Abstract: The magnetic properties of amorphous materials and silicon steel were introduced and simulated separately in high-speed motors. Based on the simulation results, the efficiency of the two materials and the differences in iron loss at different speeds were compared and analyzed. And the changes in the iron loss of amorphous materials and silicon steel under different rotational speeds were studied. The results showed that amorphous materials have obvious advantages in high-speed motors, providing material selection suggestions for motors under different rotational speed conditions.

Key words: high speed motor, amorphous alloy, iron loss, PMSM
