Furthermore, the drawings are not 1: 1, and the relative dimensions of the various elements in the figures are drawn for illustration only and not necessarily to true scale.

Referring to fig. 1, the present invention provides a pole coil winding auxiliary device 10 and a pole coil winding system (not shown). The pole coil winding system includes a winding device (not shown) and a pole coil winding auxiliary device 10. The auxiliary device 10 for winding the magnetic pole coil is matched with winding equipment, so that the magnetic pole coil can be wound in a shuttle shape. The winding device includes a winding template (not shown). A winding die cavity (not shown) is formed on the winding die plate.

Because the magnetic pole coil is in the shape of a shuttle with a large length and a small width, when the flat copper wire 20 is wound to different positions of the magnetic pole coil (for example, the end of the magnetic pole coil and the straight line segment of the magnetic pole coil in the longitudinal direction), the position of the winding die cavity moves in the direction close to or away from the rotating shaft of the winding template, so in the background art, in order to ensure the winding effect of the shuttle-shaped end of the magnetic pole coil, the distance between the winding equipment and the pressing assembly 300 for pressing the flat copper wire 20 is usually set to be large, so that the length of the tail end of the flat copper wire 20 to be cut off is very long, and the problem of serious waste of the flat copper wire 20 is caused. The pole coil winding auxiliary device 10 of the invention has the advantages that through the ingenious design, the position of the pressing component 300 in the pole coil winding auxiliary device 10 changes along with the change of the position of the winding die cavity in the winding equipment, so that the problem of high spindle-shaped processing cost of the pole coil caused by serious waste of the copper flat wire 20 in the background art is well solved.

Referring to fig. 1 again, the pole coil winding auxiliary device 10 in the preferred embodiment of the present invention includes a fixing base 100, a cross member 200 and a pressing member 300.

The fixing base 100 mainly plays a supporting role, and is generally made of stainless steel, alloy steel, cast iron and other materials with relatively high strength, so that the fixing base 100 has relatively high bearing capacity. The fixing base 100 may have a frame structure, a shell structure, a solid structure, or the like.

The cross beam 200 is rotatably connected with the fixing base 100. The end of the beam 200 away from the fixing base 100 is a free end 220. The fixing base 100 may be rotatably connected to an end of the cross beam 200 far from the free end 220, or rotatably connected to a middle portion of the cross beam 200. Specifically, two ends of the cross beam 200 are respectively a free end 220 and a fixed end 210, and the fixed end 210 is rotatably connected to the fixing base 100, so that the volume of the pole coil winding auxiliary device 10 is small. The beam 200 is a rod-shaped structure, and may be square steel, channel steel, steel plate, or the like. Specifically, the cross beam 200 is a channel steel, so that the use strength of the cross beam 200 is ensured, and the processing procedure of the cross beam 200 is simplified.

Referring also to fig. 2, a hold-down assembly 300 is mounted to the free end 220. The pressing assembly 300 is formed with a pressing groove 310. The size of the wire-pressing groove 310 is adjustable in a direction perpendicular to the extending direction of the wire-pressing groove 310, so that the flat copper wire 20 is pressed in the wire-pressing groove 310. The compression assembly 300 may be mounted on the upper surface or side of the beam 200. Particularly in this embodiment. The cross-sectional shape of the wire-pressing groove 310 may be rectangular, trapezoidal, polygonal, or irregular. The compressing assembly 300 may be installed on the upper surface of the cross member 200, or may be installed on the side surface of the cross member 200. The direction perpendicular to the extending direction of the wire-pressing groove 310 is a direction parallel to the cross section of the flat copper wire 20 in the groove, that is, the depth direction or the width direction of the wire-pressing groove 310. That is, when the flat copper wire 20 needs to be compressed in the flat copper wire 20, only the depth or the width of the wire-compressing groove 310 needs to be adjusted.

When the flat copper wire 20 pressed in the wire pressing groove 310 slides relative to the inner wall of the wire pressing groove 310, the free end 220 swings left and right around the connection part of the cross beam 200 and the fixed seat 100. Specifically, the free end 220 swings back and forth along a fan-shaped track around the fixed end 210 under the pulling action of the flat copper wire 20 pressed in the wire pressing groove 310.

Specifically, the pressing assembly 300 is disposed on a side of the cross beam 200 facing away from the fixing base 100. When the pole coil winding auxiliary device 10 is located on the horizontal plane, the fixing base 100 is located on the lower side of the cross beam 200, and the pressing assembly 300 is located on the upper side of the cross beam 200, so as to facilitate the pressing of the flat copper wire 20 and the transportation of the flat copper wire 20 to the winding equipment.

In the process of carrying out shuttle winding on the magnetic pole coil by using a magnetic pole coil winding system, the copper flat wire 20 on the wire frame needs to be pulled out and penetrates through the wire pressing groove 310 until the copper flat wire 20 reaches a winding mold cavity of a winding device; then, the size of the wire pressing groove 310 is adjusted to tightly press the copper flat wire 20 in the wire pressing groove 310; and then starting the winding equipment, wherein the winding template rotates to apply a pulling force which is enough to pull the copper flat wire 20 tightly pressed in the wire pressing groove 310 to the copper flat wire 20, and at the moment, the copper flat wire 20 is in a tensioning state to ensure the winding effect of the fusiform end part of the magnetic pole coil.

Moreover, since the pole coil is in the shape of a shuttle with a small width and a large length, when the copper flat wire 20 is wound to different positions of the pole coil (for example, the end of the pole coil, the straight line segment of the pole coil in the longitudinal direction) in the winding process, the stress directions of the copper flat wire 20 are different, so that the free end 220 swings back and forth along the fan-shaped track under the influence of the copper flat wire 20, and therefore, only a small distance needs to be kept between the pressing component 300 and the winding mold cavity, the winding effect of the shuttle shape of the pole coil can be ensured, when the copper flat wire 20 is wound to the tail end of the copper flat wire 20 to be close to the wire pressing component, the tail end of the copper flat wire 20 which needs to be cut off is short in length, the waste of the copper flat wire 20 can be reduced or avoided, and the processing cost. Since the copper flat wire 20 is expensive, in actual production, the magnetic pole coil winding auxiliary device 10 can reduce the material cost by thousands or even tens of thousands for each project, which is beneficial to the improvement of market competitiveness.

In the winding process of the magnetic pole coil, when the winding die cavity drives the copper flat wire 20 to wind to the fusiform end part of the magnetic pole coil, the free end 220 swings to the end part of the fan-shaped track under the traction of the copper flat wire 20, and the distance between the pressing component 300 and the rotating shaft of the winding template is the largest; when the winding die cavity drives the copper flat wire 20 to wind to the shuttle-shaped straight section of the magnetic pole coil, the free end 220 swings to the middle position of the fan-shaped track under the traction of the copper flat wire 20, and the distance between the pressing assembly 300 and the rotating shaft of the winding template is the minimum. In this way, when the free end 220 of the beam 200 swings left and right, a stable distance value can be maintained between the winding die cavity and the hold-down assembly 300 no matter where the flat copper wire 20 is wound to the pole coil.

Therefore, in the pole coil winding system, since the pressing member 300 can swing left and right along with the free end 220, the distance between the winding apparatus and the pole coil winding auxiliary device 10 is set to be very close, and the pole coil winding system can realize the shuttle-shaped winding of the pole coil while ensuring the winding effect. When the distance between the winding device and the auxiliary winding device 10 of the pole coil is set to be short, the distance between the winding die cavity and the pressing assembly 300 is also short, so that the length of the tail end of the copper flat wire 20 to be cut off is short in the winding process of the pole coil.

Referring to fig. 1 to 3, in some embodiments, the pressing assembly 300 includes two pressing plates 320 and a fastening adjuster 330. The two tension plates 320 are stacked in a direction perpendicular to the surface of the cross member 200. A surface of each of the tension plates 320 facing the other tension plate 320 is formed with a tension groove 321. The inner walls of the two wire pressing grooves 321 enclose a wire pressing groove 310. The fastening adjusting member 330 is sequentially installed on the two tension plates 320 and connected with the cross beam 200 to adjust the size of the tension groove 310. Specifically, the end surface of one end of the tension disc 320 is flush with the end surface of the free end 220. The wire pressing plate 320 may be made of a material with good electrical insulation performance and a soft material, such as rubber, plastic, wood, and the like. The fastening adjusting piece 330 is used for installing the two tension plates 320 on the cross beam 200, and the distance between the two tension plates 320 can be adjusted through the fastening adjusting piece 330, so that the size of the tension groove 310 can be adjusted. The depth of the wire pressing groove 321 is less than or equal to one half of the thickness of the copper flat wire 20, so as to ensure that the copper flat wire 20 can be effectively pressed in the wire pressing groove 310.

When the copper flat wire 20 needs to be compressed in the wire pressing groove 310, after the copper flat wire 20 passes through the wire pressing groove 310, the copper flat wire 20 can be compressed in the wire pressing groove 310 only by screwing the fastening adjusting piece 330, so that the operation of compressing the copper flat wire 20 in the wire pressing groove 310 is simplified.

Specifically, the fastening adjuster 330 includes a bolt 331 and a nut 332. The tension plate 320 is provided with a mounting hole (not shown), and the cross beam 200 is provided with a connecting hole (not shown) at a position opposite to the mounting hole. The bolts 331 sequentially pass through the mounting holes of the two tension plates 320 and the connecting holes of the cross beam 200 and are screwed with the nuts 332 to mount the two tension plates 320 on the cross beam 200. In the actual use process, the two line pressing plates 320 can be loosened or tightened by screwing the nuts 332 or the bolts 331, so that the size of the line pressing groove 310 can be reduced or increased.

Referring again to fig. 1 and 2, further, in some embodiments, the pressing assembly 300 further includes a pressing hard plate 340. The pressing hard plate 340 and the two wire pressing plates 320 are sequentially stacked and arranged on one side, away from the cross beam 200, of the wire pressing plates 320. The fastening adjusting member 330 is sequentially installed on the pressing hard plate 340 and the two wire pressing plates 320, and is connected with the cross beam 200. The pressing hard plate 340 can be made of alloy steel, cast iron, stainless steel and other materials with high hardness and strength. In order to reduce the wear on the flat copper wire 20, the wire pressing plate 320 is usually made of a material with a relatively soft material, and if the fastening adjusting member 330 is directly connected with the wire pressing plate 320, the fastening adjusting member 330 with a relatively hard material may damage the wire pressing groove 310, which greatly affects the service life of the wire pressing plate 320. Therefore, the pressing hard plate 340 is arranged, the pressing hard plate 340 can be arranged on one side, away from the cross beam 200, of the line pressing plate 320, the fastening adjusting piece 330 exerts pressing force on the line pressing plate 320 through the pressing hard plate 340, and the fastening adjusting piece 330 cannot damage the line pressing plate 320 due to the fact that the pressing hard plate 340 is made of hard materials, and therefore the service life of the line pressing plate 320 is prolonged.

Referring again to figures 1 and 2, in some embodiments, the magnetic coil winding aid 10 further comprises a support assembly 400. The support assembly 400 includes a support structure 410 disposed at the free end 220. The support assembly 400 includes a support structure 410 disposed at the free end 220. The support structure 410 is located on the same side of the beam 200 as the anchor 100. When the free end 220 swings left and right under the pull of the flat copper wire 20, the support structure 410 also swings back and forth along the fan-shaped trajectory with the free end 220. Therefore, the supporting structure 410 is located on the lower side of the beam 200 and is used for supporting the free end 220 of the beam 200, so that the situation that the free end 220 shakes up and down in the winding process can be avoided, and the shuttle-shaped winding effect of the magnetic pole coil is further improved.

Further, in some embodiments, the support structure 410 is retractable in a vertical direction to adjust the height of the wire-pressing trough 310. The supporting structure 410 may be a telescopic rod, a telescopic cylinder, or other structures with variable length. In the pole coil winding system, the height of the wire pressing groove 310 can be adjusted through the supporting structure 410, so that the height of the wire pressing groove 310 is matched with the height of a winding mold cavity in the winding device, and the pole coil winding system is ensured to have a better winding effect. Moreover, the same pole coil winding auxiliary device 10 can be matched with winding equipment with different specifications, and the applicability of the pole coil winding auxiliary device 10 is greatly improved.

Referring to fig. 1 and 4, in the present invention, a lifting/lowering adjusting post 510 is installed on the fixing base 100. One end of the lifting adjusting column 510 away from the fixing base 100 is rotatably connected with the cross beam 200. The elevation adjustment post 510 is retractable with respect to the fixing base 100 to adjust the height of the cross beam 200. Specifically, when the lifting adjusting member is retracted downward relative to the fixing base 100, the height of the cross beam 200 can be adjusted downward; when the lifting adjusting column 510 extends upward relative to the fixing base 100, the height of the cross beam 200 can be adjusted to be high. By adjusting the height of the cross beam 200, the height of the wire pressing groove 310 is matched with the height of the winding cavity, so that the winding effect of the pole coil winding system is ensured. Moreover, the lifting adjusting column 510 is provided, so that the pole coil winding auxiliary device 10 can be adapted to a plurality of winding devices of different specifications, thereby improving the applicability of the pole coil winding auxiliary device 10.

It should be noted that, in the embodiment of the present invention, the supporting structure 410 is configured as a retractable structure, or the fixed base 100 is provided with the lifting adjusting column 510 retractable with respect to the fixed base 100, and the pole coil winding auxiliary device 10 adjusts the height of the cross beam 200 by adjusting the length of the supporting structure 410 or making the lifting adjusting column 510 retractable with respect to the fixed base 100; of course, the supporting structure 410 may be a telescopic structure, and the lifting/lowering adjusting column 510 is provided on the fixing base 100 and is telescopic with respect to the fixing base 100, and at this time, the pole coil winding auxiliary device 10 may adjust the height of the cross beam 200 by adjusting the length of the supporting structure 410 and simultaneously extending and retracting the lifting/lowering adjusting column 510 with respect to the fixing base 100. In the present embodiment, the supporting structure 410 is a retractable structure, and the fixing base 100 is provided with a lifting/lowering adjusting column 510 retractable with respect to the fixing base 100.

Referring again to fig. 1 and 2, the following is a detailed description of the structure of the support assembly 400:

the supporting structure 410 includes a supporting frame 411 fixed on the cross beam 200 and an adjusting supporting rod 412 installed at an end of the supporting frame 411 far away from the cross beam 200. The adjustable support bar 412 is operable to telescope in a vertical direction relative to the support frame 411 to adjust the length of the support structure 410. Therefore, the length of the supporting structure 410 can be adjusted by adjusting the installation position of the supporting frame 411 on the adjusting supporting rod 412.

Specifically, the installation relationship between the adjusting support bar 412 and the support frame 411 includes the following: firstly, the adjusting support bar 412 is provided with a plurality of installation positions at intervals along the vertical direction, and the support frame 411 is detachably installed on any installation position, so that the length of the support frame 411 can be adjusted by installing the support frame 411 on different installation positions of the adjusting support bar 412; secondly, the supporting frame 411 is provided with a plurality of installation positions at intervals along the vertical direction, and the adjusting support rod 412 is detachably installed at any installation position, so that the length of the supporting structure 410 can be adjusted by installing the adjusting support rod 412 at different installation positions of the supporting frame 411; thirdly, the adjusting support rod 412 is movable in the vertical direction relative to the support frame 411, and the adjusting support rod 412 can be clamped on the support frame 411 by using a clamping piece; fourthly, the adjusting support rod 412 is screwed with the support frame 411, and the stretching of the adjusting support rod 412 relative to the support frame 411 can be realized by screwing the adjusting support rod 412.

In the embodiment of the present invention, a threaded hole (not shown) is formed on the supporting frame 411, and the adjusting support bar 412 is a threaded support bar. The adjusting support bar 412 is screwed in the threaded hole. Specifically, support frame 411 includes adjusting nut 4111 and supporting plate 4112, and the both ends of supporting plate 4112 are respectively with adjusting nut 4111 and crossbeam 200 fixed connection, are formed with above-mentioned screw hole in the adjusting nut 4111. More specifically, adjusting nut 4111 is the square nut, and backup pad 4112 is a plurality of, and a plurality of backup pads 4112's one end all with the square nut towards one side fixed connection of crossbeam 200, the other end all with crossbeam 200 fixed connection. Therefore, when the height of the line pressing groove 310 needs to be adjusted, only the adjusting support rod 412 needs to be screwed, so that the height of the free end 220 can be adjusted simply.

Further, the support assembly 400 further includes a latch 414. The locking member 414 is mounted on the adjusting support rod 412 and is used for locking the position of the support frame 411 on the adjusting support rod 412. Therefore, the locking piece 414 can lock the installation position between the adjusting support rod 412 and the support frame 411, thereby avoiding the situation that the length of the support structure 410 is changed due to the looseness of the adjusting support rod 412 relative to the support frame 411 after long-time use, and improving the reliability of the pole coil winding auxiliary device 10.

Specifically, when the adjusting support rod 412 is a threaded support rod and the support frame 411 is formed with a threaded hole, the locking member 414 is a nut. In practical use, when screwing the adjusting support rod 412, when the length of the support structure 410 reaches a suitable length, the locking nut is screwed to abut against the support frame 411, so that the adjusting support rod 412 is locked on the support frame 411.

In some embodiments, the bottom of the support structure 410 is provided with rollers 420. Specifically, when the supporting structure 410 includes the supporting frame 411 and the adjusting supporting rod 412, the roller 420 is disposed at an end of the adjusting supporting rod 412 away from the supporting frame 411. During the winding of the pole coil shuttle, as the support structure 410 swings with the free end 220 along a fan-shaped path, the roller 420 also rolls on the ground along the fan-shaped path. Therefore, the roller 420 is disposed to facilitate and smooth the movement of the supporting member 400 along with the free end 220 on the ground.

Referring to fig. 1 and 4 again, the following is a detailed description of the mounting structure between the lifting adjusting column 510 and the fixing base 100 and the cross beam 200 respectively:

the fixing base 100 is formed with an adjustment screw hole (not shown). The lift adjustment post 510 is a threaded post. The lifting adjusting post 510 is threaded into the adjusting screw. Therefore, by screwing the lifting adjusting column 510, the lifting adjusting column 510 can be extended and retracted relative to the fixed seat 100, and the height of the cross beam 200 can be adjusted. Specifically, the pole coil winding auxiliary device 10 further includes a mounting nut 550, the fixing base 100 is provided with a through hole (not shown) to which the mounting nut 550 is fixed, and the mounting nut 550 is fixed on the fixing base 100 and is communicated with the through hole, so that an adjusting screw hole can be formed on the fixing base 100.

Specifically, the lifting/lowering adjusting post 510 is provided with a locking member 520, and the locking member 520 is used to lock the fixing base 100 in place on the lifting/lowering adjusting post 510. The locking member 520 may be a connecting member that is mounted on the fixing base 100 and can abut against the lifting/lowering adjusting column 510, a clamping member that is mounted on the lifting/lowering adjusting column 510 and can be clamped with the fixing base 100, or other structures for preventing the lifting/lowering adjusting column 510 from moving relative to the fixing base 100. Therefore, the locking member 520 is disposed to reduce the probability of the lifting/lowering adjusting column 510 descending relative to the fixing base 100 during the winding process, thereby improving the reliability of the pole coil winding auxiliary device 10.

When the lift adjustment post 510 is a threaded post, the locking member 520 is a lock nut. When the lifting adjusting column 510 is twisted to adjust the height of the beam 200 to a preset height, the lifting adjusting column 510 can be locked on the fixing base 100 only by twisting the locking member 520 to abut against the fixing base 100.

In one embodiment, a mounting seat 530 is fixed to a side of the beam 200 facing the fixing seat 100. A rotation hole is formed at a side of the mounting seat 530 facing the fixing seat 100. One end of the lifting adjusting column 510 facing away from the fixing base 100 is rotatably inserted into a rotating hole (not shown). Specifically, the elevation adjustment post 510 is rotatably mounted in the rotation hole through a bearing (not shown). Of course, in other embodiments, the lift adjustment post 510 may be rotatably mounted in the rotation hole via other mechanisms.

Referring to fig. 1 and 4 again, in some embodiments, the pole coil winding auxiliary device 10 further includes a wire assembly 600 disposed at an end of the beam 200 close to the fixing base 100. The wire assembly 600 is located on the same side of the beam 200 as the compression assembly 300. The wire guide assembly 600 has a wire guide groove 610 formed therein. The extension direction of the wire groove 610 coincides with the extension direction of the pressing groove. Wherein, the wire groove 610 is used for guiding the flat copper wire 20 on the crossbeam 200, so that the flat copper wire 20 can be neatly arranged on the crossbeam 200, and guarantee that the flat copper wire 20 is stable to the inlet wire direction of the wire-pressing groove 310, avoid when the free end 220 swings because the flat copper wire 20 makes the unstable condition of wire winding effect take place to the random change of the inlet wire direction of the wire-pressing groove 310, so wire assembly 600's setting is favorable to the improvement of magnetic pole coil quality stability. The cross-sectional shape of the wire groove 610 may be rectangular, trapezoidal, polygonal, or irregular.

Specifically, the guide groove and the wire pressing groove 310 are rectangular grooves. Because the cross section of the flat copper wire 20 is rectangular, the wire groove 610 and the wire-pressing groove 310 are both rectangular grooves, which is beneficial to the compression of the flat copper wire 20 in the wire-pressing groove 310 and the sliding of the flat copper wire 20 in the wire-pressing groove 310 and the wire groove 610.

Specifically, the wire guide slots 610 and the wire crimping slots 310 are aligned along the lengthwise direction of the beam 200. That is, the bottom wall of the guide groove is the same as the bottom wall of the wire-pressing groove 310 in height, so that the section of the flat copper wire 20 between the wire guide groove 610 and the wire-pressing groove 310 extends along the longitudinal direction of the cross beam 200, and the wire-feeding direction of the flat copper wire 20 to the wire-pressing groove 310 is the same as the extending direction of the wire-pressing groove 310.

Further, in some embodiments, the lead assembly 600 includes a first pressing plate 620, a second pressing plate 630 stacked with the first pressing plate 620, and a retaining member 640. A first guide groove is formed on one side of the first pressing plate 620 facing the second pressing plate 630. The second pressing plate 630 is provided with a second guide groove at a position opposite to the first guide groove. The first guide slot and the second guide slot enclose a wire guide slot 610. The locking member 640 is sequentially installed on the first pressing plate 620 and the second pressing plate 630 and connected to the cross beam 200 to fix the first pressing plate 620 and the second pressing plate 630 on the cross beam 200. The locking member 640 may be a bolt, a screw, a rivet, a buckle, etc., as long as the first pressing plate 620 and the second pressing plate 630 can be pressed and mounted on the cross beam 200.

Since the wire groove 610 is surrounded by the first guide groove and the second guide groove, when the flat copper wire 20 moves in the wire groove 610, the flat copper wire 20 can be prevented from coming out of the wire groove 610 when the flat copper wire 20 moves in the wire groove 610, and the reliability of the pole coil winding auxiliary device 10 is improved.

Further, the first pressing plate 620 may be replaced with the wire pressing plate 320, so as to simplify the processing procedure of the pole coil winding auxiliary device 10 and reduce the processing cost. At this time, the depth of the first guide groove (i.e., the wire pressing groove 321) is less than or equal to one half of the thickness of the flat copper wire 20, so as to conveniently press the flat copper wire 20 in the wire pressing groove 310; the depth of the second guiding groove is greater than or equal to the thickness of the flat copper wire 20, so as to facilitate the movement of the flat copper wire 20 in the wire guiding groove 610.

In some embodiments, the components of the compression assembly 300 used to form the wire chase 310 and/or the components of the wire assembly 600 used to form the wire chase 610 are alkali-free glass cloth-impregnated epoxy boards. Specifically, the first pressing plate 620 and the second pressing plate 630 are alkali-free glass cloth-impregnated epoxy resin plates, and/or the wire pressing plate 320 is an alkali-free glass cloth-impregnated epoxy resin plate. Therefore, in the present invention, only the first pressing plate 620 and the second pressing plate 630 may be provided as the alkali-free glass cloth-impregnated epoxy resin plate, only the wire pressing plate 320 may be provided as the alkali-free glass cloth-impregnated epoxy resin plate, or all of the first pressing plate 620, the second pressing plate 630, and the wire pressing plate 320 may be provided as the alkali-free glass cloth-impregnated epoxy resin plate.

If the wire pressing plate 320, the first pressing plate 620, and the second pressing plate 630 are made of a hard material, copper powder adheres to the inner walls of the wire pressing groove 310 and the wire guiding groove 610 after the copper flat wire 20 is rubbed in the wire pressing groove 310 and the wire guiding groove 610, and the surface of the copper flat wire 20 is easily damaged or burrs are generated on the surface of the copper flat wire 20. The alkali-free glass cloth-impregnated epoxy resin plate is a plate structure formed by baking and pressing, has high strength, and is made of a softer material than the copper flat wire 20, so that the wire pressing plate 320, the first pressing plate 620 and the second pressing plate 630 are all made of the alkali-free glass cloth-impregnated epoxy resin plate, and the copper flat wire 20 is not easily worn when sliding in the wire pressing groove 310 and the wire guide groove 610, thereby being beneficial to improving the quality of the magnetic pole coil.
