[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. 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.

The shaded-pole motor includes: a stator assembly 1 and a rotor assembly 2 disposed within the stator assembly 1. The stator assembly 1 is formed by laminating a plurality of silicon steel sheets, forming a receiving groove for receiving the rotor assembly 2 within the stator assembly 1, and forming a plurality of installation positions within the stator assembly 1 for placing the coil brackets 11.

[0032] Specifically, the stator assembly 1 is provided with a plurality of coil brackets 11, and a coil structure 3 is arranged on any one of the coil brackets 11. The plurality of coil structures 3 are connected in series based on a connecting wire 6, so that the shaded-pole motor can integrate multiple coil structures 3 to increase the adjustment range of the output power of the shaded-pole motor, enabling the shaded-pole motor to meet the requirements of different power outputs and achieving multi-speed adjustment.

[0033] Furthermore, a plurality of coil brackets 11 are arranged around the rotor assembly 2, such that the rotor assembly 2 is located between the plurality of coil brackets 11, thereby improving the rationality of the spatial utilization of the structural cooperation arrangement between the coil brackets 11 and the rotor assembly 2, making the structural arrangement of the shaded-pole motor compact and simplifying the overall size of the shaded-pole motor.

[0034] The coil bracket 11 is provided with an electrical connection port 113. A plurality of gear adjustment lines and a control main line extend outward from the electrical connection port 113. An output connection line of the shaded-pole motor is constructed based on the plurality of gear adjustment lines and a control main line for electrically connecting the shaded-pole motor.

[0035] Specifically, in this embodiment, the stator assembly 1 is provided with two installation positions for the coil brackets 11, such that two symmetrically distributed coil brackets 11 can be arranged within the stator assembly 1, and the rotor assembly 2 is arranged at the middle position of the stator assembly 1, making the overall structural mass distribution of the shaded-pole motor uniform for the shaded-pole motor to be installed in an external working device.

[0036] Based on the two coil structures 3 arranged on the two coil brackets 11, three gears and a control main line are provided in the shaded-pole motor. The external drive circuit of the shaded-pole motor is accessed through three gear adjustment lines and a control main line, thereby achieving rapid adjustment of the output speed of the shaded-pole motor.

[0037] Furthermore, gear adjustment lines and a control main line are arranged on the coil bracket 11 of one of the coil structures 3 to meet the electrical connection requirements between the shaded-pole motor and an external working circuit. A connecting wire 6 is arranged between the two coil structures 3, enabling the two coil structures 3 to be connected in series, and the rotor assembly 2 is arranged between the two coil structures 3, such that the connecting wire 6 between the two coil structures 3 can be routed below the rotor assembly 2, improving the rationality of the utilization of the spatial structure of the shaded-pole motor.

[0038] Furthermore, the circuit layout of the shaded-pole motor is arranged at the bottom of the shaded-pole motor to avoid the circuit layout structure affecting the rotating shaft of the rotor assembly 2 and ensure that the shaded-pole motor can output normally to meet the usage requirements of the shaded-pole motor.

[0039] Figure 4 The structural schematic diagram of the coil bracket in the embodiment of the present invention is shown. The coil bracket 11 is arranged in an I-shaped cylinder structure, so that the coil bracket 11 can be sleeved on the preset installation position of the stator assembly 1 based on the cylinder structure. The enameled wire is wound around the outer wall of the cylinder of the coil bracket 11, so as to form a coil structure 3 at the cylinder position of the coil bracket 11.

[0040] Based on the I-shaped cylinder structure, the coil bracket 11 is formed with two groups of baffles. The two groups of baffles include a large-size baffle 111 and a small-size baffle 112. When the enameled wire is wound around the cylinder position of the coil bracket 11 to form a coil structure 3, the large-size baffle 111 is folded towards the small-size baffle 112 after being pressed by a pressing device, so that the large-size baffle 111 and the small-size baffle 112 enclose to form a housing structure covering the coil structure 3. Protecting the coil structure 3 based on the housing structure helps to limit and shape the size of the coil structure 3, and at the same time, the coil structure 3 can be protected, reducing the risk of electrical short circuit of the internal structure of the shaded-pole motor.

[0041] Furthermore, the coil structure 3 is protected by wrap-around plastic encapsulation based on the coil bracket 11, so that the coil bracket 11 can insulate and isolate the coil structure 3 and the stator assembly 1, thereby ensuring the working stability of the shaded-pole motor.

[0042] Specifically, a plurality of slots 114 are arranged at the position of the electrical connection port 113 of the coil bracket 11. A plurality of connecting wires 6 extend outwards from the coil structure 3, and the plurality of connecting wires 6 are correspondingly fitted in the plurality of slots 114 one by one. The connecting wires 6 led out by the coil structure 3 are limited by the plurality of slots 114, improving the connection of the connecting wires 6 of the coil structure 3 of the shaded-pole motor.

[0043] Furthermore, an insulating sleeve 62 is sleeved on the connecting wire 6 between any two coil brackets 11. In this embodiment, the two coil brackets 11 are provided with connecting wires 6 for realizing the series connection between the two coil brackets 11. The insulating sleeve 62 is sleeved on the connecting wire 6. The insulating sleeve 62 can protect the connecting wire 6, improve the anti-wear performance of the connecting wire 6, and can effectively reduce the risk of wear of the connecting wire 6 during the installation of the shaded-pole motor.

[0044] Further, the coil bracket 11 is further provided with a plurality of limiting grooves 115, and the plurality of connecting wires 6 are correspondingly arranged in the plurality of limiting grooves 115 of the coil bracket 11. The connecting wires 6 between the coil brackets 11 are limited based on the plurality of limiting grooves 115, so that the connecting wires 6 can be distributed along a preset path between the respective coil brackets 11, reducing the risk of mutual interference of the connecting wires 6, and at the same time improving the simplicity and neatness of the circuit layout of the shaded-pole motor.

[0045] Specifically, a plurality of slots 116 are provided in the electrical connection port 113 of the coil bracket 11, and a wire frame terminal 7 is inserted into any one of the slots 116. The wire frame terminal 7 is configured as a metal electrode sheet structure, which supports the enameled wire led out from the coil structure 3 in the coil bracket 11 and improves the connection convenience between the connecting wire 6 and the electrical connection port 113 of the coil bracket 11.

[0046] Further, one end of the wire frame terminal 7 is inserted into the slot 116, and the other end of the wire frame terminal 7 extends outside the slot 116, so that the enameled wire led out from the coil structure 3 of the coil bracket 11 can be wound around the wire frame terminal 7, thereby forming the electrical connection position of the shaded-pole motor, facilitating the wire connection of the internal coil structure 3 of the shaded-pole motor and the electrical connection between the shaded-pole motor and the external working circuit.

[0047] Specifically, Figure 5 FIG. shows a schematic structural diagram of the wire frame terminal in the embodiment of the present invention. The wire frame terminal 7 includes a connection end 71, a connection section 72, and a plug-in section 73 arranged from top to bottom. The wire frame terminal 7 is inserted into the slot 116 based on the plug-in section 73, so that the connection end 71 and the connection section 72 are located outside the slot 116. The connection end 71 is used to connect the connecting wire 6, so that the respective coil brackets 11 can form a series cooperation based on the connecting wire 6 and be electrically connected to the external working circuit based on the connecting wire 6.

[0048] The connection section 72 is used to connect the enameled wire led out from the coil structure 3 of the coil bracket 11, thereby setting a plurality of speed adjustment gears of the shaded-pole motor.

[0049] Specifically, the connection end 71 is provided with a mating through hole 711, so that the connecting wire 6 can be inserted into the mating through hole 711, thereby realizing the electrical connection between the connecting wire 6 and the wire frame terminal 7. And based on the structure of the mating through hole 711, the mating tightness between the connecting wire 6 and the wire frame terminal 7 can be improved, thereby improving the stability of the electrical structure connection of the shaded-pole motor.

[0050] Furthermore, the material of the wire frame terminal 7 can be copper metal, which has good electrical conductivity and can meet the requirements of the electrical connection structure of the shaded pole motor. The material of the wire frame terminal 7 can also be aluminum metal, which is easy to process and form, meets the electrical connection requirements of the shaded pole motor, and can reduce the manufacturing cost of the shaded pole motor.

[0051] Specifically, a support baffle 721 is provided at the middle position of the connection section 72 of the wire frame terminal 7. Based on the support baffle 721, the connection section 72 is divided into an upper winding area 722 and a lower winding area 723, so that the enameled wire led out from the coil structure 3 of the coil bracket 11 can be wound in the lower winding area 723 and the upper winding area 722 in sequence. That is, the enameled wire is led out from the coil structure 3, so that the enameled wire can be wound in the lower winding area 723 and part of it is led out and wound in the upper winding area 722, so that the enameled wire led out from the coil structure 3 can be close to the coil bracket 11, reducing the size of the suspended area formed between the enameled wire and the coil bracket 11, thereby reducing the risk of extrusion damage to the enameled wire led out from the coil bracket 11 when the shaded pole motor is electrically connected.

[0052] Furthermore, based on the lower winding area 723 and the upper winding area 722, the contact area between the enameled wire led out from the coil structure 3 and the wire frame terminal 7 can be increased, thereby improving the connection stability and reliability between the enameled wire led out from the coil structure 3 and the wire frame terminal 7, so that the electrical connection structure of the shaded pole motor can meet the use requirements of the shaded pole motor.

[0053] Specifically, a plurality of barbs 731 arranged in a serrated shape are provided on the insertion section 73 of the wire frame terminal 7. When the wire frame terminal 7 is inserted into the slot 116 of the coil bracket 11 based on the insertion section 73, the plurality of barbs 731 can squeeze the inner wall of the slot 116, thereby increasing the contact friction between the wire frame terminal 7 and the slot 116, so that the wire frame terminal 7 can be closely fitted in the slot 116, thereby improving the cooperation stability between the wire frame terminal 7 and the coil bracket 11.

[0054] Specifically, Figure 6The structural bottom view of the shaded-pole motor in the embodiment of the present invention is shown. A plurality of adjusting sleeves 61 are provided on the connecting wire 6. The adjusting sleeve 61 is arranged in an L-shaped structure and is sleeved on the connecting wire 6. Based on the adjusting sleeve 61, the folding position and connection direction of the connecting wire 6 are adjusted. Based on a plurality of adjusting sleeves 61, the connection direction of the connecting wire 6 is adjusted, so that the connecting wire 6 can meet the connection requirements between different coil brackets 11, and it helps to adjust and sort out the arrangement structure of the connecting wire 6, improving the rationality and neatness of the arrangement structure of the connecting wire 6 of the shaded-pole motor.

[0055] Furthermore, based on the connecting wire 6, the coil structures 3 of different coil brackets 11 are connected in series, so that the coil structure 3 of the shaded-pole motor can lead out enameled wires of different gears. Based on the enameled wires of different gears being connected to the external working circuit, the shaded-pole motor can adjust the number of turns of the coil structure 3 entering the working state based on the control signal, thereby realizing the output of different speeds of the shaded-pole motor and meeting the usage requirements of the shaded-pole motor.

[0056] Furthermore, the adjusting sleeve 61 can be provided on the wire holder terminal 7. Based on the adjusting sleeve 61, the wire holder terminal 7 is protected by plastic encapsulation, and the line connection direction of the wire holder terminal 7 is adjusted, so that the gear adjustment wire and the control main line of the shaded-pole motor can be integrally arranged, improving the convenience of the electrical connection between the shaded-pole motor and the external working circuit.

[0057] Specifically, the shaded-pole motor is provided with an upper bracket 4 and a lower bracket 5. The upper bracket 4 covers the top surface of the rotor assembly 2, and the lower bracket 5 is arranged on the bottom surface of the rotor assembly 2. The upper bracket 4 and the lower bracket 5 are used to limit and fix the rotor assembly 2.

[0058] Furthermore, a first connection through hole is provided in the middle of the upper bracket 4. The rotating shaft 21 of the rotor assembly 2 extends outside the upper bracket 4 based on the first connection through hole, thereby forming the output shaft of the shaded-pole motor.

[0059] Specifically, the stator assembly 1 is provided with an installation through hole. When the upper bracket 4 and the lower bracket 5 are correspondingly attached to the stator assembly 1, the upper bracket 4 and the lower bracket 5 are locked and fixed by bolts 12, so that the upper bracket 4 and the lower bracket 5 can be fixed on the stator assembly 1.

[0060] Further, the bolt 12 includes a long screw and a nut. The long screw sequentially passes through the upper bracket 4, the stator assembly 1, and the lower bracket 5, and cooperates with the nut to lock the connection position of the screw and the lower bracket 5, so that the long screw extends out of the installation section through the lower bracket 5. Based on the installation section, the convenience of installing and connecting the shaded-pole motor to an external electrical device can be improved.

[0061] Further, the length of the installation section is L1, the length of the long screw is L2, and the constraint relationship between L1 and L2 is: 0.2L2 ≤ L1 ≤ 0.5L2, so that the screw can meet the installation requirements of the electrical equipment of the shaded-pole motor.

[0062] Further, the length of the installation section is greater than the height of the lower bracket 5, so that when the shaded-pole motor is installed on an external device, the lower bracket 5 of the shaded-pole motor can be prevented from causing structural interference to the installation of the shaded-pole motor, ensuring that the shaded-pole motor can be accurately installed on the external working device.

[0063] Specifically, Figure 7 A structural cross-sectional view of the shaded-pole motor in the embodiment of the present invention is shown. A first spherical bearing 23 and a first elastic sheet 22 are arranged inside the upper bracket 4. The first spherical bearing 23 is used to connect the upper bracket 4 and the rotating shaft 21 of the rotor assembly 2 to meet the rotation operation of the rotating shaft 21 of the rotor assembly 2 inside the upper bracket 4. The first elastic sheet 22 is used to adjust the position of the first spherical bearing 23 inside the upper bracket 4 to ensure the installation accuracy of the rotating shaft 21 of the rotor assembly 2.

[0064] A first installation groove 42 for accommodating the first spherical bearing 23 is arranged in the middle of the upper bracket 4. A first cooperation through groove 221 is arranged in the middle of the first elastic sheet 22. The first spherical bearing 23 is divided into an upper hemisphere region and a lower hemisphere region. The upper hemisphere region of the first spherical bearing 23 is fitted in the first installation groove 42, and the lower hemisphere region of the first spherical bearing 23 is fitted in the first cooperation through groove 221, so that the first cooperation through groove 221 and the first installation groove 42 can be symmetrically fitted on the first spherical bearing 23, thereby locking and limiting the first spherical bearing 23 to ensure the accuracy of the installation position of the first spherical bearing 23.

[0065] The first spherical bearing is sleeved on the rotating shaft 21 of the rotor assembly 2. Based on the first spherical bearing 23, the upper bracket 4 and the rotating shaft 21 of the rotor assembly 2 are connected, so that the rotating shaft 21 of the rotor assembly 2 can rotate within the upper bracket 4, that is, relative rotation can be achieved between the rotating shaft 21 of the rotor assembly 2 and the upper bracket 4, thereby meeting the limit of the upper bracket 4 on the rotor assembly 2 and at the same time meeting the rotational output of the rotating shaft 21 of the rotor assembly 2.

[0066] Further, the first installation groove 42 and the first mating through groove 221 are arranged in an arc groove structure, so that the first installation groove 42 and the first mating through groove 221 can fit on the outer contour of the first spherical bearing 23. Based on the first installation groove 42 and the first mating through groove 221, the first spherical bearing 23 can be accurately positioned, ensuring the installation accuracy of the first spherical bearing 23.

[0067] Specifically, the upper bracket 4 is provided with two symmetrically distributed clamping blocks 41. One end of the first elastic sheet 22 abuts against one of the clamping blocks 41, and the other end of the first elastic sheet 22 abuts against the other clamping block 41, so that the first elastic sheet 22 can be clamped and fitted within the upper bracket 4 and the first elastic sheet 22 is in an elastically compressed state. The upper bracket 4 is installed on the stator assembly 1. Based on the first elastic sheet 22, elastic pressure can be applied to the first spherical bearing 23, thereby improving the installation tightness between the first spherical bearing 23, the rotating shaft 21 of the rotor assembly 2 and the upper bracket 4, and thus improving the installation reliability of the shaded-pole motor.

[0068] Specifically, a second spherical bearing 25 and a second elastic sheet 24 are arranged inside the lower bracket 5. The second spherical bearing 25 is used to connect the lower bracket 5 and the rotating shaft 21 of the rotor assembly 2, and the second elastic sheet 24 is used to adjust the installation position of the second spherical bearing 25 to ensure the reliability of the installation fit among the lower bracket 5, the second spherical bearing 25 and the rotating shaft 21 of the rotor assembly 2. A second installation groove for accommodating the second spherical bearing 25 is provided in the middle of the lower bracket 5. A second connection through hole is provided in the second installation groove. The second spherical bearing 25 is fitted in the second installation groove. The second spherical bearing is sleeved on the end of the rotating shaft 21 of the rotor assembly 2. Based on the second spherical bearing 25 connecting the lower bracket 5 and the rotating shaft 21 of the rotor assembly 2, the rotating shaft 21 of the rotor assembly 2 can rotate within the lower bracket 5, that is, relative rotation can be achieved between the rotating shaft 21 of the rotor assembly 2 and the lower bracket 5, thereby meeting the limit of the lower bracket 5 on the rotor assembly 2 and at the same time meeting the rotational output of the rotating shaft 21 of the rotor assembly 2.

[0069] Further, the installation structure and the mating relationship of the second spherical bearing 25, the lower bracket 5, the second elastic sheet 24 and the rotating shaft 21 of the rotor assembly 2 may refer to the structural mating relationship of the upper bracket 4, the first elastic sheet 22 and the first spherical bearing 23, which will not be elaborated here one by one.

[0070] Further, the upper bracket 4 and the lower bracket 5 can be prepared from iron metal. The iron brackets can meet the installation requirements of the shaded-pole motor and reduce the manufacturing cost of the shaded-pole motor at the same time.

[0071] Further, lubricating oil can be coated on the contact positions between the upper bracket 4, the first spherical bearing 23, the lower bracket 5, the second spherical bearing 25 and the rotating shaft 21, so that when the shaded-pole motor is in the working state, the rotating shaft 21 of the rotor assembly 2 can rotate smoothly and output.

[0072] The embodiment of the present invention provides a shaded-pole motor. By setting the installation positions of a plurality of coil brackets 11 on the stator assembly 1, the rotor assembly 2 is arranged between a plurality of coil structures 3, improving the compactness of the arrangement of the multi-coil structures 3 of the shaded-pole motor and realizing a compact packaging structure.
