Problems solved by technology
[0003] Although the stator core of the above-mentioned patented structure has achieved good results, its manufacturing process is relatively complicated and has certain limitations. It is only suitable for the separated stator core. After punching out winding slots of different sizes, only one single stator core block with continuously changing width of winding slots can be processed. If it is necessary to complete the processing of the entire stator core, it is necessary to adjust the concave and convex dies one by one for many times. Position to process multiple stator iron core blocks, and finally splicing, multiple adjustments are time-consuming and labor-intensive, and dimensional errors are prone to occur, affecting splicing

Embodiment
[0034] Embodiment: A manufacturing process for a motor stator core with multiple sets of stepped winding slots, used to manufacture structures such as figure 2 The stator core shown, image 3 for figure 2 Sectional view of the internal structure along the M-M direction.
[0035] It can be seen from the above two figures that the stator core manufactured in this embodiment is composed of 15 stator core monoliths stacked together, and the number of winding slots is 6. Among the 15 stator core monoliths, there are There are three stator core monoliths with different winding slot widths. The stator core monolithic body with the narrowest winding slot width is marked as O. There are 7 pieces, located in the middle of the entire stator core, and the winding slot width is the largest. The second narrowest stator core monolith is labeled P, and there are 4 pieces, two of which are located on the outer side of the stator core monolith with the narrowest winding slot width, and the ...

The invention discloses a manufacturing process for the stator core of a multi-set stepped winding slot motor, which includes the following process steps: step A, loading; step B, punching the winding slot hole: specifically including the following sub-steps: sub-step b1, Punch a slot hole; sub-step b2, punch b slot hole; each pair of a slot hole and b slot hole are separated by a spacer; sub-step b3, punch c slot hole; after the spacer part is completely punched, several Winding slot hole; step C, punch metering holes or buckle points; step D, punch inner hole; step E, blanking; step F, cycle steps B to step E multiple times to obtain multiple pieces with different widths of winding slots Stator core monolithic body; step G, lamination: fasten multiple stator core monolithic bodies to each other to obtain the finished stator core. The invention has the advantages of high production efficiency and low production cost.
Description
technical field [0001] The invention relates to a manufacturing process of a motor stator core, in particular to a manufacturing process of a motor stator core with multiple sets of stepped winding slots. Background technique [0002] The slots of the stator core, that is, the winding slots, are used for winding the enameled wire. At present, the most common stator core is a straight slot structure, that is, the structure of each stator core is the same, so after lamination The teeth of the obtained finished stator core are completely consistent in the vertical direction. The winding slots of this stator core consume longer copper wires under the same slot fullness ratio, and the production cost is higher. Therefore, In order to save production costs, stator cores that are different from the straight-tooth structure are continuously being developed. At present, such as a laminated core disclosed in Patent Publication No. CN 101523696A, the stator cores of this structure are ...
