[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0025] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0026] Embodiment 1: As Figure 1 - Figure 4As shown, the utility model provides a high-efficiency motor stator, including an iron core ring seat 1, a plurality of groups of convex iron cores 11 are fixedly mounted on the outer wall of the iron core ring seat 1, the outer walls of the plurality of groups of convex iron cores 11 are all wound with stator windings 12, the outer walls of the plurality of groups of convex iron cores 11 are sleeved with a barrier ring 13, the outer wall of the barrier ring 13 is provided with a heat dissipation mechanism 2, and the other end of the heat dissipation mechanism 2 is provided with a fixing mechanism 3;

[0027] The heat dissipation mechanism 2 includes a heat dissipation circular ring block 21, the outer wall of which is provided with a plurality of groups of special-shaped heat dissipation grooves 23, a circular ring pad 22 is welded to one end of the heat dissipation circular ring block 21, the heat dissipation circular ring block 21 is sleeved on the outer wall of the partition circular ring 13, and one end of the iron core circular ring seat 1 is in contact with one end of the circular ring pad 22.

[0028] The specific setting and function of this embodiment are described in detail below. With the cooperation of several groups of convex iron cores 11 and several groups of stator windings 12, and the angle between every two adjacent convex iron cores 11 is 30 degrees, and then several groups of stator windings 12 are respectively wound on the outer walls of several groups of convex iron cores 11, sufficient gaps can be reserved between every two adjacent stator windings 12, thereby preventing several groups of stator windings 12 from being in close contact, thereby preventing heat from being transferred poorly between several groups of stator windings 12, facilitating heat transfer to the outside of the stator, preventing the temperature of certain parts of the stator from rising rapidly, and forming hot spots, thereby preventing the normal operation and life of the motor from being affected;

[0029] By providing the heat dissipation circular ring block 21, when the stator generates heat, the heat dissipation circular ring block 21 can absorb most of the generated heat and dissipate it outwards during rotation, thereby being able to dissipate the heat generated by the stator and prevent the stator from being damaged by the heat. The opening of a plurality of groups of special-shaped heat dissipation grooves 23 can speed up the discharge of heat on the surface of the heat dissipation circular ring block 21 and prevent the heat from being dissipated slowly on the surface of the heat dissipation circular ring block 21, thereby affecting the heat absorption of the heat dissipation circular ring block 21.

[0030] By setting a partition ring 13, the outer wall of several groups of convex iron cores 11 and the inner wall of the heat dissipation ring block 21 can be blocked to prevent wear between the heat dissipation ring block 21 and several groups of convex iron cores 11, and the heat dissipation ring block 21 and several groups of convex iron cores 11 can be protected to improve the service life of the heat dissipation ring block 21 and several groups of convex iron cores 11. The setting of the ring pad 22 makes it convenient for the ring pad 22 to block the iron core ring seat 1 when the iron core ring seat 1 is placed into the interior of the heat dissipation ring block 21, so as to have a blocking effect on one end of the heat dissipation ring block 21 and prevent the iron core ring seat 1 from moving out of the interior of the heat dissipation ring block 21.

[0031] Embodiment 2: Figure 1 , Figure 2 ,Figure 3 and Figure 4 As shown in Figure 4 and , the fixing mechanism 3 includes a circular ring plate 31. One end of the circular ring plate 31 is provided with several groups of first round holes 32 penetrating therethrough. The other ends of the heat dissipation circular ring blocks 21 are each provided with first threaded holes 33. One end of the circular ring plate 31 is provided with several groups of second round holes 34 penetrating therethrough. The other ends of several groups of convex iron cores 11 are provided with second threaded holes 35. One side of each of the several groups of first round holes 32 is provided with large screws 36. One side of each of the several groups of second round holes 34 is provided with small screws 37. One end of the circular ring plate 31 is in contact with the other ends of the heat dissipation circular ring blocks 21. One ends of the several groups of large screws 36 respectively pass through the interiors of the several groups of first round holes 32 and are respectively threadedly connected to the several groups of first threaded holes 33. One ends of the several groups of small screws 37 respectively pass through the interiors of the several groups of second round holes 34 and are respectively threadedly connected to the several groups of second threaded holes 35.

[0032] The overall effect achieved by the entire embodiment is that by placing the circular ring plate 31 at the other end of the heat dissipation circular ring block 21, and aligning the several groups of first round holes 32 with the several groups of first threaded holes 33 respectively, then inserting the several groups of large screws 36 into the interiors of the several groups of first round holes 32 one by one, and inserting the several groups of small screws 37 into the interiors of the several groups of second round holes 34 respectively, and screwing the several groups of large screws 36 and the several groups of small screws 37 one by one, so that the several groups of large screws 36 are respectively screwed into the interiors of the several groups of first threaded holes 33, and the several groups of small screws 37 are respectively screwed into the interiors of the several groups of second threaded holes 35. Thus, the circular ring plate 31 can be fixed at the other end of the heat dissipation circular ring block 21, thereby being able to block the other end of the iron core ring seat 1 inside the heat dissipation circular ring block 21 and limit the iron core ring seat 1 inside the heat dissipation circular ring block 21. On the contrary, by screwing out the several groups of large screws 36 and the several groups of small screws 37 from the interiors of the several groups of first threaded holes 33 and the several groups of second threaded holes 35, it is convenient to remove the circular ring plate 31 from the other end of the heat dissipation circular ring block 21, thereby being able to conveniently take out the iron core ring seat 1 from the inside of the heat dissipation circular ring block 21, facilitating the replacement or repair of the iron core ring seat 1.

[0033] Usage method and working principle of this device: First, wind several groups of stator windings 12 around the outer walls of several groups of convex iron cores 11, then put the circular cushion plate 22 on the outer walls of several groups of convex iron cores 11. After that, place the iron core circular seat 1 into the inside of the heat dissipation circular block 21, and one end of the iron core circular seat 1 is tightly connected to one end of the circular cushion plate 22. Then, put the circular plate 31 at the other end of the heat dissipation circular block 21, and make several groups of first round holes 32 align with several groups of first threaded holes 33 respectively. Then, insert several groups of large screws 36 into the inside of several groups of first round holes 32 one by one, and insert several groups of small screws 37 into the inside of several groups of second round holes 34 respectively. And screw several groups of large screws 36 and several groups of small screws 37 one by one, so that several groups of large screws 36 are respectively screwed into the inside of several groups of first threaded holes 33, and several groups of small screws 37 are respectively screwed into the inside of several groups of second threaded holes 35, then the circular plate 31 can be fixed at the other end of the heat dissipation circular block 21. Finally, install this stator on the motor. The heat generated during the operation of the motor can flow from the gaps reserved between every two adjacent stator windings 12, which is convenient for the heat to be transferred to the outside of the stator. After that, it is absorbed by the heat dissipation circular block 21 to accelerate the discharge of the heat.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
