摘　　要：介绍了日本开发的冲片性能、机械性能和磁性能优良的高速高效电机用电工钢板。为了获得这种电工钢板,需要添加Cr、Sb和Sn。将杂质元素C、N的总量控制在0.01%以下,且两者分别降低到0.005%以下时,可使所制造的电机效率达80%以上。A type of electrical steel sheet with excellent blanking workability, mechanical property and magnetic properties suitable for high speed and high efficiency motor in Japan was developed. In order to obtain this material, adding of Cr, Sb and Sn are nece- ssary. The total content of C and N is less than 0.01%,the C and N content is less than 0.005%,recpectively,the motor efficiency can be larger than 80% .
