Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A stator 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 10, and the stator 100 may be assembled to a motor.
As shown in fig. 1 to 3, a stator 100 according to an embodiment of the present invention may include: stator core 1, insulating cylinder 2, mounting point 3, stator winding 4 and a plurality of crashproof lugs 5. Wherein the mounting point 3 is adapted to mount a seat spring, thereby facilitating the connection of the movement of the compressor to the casing of the compressor through the seat spring 200 when the stator 100 is assembled to the motor and the motor is assembled to the compressor.
Specifically, as shown in fig. 1 to 3, the insulating cylinder 2 and the mounting points 3 are provided on an end face of one axial end of the stator core 1. As shown in fig. 10, the insulating cylinder 2 includes a placement portion 21 and a mounting portion 22, the placement portion 21 is provided on the mounting portion 22, the plurality of mounting points 3 are located outside the placement portion 21, that is, the insulating cylinder 2 and the mounting points 3 are provided on an end surface of one end of the stator core 1 in the axial direction, and the plurality of mounting points 3 are surrounded outside the insulating cylinder 2. Alternatively, a plurality of mounting points 3 are provided around the insulating cylinder 2 at even intervals in the circumferential direction of the insulating cylinder 2. For example, as shown in fig. 1 to 3, the number of the mounting points 3 is four, i.e., a first mounting point 3a to a fourth mounting point 3d, and the four mounting points 3 are provided around the insulator cylinder 2 at even intervals in the circumferential direction of the insulator cylinder 2.
The cross section of the stator core 1 is in a ring shape, a plurality of stator teeth arranged at intervals are formed on the inner peripheral wall of the stator core 1, the stator winding 4 is wound on the stator teeth of the stator core 1, and a plurality of winding wires 41 of the stator winding 4 are wound on the outer peripheral wall of the placing part 21 through a wire passing hole 213 arranged on the placing part 21, as shown in fig. 5 and 10.
Here, it is understood that the number of the windings 41 of the stator winding 4 is related to the number of phases of the motor, and for example, as shown in fig. 4 to 6, when the motor is a three-phase motor, the number of the windings 41 of the stator winding 4 is three, that is, the first winding 41a, the second winding 41b, and the third winding 41 c.
A plurality of the bump projections 5 are provided at intervals on the outer peripheral wall of the placement portion 21, and for example, as shown in fig. 1 to 3, three bump projections 5 (i.e., first to third bump projections 5a to 5c) are provided at intervals on the outer peripheral wall of the placement portion 21.
Each winding 41 is correspondingly provided with at least one bump 5 which is opposite to the mounting point 3 in the radial direction, for example, the first winding 41a is correspondingly provided with one bump 5 which is opposite to the mounting point 3 in the radial direction, the second winding 41b is correspondingly provided with two bumps 5 which are opposite to the mounting point 3 in the radial direction, and the third winding 41c is correspondingly provided with two bumps 5 which are opposite to the mounting point 3 in the radial direction.
The peripheral wall of the bump 5 extends beyond the winding 41, and therefore, when the stator 100 is used on the motor and the motor is assembled on the compressor, under the condition that the compressor shakes, the setting of the bump 5 can ensure that the seat spring and the winding 41 are not in direct contact, thereby avoiding the damage of the winding 41 and ensuring the safety and reliability of the compressor.
According to the stator 100 of the embodiment of the invention, the plurality of the bump guards 5 are arranged on the outer peripheral wall of the placing part 21 at intervals, and the outer peripheral walls of the bump guards 5 extend beyond the winding 41, so that when the stator 100 is used on a motor and the motor is assembled on a compressor, the bump guards 5 can ensure that the seat spring is not in direct contact with the winding 41 even if the compressor shakes, thereby avoiding the damage of the winding 41 and ensuring the safety and reliability of the compressor.
In some embodiments of the present invention, as shown in fig. 4 to 9, a plurality of placing protrusions 211 are provided on the outer circumferential wall of the placing portion 21, and at least one placing protrusion 211 is provided below each bump 5 to define a wire passing groove 212 of the corresponding wire 41. For example, as shown in fig. 4 and 7, a wire passing groove 212 for passing the first winding wire 41a is defined between the placing lug 211 below the first bump 5a and the first bump 5 a; as shown in fig. 5 and 8, a wire passing groove 212 for passing the second wire 41b is defined between the placing lug 211 below the second bump 5b and the second bump 5 b; as shown in fig. 6 and 9, a wire passing groove 212 for passing the third winding wire 41c is defined between the placing projection 211 below the third bump 5c and the third bump 5 c. Thus, the winding wire 41 of the stator winding 4 can pass through the wire passing groove 212 when being wound on the outer peripheral wall of the placement portion 21 so as to facilitate the fixation and the limitation of the winding wire 41 by the wire passing groove 212, avoiding the displacement of the winding wire 41.
Specifically, as shown in fig. 7 to 9, the placement projections 211 are arranged to be staggered in the axial direction with respect to the corresponding bump 5. Thus, the structure is simple.
Optionally, as shown in fig. 7 to 9, a value of the height L1 of the wire passing groove 212 in the axial direction ranges from 1.5mm to 2 mm. Therefore, on one hand, the seat spring 200 can be prevented from being clamped into the wire passing groove 212 to damage the winding 41 in the shaking process of the compressor, on the other hand, the winding 41 can be conveniently and smoothly assembled into the wire passing groove 212, and the winding 41 has enough tension. Alternatively, L1 is 1.8 mm.
In some embodiments of the present invention, the tip of the bump 5 corresponding to the uppermost winding wire 41 extends beyond the tip surface of the placement portion 21. For example, as shown in fig. 4 and 7, the first winding 41a is the uppermost winding 41, and the tip of the first bump 5a corresponding to the first winding 41a extends beyond the tip surface of the placement unit 21. Thus, the bump 5 can prevent the wall of the insulating cylinder 2 from being broken due to the impact of the seat spring 200 while blocking the contact between the seat spring 200 and the winding 41.
Specifically, as shown in fig. 7, the distance H between the tip end surface of the bump 5 and the tip end surface of the placement portion 21 ranges from 1.4mm to 1.6 mm. For example, H is 1.47, 1.56 mm.
In some embodiments of the present invention, the tip end surfaces of the bump 5 corresponding to the remaining windings 41 excluding the winding 41 located uppermost are flush with the tip end surface of the placement portion 21. For example, as shown in fig. 5 to 6 and 8 to 9, the first winding 41a is the uppermost winding 41, the second winding 41b and the third winding 41c are located below the first winding 41a, and the top end surfaces of the second bump 5b corresponding to the second winding 41b and the third bump 5c corresponding to the third winding 41c are flush with the top end surface of the placement portion 21. Thus, the structure is simple.
Alternatively, the peripheral walls of the plurality of crash projections 5 lie on the same circle. Therefore, the structure is simple, and the structure of the stator 100 is optimized.
In some embodiments of the present invention, a circle with a radius R of 15mm and each mounting point 3 as a center of a circle is used as a trajectory circle of the corresponding mounting point 3, and an orthogonal projection of the bump 5, which is disposed opposite to each mounting point 3, in the axial direction of the stator core 1 is located within the trajectory circle of the corresponding mounting point 3. For example, as shown in FIG. 3, a circle having a radius R of 15mm with the first mounting point 3a as the center is a locus circle of the first mounting point 3a, the orthographic projection of the first bump-prevention projection 5a which is arranged opposite to the first mounting point 3a in the axial direction of the stator core 1 is positioned in the locus circle of the first mounting point 3a, a circle with the second mounting point 3b as the center and the radius R of 15mm is taken as the locus circle of the second mounting point 3b, the orthographic projection of the second bump-prevention projection 5b which is arranged opposite to the second mounting point 3b in the axial direction of the stator core 1 is positioned in a locus circle of the second mounting point 3b, a circle with the third mounting point 3c as the center and the radius R of 15mm is taken as the locus circle of the third mounting point 3c, the orthographic projection of the third collision-prevention bump 5c arranged just opposite to the third mounting point 3c in the axial direction of the stator core 1 is located within the locus circle of the third mounting point 3 c. This facilitates optimizing the distance between the mounting point 3 and the bump 5, and thus optimizing the structure of the stator 100.
The structure of the stator 100 according to one embodiment of the present invention will be described in detail with reference to fig. 1 to 10.
As shown in fig. 1 to 3, a stator 100 of an embodiment of the present invention includes: the stator winding comprises a stator core 1, an insulating cylinder 2, four mounting points 3 (namely a first mounting point 3a to a fourth mounting point 3d), three bump lugs 5 (namely a first bump lug 5a, a second bump lug 5b and a third bump lug 5c) and a stator winding 4. Wherein mounting point 3 is adapted to mount seat spring 200, thereby facilitating the connection of the movement of the compressor to the casing of the compressor through seat spring 200, when stator 100 is assembled to the motor and the motor is used in the compressor.
The cross section of stator core 1 is annular shape, forms a plurality of stator teeth that set up at interval on the internal perisporium of stator core 1, and stator winding 4 twines on stator teeth of stator core 1.
Specifically, the insulating cylinder 2 and the mounting points 3 are provided on an end face of one axial end of the stator core 1. As shown in fig. 10, the insulating cylindrical body 2 includes a placement portion 21 and a mounting portion 22, the placement portion 21 is provided on the mounting portion 22, four mounting points 3 are located outside the placement portion 21 and the four mounting points 3 are provided around the placement portion 21 at even intervals in the circumferential direction of the insulating cylindrical body 2. The three windings 41 of the stator winding 4 (i.e., the first, second, and third windings 41a, 41b, and 41c) are wound on the outer peripheral wall of the placement portion 21 through the wire passing holes 213 provided on the placement portion 21.
Three bump tabs 5 are provided on the outer peripheral wall of the placement portion 21 at intervals. First wire 41a corresponds the setting with first bump lug 5a, and first bump lug 5a just directly faces the setting with first mounting point 3a in the footpath, second wire 41b corresponds the setting with first bump lug 5a and second bump lug 5b respectively, and second bump lug 5b just faces the setting with second mounting point 3b, third wire 41c corresponds the setting with second bump lug 5b and third bump lug 5c respectively, and the third bump lug 5c just faces the setting with third mounting point 3c, every bump lug 5's periphery wall extends and surpasss the wire. Thus, the first bump 5a may block the first and second windings 41a and 41b from the seat spring 200 mounted on the first mounting point 3a, the second bump 5b may block the second and third windings 41b and 41c from the seat spring 200 mounted on the second mounting point 3b, and the third bump 5c may block the third winding 41c from the seat spring 200 mounted on the third mounting point 3 c. From this, under the condition that compressor core rocked, the setting of anticollision lug 5 can guarantee that seat spring and wire winding 41 are direct contact not to avoid wire winding 41's damage, guaranteed the security and the reliability of compressor.
And a circle with each mounting point 3 as the center and the radius R of 15mm is taken as a track circle of the mounting point 3. Specifically, a circle with a first mounting point 3a as a center of circle and a radius R of 15mm is used as a trajectory circle of the first mounting point 3a, an orthographic projection of a first bump 5a, which is arranged just opposite to the first mounting point 3a, in the axial direction of the stator core 1 is located in the trajectory circle of the first mounting point 3a, a circle with a second mounting point 3b as a center of circle and a radius R of 15mm is used as a trajectory circle of the second mounting point 3b, an orthographic projection of a second bump 5b, which is arranged just opposite to the second mounting point 3b, in the axial direction of the stator core 1 is located in the trajectory circle of the second mounting point 3b, a circle with a third mounting point 3c as a center of circle and a radius R of 15mm is used as a trajectory circle of the third mounting point 3c, and an orthographic projection of a third bump 5c, which is arranged just opposite to the third mounting point 3c, in the axial direction of the stator core 1 is.
The outer peripheral wall of the placing portion 21 is provided with a plurality of placing protrusions 211, and one placing protrusion 211 is disposed below each bump 5 to define a wire passing groove 212 of the corresponding wire 41. Specifically, as shown in fig. 4 to 6, the first bump 5a and the placing bump 211 located below the first bump define a wire passing groove 212 of the first winding 41a, the first bump 5a and the corresponding placing bump 211 are arranged alternately in the axial direction, the second bump 5b and the placing bump 211 located below the second bump define a wire passing groove 212 of the second winding 41b, the second bump 5b and the corresponding placing bump 211 are arranged alternately in the axial direction, the third bump 5c and the placing bump 211 located below the third bump define a wire passing groove 212 of the third winding 41c, and the third bump 5c and the corresponding placing bump 211 are arranged alternately in the axial direction.
As shown in fig. 7-9, the height L1 of the wire passing groove 212 in the axial direction ranges from 1.5mm to 2 mm. Therefore, on one hand, the seat spring can be prevented from being clamped into the wire passing groove 212 to damage the winding 41 in the shaking process of the compressor, on the other hand, the winding 41 can be conveniently and smoothly assembled into the wire passing groove 212, and the winding 41 has enough tension.

The tip of the first bump 5a corresponding to the uppermost first winding 41a extends beyond the tip surface of the placement portion 21. In this way, it is ensured that the first bump 5a serves to block the contact between the seat spring 200 and the first winding 41a, and it is possible to prevent the wall of the insulating cylinder 2 from being broken due to the impact of the seat spring 200.
Specifically, the distance H between the tip end surface of the first bump 5a and the tip end surface of the placement portion 21 ranges from 1.4mm to 1.6 mm. The tip end surfaces of the second bump 5b corresponding to the second winding 41b and the third bump 5c corresponding to the third winding 41c are flush with the tip end surface of the placement portion 21, except for the uppermost first winding 41 a.
