Improvement of Magnetic Impact Actuator for Capsule Type Moving Device

캡슐형 구동기구를 위한 자기 충격 액추에이터의 개선

This paper is about the recent development of the magnetic impact actuator for endoscope. The developed magnetic impact actuator has many problems to arrange in the system body. Because the magnetic impact actuator need a permanent magnet as an impacter, so the magnetic interference among magnets can not be eliminated. This interference causes the system size bigger. We need a new actuator design to solve these problems. One of the good solutions is to use the closed electro-magnetic circuit. This kind of circuit enhances the actuators to be independent. It is written about the design of the electro-magnetic circuit and simulation using Maxwell(version 9.0)
