Description

[0002] The motor stator is the fixed part of the motor, corresponding to the rotating motor rotor. The main function of the motor stator is to generate a rotating magnetic field, which interacts with the rotor to make the rotor rotate and output mechanical energy.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] like Figure 1 and Figure 2 As shown, in order to achieve the above-mentioned purpose, the present invention provides a motor stator, including: a stator bracket 1 and a common terminal plate 4 and a phase line terminal plate 5 arranged on the stator bracket 1.

[0037] Among them, the stator winding 2 is arranged on the outer peripheral side of the stator bracket 1, and the stator winding 2 is used to wind the copper wire 3, which is a relatively mature existing technology, so it is not described in detail. It should be noted that the end face of the stator bracket 1 is provided with a common terminal plate 4, and the top surface of the common terminal plate 4 is provided with a star-shaped piece 6, and the star-shaped piece 6 is used to connect the common terminal 7 of the copper wire 3. Preferably, the star-shaped piece 6 is connected to the common terminal 7 of the copper wire 3 by soldering.

[0038] A phase terminal disk 5 is provided on the end face of the stator bracket 1, and the phase terminal disk 5 and the common terminal disk 4 are provided on the end face of the same end of the stator bracket 1. A terminal connecting portion 8 is provided on the top face of the phase terminal disk 5, and a first phase terminal portion 9 and a second phase terminal portion 10 of the copper wire 3 are connected through the terminal connecting portion 8, and a common terminal 7 of the copper wire 3 is connected through a star-shaped piece 6 on the common terminal disk 4, so that the common terminal 7 of the copper wire 3 and the phase terminal of the copper wire 3 are directly positioned on the wiring disk, and there is no need to manually continue to wind the wound copper wire 3 on the upper side of the stator winding 2, so that the assembly of the overall motor stator is more organized and convenient for realizing automated assembly.

[0039] It should be further explained that, since the wound copper wire 3 is no longer manually wound on the upper side of the stator winding 2, the assembly efficiency of the motor stator can be improved, and the longitudinal length of the stator winding 2 is reduced, making the motor smaller. In addition, the copper wire 3 is no longer wound on the upper side of the stator winding 2, which is beneficial to the heat dissipation of the motor stator and improves the overall performance of the motor.

[0040] During assembly, the common terminal plate 4 is fixed on the stator bracket 1, the star-shaped piece 6 is fixed on the top surface of the common terminal plate 4, the star-shaped piece 6 is connected to the common terminal 7 of the copper wire 3, and then the phase terminal plate 5 is fixed on the stator bracket 1, the terminal connecting part 8 is fixed on the top surface of the phase terminal plate 5, and the first phase terminal part 9 and the second phase terminal part 10 of the copper wire 3 are connected through the terminal connecting part 8 to complete the assembly of the motor stator. During assembly, there is no need to manually continue to wind the wound copper wire 3 on the upper side of the stator winding 2, so that the assembly of the overall motor stator is more organized, and the longitudinal length of the stator winding 2 is reduced, making the motor smaller.

[0041] like Figure 3 , Figure 5 and Figure 7 As shown, the wiring board is split into a common terminal board 4 and a phase terminal board 5, which is conducive to the assembly of the wiring board on the stator bracket 1.

Specifically, a plurality of notches 14 are arranged in an array on the top surface of the phase terminal board 5, and the common terminal board 4 is installed at the position of the notch 14. The notch 14 cooperates with the common terminal board 4 to enhance the stability of the overall wiring board. Of course, according to needs, the phase terminal board 5 and the common terminal board 4 can also be integrally formed, and the wiring board can be assembled as a whole.

[0042] In addition, a bayonet 16 is provided on the side of the common terminal disk 4, and a pressure block 15 is provided on the side of the notch 14. Specifically, two pressure blocks 15 are symmetrically provided on the side of the notch 14, and each pressure block 15 is connected to a bayonet 16. During assembly, after the common terminal disk 4 is fixed to the end face of the stator bracket 1 by the fourth screw, the phase terminal disk 5 is placed on the end face of the stator bracket 1, and the pressure block 15 enters the bayonet 16. After the fifth screw passes through the bayonet 16 and the pressure block 15, the stator bracket 1 is threadedly connected, and the common terminal disk 4 and the phase terminal disk 5 are fixed to the end face of the stator bracket 1 at the same time. The common terminal disk 4 and the phase terminal disk 5 are more accurately docked during assembly, and the overall connection strength of the common terminal disk 4 and the phase terminal disk 5 on the stator bracket 1 can be enhanced.

A fourth U-shaped part 601 is arranged at the end of each metal connecting plate. The fourth U-shaped part 601 is respectively connected to the common terminal 7 of the copper wire 3 by soldering. In addition, a first limiting groove is arranged on the top surface of the common terminal disk 4. The star-shaped part 6 is located in the first limiting groove to ensure that the star-shaped part 6 is stably fixed on the top surface of the common terminal disk 4. A first mounting hole is arranged on the top surface of the star-shaped part 6. The common terminal disk 4 is threadedly connected by a second screw passing through the first mounting hole to fix the star-shaped part 6 on the top surface of the common terminal disk 4.

[0048] In addition, insulating partitions 807 are provided between the first copper sheet 801 and the second copper sheet 802, and between the second copper sheet 802 and the third copper sheet 803. The insulating partitions 807 isolate the first copper sheet 801, the second copper sheet 802 and the third copper sheet 803 from each other to form insulation, so as to ensure that the first copper sheet 801, the second copper sheet 802 and the third copper sheet 803 can work stably and independently.

[0049] In one embodiment of the present invention, a plurality of first assembly holes 501 are provided on the top surface of the phase terminal plate 5, and the plurality of first assembly holes 501 are respectively located at the two ends of the first copper sheet 801, the two ends of the second copper sheet 802, and the two ends of the third copper sheet 803, so as to facilitate soldering of the first U-shaped part 804, the second U-shaped part 805, and the third U-shaped part 806. Among them, a blocking block 19 is provided at the position of each first assembly hole 501. After the welding of the first U-shaped part 804, the second U-shaped part 805 and the third U-shaped part 806 is completed, the first assembly hole 501 is blocked by the blocking part, and glue is applied at the soldering position of the first U-shaped part 804, the second U-shaped part 805 and the third U-shaped part 806, and the first U-shaped part 804, the second U-shaped part 805 and the third U-shaped part 806 are respectively fixed on the corresponding blocking block 19, so as to further enhance the stability of the first U-shaped part 804 connected to the first phase line terminal part 9, the stability of the second U-shaped part 805 connected to the second phase line terminal part 10, and the stability of the third U-shaped part 806 connected to each motor terminal 11.

[0050] It should be noted that the second U-shaped part 805 and the third U-shaped part 806 are jointly arranged at the same end of the terminal connecting part 8, and the second U-shaped part 805 and the third U-shaped part 806 are arranged close to each other, and the assembly holes below the second U-shaped part 805 and the third U-shaped part 806 are set as waist-shaped holes to ensure that the corresponding blocking block 19 stably connects the second U-shaped part 805 and the third U-shaped part 806.

[0051] At the same time, a plurality of second assembly holes 401 are arranged on the top surface of the common terminal plate 4, and the plurality of second assembly holes 401 are respectively located at the ends of the metal connecting sheet, so as to facilitate soldering of the fourth U-shaped member 601.

After the fourth U-shaped member 601 is welded, the second assembly hole 401 is blocked by the blocking block, and glue is applied at the soldering position of the fourth U-shaped member 601 to fix the fourth U-shaped member 601 on the corresponding blocking block 19, so as to enhance the stability of the connection between the fourth U-shaped member 601 and the motor terminal 11.

[0052] In addition, a plurality of through slots 17 are provided on the top surface of the phase terminal plate 5 , each through slot 17 communicating with a first assembly hole 501 and the recessed groove 12 , thereby enabling the terminal connecting portion 8 to smoothly connect the first phase terminal portion 9 and the second phase terminal portion 10 .

[0053] In one embodiment of the present invention, a first positioning hole is provided on the bottom surface of the through groove 17, and second positioning holes are provided at both ends of the first copper sheet 801, both ends of the second copper sheet 802, and both ends of the third copper sheet 803. A third screw is passed through the second positioning holes to connect the first positioning holes, and the two ends of the first copper sheet 801, the two ends of the second copper sheet 802, and the two ends of the third copper sheet 803 are respectively fixed in the through groove 17.

[0054] Furthermore, first bending sections 18 are provided at both ends of the second copper sheet 802, and the first bending sections 18 extend upward from the middle of the second copper sheet 802 to both ends of the second copper sheet 802. Second bending sections 21 are provided at both ends of the third copper sheet 803, and the second bending sections 21 extend upward from the middle of the third copper sheet 803 to both ends of the third copper sheet 803, so that both ends of the first copper sheet 801, both ends of the second copper sheet 802, and both ends of the third copper sheet 803 are located in the same plane, which facilitates the connection of the first copper sheet 801, the second copper sheet 802, and the third copper sheet 803 to the first phase line terminal portion 9 and the second phase line terminal portion 10, thereby improving assembly efficiency and improving the overall appearance of the material receiving tray.

[0055] At the same time, a first inclined surface is set in the through slot 17 matched with the second copper sheet 802, and the first inclined surface is fitted with the bottom surface of the first bending section 18. A second inclined surface is set in the through slot 17 matched with the third copper sheet 803, and the second inclined surface is fitted with the bottom surface of the second bending section 21, thereby ensuring that the first copper sheet 801 and the second copper sheet 802 are stably assembled in the through slot 17.

Specifically, an annular protrusion 101 is provided on the end surface of the stator bracket 1 close to the common terminal plate 4, and a plurality of grooves 102 are arranged in an array on the end surface of the annular protrusion 101. An extension portion 1301 is provided on the inner peripheral side surface of the pressing plate 13. When the bottom surface of the pressing plate 13 is in contact with the top surface of the stator winding 2, the extension portion 1301 enters the groove 102. A second threaded hole is provided on the bottom surface of the groove 102, and a through hole is provided on the top surface of the extension portion 1301. The first screw passes through the through hole and connects to the second threaded hole to fix the pressing plate 13 on the positioning bracket.

[0057] It should be noted that the pressing plate 13 is in the shape of a closed ring as a whole, and the top surface of the pressing plate 13 does not exceed the end surface of the stator bracket 1 close to the common terminal plate 4, so as to ensure that the setting of the pressing plate 13 does not affect the overall longitudinal size of the motor stator. On the other hand, the phase terminal plate 5 and the common terminal plate 4 completely cover the pressing plate 13, and at the same time, the first phase terminal portion 9 and the second phase terminal portion 10 of the copper wire 3 are located on the upper side of the phase terminal plate 5, and the common terminal 7 of the copper wire 3 is located on the upper side of the common terminal plate 4, thereby forming insulation for the first phase terminal portion 9 and the second phase terminal portion 10 of the copper wire 3 and the common terminal 7 of the copper wire 3, thereby improving the stability of the motor stator during operation.

[0058] like Figure 4 and Fig.11 As shown, a plurality of receiving grooves 20 are arranged in an array on the bottom surface of the common terminal disk 4 and the bottom surface of the phase terminal disk 5, and each receiving groove 20 is adapted to a first screw. When the phase terminal disk 5 and the common terminal disk 4 completely cover the pressure plate 13, the upper end of the first screw is prevented from lifting the phase terminal disk 5 and the common terminal disk 4, thereby further avoiding affecting the overall longitudinal dimension of the motor stator.

[0059] When the present invention is used, the common terminal plate 4 is fixed on the stator bracket 1, the star-shaped piece 6 is fixed on the top surface of the common terminal plate 4, the common terminal 7 of the copper wire 3 is connected through the star-shaped piece 6, and then the phase terminal plate 5 is fixed on the stator bracket 1, the pressing block 15 enters the bayonet 16, and the fifth screw passes through the bayonet 16 and the pressing block 15 and then is threadedly connected to the stator bracket 1, and the common terminal plate 4 and the phase terminal plate 5 are simultaneously fixed on the end surface of the stator bracket 1, and the first copper sheet 801, the second copper sheet 802 and the third copper sheet 803 are screwed from the top. From bottom to top, they are sequentially arranged in the recessed groove 12 on the top surface of the phase terminal disk 5, and the two ends of the first copper sheet 801, the two ends of the second copper sheet 802 and the two ends of the third copper sheet 803 are respectively fixed in the through groove 17 by the third screw. The first copper sheet 801 connects the first phase terminal 901 and the fourth phase terminal 1001, the second copper sheet 802 connects the second phase terminal 902 and the fifth phase terminal 1002, and the third copper sheet 803 connects the third phase terminal 903 and the sixth phase terminal 1003, thereby completing the assembly of the motor stator.

[0060] In summary, by directly positioning the common terminal 7 of the copper wire 3 and the first phase terminal part 9 and the second phase terminal part 10 of the copper wire 3 on the wiring board, there is no need to manually continue to wind the wound copper wire 3 on the upper side of the stator winding 2, which is beneficial to the heat dissipation of the motor stator, improves the overall performance of the motor, and makes the assembly of the overall motor stator more organized, effectively reduces the longitudinal length of the stator winding 2, and makes the motor smaller.

[0061] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0062] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the present invention.
