Description

Technical Field

[0001] The invention belongs to the technical field of motors and generators, and is used to improve the working efficiency of motors and generators, and in particular relates to a stator, a motor and a generator. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. Motors are divided into DC motors and AC motors according to the power source they use. Most motors in power systems are AC motors, which can be synchronous motors or single motors (the motor rotor and stator do not rotate at the same speed). A generator is a device that converts mechanical energy into electrical energy. It is installed in a power plant. Generators are divided into DC generators and AC generators according to the power source they use. Most generators in power systems are AC motors, and they are synchronous motors (the motor rotor and stator rotate at the same speed).

[0003] The stator of a motor or generator is the stationary part of the motor or generator. The stator consists of three parts: the stator core, the stator winding and the frame. The main function of the stator is to generate a rotating magnetic field, drive the rotor set inside the stator to rotate, and convert electrical energy into mechanical energy and mechanical energy into electrical energy. Most of the stators used in existing motors and generators are integrated or spliced. The spliced ​​stators can reduce production and processing costs and save punching scraps. However, since the spliced ​​materials are spliced ​​into a groove for every two, the insulated conductors on the stator cannot be spliced ​​together during the splicing process. In addition, when the insulated conductors are arranged in the grooves, there will be many more insulated conductors at both ends, resulting in high use costs. The inventors of this application document found in their research that setting the splicing pieces and the insulated conductors together can effectively reduce the use cost of the motor and generator stators. At the same time, changing the insulated conductors to conductive blocks can save costs while saving energy. For this reason, the inventors of this application have improved this structure. Summary of the invention

Implementation

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] The stator of the present invention, such as Figures 1 to 4 As shown, the stator includes a plurality of shells 1 and a plurality of conductive modules, and the plurality of conductive modules are installed on the plurality of shells 1 in a one-to-one manner. The plurality of shells 1 and the plurality of conductive modules are spliced ​​into a stator, that is, one or more conductive modules are installed on each shell 1. After the plurality of shells 1 and the plurality of conductive modules are spliced ​​into a stator, the conductive modules are electrically connected to each other, and a rotating magnetic field is generated after power is supplied, so as to directly form a complete stator, thereby saving punching scraps and reducing the production cost of the motor.

[0029] In the prior art, the stator cannot install the insulated conductor on a single splicing piece after the splicing is completed. Only after the stator is spliced, can the insulated conductor be installed on the stator, that is, the stator is spliced ​​into a stator frame, and then the insulated conductor is installed on the stator frame, which causes the problem of high stator manufacturing cost. The present application installs the conductive module on the stator splicing piece / shell 1. When the splicing piece / shell 1 is spliced ​​into the stator, the installation of the insulated conductor / conductive module on the stator is completed at the same time, thereby saving the stator manufacturing cost. In order to save the stator manufacturing cost, the shell 1 in this embodiment is set according to the circumferential angle and adopts the fan-shaped and one-piece molding setting, which can save the material cost to the greatest extent during the manufacturing process. That is to say, the stator is circular, and the shell 1 of this product adopts the circumferential angle setting. The precision of the stator after splicing is high, and the scraps can be reasonably used.

[0030] Two fan-shaped mounting holes 6 are processed on the shell 1, and the conductive modules are respectively installed in the two fan-shaped mounting holes 6. The outer contour of the conductive module matches the mounting holes 6 and is detachably arranged in the mounting holes 6. After the two conductive modules and a shell 1 are spliced ​​into a rotor, that is, before the stator is spliced, the conductive module and the shell 1 are combined. In this way, when the shell 1 is spliced ​​into the rotor, the conductive module on the shell 1 is electrically connected according to the motor wiring requirements to obtain a complete stator, thereby eliminating the step of installing the insulating conductor after the stator is spliced.

[0031] The shell 1 is made of silicon steel sheets, and the conductive module is insulated from the shell 1. There can be multiple mounting holes 6 on the shell 1, which can be set as needed. In this example, two are preferred. At the same time, the mounting holes 6 can be other shapes, such as round and square, etc., for the purpose of installing the conductive module. The mounting holes 6 in this embodiment are preferably fan rings, which are used to maximize and reasonably use the area on the shell 1.

[0032] Furthermore, the adjacent shells 1 among the plurality of shells 1 are detachably connected, and the detachable connection is convenient for later maintenance. When the conductive module on a certain shell 1 needs to be repaired, it is only necessary to extract the shell 1 from the stator and remove it together with the conductive module, and replace it with a new one or repair it, so as to avoid interference of other components with the maintenance. In order to realize the detachable connection of the shell 1, in this embodiment, connecting pieces are respectively arranged on both sides of the shell 1, and the adjacent shells 1 are detachably connected through the connecting pieces. The arrangement of the connecting pieces facilitates the staff to remove the shell 1 and the conductive film group arranged on the shell 1 from the stator. The connecting piece includes a connecting head 4 and a connecting slot 5 respectively arranged on both sides of the shell 1, and the connecting head 4 is connected to the connecting slot 5 on the adjacent shell 1, so that the adjacent shells 1 are detachably connected through the connecting head 4 and the connecting slot 5.

[0033] The connector 4 and the connection groove 5 are integrally formed. The connector 4 and the connection groove 5 are arranged on the shell 1 while the shell 1 is being manufactured. That is to say, the shell 1, the connector 4 and the connection groove 5 can be stamped together by stamping, which is convenient for the staff to manufacture the shell 1 and can also save a lot of manufacturing processes. The connector 4 and the connection groove 5 can adopt a variety of shapes to complete the detachable connection between adjacent shells 1, such as circular, rectangular, etc., in order to detachably connect adjacent shells 1. The specific shape can be set according to the needs, that is, the shape of the intersection between two adjacent shells 1 can be set without restriction; when a circle is adopted: one of the adjacent shells 1 uses a convex circle and the other uses a concave circle; when a rectangle is adopted: one of the adjacent shells 1 uses a convex rectangle and the other uses a concave rectangle.

[0034] Further, such as Figure 1 As shown, a conductive film group is arranged on the shell 1 to splice into a stator. The spliced ​​stator can be fixedly connected or detachably connected. The fixed connection and detachable connection here are arranged according to environmental requirements. That is to say, the spliced ​​stator of the shell 1 can be fixedly connected by welding or detachably connected by connecting parts. In this embodiment, a detachable connection is preferred.

[0035] The conductive module in this embodiment, such as Figures 4 to 6 As shown, the conductive module includes a conductive block 2, the outer contour of the conductive block 2 matches the mounting through hole 6, the conductive block 2 adopts a copper block, and conductive columns 3 are respectively arranged at the upper and lower ends of the copper block, and the conductive columns 3 are electrically connected to the adjacent conductive blocks 2 or an external power supply, and are used to supply power to the conductive block 2 so that the conductive block 2 generates a magnetic field when powered on, thereby driving the rotor set in the stator to rotate. The conductive block 2 here can adopt a variety of shapes, and its shape can match the above-mentioned mounting through hole 6, that is to say, the conductive block 2 is not restricted by the shape. At the same time, the conductive block 2 can also be made of other materials, and those materials that can generate a magnetic field after power is supplied can be used. According to the working principle of the motor, it is only necessary to generate a magnetic field on the stator, and the rotor set inside the stator can be driven to rotate in cooperation with the rotor magnetic field.

[0036] In the prior art, many coils will emerge from the two ends of the stator. The conductive block 2 of this product is parallel to the two ends of the stator. The conductive block 2 is connected to the external power supply through the conductive column 3. The arrangement of the conductive block 2 can save the coils emerging from the two ends of the stator, and the coils at the two ends are replaced by the conductive column 3. That is to say, the coils emerging from the two ends of the stator are the coils in each groove connected in series. Compared with the single conductive column 3, the coils emerging from the two ends use significantly less copper material, thereby achieving the purpose of saving copper.

[0037] Further, such as Figure 6As shown, the conductive block 2 is preferably a hollow conductive block. According to the skin effect, the current passes through the surface of the conductor. The use of the hollow conductive block 2 can effectively save copper material, that is, the solid copper block is changed to a hollow copper block, so as to achieve the purpose of saving copper; according to the working principle of the motor, the more the motor power is, the more electrical energy is input; this product uses a hollow copper block, which can save most of the coils on the stator, that is, the coils at both ends of the stator. The required current will also be reduced due to the saving of copper coils, thereby achieving the purpose of saving electricity.

[0038] Furthermore, the conductive module may also use an insulated conductor, and the insulated conductor is wound on the shell 1 according to a predetermined number of turns in cooperation with the silicon steel sheet shell 1, that is, it is wound on the shell 1 between the intersection of the two mounting through holes 6, and at the same time, some turns of the insulated conductor are located in the two mounting through holes 6. After power is turned on, a magnetic field is generated to drive the rotor to rotate. That is to say, the stator in this embodiment can use not only the conductive block 2 but also the insulated conductor. According to the electromagnetic principle, inserting an iron piece in the middle of the coil can enhance the magnetic field of the coil, which is beneficial to enhance the magnetic field on the stator.

[0039] Further, such as Figure 2 , Figure 5 As shown, the conductive module also includes an excitation magnetic field, which is a permanent magnet. The outer contour of the permanent magnet matches the mounting through hole 6. The permanent magnets are distributed on the stator in a certain number, that is, distributed on the stator at a certain symmetrical angle. In this way, the magnetic field generated by the insulating conductor or the hollow conductive block 2 is superimposed on the magnetic field of the permanent magnet. After satisfying the magnetic energy required to generate a magnetic field on the stator to do work, the number of conductive blocks 2 and / or insulated conductors can be reduced. That is, when the magnetic field on the stator can meet the preset value of the motor, then as the number of insulating conductors or hollow conductive blocks 2 decreases, the current used will also decrease, thereby once again achieving power saving.

[0040] The electrical connection cover plate in this embodiment is as follows: Figure 7-8As shown, the purpose of setting the electrical connection cover is to complete the electrical connection between the conductive blocks 2 on the stator. At the same time, the arrangement of the electrical connection cover and the coordination between the conductive pillars 3 can save the coils protruding from both ends of the stator. The prior art uses the coils protruding from both ends of the stator to complete the electrical connection between the coils in the stator grooves. The existence of this part of the coil is to complete the electrical connection between the insulated conductors in the grooves. The use of the conductive blocks 2, the conductive pillars 3 and the electrical connection cover can save the coils protruding from both ends of the stator. In order to save the coils emerging from both ends of the stator, this product adopts the method of conductive block 2 plus electrical connection cover plate, the electrical connection cover plate includes upper electrical connection cover plate 8 and lower electrical connection cover plate 7, the upper electrical connection cover plate 8 and lower electrical connection cover plate 7 are respectively located at both ends of the stator, and mounting holes are respectively provided on the upper electrical connection cover plate 8 and the lower electrical connection cover plate 7, and connecting cylinders matching with the conductive column 3 are provided in the mounting holes, and circuits are provided inside the upper electrical connection cover plate 8 and the lower electrical connection cover plate 7, and the circuits are connected to the connecting cylinders, and the conductive column 3 is plugged into the connecting cylinders, wherein the circuits are arranged according to the layout of the motor magnetic field, and specific reference is made to Chinese patent: 20231033 9002.2, a motor terminal, wherein a conductive column 3 is also provided on the upper electrical connection cover plate 8, one end of the conductive column 3 is connected to the circuit in the upper electrical connection cover plate 8, and the other end is connected to the external power supply, that is, the external power supply transmits the current to the upper electrical connection cover plate 8 through the conductive column 3, and inputs the current to the lower electrical connection cover plate 7 through the conductive block 2, and the lower electrical connection cover plate 7 completes the series connection between the conductive blocks 2, so that the conductive blocks 2 generate a magnetic field after being energized. The principle is referenced to https: / / www.docin.com / p-324494312.html, so as to achieve the purpose of saving copper.

[0041] Furthermore, the electrical connection cover plate adopts an insulating cover plate to avoid short circuit. The electrical connection cover plate replaces the traditional direct contact, and the conductive column 3 replaces the coils emerging from both ends of the stator, thereby saving the coils emerging from both ends of the stator. The connection between the conductive block 2 and the power supply is completed by plugging, which is convenient for later maintenance. That is, after removing the electrical connection cover plate, a housing 1 and a conductive module on the stator can be removed. In the prior art, the insulating conductors are welded, which is extremely inconvenient to remove.

[0042] Furthermore, holes are respectively provided at the center positions of the upper electrical connection cover plate 8 and the lower electrical connection cover plate 7, and the sizes of the holes are respectively the same as the sizes of the center holes on the stator after the splicing is completed, that is, the inner and outer edges of the upper electrical connection cover plate 8 and the lower electrical connection cover plate 7 are respectively equal to the inner and outer edges of the stator, so as to complete the electrical connection between the conductive blocks 2 on the stator without affecting the installation of other components and maintaining the coordination with the stator.

[0043] Furthermore, the selling point of this product is to change the electrical connection method between the conductive blocks on the stator 1, from the initial direct connection method to a plug-in connection. The purpose of setting the lower electrical connection cover plate 7 is to complete the series layout of the electrical connection between the lower ends of the hollow conductive blocks 2 inside the stator. The purpose of the upper electrical connection cover plate 8 is to complete the series layout of the electrical connection between the upper ends of the conductive blocks 2 inside the stator, and complete the electrical connection between the hollow conductive blocks 2 and the outside world. The upper electrical connection cover plate 8 is also provided with a conductive column 3 connected to the power supply. The conductive column 3 connects the power supply to the stator. The conductive block 2 generates a magnetic field under the action of the current to drive the rotor to rotate. The electrical connection layout and the electrical connection method between the conductive blocks 2 can be referred to Chinese Patent: 202320272214.9, a new type of motor. Since the electrical connection layout between the motor coils is a prior art, it is not elaborated here.

[0044] The cover plate in this embodiment, such as Figures 9 to 12 As shown, the cover plate is used to strengthen the stator. In the prior art, the spliced ​​stator is directly installed in the casing. It is easy to have a loose connection during the operation of the motor. In particular, the vibration force generated by the motor during operation will cause the connection between the spliced ​​stators to loosen and misalign. In this embodiment, cover plates are respectively arranged at the upper and lower ends of the stator. The cover plates are installed on the stator after the splicing is completed to avoid the loosening of the spliced ​​parts / casing 1 caused by vibration. In order to improve the firmness of the stator after splicing, the cover plates used in this product include an upper cover plate 9 and a lower cover plate 10. The center positions of the upper cover plate 9 and the lower cover plate 10 are respectively provided with center plates matching the stator. Hole, that is, through hole for installing the rotor, flanges are respectively arranged on the outer edges of the upper cover plate 9 and the lower cover plate 10, wherein the upper cover plate 9 is provided with a through hole, and the conductive column 3 located on the upper electrical connection cover plate 8 can pass through the through hole and be electrically connected to the outside through a wire, and the upper cover plate 9 and the lower cover plate 10 are installed at both ends of the stator, and the inner wall of the flange contacts the outer wall of the stator, and at the same time, the lower parts of the flanges located on the upper cover plate 9 and the lower cover plate 10 contact each other, so that the stator can be firmly fixed, that is, the upper cover plate 9, the lower cover plate 10 and the flange completely wrap the stator to improve the firmness of the stator, and at the same time, it is installed in the casing to avoid vibration causing the casing 1 to loosen. The flange and the upper cover plate 9 and the lower cover plate 10 are formed in one piece of metal parts to improve the firmness of the stator after splicing and avoid dislocation and looseness.

[0045] Further, such as Figures 13-15 As shown, the height of the flanges on the upper cover plate 9 and the lower cover plate 10 is smaller than the height of the flanges in the above-mentioned embodiment, that is, the lower parts of the flanges on the upper cover plate 9 and the lower cover plate 10 do not contact each other, which can also achieve reinforcement of the spliced ​​stator and is also beneficial to heat dissipation. That is to say, when the upper and lower flanges do not contact, the heat generated by the conductive film group on the shell 1 is more easily dissipated.

[0046] Furthermore, there are no flanges on the upper cover plate 9 and the lower cover plate 10. The upper cover plate 9 and the lower cover plate 10 without flanges can also be used to strengthen the stator. The assembled stator is installed in the casing, and then the upper cover plate 9 and the lower cover plate 10 are respectively placed in the casing and located close to the two ends of the stator. The upper cover plate 9, the lower cover plate 10 and the stator are fixed to the casing by bolts and other components to achieve the purpose of strengthening the stator. Therefore, there are many ways to strengthen the stator in this embodiment, and it is preferably achieved by adding flanges to the upper cover plate 9 and the lower cover plate 10.

[0047] In summary, two mounting through holes 6 are provided on the shell 1, and hollow conductive blocks 2 or permanent magnets are installed in the two mounting through holes 6. The hollow conductive blocks 2 are insulated from the shell 1, and the hollow conductive blocks 2 and permanent magnets located in the two mounting through holes 6 are installed as follows: a. Two hollow conductive blocks 3 are installed in the two mounting through holes 6 at the same time; b. One hollow conductive block 3 and a permanent magnet are installed in the two mounting through holes 6; c. Two permanent magnets are installed in the two mounting through holes 6 at the same time; the hollow conductive blocks 3 are powered to generate a magnetic field, and the magnetic field of the permanent magnet is superimposed on each other to enhance the magnetic field on the stator of the motor, thereby improving the work efficiency of the motor.

[0048] Specifically: the casing and rotor required for use in this embodiment are both rotors and casings in the prior art, wherein the rotor is a squirrel cage motor rotor, and the magnetic field on the rotor can be set vertically or obliquely to realize the operation of the motor, preferably set obliquely, which is beneficial to reduce the vibration generated by the operation of the motor; when in use: the stator is installed in the casing, and the rotor is installed in the stator to form a motor, and the hollow conductive block 2 and the permanent magnet on the stator are inserted into the mounting through hole 6 on the stator upper shell 1 to complete the assembly of the stator, and the hollow conductive block 2 and the permanent magnet are inserted into the mounting through hole 6 on the shell 1, and then spliced ​​into a stator, which greatly shortens the production process of the motor stator and saves manpower and financial resources; during the maintenance process, only the hollow conductive block 2 needs to be replaced, and the coil in the prior art is not convenient to be removed from the groove; this product adopts the hollow conductive block 2 for easy maintenance, and the hollow conductive block 3 and the permanent magnet are set on the stator, which can save copper materials while meeting the work of the motor.

[0049] Furthermore, the electrical connection between the hollow conductive blocks 2 on the stator is as follows: there are 24 mounting through holes 6 on the stator after the splicing is completed, and the hollow conductive blocks 2 are respectively installed in the 24 mounting through holes 6, wherein the electrical connection of the hollow conductive blocks 2 is connected in the manner of a, b, and c, and in series in the manner of a1, b1, and c1, a and a1 are four series and two leads are connected to the power supply, b and b1 are four series and two leads are connected to the power supply, and c and c1 are four series and two leads are connected to the power supply, that is, there are three magnetic fields on the stator for driving the rotor, and a Hall sensor is used to detect the change of the magnetic field on the rotor, and the sequence of the current input to the hollow conductive blocks 2 on the stator is changed, thereby controlling the hollow conductive blocks 2 to generate a magnetic field, thereby driving the rotor set on the stator to rotate to complete the work of the motor.

[0050] Furthermore, before the shell 1 is spliced, the conductive film group is set in the installation hole 6 according to the preset motor power, and then the shell 1 is spliced ​​into a stator. The conductive film group on the stator is electrically connected according to the above-mentioned methods a, b, and c. In other words, it is possible to first assemble the stator and then install the conductive film group, and it is also possible to install the conductive film group on the shell 1 to splice it into a stator.

[0051] Furthermore, the cooperation between the hollow conductive block 2 and the permanent magnet on the stator and the electrical connection between the hollow conductive blocks 2 are as follows: there are 24 mounting through holes 6 in this embodiment, and a hollow conductive block 2 and a permanent magnet are respectively installed in each mounting through hole 6, and the permanent magnet and the hollow conductive block 2 are arranged at intervals of every two, wherein the electrical connection of the hollow conductive block 2 is realized according to the above-mentioned methods a, b, and c, and the permanent magnet 4 is arranged at intervals from the hollow conductive block 2. There are three magnetic fields on the stator for driving the rotor, and a Hall sensor is used to detect the change of the magnetic field on the rotor, and the sequence of the current input to the hollow conductive block 2 on the stator is changed, thereby controlling the hollow conductive block 2 to generate a magnetic field, so as to complete the sector transition of the rotor in this area and drive the rotor to rotate inside the stator, wherein the magnetic field of the permanent magnet arranged adjacent to the hollow conductive block 2 and the magnetic field generated by the hollow conductive block 2 are superimposed on each other, and the superimposed magnetic field will enhance the magnetic field on the stator, and the enhancement of the magnetic field is conducive to improving the work efficiency of the motor, and as the number of hollow conductive blocks 2 decreases, the input current will also decrease, thereby achieving the purpose of saving electricity.

[0052] The motor provided in this embodiment is as follows: Figures 1 to 15As shown, the stator 1 and the conductive module installed on the stator 1 are combined with the rotor in the prior art to form a motor, and the motor is compared with the motor in the prior art; the motor of this product is compared with the existing motor YBPT (355~560), 37KW motor data; the starting current of the YBPT (355~560), 37KW motor is about 250A, the working current under load is about 70A, and it consumes about 37 kWh of electricity in one hour; the starting current of the motor of this product is about 200A, the working current under load is about 50A, and it consumes about 30 kWh of electricity in one hour. The data is obtained through actual detection of the electric meter. The motor of this product is compared with the YBPT (355~560) 37KW motor working in the same environment: The motor of this product can save about 10 kWh of electricity per hour compared with the existing YBPT (355~560) 37KW motor, that is to say, it can save 10 kWh of electricity per hour; comparison of copper usage data: YBPT (355~560) 37KW uses about 37 kg of copper; the new motor stator of this product is about 25 kg, and the copper usage data is obtained by weighing on an electronic scale; that is to say, the new motor stator of this product and YBPT (355~560) 37KW motor can save 12 kg of copper each. Since there are many copper wires on both ends of the YBPT (355~560) 37KW motor stator, this product just saves this part of the coil, and at the same time, with the cooperation of the permanent magnet, it achieves the purpose of saving copper and electricity.

[0053] The generator provided in this embodiment is as follows: Figures 1 to 15 As shown, the stator and the conductive module are combined with the rotor in the prior art to form a generator; the stator of the generator is the stationary part of the motor, and the components mainly include the iron core, the frame, the insulating conductor or the hollow conductive block 2. The conductive module on the stator and the hollow conductive block 2 replace the coil in the prior art, and the hollow conductive block 2 is the main core component of the generator. The stator core is the main magnetic circuit of the stator, and is also the installation and fixing component of the stator winding; the stator core is composed of fan-shaped through holes, tightening bolts, support blocks, positioning ribs and other components; the iron core is part of the generator magnetic circuit; the conductive module forms the circuit of the generator, and the stator winding of the generator uses the conductive module, that is, the hollow conductive block 2, to generate current output and achieve the purpose of power generation; based on the above understanding, the structure between the motor and the generator is the same, and the working principle of the generator is based on the law of electromagnetic induction and the law of electromagnetic force; therefore, the principle of its construction is: using appropriate magnetic and conductive materials to form a magnetic circuit and circuit for mutual electromagnetic induction to generate electromagnetic power and achieve the purpose of energy conversion, so the stator of this product is installed on the generator, which can improve the work efficiency of the generator.

[0054] Further, the generator of this product is compared with the generator in the prior art; the generator provided by this product saves manpower and financial resources in the production process, especially in the process of generator assembly, the production process of the generator is reduced, and manpower and financial resources are indirectly saved; generator efficiency data comparison: the generator of this product is compared with the data of the existing generator model SF-55-55KW; when the generator power is the same, the comparison is made: this product saves about 10 kilograms of copper, mainly by eliminating the copper wires protruding from both ends of the stator; the generator in the prior art requires about 35 kilograms of copper, that is, the generator of this product uses 25 kilograms of copper, refer to the following Table 1 for the generator parameters in the prior art: Since many copper wires will emerge from both ends of the stator used by the existing generator model SF-55-55KW, many copper wires will not emerge from both ends of the stator provided by this product, but will be replaced by conductive columns 3 and electrical connection covers, thereby achieving the purpose of saving copper; the stator is installed on the generator, and the rotor is installed inside the stator. Since the stator is improved and installed on the generator, the work efficiency of the generator can be improved and the purpose of saving copper can be achieved; Table 1.
