Abstract
Description
Technical Field
[0001] The present invention relates to the field of motors, and more particularly to a non-rigid winding, an angular deflection motor using the non-rigid winding, and an assembly process of the angular deflection motor. Background Art
[0002] Currently in the field of motors, whether it is an inner rotor motor or an outer rotor motor, the winding design usually involves designing tooth grooves or tooth crowns, and then using special equipment to wind copper wires on the tooth grooves or tooth crowns to form windings.
[0003] However, the above solutions will lead to magnetic circuit redundancy, and tooth groove torque and iron loss (eddy current + hysteresis loss) account for a large proportion of the overall loss, greatly limiting the efficiency improvement; the filling factor of its rigid copper wire winding is usually insufficient, and it is difficult to achieve a breakthrough in power density. Due to process limitations, the air gap magnetic density uniformity is poor, resulting in torque ripple. In addition, in terms of thermal management, the air gap formed by the conductor curvature of the traditional winding hinders heat dissipation, directly affecting the insulation life. At the same time, traditional windings rely on complex processes such as silicon steel sheet stamping and wire slot winding, relying on manual operation, resulting in high costs, poor consistency, low material utilization rate, and unable to achieve conformal winding of special-shaped rotors. Summary of the Invention
[0004] To solve the above problems, the present application provides a non-rigid winding structure, including an annular substrate made of non-rigid double-layer insulating material. A first energized coil and a second energized coil made of copper foil are embossed on the substrate. The first energized coil and the second energized coil are oppositely arranged on the inner side of the substrate. The first energized coil and the second energized coil are interconnected, and a first connection terminal and a second connection terminal are respectively led out to the outside of the substrate. The first connection terminal is used to connect to a power supply, so that the current passes through the first energized coil and the second energized coil and then leaves from the second connection terminal.
[0005] Furthermore, the first energized coil includes a first inlet portion, and the first connection terminal is connected to the first inlet portion. The copper foil gradually winds inward along the end face of the substrate in a clockwise direction from the first inlet portion to form the first energized coil, and a first outlet portion is formed inside the first energized coil. The second energized coil includes a second inlet portion. Since the substrate is double-layered, the second inlet portion is connected to the first outlet portion inside the substrate. The copper foil gradually winds outward along the end face of the substrate in a clockwise direction from the second inlet portion to form the second energized coil, and a second outlet portion is formed outside the second energized coil. The second connection terminal is connected to the second outlet portion.
[0006] Furthermore, a first reference plane and a second reference plane are respectively formed at the center positions of the first energized coil and the second energized coil, and the first reference plane and the second reference plane are spaced 180 degrees apart.
[0007] Furthermore, the wire pitch in the first energized coil and the second energized coil is between 0.2 and 0.3 mm.
[0008] The present application also provides an angular deflection motor, further including a rotor assembly and a non-rigid winding. The rotor assembly is composed of a rotating shaft and a permanent magnet. The permanent magnet is fixedly covered adjacent to the outer side of the circumferential direction of the rotating shaft. The first energized coil and the second energized coil are suspended outside the permanent magnet and are arranged opposite to each other. A wrapping body is arranged outside the non-rigid winding. The wrapping body forms a wrap around the outer side of the non-rigid winding along the length direction of the non-rigid winding. A channel for the rotor assembly to pass through is arranged in the wrapping body. The non-rigid winding is closely attached to the inner wall of the channel.
[0009] Furthermore, a supporting step is arranged in the channel.
[0010] Furthermore, a supporting shaft is fixed at one end of the rotor assembly. A first bearing is arranged between the supporting shaft and the channel. The outer ring and the inner ring of the first bearing are loosely fitted with the inner wall of the channel and the outer wall of the supporting shaft respectively. A first limiting step is arranged in the channel. The front end and the rear end of the first bearing are respectively clamped between the supporting shaft and the first limiting step.
[0011] Furthermore, a second bearing is arranged between the end of the rotor assembly far from the supporting shaft and the channel. The outer ring and the inner ring of the second bearing are loosely fitted with the inner wall of the channel and the outer wall of the rotating shaft respectively. An elastic gasket is arranged between the side of the supporting step far from the non-rigid winding and the second bearing. The elastic gasket is pre-pressed on one side of the second bearing.
[0012] In addition, the present application also provides an equipment process for an angular deflection motor, including the following steps:
[0013] Step 1: First, place the substrate in the mold and preheat it at 80 °C for 2 minutes. Then, raise the temperature to 120 °C and press the flexible copper foil into the first energized coil and the second energized coil at corresponding positions on the substrate under a pressure of 5 MPa. Then, cool it to 40 °C under pressure and demold it to form a sheet. Finally, weld the first connection terminal and the second connection terminal to the first energized coil and the second energized coil respectively.
[0014] Step 2: Connect the head and tail of the sheet-shaped substrate and curl it into a ring. When the first energized coil and the second energized coil are opposite to each other, place them into the channel of the wrapping body.
[0015] Step 3: Install one end of the rotating shaft on the support shaft, then install the first bearing on the outer wall of the support shaft, then insert the rotating shaft into the channel so that the first bearing contacts the inner wall of the channel, and then install the second bearing on the outer wall of the rotating shaft so that the second bearing contacts the inner wall of the channel.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0017] Compared with the prior art, the present application:
[0018] 1. Compared with traditional windings, the non-rigid winding of the present application is flatter in volume and can be installed on a motor with a smaller volume. Moreover, the flat surface can greatly increase the heat dissipation area, reduce heat loss under the condition of high-speed operation of the motor, and improve its heat dissipation efficiency.
[0019] 2. The present application uses a non-rigid winding to replace the traditional coil winding, so the stator structures such as tooth poles and tooth crowns are eliminated. Therefore, the structure of the overall motor can be more compact, and the volume of the motor can be greatly reduced. In addition, by eliminating the traditional tooth structure of the iron core, the cogging torque and iron loss (eddy current and hysteresis loss) are completely avoided, and the motor efficiency is greatly improved; the flattened winding directly adheres to the stator surface, and the magnetic circuit length is shortened by more than 30%, significantly improving the power density, and at the same time, the axial space can be further compressed; the elastic characteristics of the flexible substrate can also actively compensate for the air gap fluctuation and suppress the torque ripple within a very small range.
[0020] 3. Compared with the traditional installation process, when installing the non-rigid winding of the present application, there is no need to contact glue or other welding processes. Only by using the tension of the non-rigid winding itself, the first energized coil and the second energized coil can be fixed in the channel of the package, and a good suspension effect can be achieved with the permanent magnet. When facing the assembly of a micro-volume motor, it can greatly save the assembly difficulty and time. Moreover, since the whole process does not need to contact chemical agents and welding processes, the whole assembly process is not only efficient but also very environmentally friendly.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

Without otherwise stated, the above terms have no special meanings. Therefore, they should not be construed as limiting the protection scope of the present invention.

[0032] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in this specification in the description of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention.
[0033] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0034] Now, with reference to the drawings, a further description of the preferred embodiments of the present invention is made. As Figure 1 shown, a non-rigid winding structure includes a circular sheet-shaped substrate 110 made of a non-rigid double-layer insulating material. A first energized coil 111 and a second energized coil 112 made of copper foil are embossed on the substrate 110. The first energized coil 111 and the second energized coil 112 are oppositely arranged on the inner side of the substrate 110. The first energized coil 111 and the second energized coil 112 are interconnected, and a first connection terminal 113 and a second connection terminal 114 are respectively led out to the outside of the substrate 110. The first connection terminal 113 is used to connect to a power source, so that after the current passes through the first energized coil 111 and the second energized coil 112, it leaves from the second connection terminal 114.
[0035] The material of the substrate 110 may specifically be a film made of polyimide or polyester material. During preparation, the substrate 110 is first placed in a mold and preheated at 80 °C for 2 minutes, and then heated to 120 °C and under a pressure of 5 MPa, the flexible copper foil is respectively imprinted into a ring-shaped first energizing coil 111 and second energizing coil 112 at corresponding positions on the substrate 110, and then cooled to 40 °C under pressure release for demolding. Finally, the first terminal 113 and the second terminal 114 are respectively welded to the first energizing coil 111 and the second energizing coil 112. Compared with traditional windings, the non-rigid winding 100 is flatter in volume and can be installed on a motor with a smaller volume for use. Moreover, the flat surface can greatly increase the heat dissipation area, reduce heat loss under the condition of high-speed operation of the motor, and improve its heat dissipation efficiency.
[0036] Furthermore, on the basis of the above embodiments, as Figure 2 shown, the first energizing coil 111 includes a first inlet portion 111a, the first terminal 113 is connected to the first inlet portion 111a, and the copper foil gradually winds inward clockwise along the end face of the substrate 110 from the first inlet portion 111a to form the first energizing coil 111, and a first outlet portion 111b is formed inside the first energizing coil 111. The second energizing coil 112 includes a second inlet portion 112a. Since the substrate 110 is double-layered, the second inlet portion 112a is connected to the first outlet portion inside the substrate 110. The copper foil gradually winds outward clockwise along the end face of the substrate 110 from the second inlet portion 112a to form the second energizing coil 112, and a second outlet portion 112b is formed outside the second energizing coil 112. The second terminal 114 is connected to the second outlet portion. In this way, when the first terminal 113 is connected to an external power supply, the current can sequentially pass through the first energizing coil 111 and the second energizing coil 112 and then leave from the second terminal 114.
[0037] Furthermore, on the basis of the above embodiments, as Figure 2 shown, a first reference plane 120 and a second reference plane 130 are respectively formed at the center positions of the first energizing coil 111 and the second energizing coil 112, and the first reference plane 120 and the second reference plane 130 are spaced 180 degrees apart. In this way, when the substrate 110 forms a circular ring, the first energizing coil 111 and the second energizing coil 112 can be oppositely arranged inside the substrate 110, so that after the first energizing coil 111 and the second energizing coil 112 are energized, opposite polarities can be respectively generated.
[0038] Furthermore, on the basis of the above embodiments, as Figure 2As shown, the wire pitch in the first energized coil 111 and the second energized coil 112 is between 0.2 and 0.3 mm. Such a wire pitch can ensure that on the basis of not increasing the process difficulty, the first energized coil 111 and the second energized coil 112 can wind more turns around the end face of the substrate 110 to the greatest extent possible.
[0039] This application also discloses an angle deflection motor, as Figure 3 shown, including a rotor assembly 200 and a non-rigid winding 100. The non-rigid winding 100 adopts the above non-rigid winding 100 structure. The rotor assembly 200 is composed of a rotating shaft 210 and a permanent magnet 220. The adjacent permanent magnets 220 are fixedly covered on the outer side of the circumferential direction of the rotating shaft 210. The first energized coil 111 and the second energized coil 112 are suspended outside the permanent magnet 220 and are arranged opposite to each other in position. A wrapper 300 is arranged outside the non-rigid winding 100. The wrapper 300 forms a wrap around the outer side of the non-rigid winding 100 along the length direction of the non-rigid winding 100. A passage 310 for the rotor assembly 200 to pass through is arranged in the wrapper 300. The non-rigid winding 100 is closely attached to the inner wall of the passage 310, so as to realize that the first energized coil 111 and the second energized coil 112 are outside the permanent magnet 220.
[0040] In the above embodiment, in the rotor assembly 200, since the permanent magnets 220 completely cover and are fixed on the outer side of the circumferential direction of the rotating shaft 210, and the first energized coil 111 and the second energized coil are respectively wound around the outside of the permanent magnet 220 in space, when the first energized coil 111 and the second energized coil are energized, opposite polarities will be generated on the permanent magnet 220 covering the rotating shaft 210, and under the magnetic field effect, the rotating shaft 210 will be driven to rotate inside the non-rigid winding 100. Compared with the prior art, this application uses a non-rigid winding 100 to replace the traditional coil winding, so the stator structures such as tooth poles and tooth crowns are cancelled, so that the structure of the overall motor can be more compact, thereby greatly reducing the volume of the motor. In addition, by eliminating the traditional iron core tooth structure, the cogging torque and iron loss (eddy current and hysteresis loss) are completely avoided, and the motor efficiency is greatly improved; the flattened winding is directly attached to the rotor surface, and the magnetic circuit length is shortened by more than 30%, significantly improving the power density, and at the same time the axial space can be further compressed; the elastic characteristics of the flexible substrate can also actively compensate for the air gap fluctuation and suppress the torque ripple within a very small range.
[0041] Furthermore, on the basis of the above embodiment, as Figure 4As shown, a supporting step 320 is provided in the channel 310. When assembling the present application, the non-rigid winding 100 can be inserted from the side of the channel 310 away from the supporting step 320 and stay on the supporting step 320 after entering the channel 310, thereby preventing the non-rigid winding 100 from moving in the channel 310, which may cause deviation in the magnetic field circuit, and further making the assembly method of the present application simpler.
[0042] Furthermore, based on the above embodiments, in combination with Figure 3 and Figure 4 As shown, a support shaft 230 is fixed at one end of the rotor assembly 200. A first bearing 400 is provided between the support shaft 230 and the channel 310. The outer ring and the inner ring of the first bearing 400 are loosely fitted with the inner wall of the channel 310 and the outer wall of the support shaft 230 respectively. In this way, the support shaft 230 and the channel 310 limit the radial movement of the first bearing 400, so that when the rotating shaft 210 rotates, its radial movement depends on the radial runout accuracy of the first bearing 400, eliminating the influence of other factors (such as machining accuracy), thereby making the radial movement of the rotating shaft 210 more controllable. A first limiting step 330 is arranged in the channel 310. The front end and the rear end of the first bearing 400 are respectively clamped between the support shaft 230 and the first limiting step 330. In this way, the cooperation between the support shaft 230 and the first limiting step 330 forms front and rear limits for the first bearing 400, thereby preventing the first bearing 400 from moving back and forth when the rotating shaft 210 rotates.
[0043] Furthermore, based on the above embodiments, in combination with Figure 3 and Figure 4 As shown, a second bearing 500 is provided between the end of the rotor assembly 200 away from the support shaft 230 and the channel 310. The outer ring and the inner ring of the second bearing 500 are loosely fitted with the inner wall of the channel 310 and the outer wall of the rotating shaft 210 respectively. In this way, the rotating shaft 210 and the channel 310 limit the radial movement of the second bearing 500, so that when the rotating shaft 210 rotates, its radial movement depends on the radial runout accuracy of the second bearing 500, eliminating the influence of other factors (such as machining accuracy), thereby making the radial movement of the rotating shaft 210 more controllable. An elastic gasket 510 is provided between the side of the supporting step 320 away from the non-rigid winding 100 and the second bearing 500. The elastic gasket 510 is pre-pressed on one side of the second bearing 500. In this way, when the rotating shaft 210 deflects radially, it will drive the second bearing 500 to squeeze the elastic gasket 510, so that the second bearing 500 can operate in a stable state as a whole.
[0044] The present application also discloses an assembly process for an angular deflection motor applied to the above non-rigid winding 100, including the following steps:
[0045] Step 1: First, place the substrate 110 in a mold and preheat it at 80°C for 2 minutes. Then, raise the temperature to 120°C and under a pressure of 5 MPa, press the flexible copper foil into the first energized coil 111 and the second energized coil 112 at the corresponding positions on the substrate 110 respectively. Then, cool it to 40°C under pressure and demold it to form a sheet. Finally, weld the first terminal 113 and the second terminal 114 to the first energized coil 111 and the second energized coil 112 respectively. Step 2: Connect the head and tail of the sheet-like substrate 110 and curl it into a ring. When the positions of the first energized coil 111 and the second energized coil 112 are opposite, place it into the channel 310 of the wrapper 300. Since there is an outward tension generated by the substrate 110 after curling, when the substrate 110 curled into a ring will closely adhere to the inner wall of the channel 310, so that the first energized coil 111 and the second energized coil 112 are fixed in the channel 310 of the wrapper 300. Step 3: Install a support shaft 230 at one end of the rotating shaft 210, then install a first bearing 400 on the outer wall of the support shaft 230, then insert the rotating shaft 210 into the channel 310 so that the first bearing 400 contacts the inner wall of the channel 310, and then install a second bearing 500 on the outer wall of the rotating shaft 210 so that the second bearing 500 contacts the inner wall of the channel 310, so that the permanent magnet 220 on the rotating shaft 210 is suspended between the first energized coil 111 and the second energized coil 112. Compared with the traditional assembly process, when installing the non-rigid winding 100 in the present application, there is no need to contact glue or other welding processes. Only by using the tension of the non-rigid winding 100 itself, the first energized coil 111 and the second energized coil 112 can be fixed in the channel 310 of the wrapper 300, and a good suspension effect can be achieved with the permanent magnet 220. When facing the assembly of a micro-volume motor, it can greatly save the assembly difficulty and time. Moreover, since the whole process does not need to contact chemical agents and welding processes, the whole assembly process is not only efficient but also very environmentally friendly.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
