Design of DC-MOTOR for $Al_{2}O_3$ Growth

단결정($Al_{2}O_3$) 성장을 위한 DC-MOTOR의 설계 및 구현

It is a quite quality concerning to control temperature of single crystalline growth as it does when you get most of heat treating products. It is also important factor to control temperature when you make the Al2O3(single crystalline) used to artificial jewels, glass of watches. heat resistant transparent glasses, Thus. it is a major interest to get the proper temperature in accordance with the time process while you are making mixture of oxygen and hydrogen to have the right temperature. In this paper, we will study of electrical valve positioning system for the gas mixture to improve the quality of products.
