Title:
ELECTRICAL STEEL SHEET, AND STATOR CORE OF ELECTRIC MOTOR, COMPRISING LAMINATE OF ELECTRICAL STEEL SHEETS
Document Type and Number:
WIPO Patent Application WO/2014/024746
Kind Code:
A1
Abstract:
An electrical steel sheet which is to be used under conditions such that a compressive stress is applied onto the steel sheet, wherein a surface-processing-affected layer associated with lattice distortions is provided on at least one surface in at least a region where such a compressive stress as to exert an influence on iron loss characteristics is to be applied. The surface-processing-affected layer is formed by subjecting the surface to mechanical processing such blasting or surface grinding with a grinding wheel.
