process, energy loss is reduced due to the absence of mechanical contact friction, while the magnetic levitation support reduces vibration and noise, ensuring the stability and lifespan of the system.

[0040] In some embodiments, the flanged fan blade 140 is integrally formed with the rotor 130 to ensure the structural strength and stability of the fan blade.

[0041] In some embodiments, the rotor permanent magnet 132 may optionally include permanent magnet material or magnetic pole pieces. The rotor 130 is provided with permanent magnet material or magnetic pole pieces coupled to the stator magnetic field.

The stator base 112 does not participate in magnetic field modulation, but only provides mechanical support. The low-permeability metal base 110 is used to avoid magnetic circuit interference and suppress eddy current losses.

Standard flange joints are fitted at the inlet end of the cover and the outlet end of the base 110, respectively, and system integration is achieved through pipe connection.

[0045] like Figure 6 As shown, an embodiment of the second aspect of this application provides a motor 20, including a fluid booster connector 10 as described in any of the above embodiments.

[0046] The motor 20 provided according to the embodiments of this application includes the fluid booster connector 10 as described in any of the above embodiments, and thus has all the beneficial effects of the fluid booster connector 10 as described in any of the above embodiments, which will not be repeated here.

[0047] like Figures 1 to 9As shown, the fluid booster connector 10 according to a specific embodiment of this application utilizes the principle of magnetic field modulation to achieve contactless suspension and rotational drive of the rotor 130 and the fan blade assembly, thereby achieving efficient booster delivery of fluid, eliminating mechanical friction loss and leakage risks, and improving the reliability and energy efficiency of the system.

[0048] The fluid booster connector 10 includes a stator assembly 120, a rotor 130 and a fan blade assembly, a motor 20 sealing assembly, and a connecting assembly 150.

[0049] (1) Stator assembly 120: such as Figure 7 , Figure 8 and Figure 9 As shown, the stator assembly 120 consists of a permanent magnet stator 122, an electric drive winding 124, and a magnetic field modulation unit 126. The angle θ represents the range of the magnetic field modulation unit under different winding methods. The stator assembly 120 is placed in the base 110 of the motor 20 through a clearance fit.

[0050] (2) Rotor 130 and fan blade assembly: The rotor 130 adopts magnetic field modulation technology. By precisely modulating the frequency, intensity and phase of the magnetic field, a controllable electromagnetic force is generated, thereby realizing the contactless suspension and drive of the rotor 130, while eliminating mechanical friction, and finally achieving the purpose of bearingless design. The rotor 130 has a cavity structure that matches the fluid flow channel to ensure that the fluid can flow stably inside the rotor 130.

[0051] Meanwhile, the flange-type fan blade 140 is installed inside the rotor 130 by bolt connection and rotates together with the rotor 130; the flange-type fan blade 140 adopts an integrated design with the rotor 130 to ensure the structural strength and stability of the fan blade.

[0052] (3) Base 110 and sealing assembly: The base 110 assembly consists of a stator base 112, a stator cover 114, and a stator sealing ring 116. The stator base 112 serves as the basic support structure for the stator assembly 120, and has internal slots for stator installation. The stator base 112 does not participate in magnetic field modulation, but only provides mechanical support; therefore, a material with low permeability and high mechanical strength is selected to avoid magnetic circuit interference and suppress eddy current losses. The stator cover 114, in conjunction with the stator base 112, provides protection and support for internal components, while also achieving magnetic field sealing. The stator sealing ring 116 is installed at both ends of the stator base 112 via an interference fit to ensure the airtightness of the internal flow channels.

[0053] (4) Connecting component 150: In this embodiment, the connecting component 150 is used to connect the motor 20 to different pipes. The inlet connector 152 is integrated into one end of the stator assembly 120 as a fluid inlet connecting component; the outlet connector 154 is integrated into the other end of the stator assembly 120 as a fluid outlet connecting component.

[0054] The working principle of this embodiment is as follows: The working principle of this embodiment is based on magnetic field modulation and rim-type impeller structure.

[0055] Specifically, an alternating current is applied to the stator windings to generate a rotating magnetic field. The rotor 130 is equipped with permanent magnet materials or magnetic poles coupled to the stator magnetic field. Through magnetic field modulation technology, a changing magnetic flux coupling is formed between the stator and rotor 130, generating a driving torque to rotate the rotor 130. Since the rotor 130 does not require traditional bearing support, its inertia and external forces are mainly balanced by the magnetic levitation support system, enabling contactless rotation.

[0056] As the impeller rotates together with the rotor 130, the liquid in the pipeline enters from the pump body inlet and moves along the axial flow channel of the rim-type impeller. During impeller rotation, the rim structure increases the centrifugal and axial forces acting on the fluid, thereby increasing the pressure and flow rate at the liquid outlet. Throughout the process, the absence of mechanical contact friction reduces energy loss, while the magnetic levitation support reduces vibration and noise, ensuring system stability and lifespan.

[0057] To prevent high-pressure liquid from leaking along the axial or radial direction, this embodiment is equipped with an axial sealing ring to effectively isolate the fluid channel from the electromagnetic levitation system, ensuring that the internal core components are protected from liquid intrusion, thereby achieving reliable operation under high-pressure conditions.

[0058] Employing a rim-type shaftless structure and magnetic field modulation drive technology, the device boasts a compact structure, small size, and easy installation. Its modular design facilitates manufacturing and maintenance, enhancing system maintainability and flexibility. The contactless drive method reduces mechanical friction loss and wear, improving energy efficiency and operational efficiency while lowering noise and vibration. Dynamic and efficient pressurization can be achieved by controlling magnetic field and current parameters. Suitable for pipeline liquid pressurization applications requiring high reliability, high sealing, and long service life, such as municipal water supply, industrial circulating cooling, gas pressure regulation, and chemical process control, it solves the problems of low efficiency and difficult maintenance associated with traditional pumps in these applications.

[0059] Applications of general fluid booster systems: In this embodiment, the rim-type axial flow booster motor 20 is applied to industrial pipeline fluid pressurization scenarios (such as central air conditioning circulating water systems). The implementation steps are as follows: A stator base 112 made of low permeability metal material is provided, and a stator assembly 120 including a permanent magnet stator 122, an electric drive winding 124 and a magnetic field modulation ring is installed into the cavity of the base 110 in a clearance fit manner. The flanged fan blades 140 are cut from corrosion-resistant alloy sheet and rigidly connected to the permanent magnet rotor 130 by surface-treated fastening bolts. The assembled fan blade-rotor 130 assembly is axially inserted into the inner ring of the stator, ensuring that the rotor 130 cavity is coaxially aligned with the fluid channel; Install the stator cover 114 assembly and fasten it to the stator base 112 using a bolt array. At the same time, embed double elastic sealing rings on the mating surface to form an end face seal. Standard flange connectors are installed at the inlet end of the cover and the outlet end of the base 110, respectively, and system integration is achieved through pipe connection. After being powered on, the magnetic field modulation unit 126 generates a spatially vector controllable electromagnetic field, which drives the rotor 130 to achieve contactless levitation rotation, and the fluid in the pipeline is pressurized by the fan blades and then output in a directional manner.

[0060] Through the above implementation, the obtained rim-type axial flow pressurizing motor 20 utilizes magnetic field modulation technology in industrial pipelines to eliminate mechanical friction losses, enabling the conversion efficiency of electrical energy to fluid kinetic energy to break through the limitations of traditional bearings; the sealing ring and the low magnetic permeability metal base 110 work together to ensure long-term leak-proof operation under high flow conditions; at the same time, the standardized flange interface enables ready-to-use system integration, significantly reducing the complexity of modification and maintenance costs of industrial facilities such as water supply networks and HVAC circulation systems.

[0061] Small capillary system pressurized conveying applications: In this embodiment, motor miniaturization is applied to capillary-level fluid actuation of microfluidic chips (such as microchannels in medical testing equipment). The implementation steps are as follows: A miniature titanium alloy stator base 112 is fabricated using precision machining technology, and a miniature stator assembly 120 is installed into the base; In an ultra-clean environment, millimeter-sized titanium alloy fan blades are assembled with micro-screws to micro-rotor 130 to ensure dynamic balance accuracy. A biocompatible silicone sealing ring is embedded in the base sealing groove, and optical alignment technology is used to ensure uniform compression of the sealing surface; Replacing traditional flanges with capillary quick-connect interfaces, a tapered self-locking structure enables leak-free connection of micro-pipes; The rotor 130 is driven by a high-frequency magnetic field modulation strategy, and the suspension gap is adjusted in real time by a closed-loop control algorithm. By setting flow parameters through a programming interface, the fan blades are controlled to apply stable pressure to the micro-level fluid at a precise rotation speed.

[0062] Through the above implementation, the miniaturized rim-type axial flow pressurizing motor in the capillary system achieves micron-level suspension accuracy within millimeter-level flow channels and eliminates nano-mechanical vibration interference. Furthermore, it employs a biocompatible design to avoid contaminating sensitive fluids. The capillary quick-connect interface supports rapid replacement of microfluidic chips and system expansion. In addition, through intelligent algorithms that dynamically compensate for fluid viscosity changes, it maintains ±1% pressure stability at flow rates in the microliter / minute range, providing a disruptive driving solution for scenarios such as medical diagnostics and chip labs.

[0063] In summary, the beneficial effects of the embodiments of this application are as follows: 1. Adopting a rim-type shaftless structure and magnetic field modulation drive technology, the device has a compact structure, small size, and is easy to install.

[0064] 2. The modular design facilitates manufacturing and maintenance, improving system maintainability and flexibility.

[0065] 3. The use of a contactless drive method reduces mechanical friction loss and wear, improves energy efficiency and operating efficiency, and reduces noise and vibration.

[0066] 4. Dynamic and efficient boosting can be achieved by controlling the magnetic field and current parameters.

[0067] 5. It is suitable for pipeline liquid pressurization applications that require high reliability, high sealing and long service life, such as municipal water supply, industrial circulating cooling, gas pressure regulation and chemical process control, and solves the problems of low efficiency and difficult maintenance of traditional pumps in these applications.
