We shared the riveting points and application fields of motor stator and rotor iron core. Next, we will explain the iron core material, height, production of tightening ring and superposition fixing method.

Why should silicon steel sheet be selected as iron core material?

Silicon steel sheet is usually used as the raw material of motor iron core. Silicon steel sheet is also called silicon steel sheet. Due to high magnetic induction hardness, high stacking coefficient, smooth and flat surface and uniform thickness of silicon steel sheet, and if processed by stamping, it can obtain stamping sheet with good performance. Therefore, this material is usually selected as the raw material by motor iron core.

How to control the height of iron core products?

In order to control the height of the iron core, first set the measuring device to control the number of punching pieces on the die, then control the position of the buckle points, that is, the buckle points we process. This position should be controlled well. After that, we should also control the future. Finally, control the tightening amount and uniformity in the tightening device. These three points have been achieved, Then it is not difficult to control the height of the iron core.

Key points of making tightening ring

For the processing of the tightening ring, first select the more wear-resistant material, preferably the cemented carbide material. Secondly, it needs to be processed with high-precision equipment to obtain higher gloss and wear resistance. Then, the selection principle of the processing technology. If it can be ground, do not use slow wire processing.

What are the fixation methods of iron core superposition?

At present, there are three kinds of commonly used. The first is to break the pieces and wear them together with rivets. The second is our self buckle. Now we use the buckle instead of the rivet, and the third is to bond them with glue.
