Fig. 3 is a schematic diagram of the detailed structure of the stator insulating skeleton. As shown in FIG. 3 , one side of the inner mouthguard 1 has a winding support portion 11 and a slot insulating paper fixing block 12 . The slot insulating paper fixing block 12 protrudes from the supporting surface of the winding support part 11. Since the tangential swing angle of the winding action is fixed, the radial reciprocating action stroke cannot reach the first arc surface enveloping the outer surface of each slot insulating paper fixing block 12 The inner side of 120, that is, the part shown by the shadow in Figure 3, this part can only be filled and arranged by staying in the adjacent position and squeezing the coil. During this process, the radial reciprocating action stops, the state of the winding coil is unstable, and the winding is very easy Cross, loosen and wrap adjacent slot insulation.

detailed description

In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, features and effects of the application according to the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. . In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. Furthermore, the particular features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

As shown in FIG. 4 to FIG. 8 , an embodiment of the present invention proposes a stator insulating frame 100 , which includes an inner tooth guard 1 and a winding part 3 . The number of the inner mouthpiece 1 and the wire winding part 3 are equal and corresponding to each other. One end of the winding portion 3 is connected to the inner mouthguard 1 , and the other end is connected to the outer wall 2 of the stator insulating frame 100 . The number of inner mouthguards 1 is at least two. One side of each inner mouthguard 1 has a winding supporting portion 11 and at least two slot insulating paper fixing blocks 12 , and the slot insulating paper fixing blocks 12 are distributed on opposite sides of the winding supporting portion 11 . Wherein, in the outward direction along the radial direction of the stator insulating frame 100 , the winding support portion 11 is not lower than the first arc surface 120 , and each slot insulating paper fixing block 12 does not protrude from the first arc surface 120 . Wherein, the first arc surface 120 is a surface whose axis coincides with the axis of the stator insulating frame and has an overlapping area with the outer surface of each slot insulating paper fixing block 12 . The "coincident area" here may refer to a coincident point, or a coincident line, or a coincident surface, etc.

The above “not lower than” means that the winding support portion 11 may protrude from the first arc surface 120 in the radial direction outward of the stator insulating frame 100 , or be flush with the first arc surface 120 .

Further, along the axial direction of the stator insulating frame 100 , there is only one intersection point between the projected contour of the first arc surface 120 and the projected contour of the outer surface of each slot insulating paper fixing block 12 . Preferably: the above-mentioned first arc surface 120 may be a surface tangent to the outer surface of each slot insulating paper fixing block 12 . In a specific application example, as shown in FIG. 4 and FIG. 6 , the above-mentioned first arc surface 120 may be a cylindrical surface.

In the technical solution provided above, because the winding support portion 11 is not lower than the first arc surface 120 in the radially outward direction along the stator insulating frame 100, thereby avoiding the radial impact of the slot insulating paper fixing block 12 Winding interference, the winding radial reciprocating action of the winding machine can reach the winding support part 11 of the inner tooth guard 1, so that the radial reciprocating stroke of the winding machine is consistent with the actual radial arrangement stroke of the winding, and then The problem of coil crossing, loosening and coil wrapping groove insulation paper caused by the mismatch between the radial reciprocating action stroke of the winding and the radial arrangement stroke of the winding is improved.

Further, in the direction outward along the radial direction of the stator insulating frame 100 , the winding support portion 11 does not protrude from the first arc surface 120 and has a first area coincident with the first arc surface 120 . Wherein, the first area may be an arc surface extending along the circumferential direction of the stator insulating frame 100 (as shown in FIG. 5 and FIG. 8 ), or a straight line extending axially along the stator insulating frame 100 (as shown in FIG. 7 ). .

In the above example, as shown in Figure 5 and Figure 8, when the first area is an arc surface, the arc surface is a part of the cylindrical surface in the circumferential direction, and its surface area is relatively large, so the contact area with the winding is also large. Relatively large, the supporting effect on the winding is relatively good.

In the above example, as shown in FIG. 7 , when the first region is a straight line, its surface area is relatively small, so its volume is also small, and thus less material is consumed and the cost is lower.

Further, as shown in FIG. 5 and FIG. 7 , the aforementioned at least two slot insulating paper fixing blocks 12 located on the same inner mouthguard 1 include a first slot insulating paper fixing block 121 located on the first side of the winding support part 11 , and the second slot insulating paper fixing block 122 located on the second side of the winding support portion 11 . The first side is opposite the second side. Wherein, there is a first gap 1211 between the first side of the winding support part 11 and the first slot insulating paper fixing block 121; and/or, between the second side of the winding supporting part 11 and the second slot insulating paper fixing block 122 There is a second gap 1221 . In this example, by setting the first gap 1211 and the second gap 1221 , the material of the winding support part 11 can be saved and the cost can be saved.

Preferably, both the aforementioned first gap 1211 and the second gap 1221 exist, and at this time, the winding support part 11 is like a convex hump arranged on the inner mouthguard 1 , which can save cost to the greatest extent.

Wherein, further, when both the first gap 1211 and the second gap 1221 exist, the projection contour of the winding support part 11 along the axial direction of the stator insulating frame 100 does not protrude from the direction of the winding part 3 along the axial direction of the stator insulating frame 100 The profile is projected so that the winding support part 11 can strongly support the winding on the winding part 3 .

Of course, in an alternative example, as shown in FIG. 8 , neither the aforementioned first gap 1211 nor the second gap 1221 may exist. At this time, the first side of the winding support portion 11 extends to the first slot insulating paper fixing block. 121. The second side of the winding support part 11 extends to the second slot insulating paper fixing block 122 . In this example, since the two sides of the winding support part 11 respectively extend to the first slot insulating paper fixing block 121 and the second slot insulating paper fixing block 122, the supporting area of the winding supporting part 11 for the winding is relatively large, so that The support effect of the winding is relatively good.

The first side of the aforementioned winding support portion 11 can have a shape that matches the first slot insulating paper fixing block 121, which can enhance the strength of the stator insulating frame 100 of the present invention on the one hand, and improve the appearance on the other hand.

The second side of the aforementioned winding support portion 11 can have a shape suitable for the second groove insulating paper fixing block 122, which can enhance the strength of the stator insulating frame 100 of the present invention on the one hand, and improve the appearance on the other hand.

Further, as shown in FIG. 9 , in the axial direction along the stator insulating frame 100 , the height of the inner tooth guard 1 and the winding support portion 11 protruding from the winding portion 3 is smaller than that of the outer wall 2 of the stator insulating frame 100 . The height H1 of the winding part 3. Among them, due to the reduction of the height, on the one hand, the height of the coil falling in the axial direction during the winding process is reduced, and the problems of coil crossing, looseness, and coil wrapping groove insulation paper caused by the high coil drop height during the winding process are improved; On the other hand, the inner guard 1 will have a radial displacement towards the inner hole of the stator insulating frame 100 under the action of winding tension load. This physical process is simplified to the deflection of the cantilever beam under load, and the maximum deflection is at the top of the cantilever. That is, the maximum radial displacement position of the inner mouthguard 1 is at its top. Due to the reduction of the height, under the premise of the same winding scheme and tension force, according to the characteristics of the deflection of the cantilever beam under load, the maximum displacement of the inner guard 1 of the insulating frame towards the inner hole of the stator insulating frame 100 will be reduced, that is, the inner The radial safety distance of the mouthguard 1 is increased, which improves the problem of the inner hole of the stator insulating frame 100 in the inner mouthguard 1 .

As shown in FIGS. 4 to 8 , the stator insulating frame 100 of the present invention includes a stator slot 4 , and the stator slot 4 has a notch 41 . There is a first intersection line between the aforementioned first arc surface 120 and the first plane 13 . The first plane 13 is parallel to the second plane. The second plane bisects the width of the slot and passes through the center line of the stator insulating frame 100 . The "passing" here means that the central line of the sub-insulation frame 100 is located on the second plane. The distance between the above-mentioned first plane 13 and the second plane is half of the width of the notch 41 .

The side of the aforementioned wire winding portion 3 close to the first intersection line has a third plane 31 constituting part of the slot wall of the stator slot 4 , and the distance between the first intersection line and the third plane 31 is h. Wherein, in the axial direction along the stator insulating frame 100, the heights of the protruding winding portion 3 of the inner tooth guard 1 and the winding support portion 11 are equal and greater than or equal to h. As shown in FIG. 9 , both the inner mouthguard 1 and the winding support portion 11 protrude from the winding portion 3 to a height of H2, and H2 must be greater than or equal to h and less than H1. Preferably, the height H2 of both the inner mouthguard 1 and the winding support part 11 protruding from the winding part 3 is equal to h. In this example, h is the limit height of the winding arrangement on the winding part 3, by reducing the height H2 to h of both the inner guard 1 and the winding support part 11, the coil edge during the winding process can be minimized. The height of the axial drop can further improve the problems of coil crossing, looseness, and insulation paper in the coil wrapping groove caused by the large drop height of the coil during the winding process.

As shown in FIG. 10 and FIG. 11 , an embodiment of the present invention further provides a stator assembly 200, which includes the stator insulating frame 100 in any of the above-mentioned embodiments. The stator assembly 200 provided by the present invention can also improve the coil intersecting, looseness and coil wrapping slot insulation caused by the discrepancy between the radial reciprocating action stroke of the winding and the radial arrangement stroke of the winding due to the above-mentioned stator insulating skeleton 100. paper etc.

Embodiments of the present invention also provide a motor, which includes the stator insulation frame 100 in any of the above embodiments. Because the motor provided by the present invention is provided with the above-mentioned stator insulating frame 100, it can also improve the coil crossing, loosening and coil wrapping groove insulation paper caused by the mismatch between the radial reciprocating action stroke of the winding and the radial arrangement stroke of the winding. question.

The working principle and preferred embodiments of the present invention will be introduced below.

The technical solution provided above solves the following technical problems: (1) the technical problem of mismatching axial reciprocating strokes; (2) the technical problem of mismatching radial reciprocating strokes; Technical issues with bores.

1. Improvement of mismatch of axial reciprocating stroke:

As shown in Figure 5, Figure 7 and Figure 8, there is a first intersection line between the first arc surface 120 and the first plane 13, wherein the first plane 13 is the theoretical limit of the coil tangential arrangement, and the winding part The side of 3 close to the first intersection line has a third plane 31 forming part of the slot wall of the stator slot 4 . The distance between the above-mentioned first intersection line and the third plane 31 is h, and h is the limit height of the windings arranged on the stator insulating frame 100 . The axial height of the corresponding part of the mouthguard 1 in the current scheme is much higher than this value, resulting in the winding axial reciprocating stroke Hn being greater than the winding axial arrangement stroke Hc (as shown in Figure 2). During the winding process, the winding coil moves from The height of Hn is reduced to Hc, and the drop is large. During the high-speed winding process, the swing amplitude of the coil is therefore enlarged, and the coil arrangement is unstable, which may easily cause problems such as crossover, looseness, and insulation paper in the coil wrapping groove.

As shown in Figure 9, since H2 is equal to the aforementioned h, Hn=Hc, that is, the axial reciprocating stroke of the winding coincides with the axial arrangement stroke of the winding, which reduces the height of the coil falling during the winding process, thereby improving Due to the high drop height of the coil during the winding process, there are problems such as coil crossing, looseness, and insulation paper in the coil wrapping groove.

2. The improvement of radial reciprocating stroke mismatch:

As shown in Figure 3, the first arc surface 120 in the current scheme does not coincide with the support surface of the winding support part 11, and the radial reciprocating stroke of the shadowed part of the winding cannot be reached. Line, that is, the radial reciprocating action stroke does not match the actual radial arrangement stroke of the winding. The stagnant winding action of the non-matching part of the stroke makes the state of the winding coil near this place extremely unstable, and it is easy to cause the coils to cross and loose, and the loose coils are easy to wrap the insulating paper of the adjacent slot.

Solution 1, as shown in Figure 5, the first arc surface 120 of the present invention coincides with the support surface of the winding support part 11, or is within the support surface of the winding support part 11 (that is, the entire support surface of the winding support part 11 Add glue until it coincides with the first arc surface 120 or protrudes from the first arc surface 120). At this time, the interference of the slot insulating paper fixing block 12 is avoided, and the radial reciprocating action of the winding can reach the support surface of the winding support part 11. The radial reciprocating stroke coincides with the actual radial arrangement stroke of the winding, which improves the problems of coil crossing, loosening and coil wrapping groove insulation paper caused by the mismatch between the radial reciprocating movement stroke of the winding and the radial arrangement stroke of the winding.

Solution 2, as shown in Figure 7, add glue to the support surface of the winding support part 11 to form a protrusion, so that the first arc surface 120 overlaps or includes it, so that the radial reciprocating action stroke of the winding is in line with the radial arrangement of the winding Cloth travel coincidence, winding quality is improved.

Solution 3, as shown in Figure 8, add glue to the support surface of the winding support part 11 to coincide with or include the first arc surface 120, and at the same time extend both sides to the slot insulating paper fixing block 12, so that the winding radially reciprocates The action stroke coincides with the winding radial arrangement stroke, and the winding quality is improved.

3. Improvement of the inner hole of the super-stator insulating framework 100 in the inner mouthguard 1 .

The inner guard 1 will have a radial displacement towards the inner hole of the stator insulating frame 100 under the action of winding tension load. This physical process is simplified to the deflection of the cantilever beam under load, and the maximum deflection is at the top of the cantilever. That is, the maximum radial displacement position of the inner mouthguard 1 is at its top.

The axial height of the inner guard 1 of the stator insulating frame 100 of the present invention is reduced. Under the premise that the winding scheme and the tension force remain unchanged, the inner guard 1 faces the inner hole of the stator insulating frame 100 according to the characteristics of the deflection of the cantilever beam under load. The maximum displacement of the inner tooth guard 1 will be reduced, that is, the radial safety distance of the inner tooth guard 1 is increased, which improves the problem of the inner hole of the super stator insulating skeleton 100 in the inner tooth guard 1 .

According to the above embodiments, the stator insulating frame 100, the stator assembly and the motor of the present invention have at least the following advantages:

1. The stator insulating frame 100 of the present invention optimizes the height and profile of the inner tooth guard 1 according to the actual shape of the coil, the axial reciprocating stroke of the winding action is more consistent with the actual radial arrangement stroke of the coil, the winding action is smoother, and the winding arrangement is improved Effect;

2. The stator insulating frame 100 of the present invention optimizes the radial structure of the inner tooth guard 1, removes the dead angle that cannot be reached by the winding stroke, and the radial stroke of the winding action is consistent with the actual arrangement of the winding, eliminating the need to stay in place for the winding action , Remove the main reasons for the problems of loose coils, loose coils and grooves from the root;

3. The axial height of the inner tooth guard 1 of the stator insulating frame 100 of the present invention is reduced, and under the same winding scheme and tension force, the maximum displacement of the radial deformation of the inner tooth guard 1 can be effectively reduced, and the inner overshoot of the inner tooth guard 1 can be reduced. The risk of bores in the stator insulating frame 100 .

What needs to be explained here is: in the case of no conflict, those skilled in the art can combine the relevant technical features in the above examples according to the actual situation to achieve the corresponding technical effect. Let me repeat them one by one.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still belong to the present invention. within the scope of the technical solution of the invention.
