Abstract: In recent years, the rapid development of the global new energy vehicle market, coupled with the rapid advancement of self-adhesive coating technology, has led to an increasing demand for thin gauge electrical steel. This is especially true for the high-end electric motor market, such as high-speed motors and micro motors, where the rapid progress in self-adhesive coating technology has greatly driven the demand for very-thin/ultra-thin gauge electrical steel. Currently, many electric motor manufacturers for new energy vehicles are seeking to purchase self-adhesive coated electrical steel. Numerous electrical steel companies, research institutions, coating companies, and core manufacturers are actively developing self-adhesive coating and die-cutting techniques. From this, we can observe a trend in the development of thin gauge and very-thin/ultra-thin gauge electrical steel.This article focused on elaborating on thin gauge and very-thin/ultra-thin gauge electrical steel, their current production status, development, and demand trends. 

Key words: thin gauge and very-thin/ultra-thin gauge electrical steel, production status, development trends
