Simulation of Dynamic Characteristics of Tubular Permanent Magnet Linear Motor with Moving Coil
Abstract
The paper analyzed working principle of permanent magnet linear motor with moving coil, gave mathematical model of permanent magnet linear motor with moving coil which is used to drive electro-hydraulic proportional valve, and built simulation model of the motor with Matlab/Simulink software. The simulation result showed that regulating time of step response of the motor is less than 30 ms when displacement instruction is 5 mm, which has good dynamic response characteristics of high-frequency.
