摘要
阐述了电驱动汽车所用电机的特点以及对硅钢的需求标准,并通过实验对比分析了高屈服强度无取向硅钢和传统无取向硅钢的电磁性能以及力学性能,通过有限元模型验证分析应用了高屈服强度硅钢的电机在高转速时可以达到低损耗、高机械强度等需求,为软磁材料的应用与电机结构的优化形成闭环模式提供了帮助。
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.
