[0019] 1. The core assembly is extended along the circumference of the base. The core assembly is used as a stator and is installed on the base through a limit assembly. In the first direction, the limit assembly cooperates with the core assembly and the base respectively, so that in the first direction, the limit assembly limits the position of the core assembly on the base. The first end of the core assembly abuts against the base, and in the second direction, the limit assembly is used to abut against the second end of the core assembly, so that in the second direction, the limit assembly limits the position of the core assembly on the base.

[0021] 3. In order to further realize that the core assembly is fixed to the machine base in the second direction, the second limiter is installed on the machine base, at least part of the second limiter is located on one side of the core assembly and abuts against the core assembly; in the second direction, the second limiter is used to limit the position of the core assembly on the machine base; and the second limiter is arranged close to the first limiter, so that the limiting points of the first limiter and the second limiter are close to each other, which is convenient for installing the limiter assembly.

[0023] 5. To further fix the core assembly to the base, the protrusion cooperates with the second groove to clamp the core assembly to the base, thereby preventing the core assembly from moving in the circumferential direction of the base and further improving the stability of the core assembly on the base.

[0024] 6. By setting two sets of limit assemblies and setting them relative to the axis of the machine base, the position of the core assembly on the machine base is further limited, thereby improving the stability of the core assembly on the machine base.

[0025] 7. The outer diameter of the first base body is greater than the outer diameter of the second base body. The first base body is sleeved on the outside of the second base body to form a third groove.

[0027] 9. The stator mechanism is applied to the traction machine to improve the assembly efficiency of the traction machine while fixing the core assembly on the machine base. BRIEF DESCRIPTION OF THE DRAWINGS

In the first direction, the stop assembly 40 cooperates with the core assembly 30 and the base 10 respectively, so that in the first direction, the stop assembly 40 limits the position of the core assembly 30 on the base 10. The first end of the core assembly 30 abuts against the base 10, and the limiting assembly 40 is used to abut against the second end of the core assembly 30 in the second direction, so that the limiting assembly 40 limits the position of the core assembly 30 on the base 10 in the second direction. By limiting the position of the core assembly 30 on the base 10 in two directions, the stability of the core assembly 30 on the base 10 is improved; moreover, during installation, it is only necessary to first install the core assembly 30, and then install the limiting assembly 40, so that the limiting assembly 40 fixes the core assembly 30, and there is no need to set a plurality of bolts along the circumference of the base 10, thereby improving the assembly efficiency of the stator mechanism 100.

[0046] In order to further realize the first direction, the core assembly 30 cooperates with the base 10. Figures 3 to 5 As shown, the limiting assembly 40 has a first limiting member 42, the core assembly 30 has a first groove 322, the base 10 has a second groove 201, the first groove 322 is arranged opposite to the second groove 201, and a mounting hole is formed between the first groove 322 and the second groove 201, and the first limiting member 42 is installed in the mounting hole; in the first direction, the outer wall of the first limiting member 42 is respectively fitted with the inner wall of the first groove 322 and the second groove 201.

When the core assembly 30 is installed on the base 10, the first groove 322 is arranged opposite to the second groove 201, and then the first limiting member 42 is inserted into the mounting hole. The outer wall of the first limiting member 42 is used to abut against the inner wall of the core assembly 30 and the outer wall of the base 10, respectively. In this way, the core assembly 30 can be further fixed to the base 10 in the first direction. In this embodiment, the first limiting member 42 is a pin.

[0047] In order to further realize the second direction, the core assembly 30 is fixed to the base 10.

The stability of the second limiting component 43 on the base 10 is improved by the two fasteners 41, so that the second limiting component 43 stably limits the core component 30 to prevent the core component 30 from moving in the second direction.

[0049] like Figures 3 to 5 As shown, there are at least two groups of the limit assemblies 40, and the two groups of the limit assemblies 40 are arranged relative to each other at the axis of the base 10. By providing two groups of limit assemblies 40 and arranging them relative to each other at the axis of the base 10, the position of the core assembly 30 on the base 10 is further limited, and the stability of the core assembly 30 on the base 10 is improved.

[0050] like Figures 1 to 4 As shown, the base 10 includes a first base body 11 and a second base body 12, both of which are columnar structures, and the first base body 11 and the second base body 12 are an integrated structure; the outer diameter of the first base body 11 is greater than the outer diameter of the second base body 12, the first base body 11 is sleeved outside the second base body 12, and a third groove 34 is formed, and the core assembly 30 is located in the third groove 34; the second base body 12 has a fourth groove 35, and the opening direction of the fourth groove 35 is opposite to the opening direction of the third groove 34.

[0051] In this embodiment, the machine base 10 further has a support shaft 20 , which is mounted on the axis of the second base body 12 . The support shaft 20 is used to support the rotor core of the traction machine 100 so that the rotor core rotates around the support shaft 20 .

[0052] like Figures 1 to 4 As shown, the first direction is the circumferential direction of the base 10, and the second direction is the axial direction of the base 10. The position of the core assembly 30 in the circumferential direction of the base 10 and the axial direction of the base 10 are limited by the limiting assembly 40, so as to improve the stability of the core assembly 30 on the base 10.

[0053] like Figures 1 to 4 As shown, the core assembly 30 includes a copper wire 33, a winding part 31, and a splicing part 32. The copper wire 33 is wound on the winding part 31, the winding part 31 is installed on the splicing part 32, and the splicing part 32 cooperates with the base 10 through the limit assembly 40. By winding the copper wire 33 on the winding part 31, and the splicing part 32 cooperates with the base 10 through the limit assembly 40, after the core assembly 30 is energized, the current interacts with the magnetic field to generate positive and negative electromagnetic torques; the positive electromagnetic torque attempts to make the rotor core rotate forward; the reverse electromagnetic torque attempts to make the rotor core reverse; the superposition of these two torques is the synthetic rotation that drives the traction wheel to rotate, thereby driving the rotor core to rotate around the stator mechanism 100, and realizing that the stator mechanism 100 drives the rotor core to rotate.

[0054] In this embodiment, the core assembly 30 has a plurality of splicing parts 32, and the plurality of splicing parts 32 are installed on the machine base 10. After the limiting assembly 40 is installed on the machine base 10, the plurality of splicing parts 32 are welded to the outer wall of the machine base 10, so that the plurality of splicing parts 32 form an integral structure; therefore, the limiting assembly 40 only needs to limit the axial position of one of the splicing parts 32 on the machine base 10 to limit the position of the entire core assembly 30.

[0055] The utility model also provides a traction machine, comprising the stator mechanism 100 as described above. The stator mechanism 100 is applied to the traction machine, and the iron core assembly 30 is fixed on the machine base 10, while the assembly efficiency of the traction machine is improved.
