[Production Example] Stepper Motor Core

[Production Example] Stepper Motor Core

Core using press-type inner layer.

This is a laminated core for stepping motors. It was manufactured by laminating electromagnetic steel sheets with a thickness of 0.2t using round dowel rivets. Unlike the common thicknesses of 0.35t or 0.5t for laminated core steel sheets, the 0.2t round dowel rivet lamination requires a very high precision press mold. However, our company designs and manufactures the press molds for laminated core production in-house, and we have numerous achievements and know-how regarding the prototype processing of laminated cores, so we can handle the production of laminated cores with such high precision without any issues. We are capable of sourcing a variety of materials, not only general iron and SUS but also from amorphous products to special alloys, and we provide one-stop support from prototype processing of custom shims to mass production. Additionally, based on the data accumulated in our unique production management system, we offer products to customers at appropriate prices. Therefore, we also propose cost reduction from the design stage based on past processing data.
