Description

Technical Field

[0001] This utility model belongs to the field of motor structure, and relates to a stator and rotor, and in particular to a novel stator and rotor. Background Technology

[0002] In an electric motor, both the stator and the rotor play important roles. The stator is a fixed part of the motor, usually consisting of an iron core, windings, and a frame. It forms a magnetic field with the rotor that moves relative to each other. The rotor is the rotating part of the motor, usually consisting of a shaft, a rotor core, and rotor windings.

[0003] In existing stator and rotor assemblies, the stator core and stator winding are usually designed as a single unit. Although this is convenient for processing and manufacturing, once the stator winding is damaged, it can easily lead to the complete scrapping of the stator core, requiring the replacement of the entire stator core, which is time-consuming, labor-intensive, and costly. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a novel stator and rotor assembly consisting of a separate stator core and stator windings.

[0005] This utility model can be achieved through the following technical solution: a novel stator and rotor, including a stator core, an installation groove is provided on the stator core, a positioning block is installed in the installation groove, a positioning groove is provided on the positioning block, a winding assembly is inserted into the positioning groove, a fixing block is inserted above the winding assembly, a limit groove is provided at the opening of the installation groove on the stator core, a limit ring is installed on the limit groove, a screw hole is provided on the stator core, a through hole is provided on the limit ring, and a bolt passes through the through hole and the screw hole.

[0006] In the aforementioned novel stator and rotor, a fixing groove is provided on the limiting ring, and a limiting block is installed in the fixing groove, with the limiting block abutting against the fixing block.

[0007] In the aforementioned novel stator and rotor, the limiting block has an insertion hole, and the fixing block has a pull rod extending from it, which is inserted into the insertion hole.

[0008] In the aforementioned novel stator and rotor, a connecting groove is provided on the limiting ring, a connecting plate is provided on the limiting block, and screws pass through the limiting ring and the connecting plate.

[0009] In the aforementioned novel stator and rotor, sliding portions extend from the positioning block and the fixing block, the fixing block has protrusions, and the positioning block has grooves.

[0010] Compared with the prior art, the advantages of this utility model are as follows: the stator core and winding are processed separately and then assembled, so that if a winding is damaged, a new winding can be replaced, which is convenient for maintenance and replacement and reduces costs; the limit block and the limit ring are detachably connected by screws, which is convenient for replacing and repairing damaged windings and improves maintenance efficiency.

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figures 1 to 5 As shown, this utility model can be implemented through the following embodiments: A novel stator and rotor includes a stator core 1, an installation groove 11 is provided on the stator core 1, a positioning block 2 is installed in the installation groove 11, a positioning groove 21 is provided on the positioning block 2, a winding assembly 3 is inserted into the positioning groove 21, a fixing block 4 is inserted above the winding assembly 3, a limiting groove 12 is provided at the opening of the installation groove 11 on the stator core 1, a limiting ring 5 is installed on the limiting groove 12, a screw hole 13 is provided on the stator core 1, a through hole 51 is provided on the limiting ring 5, and a bolt 6 passes through the through hole 51 and the screw hole 13.

[0014] The winding assembly 3 is positioned and installed in the mounting groove 11 by the cooperation of the positioning block 2 and the fixing block 4, which facilitates the replacement of the winding by removing the fixing block 4. At the same time, different positioning blocks 2 and fixing blocks 4 can be replaced to replace different winding assemblies 3 to adapt to different motors. The limit is used to restrict the fixing block 4, thereby restricting the fixing block 4, winding assembly 3 and positioning block 2 in the mounting groove 11 to prevent the fixing block 4, winding assembly 3 and positioning block 2 from falling off. The bolt 6 is used to fix the limit ring 5 and the stator core 1, which facilitates disassembly and assembly.

[0015] like Figure 1 , Figure 3 and Figure 5 As shown, a fixing groove 52 is provided on the limiting ring 5, and a limiting block 7 is installed in the fixing groove 52, which abuts against the fixing block 4. The fixing groove 52 is used to remove a single fixing block 4 from the mounting groove 11, thereby replacing the damaged winding assembly 3, improving maintenance efficiency and avoiding the need to disassemble the limiting ring 5.

[0016] like Figure 3 and Figure 4 As shown, the limiting block 7 has an insertion hole 71, and the fixing block 4 has a pull rod 41 extending from it. The pull rod 41 is inserted into the insertion hole 71. The insertion hole 71 and the pull rod 41 cooperate to facilitate the positioning and installation of the limiting block 7 and the fixing block 4, and to prevent the limiting block 7 and the fixing block 4 from wearing due to friction. At the same time, the pull rod 41 makes it easy for maintenance personnel to remove the fixing block 4 from the mounting groove 11.

[0017] like Figure 1 , Figure 3 and Figure 5 As shown, the limiting ring 5 has a connecting groove 53, and the limiting block 7 has a connecting plate 72. Screws 8 pass through the limiting ring 5 and the connecting plate 72. The connecting groove 53, together with the connecting plate 72, enables the limiting block 7 to be positioned and installed on the limiting ring 5. The screws 8 make it easy for users to remove the limiting block 7 and then remove the fixing block 4 by removing the screws 8, thus improving maintenance efficiency.

[0018] like Figure 3 As shown, sliding portions 9 extend from the positioning block 2 and the fixing block 4, the fixing block 4 has a protrusion 42, and the positioning block 2 has a groove 22. The sliding portions 9 are used to cooperate with the mounting groove 11 so that the positioning block 2 and the fixing block 4 are slidably installed in the mounting groove 11, improving the efficiency of disassembly and assembly; the groove 22 and the protrusion 42 are used to connect the positioning block 2 and the fixing block 4, so that the fixing block 4 and the positioning block 2 are less likely to rub against each other due to motor vibration when the motor is working, thus improving the service life of the fixing block 4 and the positioning block 2.

[0019] The working principle of this utility model is as follows: After the assembly is completed, if the winding component 3 is damaged, turn the screw 8 to remove the limit block 7, then hold the pull rod 41 to remove the fixing block 4, and then take out the winding component 3 and replace it. Finally, reverse the above steps to complete the maintenance work.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0021] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
