摘要

以用于轨道交通牵引系统的电励磁磁通切换直线磁悬浮同步电动机(EEFSLMSM)为研究对象。首先分析了EEFSLMSM的结构，并对该电机的运行原理及其电磁推力与悬浮力产生的原理进行了研究。其次，建立了EEFSLMSM的数学模型，推导了该电机的电压、磁链方程以及电磁推力、悬浮力的数学表达式。然后，通过Ansys Maxwell分析了EEFSLMSM的磁场分布和空载反电动势波形，并对电机的调磁能力进行了研究。最后，通过Ansys有限元计算分析，得出了电磁推力、悬浮力和电枢电流以及励磁电流之间的关系。研究结果验证了EEFSLMSM运行的可行性，为牵引及悬浮一体化的设计提供了理论参考。

Abstract

The electrically excited flux switching linear magnetic suspension motor (EEFSLMSM) for rail transit traction systems is taken as the object of study. Firstly

the structure of EEFSLMSM is analyzed

its operating mechanism and the principle of electromagnetic thrust and levitation force generation are studied. Secondly

the mathematical model of EEFSLMSM is established

and the voltage and magnetic chain equations as well as the mathematical expressions of electromagnetic thrust and suspension force of the motor are derived. Then

the magnetic field distribution and no-load back electromotive force waveform of EEFSLMSM are analyzed by Ansys Maxwell

and the magnetic modulation ability of the motor is studied. Finally

the connection between electromagnetic thrust

levitation force and armature current as well as excitation current is obtained through Ansys finite element calculation and analysis. The results verify the feasibility of EEFSLMSM operation and provide a theoretical reference for the design of traction and suspension integration.
