Exploration of solid reliability design of stator core stacking (4)

4 related process design

4.1 iron core film

When designing the punching process, in addition to designing the operating procedures of this process, the requirements of the station equipment should also be increased. It is clear that the punching sheet should be placed in the station in the order of blanking and cutting edge when the operator punches the sheet, and Mark the order, mold number, and work number on the station equipment to avoid the first and last pieces, and the mixed pieces of different molds.

4.2 Laminated

When designing the Stator Core lamination procedure, it is necessary to clarify the surface cleaning of the iron chip to ensure that the iron chip has no oil and no rust; it must be laminated according to the blanking sequence and the cutting edge direction of the same mold, and the first and last parts and different molds are not allowed. The film is mixed. It is best to use an automatic lamination stack.

Only in this way, after welding the Stator Core Laminations, it is possible to overcome the phenomenon of chipping, broken welding, unfavorable penetration, protruding pieces, etc., and to ensure the size and accuracy requirements of the stator core.

5 Conclusion

From the above exploration, the inherent reliability design of the stator core stacking includes the reliability of the electrical design, the reliability of the stacking process design and the reliability of the process design related to the stacking process. Moreover, they are mutually influential, and the advanced design can ensure that only when they are coordinated with each other and unified, can the design advancement and feasibility be ensured; the inherent reliability of the entire product design can be guaranteed. After the inherent reliability of the product is completed, it must ultimately be manufactured by the relevant worker to complete the inherent reliability of the product.

In this way, the reliability of the product is not designed by one or a few others, but can be completed by close cooperation between relevant departments, units and related personnel. Therefore, it is necessary to improve the mental and technical qualities of the relevant personnel in order to ensure the good inherent reliability and reliability of the products.
