Abstract

Influence of S (Sulfur) content on the iron loss deterioration by punching operation and the machinability of non-oriented electrical steel sheets was investigated. The iron loss deterioration of the higher S steels (0.020-0.025 mass% S) by punching fine pieces is less than that of the lower one (0.005 mass% S), as a result of inhibiting plastic strain effectively near punching edge in the higher's ones. Moreover, cutting tool wear and cutting burr of the higher S steel is less than that of the lower's one. It is concluded that non-oriented electrical steels containing higher S show good performance for applying to small size motors, which can be required to be higher energy efficiency and higher productivity.
