Abstract
This paper describes a robust design for a capacitance-drive-type linear electromagnetic solenoid (LES) using a quality engineering method and an exclusive dynamic analysis simulator. Reducing the variation in the performance significant by restrains the rise time of the current in the electromagnetic coil. In addition, the current should be kept above a specified level for a certain period. For this purpose, it is important to increase the inductance of the electromagnetic coil. In other words, it is necessary to increase the winding diameter and reduce the number of turns in order to reduce the variation in the performance. The validity of this robust design has been verified by experiments with actual solenoids. Consequently, it provides a high yield ratio.
