The Influence of Pulsed Linear Electromagnetic Actuator Magnetization History on Precision and Impact Energy Stability

摘要

The influence of pulsed magnetization history in pulsed electromagnetic actuator on system output mechanical parameters has been discussed. Hysteresis behavior of pulsed linear electromagnetic actuators considerably degrades the precision and stability of impact energy system's performance. In this paper, a method is developed to provide stability for the dosed impact energy in pulsed linear electromagnetic actuators. Theoretical conclusions and experimental results have been provided.
