Description

Technical Field

[0001] The utility model belongs to the technical field of motor equipment and relates to a stator and rotor, in particular to a stator and rotor. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and thereby drives the rotor to output torque. The stator and rotor are both important components of the motor. The two components cooperate with each other through the action of the energized coil to convert electromagnetic energy into mechanical energy.

[0003] Existing stators are usually integrally cast or formed by punching and welding. This type of stator has certain process difficulties when winding the stator winding. The winding steps are cumbersome and each winding slot needs to be individually wound with a coil before welding. When the stator winding is damaged, the motor needs to be opened to repair the stator winding. The integral stator is often fixed in the motor by glue, which brings difficulties to maintenance.

[0004] For example, the stator and rotor punchings of patent number CN201820669955.X form an air gap between the stator and the rotor to solve the instability problems such as noise and vibration caused by the high tooth slot torque of the permanent magnet motor with tooth slots. The outer contour of the rotor punching is formed by alternating closure of the first eccentric arc and the straight line segment, and the first eccentric arc and the shaft hole opened in the rotor punching form an eccentric structure, making the air gap uneven.

[0005] The above patent designs the outer contour of the rotor punching sheets to make the air gap uneven, so as to achieve the purpose of weakening the tooth slot torque. However, the stator core formed by laminating and welding the stator punching sheets still requires winding coils around the winding slots individually and then welding them, which has certain process difficulties and is not convenient for motor maintenance.

Implementation

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figures 1 to 7 As shown, the utility model can be implemented through the following embodiments: a split stator and rotor, including a stator assembly 1 and a rotor 2, a magnetic steel slot 21 is opened in the rotor 2, the stator assembly 1 includes a mounting frame 11 and a stator winding block 12, a mounting slot 111 is opened on the mounting frame 11, a slide slot 112 is opened on the mounting slot 111, a slider 121 is provided on the stator winding block 12, a winding frame 3 is installed on the stator winding block 12, a locking ring 4 is installed on the mounting frame 11, and the locking ring 4 is fixedly connected to the mounting frame 11 by bolts 5.

[0026] The integral stator is split into three parts, namely, a mounting frame 11, a stator winding block 12 and a winding frame, for ease of processing and production. The winding frame 3 and the stator winding block 12 are installed to wind the coil, and then the stator winding block 12 is installed on the mounting frame 11, which reduces the process difficulty of winding the coil and facilitates the removal of damaged coils for maintenance. The locking ring 4 is used to cooperate with the mounting groove 111 to limit and position the stator winding block 12 to prevent the stator winding block 12 from being displaced and affecting the operation of the stator and rotor.

[0027] Further explanation, such as Figure 5 As shown, a winding groove 31 is provided on the winding frame 3. The winding groove 31 is provided to facilitate winding of the coil and prevent the coil from being staggered and stuck during the winding process, thereby affecting the performance of the stator and rotor.

[0028] like Figure 1 and Figure 4 As shown, a fixing groove 122 is provided on the stator winding block 12, and a winding frame 3 is installed in the fixing groove 122. The fixing groove 122 provides an installation position for the winding frame 3, which is convenient for clamping the winding frame 3 on the stator winding block 12 and limiting the displacement of the winding frame 3.

[0029] like Figure 4 and Figure 5As shown, a positioning groove 1221 is installed in the fixing groove 122, and a positioning block 32 corresponding to the shape of the positioning groove 1221 is provided on the winding frame 3. The positioning groove 1221 and the positioning block 32 match each other, which facilitates the installation of the winding frame 3 into the stator winding block 12, and the positioning block 32 fits the positioning groove 1221 to prevent the winding frame from shifting during the installation process.

[0030] like Figures 4 to 6 As shown, a mounting hole 1222 is provided in the fixing groove 122, a clamping rod 6 is installed in the mounting hole 1222, and a clamping groove 33 corresponding to the clamping rod 6 is provided on the winding frame 3. The clamping rod 6 is clamped into the clamping groove 33 to fix the winding frame in the fixing groove 122, and the installation of the winding frame 3 on the stator winding block 12 is completed. The clamping rod 6 is clamped in the clamping groove 33, which is convenient for disassembly of the winding frame 3 and convenient for repairing damaged coils.

[0031] like Figure 6 As shown, a thrust spring 61 is installed on the clamp rod 6, and a push block 62 is provided on the side of the clamp rod 6 to penetrate the stator winding block 12. The thrust spring 61 installed on the clamp rod 6 is arranged between the clamp rod 6 and the mounting hole 1222. The thrust spring 61 provides a force to push outward to ensure that the clamp rod 6 clamps the winding frame 3. The push block 62 is used for the user to push the clamp rod 6, so as to realize the installation of the winding frame 3 in the stator winding block 12.

[0032] like Figure 5 As shown, a groove 34 is provided on the winding frame 3. The design of the groove 34 can be used to quickly cut open the damaged coil when necessary, thereby improving the efficiency of replacing the coil.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, the upper and lower end surfaces of the stator winding block 12 are provided with positioning rods 123. The positioning rods 123 extend into the locking ring 4 and the mounting groove 111 to facilitate the installation of the stator winding block 12. At the same time, the positioning rods 123 cooperate with the slider 121 and the slide groove 112 to support the stator winding block 12.

[0034] The working principle of the utility model is as follows: after the motor coil is damaged, the bolt 5 on the locking ring 4 is unscrewed, and after the locking ring 4 is removed, the stator winding block 12 with the damaged coil is removed, and the push block 62 is pushed to release the locking of the clamping rod 6 on the winding frame, and the damaged coil winding is removed, and a new coil winding is wound on the winding frame, or a new winding frame with a coil already wound is installed on the stator winding block 12, and then the stator winding block 12 and the locking ring 4 are reset.

[0035] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
