Abstract: 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. 

Key words: energy efficiency grade, motor, no-load loss, load loss, non-oriented electrical steel
