Dynamic Analysis and Experiments of Moving Magnet Linear Actuator with/without Spring

This paper deals with the dynamic analysis and experiments of moving-magnet lineal actuator with/without spring. On the basis of two dimensional(2-D) analytical solutions and experiments, control parameters are obtained. And then, dynamic simulation algorithm is established from the voltage and motion equation. Finally, for various values of frequency, dynamic simulation results for characteristics of voltage, current and displacement of moving-magnet linear actuator are presented and confirmed through the experiments. In particular, This paper makes the PWM voltage waveform using a DSP for bidirectional voltage drive
