A Design of Realtime Monitoring System of Automatic gas Control DC-MOTOR for Single Crystal($A1_2O_3$) growth

단결정($A1_2O_3$) 성장을 위한 자동가스 조절용 DC-MOTOR의 실시간 모니터링 시스템 구현

DC-Motor is needed more and more sophisticated control to follow the highest precision of industrial automation and used in a number of control equipment or industrial fields. It is also useful to control single crystal($A1_2O_3$) growth. It is possible to procure a quality crystal utilizing a DC-Motor, if you mix Hydrogen and Oxygen gas properly and keep proper temperature in accordance with time process. In this paper, we will study about electrical valve positioning system for the gas mixture to improve the quality of single crystal($A1_2O_3$) growth and we will design about realtime monitoring systems of the automatic gas control DC- Motor for single crystal($A1_2O_3$) growth.
