Abstract :
This paper deals with the dynamic characteristic analysis and experiments of moving-magnet linear actuator with cylindrical Halbach array. On the basis of two-dimensional analytical solutions and experiments, control parameters are obtained. Then, a dynamic simulation algorithm is established from a 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.
