The authors have been investigating the applications of a Linear Induction Motor (LIM) to a manufacturing process of sheet glass. It was found that a sheet glass can be sunk into molten metal by supplying electromagnetic force of LIM in the contrary direction to the gravity force.<br>This paper describes the study on the glass sheet elevation control with LIM in molten metal. The points discussed are followings:<br>(1) A mathematical model of the sinking length of sheet glass in molten metal is derived on the principle of the glass sheet elevation control with a LIM.<br>(2) Experiments verified that the LIM can elevate a sheet glass in molten metal and that the locus of the glass movement has a mysterious hysteresis loop, which is due to the end effect of the LIM.<br>(3) It is shown that the calculated positions of a sheet glass in molten metal are depth in 12% errors with the measured ones.<br>(4) It is clarified that the sinking length by the friction force of molten metal flow is no more than 3% compared to the gravity force and the electromagnetic force is dominant to control the elevation of sheet glass.
