Description

Technical Field

[0001] The present invention relates to the technical field of stator wire embedding, and more particularly to stator wire embedding of an AC permanent magnet servo motor with auxiliary insulation. Background Art

[0002] The stator wire of the AC permanent magnet servo motor is an important part of the motor. It is mainly composed of the stator core and the enameled wire embedded in it. The stator core is provided with multiple slots for placing the enameled wire. In order to enhance the insulation effect, slot insulation paper is set between the enameled wire and the inner wall of the slot, which is an auxiliary insulation measure.

[0003] Among them, the patent with publication number CN213072249U discloses a stator wire of an AC permanent magnet servo motor, including a stator core; a plurality of slots are arranged on the stator core; enameled wires are placed in the slots, slot insulation paper is arranged between the enameled wires and the inner wall of the slots, and the end of the slot insulation paper is flush with the port edge of the slot; a guide film is installed between the slot insulation paper and the inner wall of the slot, and the end of the guide film extends out of the port of the slot.

[0004] When this structure is in use, the slot insulation paper is conveniently placed on the stator core through the guiding film, so that the slot insulation paper is placed in place and the insulation effect is improved. However, when this structure is in use, the insulation paper is loosely placed and may deviate from the position or be misplaced. At the same time, when the coil is not straight or misplaced, it is easy to cause damage to the internal insulation of the coil when it is embedded in the slot. Summary of the invention

[0005] In order to overcome the above defects of the prior art, the present invention provides an AC permanent magnet servo motor stator insert with auxiliary insulation, aiming to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: an auxiliary insulated AC permanent magnet servo motor stator wire embedding includes a bottom plate, on which a positioning wire embedding assembly is arranged.

[0007] The positioning wire assembly includes a supporting ring arranged on the top of the base plate, a plurality of limiting plates are inserted into the top of the base plate, and each limiting plate is threadedly connected to a column, the top ends of the plurality of columns extend to the supporting ring and are rotatably connected to the supporting ring, a plurality of limiting plates are provided with a vertical rod on one side, and each of the vertical rods is fixed to the base plate, a support plate is installed on the top ends of the plurality of vertical rods by bolts, and one end of the support plate extends to the second center circle and is clamped with the second center circle.

[0008] A first center ring is arranged on the top of the support ring, a second center ring is clamped on the top of the first center ring, the second center ring and the first center ring are stacked, a plurality of first nylon plywood are fixedly arranged on the outer side of the first center ring, a plurality of second nylon plywood are fixedly arranged on the outer side of the second center ring, and a combing cavity is formed between each two adjacent first nylon plywood and second nylon plywood, elastic plywood is arranged on both sides of the second nylon plywood and the first nylon plywood, positioning rings are arranged in the middle of the second center ring and the first center ring, a plurality of wire management rods are clamped on the positioning rings, and a center tube is clamped between each of the wire management rods, and the center tube is located at the bottom of the core disk.

[0009] It can be seen that in the above technical scheme, the wires are combed by the first nylon splint and the second nylon splint to avoid the wires being intertwined, and the elastic splint positions the wires to avoid the insulation paper being too loosely placed in the combing cavity to deviate from the position or be misplaced when the wires are embedded. The wire manager rod blocks and straightens the wires, and the elastic splint combs the coils when they are not straight or misplaced to avoid the coils being misplaced and deformed, resulting in the hidden danger of internal insulation damage such as scratches and strains on the insulation between turns inside the coil.

[0010] An iron core disk is arranged on the top of the second center ring, and a plurality of embedded holes are opened through the outer side of the iron core disk, an outer retaining ring is arranged on the top of the iron core disk, and a mounting rail is inserted in the middle of the outer retaining ring, and a plurality of insulating frames are arranged on the outer side of the mounting rail, and arc frame openings are opened through the plurality of insulating frames, and the insulating frame is sleeved on the mounting rail through the arc frame openings, and a positioning groove is opened on the surface of the insulating frame, and a conductive winding is sleeved in the positioning groove, and a plurality of pins are fixedly arranged on the outer side of the conductive winding, and the conductive winding is wound on the insulating frame, and the pins are embedded in the insulating frame, and the cross-sectional shapes of the arc frame opening and the mounting rail are both arc-shaped, and the insulating frame is slidably connected with the mounting rail through the arc frame opening, and a plurality of abutting blocks are arranged on the top of the embedded hole, and each of the abutting blocks is mounted on the iron core disk by bolts, and a plurality of the abutting blocks are distributed in a triangle, and a central supporting ring is arranged in the middle of the iron core disk, and one end of the abutting block extends to the central supporting ring.

[0011] It can be seen that in the above technical scheme, when embedding the wire, one end of the wire body is combed by the combing cavity and then passes through each corresponding embedded hole. The insulating paper is positioned through the embedded hole, which makes it easy for the insulating paper to wrap the wire body to avoid circuit short circuit or leakage. It can form an isolation layer between the conductor and the external environment, isolate external electromagnetic waves and interference signals, and avoid electromagnetic waves and interference signals from interfering with and damaging the circuit. Each insulating frame is supported by the mounting rail, and the insulating frame supports and insulates the wire body to ensure circuit safety and reliability, isolate external interference, and adapt to different use environments. When the wire body and the conductive winding are welded together, the conductive winding is wound on the insulating frame, which is easy to disperse the solder joints while avoiding looseness or defects. It also makes the current transmission more direct, reduces energy consumption, avoids heat accumulation at the solder joints during the current transmission process, and causes the solder joints to crack or fall off, and reduces the motor failure rate caused by poor insulation.

[0012] Technical effects and advantages of the present invention:

[0013] 1. The present invention combs the wires through the first nylon clamp and the second nylon clamp to prevent the wires from being intertwined. At the same time, the elastic clamp positions the wires to prevent the insulating paper from being too loosely placed in the combing cavity and deviating from the position or being misplaced when the wires are embedded;

[0014] 2. The present invention uses a wire manager rod to block and straighten the wire body, and at the same time, the elastic clamping plate can be used to straighten the coil when it is not straight or misplaced, so as to avoid the misplacement and deformation of the coil, resulting in the hidden danger of internal insulation damage such as scratches and strains on the insulation between turns inside the coil;

[0015] 3. When the wire is embedded in the present invention, one end of the wire body is combed by the combing cavity and then passes through each corresponding embedded hole. The insulating paper is positioned through the embedded hole, which makes it easy for the insulating paper to wrap the wire body to avoid short circuit or leakage of the circuit. It can form an isolation layer between the conductor and the external environment to prevent electromagnetic waves and interference signals from interfering with and damaging the circuit.

[0016] 4. The insulating frame of the present invention supports and insulates the wire body, ensuring the safety and reliability of the circuit, isolating external interference and adapting to different use environments. When the wire body and the conductive winding are welded together, the conductive winding is wound on the insulating frame, which is easy to disperse the welding points and can avoid being loose or defective. It also makes the current transmission more direct, reduces energy consumption, avoids heat accumulation at the welding point during the current transmission process, and causes the welding point to crack or fall off, and reduces the motor failure rate caused by poor insulation;

[0017] To sum up, through the corresponding coordinated use of various structures, the wires are prevented from being intertwined, and the elastic splint is used to position the wires to avoid the phenomenon of deviation or dislocation of the insulating paper when it is too loosely placed in the combing cavity when the wire is embedded. The wire manager rod blocks and straightens the wires, and the elastic splint is used to comb the coils when they are not straight or misplaced when embedded, to avoid the coils from being misplaced and deformed, causing the hidden danger of internal insulation damage such as scratches and strains on the insulation between turns of the coil. At the same time, one end of the wire is combed by the combing cavity and then passes through the corresponding embedded holes. The insulating paper is positioned through the embedded holes, which makes it easy for the insulating paper to wrap the wires to avoid circuit short circuit or leakage.

At the same time, the elastic clamps position the wires to avoid the insulating paper being too loosely placed in the combing cavity 204 to deviate from the position or be misplaced when embedding the wires.

[0041] Different from the prior art, the present application discloses an AC permanent magnet servo motor stator wire embedding with auxiliary insulation. Through the corresponding coordination of various structures, the wires are prevented from being intertwined. At the same time, the elastic splint is used to position the wires to prevent the insulating paper from being too loosely placed in the combing cavity 204 and deviating from the position or being misplaced when the wires are embedded. The wire manager rod 206 blocks and straightens the wires. At the same time, the elastic splint is used to comb the coils when they are not straight or misplaced when embedded, to avoid the coils from being misplaced and deformed, causing the hidden danger of internal insulation damage such as scratches and strains on the insulation between turns of the coil. At the same time, one end of the wire is combed by the combing cavity 204 and then passes through each corresponding embedded hole 301. The insulating paper is positioned through the embedded hole 301, which makes it easy for the insulating paper to wrap the wires to avoid circuit short circuit or leakage.
