直线同步电机特性与仿真分析

Characteristic and analysis of simulation of linear synchronous motor

依据直线同步电机的运行特点,通过合理假设,推导了直线同步电机悬浮力与驱动力的表达式,通过对磁场和力的分析,找出了它们与功角δ之间的关系表达式,并利用ANSYS软件对磁场和力进行了仿真,在功角δ从0°到360°的变化周期内,得出驱动力和法向力的变化趋势。仿真结果与数值计算结果相吻合。

Aecording to the running characteristic oflinear synchronous motor,through reasonable hypothesis,expressions of suspend force and thrust of linear synchronous motor are deduced.The formula about magnetic field and force and thrust-anger δ is deduced through analysis.Magnetic field and forces are emalated by using ANSYS.Variational trend of thrust and levitation is educed in the periods of thrustanger δfrom 0° to 360°.The emulational result conforms to that of the numerical value calculation.
