摘　　要：电机新能效等级标准的实施,对硅钢产品提出了更高的要求。本文结合中小电机、无取向电工钢的发展,分析了电机的损耗与硅钢性能的关系,并提出了新能效等级标准实施后对无取向电工钢的需求预测。With the implementation of the new energy efficiency grade standard for motors,higher requirements were put forward for silicon steel products.In this paper,combined with the development of small and medium-sized motors and non-oriented electrical steel,the relationship between the loss of motors and the properties of silicon steel was analyzed,and the demand forecast of non-oriented electrical steel after the implementation of the new energy efficiency grade standard was put forward.

关 键 词：能效等级 电机 空载损耗 负载损耗 无取向电工钢
