摘　　要：基于电磁场理论和麦克斯韦方程组,推导了含有实体电枢和绕制电枢涡流的磁场控制方程,并对此进行有限元求解;利用电磁场仿真软件ANSOFT Maxwell对实体电枢和绕制电枢的轴向电磁力、速度和电流分布进行了仿真,并对此进行对比分析,得出绕制电枢的电磁特性优于实体电枢,为下一步绕制电枢的制造和加工打下基础。Based on Maxwell equation and electromagnetic field theory,magnetic field control equations with eddy current of solid armature and wound armature are presented in this paper.The equations are solved by finite element method.Based on finite element software ANSOFT Maxwell,the simulative research on axial electromagnetic force,speed and eddy current distribution of solid armature and wound armature are made in ANSOFT.Through comparison of them,it is concluded that the electromagnetic characteristics of wound armature are better than solid armature,which forms the foundation for wound armature fabrication and handling.
