场路耦合有限元仿真在电机类课程教学中的应用研究

The Application of Coupled Field and Circuit Finite Element Analysis to Electric Machine Teaching

利用JMAG-Studio软件建立永磁电机的场路耦合的有限元模型,计算并分析永磁电机的空载和负载时瞬态特性,直观地展示电机的电流、反电动势、磁通密度、转矩等性能,并制作成基于电机转子旋转的动画,帮助学生深入理解电机的基本概念和知识,提高电气自动化类专业的电机类课程的教学效果。

The coupled field and circuit finite element model of the permanent magnet motor are established,useing JMAG-Studio software.The transient performances of the permanent magnet machine at no-load and load are respectively calculated and analyzed.The properties of the electric machine like current,electric potential,electromagnetic torque,magnetic flux density and so on are displayed by a directly observable means.A dynamic animation based on motor rotation is made.This method is applied to help students understand better the baisc concepts and knowledge of the electric machine in the hope that the teaching effeciency of the curricula related with electrical machines can be improved significantly.
