Abstract

Higher efficiency motor becomes an expecting keyword in the sustainable society. The iron core in these motors is fabricated by piercing the amorphous electrical steel sheet with sufficient dimensional accuracy and without defects. However, this material has 2.2 GPa in the tensile strength, no ductility, and over 900 HV in hardness. Furthermore, tool life was limited to be short. In recent years, some new tooling technologies for piercing amorphous electrical steel sheets have been developed to reduce the induced damages into punched sheets.Especially, when using nano-textured tool, the process affected width was more reduced than using the nonetextured tools. In the present study, nano-texturing orientation effect on the piercing behavior is investigated and its mechanism is discussed.
