[0003] The insulating conductor used in the above-mentioned hollow motor stator is wound on the stator, that is, a groove is set on the outer edge of the stator, and then the insulating conductor is arranged in the groove, and the electrical connection between adjacent insulating conductors is completed through the extra insulating conductors and leads at both ends, wherein the insulating conductor adopts a coil and is wound in the groove of the stator and fixed by insulating paint treatment. With the long-term use of the motor, the coil set in the stator groove will age or other factors will cause the coil to be damaged. In the process of replacing the coil, it is necessary to remove the damaged coil from the stator groove and arrange a new coil. Since the coils in each groove are staggered and arranged in series, that is, the adjacent coils are arranged at intervals, which is inconvenient to remove and replace, and the stator is easily damaged during the process of disassembling the coil; the inventor of this application document found in the research that replacing the above-mentioned insulating conductor with a conductive block can effectively save the extra copper wire at both ends of the stator, and it is also convenient for the staff to assemble and disassemble; adding magnets to the coils can easily increase the magnetic field inside the motor stator, thereby improving the work efficiency of the motor.

DETAILED DESCRIPTION

[0023] 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.

[0024] For the technology in this embodiment, please refer to the Chinese patent applications with application numbers: 202310144502.0, 202310339002.2, and 202310401139.6 and application name “An energy-saving motor, a motor terminal, a motor stator power supply method, device, and controller”. Part of the content is combined by reference in this application to understand this product. The purpose of referring to the above technical documents is to understand the electrical connection and working principle between the conductive modules.

[0025] The hollow motor is a common motor, and its working principle is realized through the principle of electromagnetic induction. Its structure consists of a magnetic core, an armature and an armature winding. There is a group of magnets on the magnetic core, and a group of windings on the armature. When current passes through the armature winding, the magnets on the magnetic core will generate a magnetic field, and the armature winding will also generate a magnetic field. These fields will interact with each other and generate force from the surface: the electrode cable group will rotate, thereby realizing the rotation of the motor. The hollow motor is a common motor, and its working principle is realized through the principle of electromagnetic induction. It has the advantages of simple structure, small size, high power, high efficiency and high reliability.

[0026] Simply put: the fixed part of the motor is called the stator, on which pairs of DC-excited static main magnetic poles are installed; and the rotating part, the rotor, is called the armature core, on which the armature winding is installed. When powered on, it generates induced electromotive force, acts as a rotating magnetic field, and then generates electromagnetic torque for energy conversion.

[0027] The hollow motor provided in this embodiment is used for: a rotating platform and turntable: the hollow motor can be used for a rotating platform, turntable or rotating display stand, allowing rotational motion without interfering with the internal passage of the motor, such as in exhibitions, billboards, photographic equipment, etc. b medical imaging equipment: the hollow motor is suitable for medical equipment, such as CT scanners, X-ray machines, etc., to transmit cables, cooling liquids and other signals through the central passage to achieve rotational motion without interfering with internal imaging. c semiconductor production equipment: in semiconductor manufacturing, hollow motors can be used in semiconductor cutting, coating, testing and other equipment, and cables, gas or vacuum signals are transmitted through the hollow structure to enable the equipment to rotate or move. d automated assembly line: on an automated production line, a hollow motor can be used to transmit cables, gas or cooling liquid, so that a robot arm or tool can remain connected during rotation. The unique design and function of the hollow motor make it very useful in applications that require simultaneous motion and signal transmission. These application scenarios usually require precise motion control and signal transmission. Hollow motors can meet these requirements and provide a high degree of flexibility.

[0028] like Figures 3-5 As shown, the stator of the hollow motor, the stator 2 includes an annular component 2-1, and the annular component 2-1 is provided with stator mounting through holes 2-5, and the stator mounting through holes 2-5 are evenly distributed around the axis of the annular component 2-1; a conductive module is installed in the stator mounting through hole 2-5, and the conductive module matches the stator mounting through hole 2-5 and is detachably arranged in the stator mounting through hole 2-5; the conductive module replaces the insulated conductor in the prior art, where the insulated conductor is a coil of turns or a flat wire, which reduces the process and steps of winding the coil on the stator 3, saves the motor manufacturing process, and the conductive module also saves the extra coils at both ends of the stator 2, thereby saving costs and facilitating assembly and subsequent maintenance by the staff.

[0029] The annular component 2-1 is formed by stacking annular silicon steel sheets, and the stator mounting through hole 2-5 is a fan ring. The stator mounting through hole 2-5 is processed on the annular silicon steel sheet while manufacturing the single-layer annular component 2-1. The stator mounting through hole 2-5 is set as a fan ring to reasonably use the spatial area on the annular component 2-1, that is, to reasonably use the area on the annular component 2-1 in the form of a fan ring to avoid waste or incomplete use of the area; since the stator mounting through hole 2-5 on the stator 2 is set at a circular angle, the stator mounting through hole 2-5 processed on the annular component 2-1 selects a fan ring structure, which can effectively and reasonably use the spatial area on the annular component 2-1.

[0030] like Figures 11 to 13As shown, the conductive module includes a conductive medium, which is installed in the stator mounting through hole 2-5 mentioned above. The outer contour of the conductive medium matches the stator mounting through hole 2-5 and is detachably arranged and insulated. The conductive medium is made of conductive medium materials, that is, materials that can input current to generate a magnetic field. Different conductive medium materials can be set according to the work needs of the motor. The conductive medium material here is preferably a conductive block 2-4, that is, a copper block. The copper block is a hollow copper block. The hollow copper block can effectively save copper materials according to the principle of skin effect.

[0031] like Fig.13 As shown, the conductive module also includes an excitation magnetic field, which is also installed in the stator mounting through hole 2-5 mentioned above. The outer contour of the excitation magnetic field matches the stator mounting through hole 2-5 and is detachably arranged in the stator mounting through hole 2-5. The excitation magnetic field is a permanent magnet. The permanent magnet is spaced apart from the hollow copper block mentioned above. The magnetic field generated by the input current of the hollow copper block and the magnetic field of the permanent magnet are superimposed on each other to enhance the magnetic field on the stator 2, which is beneficial to improving the work efficiency of the hollow motor. As the number of permanent magnets in the stator mounting through hole 2-5 increases, the number of hollow copper blocks used will decrease, and the current input will also decrease as the number of hollow copper blocks decreases. Since the magnetic field generated by the permanent magnet and the magnetic field generated by the hollow copper block are superimposed on each other, the generated magnetic field can save electricity while satisfying the work of the hollow motor.

[0032] like Figures 2~5 -11~13, the stator 2 is provided with a stator mounting through hole 2-5, and a conductive module is arranged in the stator mounting through hole 2-5. The conductive module includes a conductive block 2-4 and a permanent magnet. The layout of the conductive block 2-4 and the permanent magnet on the stator is as follows: a. The conductive block 2-4 is installed in the stator mounting through hole 2-5, and conductive columns 2-3 are respectively arranged at both ends of the conductive block 2-4. The conductive columns 2-3 are connected in series with each other through leads, thereby completing the electrical series connection between the conductive blocks 2-4 and completing the electrical connection with an external power supply; b. The conductive block 2-4 and the permanent magnet are installed in the stator mounting through hole 2-5, and the permanent magnet and the conductive block 2-4 are arranged at intervals. The conductive columns 2-3 are connected in series with each other through leads, thereby completing the electrical series connection between the conductive blocks 2-4 and completing the electrical connection with an external power supply. Such a design facilitates the control of the power of the hollow motor, that is, controlling the work done by the hollow motor, which is achieved by the layout of the conductive block 2-4 and the permanent magnet on the stator 2.

[0033] like Figure 4As shown, a conductive block 2-4 or a permanent magnet is installed in the stator mounting through hole 2-5 according to the needs of the hollow motor, wherein the electrical connection method between the conductive blocks 2-4 is the prior art, that is, the series connection method of the insulated conductors on the motor stator in the prior art, the purpose is to complete the power supply to the insulated conductors in the stator groove or the conductive block 2-4 in the stator mounting through hole 2-5. Refer to the following website for easy understanding: https: / / www.docin.com / p-324494312.html.

[0034] Furthermore, the conductive blocks 2-4 and permanent magnets mentioned above can be obliquely arranged in the stator mounting through holes 2-5, that is, the stator mounting through holes 2-5 on the stator 2 can be obliquely arranged, and the current and voltage used by the obliquely arranged hollow conductive blocks 2-4 are relatively stable. The obliquely arranged hollow conductive blocks 2-4 make the current a sine wave, thereby reducing the harmonics generated when the hollow motor is working and improving the work efficiency of the motor, that is, reducing the vibration force generated when the hollow motor is working; please refer to 202321984589.4, a stator, a motor, a generator, and the technology provided.

[0035] like Figure 3 , Figure 6 As shown, the stator 2 is also provided with an annular electrical connection cover plate 2-2, which is installed at both ends of the stator 2. A plurality of cylindrical electrical connectors are provided on the annular electrical connection cover plate 2-2, and the plurality of cylindrical electrical connectors are evenly distributed around the axis of the annular electrical connection cover plate 2-2. One end of the cylindrical electrical connector extends into the annular electrical connection cover plate 2-2, and the other end is parallel to the surface of the annular electrical connection cover plate 2-2. A connecting wire is provided inside the annular electrical connection cover plate 2-2, and the connecting wire completes the electrical connection between the cylindrical electrical connectors provided on the annular electrical connection cover plate 2-2. The conductive column 2-3 on the conductive block 2-4 is inserted into the cylindrical electrical connector to complete the electrical connection between the conductive block 2-4 and the outside world. Since the coil at the end does not help the full-disk motor power and only serves as a connection, which will generate additional electrical loss, the shorter the better. Therefore, the annular electrical connection cover plate 2-2 provided in this embodiment completes the electrical connection between the conductive blocks 2-4, thereby saving the extra coils at both ends of the stator 2.

[0036] Further, such as Figure 6 As shown, a conductive column 2-3 is also provided on the annular electrical connection cover plate 2-2 located on the upper part of the stator 2. One end of the conductive column 2-3 extends into the annular electrical connection cover plate 2-2 and is electrically connected to the connecting line, and the other end is connected to an external power supply. This arrangement facilitates electrical connection with the outside world and also saves extra coils at both ends of the stator.

[0037] Furthermore, in the prior art, there are many extra coils at both ends of the stator. This product uses a conductive block 2-4 and an annular electrical connection cover 2-2 to effectively save the coils protruding from both ends of the stator 2, that is, the conductive column 2-3, the conductive block 2-4 and the annular electrical connection cover 2-2 cooperate to complete the electrical connection between the conductive block 2-4 and the outside world, thereby saving copper wires. The prior art completes the connection through the extra coils at both ends, which will waste a lot of copper wires.

[0038] like Figures 7-9 As shown, it includes a rotor 1, which adopts a hollow ring. The hollow ring is provided with rotor mounting holes 1-4, and the rotor mounting holes 1-4 are evenly distributed around the axis of the rotor 1. The rotor mounting holes 1-4 are installed with magnetic poles 1-3, and the magnetic poles 1-3 are installed in the rotor mounting holes 1-4 to improve the firmness of the magnetic poles 1-3 and the rotor 1. Here, the rotor 1\hollow ring is also made of stacked silicon steel sheets.

[0039] like Fig.13 As shown, further, the magnetic poles 1-3 are permanent magnets, and the permanent magnet layout here is the same as the magnetic field layout of the hollow motor in the prior art. When in use, the conductive blocks 2-4 on the stator 2 are powered and generate a rotating magnetic field. The rotating magnetic field drives the magnetic poles 1-3 set on the rotor 1 to complete the sector transition on the conductive blocks 2-4 of the stator 2, thereby completing the rotation of the rotor 1 in the stator 2; the working principle can be referred to: disc type, full disc motor - Baidu Library (baidu.com).

[0040] Furthermore, a cover plate 1-2 is provided on the rotor 1. The cover plate 1-2 is a hollow ring. The cover plate 1-2 is provided at both ends of the rotor 1 and is used to fix the magnetic pole 1-3 to facilitate the subsequent installation of other components.

[0041] Further, such as Fig.11As shown, the conductive blocks 2-4 are arranged in the stator mounting through holes 2-5 according to the power requirements of the hollow motor, that is, the number of the conductive blocks 2-4 is set according to the requirements. There are 48 stator mounting through holes 2-5 arranged on the stator 2, and it is only necessary to install the required number of conductive blocks 2-4 in the 48 stator mounting through holes 2-5 according to the full-disk motor power requirements. For example, 24 conductive blocks 2-4 are installed, with an additional stator mounting through hole 2-5 between each adjacent conductive block 2-4, and nothing is installed in the additional stator mounting through hole 2-5. In this way, the 24 conductive blocks 2-4 can meet the work of the hollow motor, and the purpose is to adjust the power of the hollow motor. At the same time, 48 conductive blocks 2-4 can be installed as needed, and only 24 of them need to be powered to meet the work of the hollow motor, that is, according to the power requirement of the hollow motor, 24 of the 48 conductive blocks 2-4 are powered to meet the power of the hollow motor. When the power of the hollow motor is increased, it is only necessary to install and power the 48 conductive blocks 3-2 in sequence to increase the power of the hollow motor, which is convenient for controlling and adjusting the power of the hollow motor.

[0042] Further, such as Figure 4 As shown, the stator mounting through holes 2-5 arranged on the stator 2 can be multiple, such as: 96 or 24 and more and less, that is, the stator mounting through holes 2-5 on the stator 2 of the hollow motor can be appropriately set according to needs, and the method of installing the conductive module and the power supply method are the same as the above principles, which will not be elaborated here. The purpose is to set it according to the use method, environment and power size of the hollow motor, and to install the number of conductive blocks 2-4 used or the power supply number according to the power size of the hollow motor, so as to realize the reasonable use of the power size of the hollow motor.

[0043] Further, such as Figure 4 As shown, the installation method of the conductive block 2-4 and the permanent magnet arranged in the stator mounting through hole 2-5 is as follows: a. Install a hollow conductive block 2-4 in the stator mounting through hole 2-5; b. Install a conductive block 2-4 and a permanent magnet in the stator mounting through hole 2-5, and the conductive block 2-4 and the permanent magnet are arranged alternately. The magnetic field generated by supplying power to the conductive block 2-4 is superimposed with the magnetic field of the permanent magnet to enhance the magnetic field on the stator 2 of the hollow motor, thereby improving the work efficiency of the hollow motor. That is, the number of conductive blocks 2-4 and permanent magnets arranged on the stator 2 of the hollow motor can be set as needed, and is not limited to the above-mentioned limitations, and can realize power control of the hollow motor. Such an arrangement enables different powers to be used in full-disk motors of the same size.

[0044] Furthermore, the electrical connection between the conductive blocks 2-4 on the stator 2 is as follows: there are 48 stator mounting through holes 2-5 on the stator 2, that is, there are 48 conductive blocks 2-4 on the stator 2, which can be electrically connected in the manner of a, b, c, a1, b1, c1, a2, b2, c2, a3, b3, c3, a, a1, a2, a3 are four series connected, and four leads are led out to connect to the power supply, b, b1, b2, b3 are four series connected, and four leads are led out to connect to the power supply, c, c1, c2, c3 are four series connected, and four leads are led out to connect to the power supply, that is, there are four magnetic fields on the stator 2 for driving the rotor 1, and a Hall sensor is used to detect the magnetic field change position of the magnetic poles 1-3 on the rotor 1, and the signal is input into the motor controller, and the motor controller changes the sequence of current input to the conductive blocks 2-4 on the stator 2, thereby controlling the conductive blocks 2-4 to generate a magnetic field to drive the rotor to rotate.

[0045] like Figure 1~2 As shown, a hollow motor is realized by combining the stator 2 and the rotor 1 mentioned above; the rotor 1 is installed inside the stator 2, and is assembled into a hollow motor through components that can be purchased on the market. Here, the components required for the hollow motor are all purchased by the motor controller on the market; the conductive blocks 2-4 on the stator 2 are powered, and the conductive blocks 2-4 complete the power supply in a certain order, and the magnetic field generated drives the magnetic poles 1-3 on the rotor 1 to complete the sector transition on the stator 2, and the rotor 1 is driven to rotate inside the stator 3 as the power supply sequence of the conductive blocks 2-4 changes.

[0046] Furthermore, there are 48 conductive blocks 2-4 on the stator 2, and 48 or 24 magnetic poles 1-3 on the rotor 1. The sensor detects the position change of the magnetic poles 1-3 on the rotor 1 and transmits the signal to the motor controller. The motor controller supplies power to the conductive blocks 2-4 on the stator 2 in sequence. The conductive blocks 2-4 correspond to the changes of the magnetic poles 1-3 on the rotor 1 and drive the magnetic poles 1-3 to complete the sector transition on the conductive blocks 2-4. In other words, the number of magnetic poles 1-3 on the rotor 1 can be set according to the work requirements of the hollow motor.

[0047] Furthermore, the number of conductive blocks 2-4 on the stator 2 is 24 plus 24 permanent magnets, and the number of magnetic poles on the rotor 1 is 48 or 24. The sensor detects the position change of the magnetic poles 1-3 on the rotor 1 and transmits the signal to the motor controller. The motor controller supplies power to the conductive blocks 2-4 in sequence. The magnetic fields generated by the conductive blocks 2-4 and the permanent magnets are superimposed, corresponding to the change of the magnetic poles 1-3 on the rotor 1, driving the magnetic poles 1-3 to complete a sector transition on the conductive blocks 2-4. The magnetic fields generated by the permanent magnets and the magnetic fields generated by the conductive blocks 2-4 are superimposed to enhance the magnetic field on the stator 2, which is beneficial to improving the work done by the hollow motor. In this way, as the number of permanent magnets increases, the number of conductive blocks 2-4 decreases, and the input current will also decrease, so that power can be saved while satisfying the magnetic field on the stator 2 to drive the rotor 1 to do work.

[0048] Furthermore, there are 24 conductive blocks 2-4 on the stator 2, and 48 or 24 magnetic poles 1-3 on the rotor 1. The sensor detects the position change of the magnetic poles 1-3 on the rotor 1 and transmits the signal to the motor controller. The motor controller supplies power to the conductive blocks 2-4 in sequence. The magnetic field after the superposition of the conductive blocks 2-4 and the permanent magnets corresponds to the change of the magnetic poles 1-3 on the rotor 1, driving the magnetic poles 1-3 to complete the sector transition on the conductive block 3-2. The power of the hollow motor designed in this way will be lower, but the work of the hollow motor can also be achieved, which can be set according to user needs.

[0049] like Figures 1 to 3 As shown, a turntable or rotating platform is installed on the cover plate 1-2 of the rotor 1 of the hollow motor to form a rotating platform or a turntable, which is driven by the rotor 1 to complete the use of a rotating platform and a turntable. The core of the use of the hollow motor is that the rotor 1 is hollow, so it can be used in more fields, such as rotating platforms and turntables, medical imaging equipment, semiconductor production equipment, and equipment that requires a physical hollow motor in an automated assembly line, to improve the control of the equipment and achieve energy saving.

[0050] like Figure 1-Figure 13 As shown, the stator 2 and the conductive module on the stator 2 and the rotor 1 and the magnetic poles 1-3 on the rotor 1 are combined into a hollow motor, which is compared with the dd motor--DDA hollow motor in the prior art: the dd motor--DDA hollow motor uses 32 kilograms of copper and consumes about 8 degrees of electricity per hour; this product uses 20 kilograms of copper and consumes about 6 degrees of electricity per hour; that is to say, this product saves 12 kilograms of copper and saves about 2 degrees of electricity per hour.

[0051] The conductive film group used in the hollow motor of this product is the core component of the hollow motor. After the hollow motor structure of the conductive film group is upgraded, the efficiency of the hollow motor is improved. As the conductive film group is thicker and the resistance is smaller, the energy lost due to heat in the wire will be smaller, which effectively reduces the winding resistance and thus reduces the copper loss.

[0052] The armature winding in the prior art is designed with coil turns. This product improves the coil turns to hollow conductive blocks 2-4 and uses them in conjunction with permanent magnets, which is convenient for the staff to assemble and disassemble, while also saving extra copper wire at both ends of the coil turns. The cooperation between the permanent magnet and the conductive blocks 2-4 enhances the magnetic field on the stator 2, which is beneficial to improving the work done by the hollow motor.

[0053] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
