Reactance Calculation and Force Analysis of Longstator Linear Synchronous Motor

本文讨论了长定子直线同步电机的主漏磁场 ,引入相应的电抗计算公式。采用基于状态方程的仿真模型 ,研究悬浮力、推力与气隙、功角之间的关系 ,为长定子同步直线电机的运行控制提供理论基础。

This paper analyses the main leakage magnetic field and presents the calculating formula of its corresponding reactance, which can be adopted by the latter simulation model. Based on the state equation model of the longstator linear synchronous motor(LLSM), the simulation studies magnetic levitation force and thrust of LLSM on different airgap and power angle. The result supplies theory base to the control system of LLSM.
