Description

Technical Field

[0001] The invention relates to a reluctance motor, in particular to a pump-type reluctance motor having the functions of a motor and a pump, and belongs to the field of power equipment. Background Art

[0002] The reluctance motor is a continuously running electrical drive device, and is a power device that generates torque based on the "principle of minimum reluctance". The so-called "principle of minimum reluctance" is that the magnetic flux always closes along the path with the minimum reluctance, thereby generating magnetic pull, and then forming an electromagnetic torque of reluctance nature, and the magnetic lines of force have the nature of trying to shorten the magnetic flux path to reduce reluctance and increase magnetic permeance. When the top of the rotor teeth of the reluctance motor is in a state of facing the top of the stator teeth, the center lines of the magnetic poles coincide, but when the rotor rotates through a certain angle, the magnetic lines of force are twisted, and the magnetic resistance of the closed loop of the magnetic lines of force should be the minimum, so a tangential reluctance torque is generated. Under the action of the reluctance torque, the rotor rotates, trying to return to the state where the center lines of the magnetic poles coincide. When the stator is in three-phase, two-phase or single-phase capacitor phase operation, a rotating magnetic field is generated in the space inside the stator. The rotation of the rotating magnetic field is equivalent to the rotation of the stator's magnetic poles. When the rotor is stationary, the above-mentioned magnetic lines of force will inevitably be twisted between the stator's magnetic poles and the rotor, thereby generating a magnetic resistance torque. Under the action of the magnetic resistance torque, the rotor rotates in the direction of the rotating magnetic field.

[0003] At present, most of the existing pumps and motors adopt a split design, that is, an independent motor drives an independent pump to work. This traditional driving method has a lot of energy loss in the transmission process, and the motor and pump occupy their own space, resulting in a large overall volume of the equipment and a complex overall structure. With the vigorous development of the industrial control industry, the application field of motors is constantly expanding. At the same time, in order to meet the needs of different working conditions, motors are developing in the direction of lightweight, integration, and modularization, so as to achieve higher power output in a smaller space and realize more functions.

DETAILED DESCRIPTION

[0032] The following is a detailed description with reference to the accompanying drawings.

[0033] like Figures 1 to 4 As shown, the pump-type reluctance motor of the present invention includes a pump-type reluctance motor housing 100, a pump-type reluctance motor stator 200 is arranged in the pump-type reluctance motor housing 100, a pump-type reluctance motor rotor 300 is arranged in the pump-type reluctance motor stator 200, the pump-type reluctance motor stator 200 includes a stator yoke 210, a plurality of stator teeth 211 extending in the axial direction are arranged on the inner side of the stator yoke 210 along the circumferential ring, a stator winding 212 is arranged on the stator teeth 211, and a stator flow channel 213 is arranged between circumferentially adjacent stator windings 212, and the pump-type reluctance motor rotor 300 includes a rotor yoke 301, a plurality of rotor teeth 311 extending in the axial direction are arranged on the outer side of the rotor yoke 301 along the circumferential ring, a rotor flow channel 330 is arranged between circumferentially adjacent rotor teeth 311, and a flow channel bottom surface 331 of the rotor flow channel 330 extends obliquely toward the inner side of the stator yoke 210 along the fluid conveying direction in the pump-type reluctance motor.

[0034] The above solution combines a liquid pump with a reluctance motor. Based on the characteristics of the reluctance motor's rotor salient pole structure, the pump and motor are designed as an integrated unit, with the reluctance motor's rotor acting as the pump's impeller and the reluctance motor's stator acting as the pump's cavity. The rotation of the rotor compresses and releases the gaps in different parts of the cavity, thus achieving the function of extracting liquid or gas. Figure 3 As shown, when the tooth top of the rotor tooth 311 is in a directly facing state with the tooth top of the stator tooth 211, the center lines of the magnetic poles coincide, but when the above two are offset by a certain angle, the magnetic lines of force are twisted. According to the "minimum magnetic resistance principle", the magnetic resistance of the closed loop of magnetic lines of force should be minimum, so a tangential magnetic resistance torque is generated on the rotor tooth 311. Under the action of the magnetic resistance torque, the rotor 300 of the pump-type reluctance motor rotates, striving to return to the state where the center lines of the magnetic poles coincide. When the pump-type reluctance motor stator 200 is in three-phase, two-phase or single-phase capacitor split-phase operation, a rotating magnetic field is generated therein, which is equivalent to the magnetic poles of the pump-type reluctance motor stator 200 rotating. When the pump-type reluctance motor rotor 300 is stationary, the magnetic lines of force are inevitably twisted between the magnetic poles of the pump-type reluctance motor stator 200 and the pump-type reluctance motor rotor 300, thereby continuously generating a magnetic resistance torque on the rotor teeth 311. Under the action of the magnetic resistance torque, the pump-type reluctance motor rotor 300 rotates in the direction of the rotating magnetic field. Figure 4As shown, the continuously rotating pump-type reluctance motor rotor 300 stirs the fluid in the reluctance motor through the rotor teeth 311, so that the fluid moves radially toward the periphery of the rotor flow channel 330 under the action of centrifugal force. Based on the structure of the flow channel bottom surface 331 of the rotor flow channel 330 extending obliquely from upstream to downstream in the fluid conveying direction toward the inner side of the stator yoke 210, the flow velocity of the fluid gradually increases from upstream to downstream, and the pressure gradually decreases, thereby forming an axial flow force from upstream to downstream. Under the action of the axial flow force, the fluid flows through the rotor flow channel 330 and the stator flow channel 213, thereby realizing the function of the pump. Therefore, this solution overcomes the problems of large energy loss, large overall equipment space occupation, and complex structure caused by the separate design of the pump and the motor in the existing similar solutions, and has the characteristics of small energy loss, small overall equipment space occupation, simple, compact, reliable structure, good heat dissipation effect, and long service life.

[0035] Based on the above scheme, in order to keep the internal flow of the pump-type reluctance motor smooth and meet the pump flow requirements, such as Figure 3 As shown, in the present embodiment, a tooth tip gap is provided radially between the tooth tip of the stator tooth 211 and the tooth tip of the rotor tooth 311, and a tooth yoke gap is provided radially between the tooth tip of the stator tooth 211 and the flow channel bottom surface 331 of the rotor flow channel 330, and the radial width of the tooth yoke gap is not less than 20 times the radial width of the tooth tip gap.

[0036] In order to realize the inlet docking function, promote the stable flow of fluid and reduce energy loss, the present invention discloses an inlet component suitable for the above-mentioned pump-type reluctance motor, such as Figure 1 , 2 As shown in , 7, the pump-type reluctance motor also includes a pump-type reluctance motor inlet component 400, and the pump-type reluctance motor inlet component 400 includes a speed regulating interface 410 and a flow deflector assembly 401. The speed regulating interface 410 is connected to the inlet of the flow deflector assembly 401, and the outlet of the flow deflector assembly 401 is connected to the inlet end of the pump-type reluctance motor end cover 110 of the pump-type reluctance motor housing 100. The speed regulating interface 410 can adjust the flow rate and flow velocity of the fluid flowing into the entire pump-type reluctance motor, and can adapt different types of interfaces according to different external connectors to ensure reliable connection and stable flow. The flow deflector assembly 401 is used to guide the fluid flowing into the pump-type reluctance motor, so that the fluid flows into the pump-type reluctance motor end cover 110 in an orderly manner, reducing flow resistance and energy loss.

[0037] Based on the above scheme, in order to realize the function of the speed control interface 410, this scheme discloses a specific interface structure, such as Figure 2 , 5As shown, the speed regulating interface 410 includes an inlet interface section 411, a connecting section 412, and a shroud interface section 413. The outer side of the end of the inlet interface section 411 is provided with an external thread, the inner side of the shroud interface section 413 is provided with an internal thread, the outer side of the shroud interface section 413 is provided with an anti-skid pattern, and a plurality of wedge-shaped reinforcing ribs are connected between the connecting section 412 and the shroud interface section 413. The outer side external thread of the end of the inlet interface section 411 is used to connect with an external fluid pipeline, and the inner side internal thread of the shroud interface section 413 is used to connect with the interface of the shroud assembly 401. However, the above connection method is not limited to threaded connection, and can also be any other connection method that can achieve sealed communication. The outer side anti-skid pattern of the shroud interface section 413 facilitates the component connection operation and avoids slipping. The wedge-shaped reinforcing ribs between the connecting section 412 and the shroud interface section 413 improve the overall structural performance of the component and increase the service life.

[0038] In order to realize the functions of the air deflector assembly 401, such as Figure 1 , 2 As shown in , 6, and 7, the air deflector assembly 401 of the present solution includes an air deflector 420 and an air deflector block 430. The air deflector 420 includes an air deflector interface 421 and an air deflector body 422. The air deflector body 422 is a conical cylindrical structure. The inlet end of the air deflector body 422 is provided with an air deflector interface 421. The outer side of the end of the air deflector interface 421 is provided with an external thread. The outlet end of the air deflector body 422 is provided with a connecting ring edge. A plurality of air deflector threaded holes are provided along the circumferential direction of the connecting ring edge. The air deflector threaded holes are threadedly connected with the threaded holes on the edge of the pump-type reluctance motor end cover 110 through bolts. The air deflector body 422 with a conical cylindrical structure is conducive to increasing the flow velocity of the inlet fluid and promoting the fluid to enter the flow channel. The external thread on the outer side of the end of the air deflector interface 421 can form a threaded connection with the internal thread of the air deflector interface section 413. However, the connection method of the above two components is not limited to threaded connection, and can also be other connection methods that can achieve sealed connection.

[0039] The guide block 430 is a component used to adjust the flow state of the fluid inside the guide cover 420. Figure 2 , 7As shown in Figure 11, a guide block 430 is provided at the central part of the pump-type reluctance motor end cover 110 in the guide cover body 422 of the present solution. The guide block 430 is a cone structure. A plurality of guide grooves 431 extending in the axial direction are provided on the conical surface of the guide block 430 in the circumferential direction. A plurality of end cover inlets 111 are provided in the circumferential direction on the outer end cover of the central part of the pump-type reluctance motor end cover 110. A guide port 112 is provided on the inner edge of the end cover inlet 111. The guide grooves 431 and the guide port 112 are connected to guide the flow. The fluid entering the guide cover 420 flows into the end cover inlet 111 along the guide grooves 431 and the guide port 112 under the action of the guide block 430. This flow mode can avoid the formation of turbulence in the local area, resulting in a slowdown in the flow rate and energy loss. In addition, the arrangement position of the guide block 430 can also cover the bearing 341 of the rotating shaft 343, thereby protecting the bearing.

[0040] In order to improve the function of the pumped reluctance motor stator 200 and improve the stability of the assembly structure, such as Figure 8 As shown, the pumped reluctance motor stator 200 of the present solution further includes a stator end plate 220, which is arranged on the open end of the stator yoke 210. The stator end plate 220 includes an end plate yoke, and a plurality of end plate teeth 221 are arranged circumferentially on the inner side of the end plate yoke. A winding baffle 222 is arranged on the tooth top of the end plate teeth 221. The winding baffle 222 cooperates with the inner side of the end plate yoke to press and position the stator winding 212. The end plate yoke is an annular structure whose shape and size match the stator yoke 210. The end plate teeth 221 pass through the gap at the axial end of the stator winding 212 inwardly in the radial direction. The winding baffle 222 is arranged on the tooth top of the end plate teeth 221 extending out of the gap at the axial end of the stator winding 212. The stator winding 212 is clamped between the inner side of the end plate yoke and the winding baffle 222, thereby achieving the purpose of positioning and fixing the stator winding 212.

[0041] In order to improve the function of the pump-type reluctance motor rotor 300 and meet the requirements of easy assembly, disassembly and maintenance, the present solution also discloses an assembled rotor component. Figure 2 , 9 As shown in Figure 3, the rotor yoke 301 includes a rotor gear core 310 and a rotor tooth slot frame 320. The rotor gear core 310 includes a wheel core yoke. A plurality of rotor teeth 311 extending in the axial direction are circumferentially arranged on the outer side of the wheel core yoke. The rotor tooth slot frame 320 includes a gear core chassis 321. A plurality of wedge-shaped teeth 322 extending in the axial direction are circumferentially arranged on the edge of the gear core chassis 321. A wheel core yoke is arranged in the space surrounded by the wedge-shaped teeth 322 and the gear core chassis 321. Rotor teeth 311 are arranged between circumferentially adjacent wedge-shaped teeth 322. Circumferentially adjacent rotor teeth 311 and the wedge-shaped teeth 322 between the above-mentioned circumferentially adjacent rotor teeth 311 form a rotor flow channel 330. Fig. 9As shown, when the rotor gear core 310 is placed in the rotor tooth slot frame 320, the rotor teeth 311 extend from between the adjacent wedge-shaped teeth 322. Since the outer inclined surfaces of the wedge-shaped teeth 322 are inclined inward, the rotor flow channel 330 formed by the adjacent extended rotor teeth 311 and the wedge-shaped teeth 322 presents a semi-bell mouth state with a gradually expanding radial volume from upstream to downstream, as shown in FIG. Figure 4 As shown, when the fluid flows radially under the action of centrifugal force, the flow velocity gradually increases from upstream to downstream, and the pressure gradually decreases, and finally an axial flow force is formed between the upstream and downstream to drive the fluid to flow along the conveying direction. It should be noted that the method of forming the above-mentioned driving structure in this scheme is not limited to the split-type rotor gear core 310 and rotor tooth slot frame 320, and can also be other structures and structures that realize the above-mentioned functions, such as an integrated helical tooth structure, a spiral structure, an impeller-shaped structure, etc. At the same time, in order to achieve stable high-speed rotation, the pump-type reluctance motor rotor 300 also includes a rotating shaft 343, and bearings 341 are provided on both ends of the rotating shaft 343. The bearings 341 are positioned and installed on the end covers at both ends of the rotating shaft 343 through the bearing end covers 342.

[0042] In order to meet the installation requirements of internal components and improve the noise reduction performance and operation stability of the equipment, such as Figure 1 , 2 As shown in Figures 10 and 11, the pump-type reluctance motor housing 100 of the present solution includes a pump-type reluctance motor housing 120 and a pump-type reluctance motor end cover 110. A plurality of end cover internal thread holes are circumferentially arranged on the outer edge of the pump-type reluctance motor end cover 110, and a plurality of housing internal thread holes are circumferentially arranged on the end surface of the opening end of the pump-type reluctance motor housing 120. The end cover internal thread holes are threadedly connected with the corresponding housing internal thread holes by bolts. Based on the above solution, in order to achieve the flow diversion effect of the fluid outlet, as shown in Figures 10 and 11, a plurality of end cover internal thread holes are circumferentially arranged on the outer edge of the pump-type reluctance motor end cover 110, and a plurality of housing internal thread holes are circumferentially arranged on the end surface of the opening end of the pump-type reluctance motor housing 120. Fig.10 As shown, the outlet end of the pump-type reluctance motor housing 120 of the present solution is provided with an outlet-end flow guide baffle 121, and a plurality of fluid flow guide holes 122 are circumferentially provided on the peripheral baffle of the central mounting hole of the outlet-end flow guide baffle 121, and an axially extending installation positioning strip 123 is provided on the inner side of the pump-type reluctance motor housing 120, and the installation positioning strip 123 forms a positioning match with the installation positioning groove 214 on the outer side of the stator yoke 210. The introduction of the installation positioning strip 123 and the installation positioning groove 214 improves the stability of the stator during the operation of the equipment, avoids relative movement, and improves the working efficiency of the pump-type reluctance motor.

[0043] Furthermore, when the fluid flows in a direction through the rotor flow channel of the pump-type reluctance motor of the present invention, the pump-type reluctance motor rotor is driven to rotate under the action of the fluid, and the rotor teeth of the pump-type reluctance motor cut the magnetic field on the stator winding of the pump-type reluctance motor to form an induced current output, so that the pump-type reluctance motor has the function of a generator.

[0044] This scheme discloses a pump-type reluctance motor, which adopts an integrated design of a reluctance motor and a pump, wherein the rotor of the reluctance motor serves as the impeller of the pump, and the stator of the reluctance motor serves as the cavity of the pump. Combined with the characteristics of the rotor salient pole structure of the reluctance motor itself, as the rotor rotates, the gaps of the air gaps in different regions formed by the rotor teeth and the stator teeth in the pump-type reluctance motor change alternately, compressing or releasing the fluid in the stator, and realizing the function of extracting liquid and gas. Therefore, this scheme has the following characteristics: ⑴ It adopts an integrated design, compact structure, easy installation, and small overall volume; ⑵ It adopts a direct drive design, and the motor output torque is directly used for work, with less energy loss; ⑶ It adopts a lightweight design, simple structure, and low comprehensive cost; ⑷ It adopts a non-permanent magnet design, high temperature resistance, and long service life; ⑸ It adopts a streamlined design, overall sound insulation, and low operating noise; ⑹ The inlet and outlet are adjustable, the flow is controlled, and the thrust accuracy and stability are high. Experiments have shown that the pump-type reluctance motor can achieve high-efficiency, variable speed, and constant flow rate pumping functions, and the overall operation state is stable and silent. After experimental analysis and simulation calculations, the overall energy consumption is greatly reduced compared to traditional pumps, with an average energy saving of more than 20%. The pump-type reluctance motor disclosed in this solution can be applied to multiple fields, such as water pumps, oil pumps, air compressors, etc.

[0045] Unless otherwise specified, the structures, mechanisms, components, etc. disclosed in this solution can be implemented using common and conventional solutions known in the art. The pumped reluctance motor of this solution is not limited to the contents disclosed in the specific implementation methods. The technical solutions in the embodiments can be extended based on the understanding of those skilled in the art. Simple replacement solutions made by those skilled in the art based on this solution combined with common knowledge also fall within the scope of this solution.
