Abstract: The characteristics of the motors used in electric drive cars and the requirements for silicon steel were described, and the electromagnetic properties and mechanical properties of high yield strength nonoriented silicon steel and traditional nonoriented silicon steel were compared and analyzed by experiment. Through the verification and analysis of the finite element model, the highyieldstrength silicon steel motor can achieve the characteristics of low loss and high mechanical strength at high speed, which can help for the application of soft magnetic materials and the optimization of motor structure to form a closed-loop mode.

Key words: high yield strength, new energy vehicles, finite element design, non-oriented silicon steel
