Several methods of core lamination:

The core lamination has self fastening technology, riveting, welding, viscose and other methods, among which the self fastening technology is the most widely used and mature scheme.

Formation process of automatic lamination of iron core:

Punch riveting points with a certain geometry on the appropriate part of the stator and rotor punching plate. The form of riveting points is that the upper part is a concave hole and the lower part is convex. Then insert the convex part of the upper punching plate with the same nominal size into the concave hole of the next punching plate. Through continuous punching with a high-speed automatic punch, you can get a neat iron core arranged next to one, the burrs are in the same direction and have a certain stacking thickness.

What are the riveting points of iron core?

As for the formation process of automatic lamination of iron core, let's talk about the riveting points of iron core, which are V-type, T-type, circular, and ‐ V ‐ type ˇ ∨ ˇ "Waist" type.

What are the structural characteristics of "round" riveting points?

The "round" riveting point has the characteristics of good positioning and small penetration, so as to reduce the iron loss. There is also a waist riveting point, which has similar performance with the round riveting point and can relatively increase the pull-out force.
