Abstract
PURPOSE:To make the temperature distribution in the axial direction of a roll uniform and improve the power source utilization efficiency by making outer circumferential portions of a magnetic circuit separating body inserted between magnetic flux generating mechanisms tilt in the axial directions opposite to each other. CONSTITUTION:A magnetic circuit separating body 8 with its outer circumferential portions 8a, 8c of annular plates 8a, 8b tilted in directions opposite to each other is inserted between a magnetic flux generating mechanism 2 formed with a plurality of iron cores 3 and solenoid coils 4 mounted on and arranged in the axial direction of a rotary shaft 1 and the magnetic flux generating mechanism 2 of a roll device constituted with a hollow roll supported with the rotary shaft 1 via a supporting plate 6. With this constitution, each magnetic circuit of magnetic flux generated with the magnetic flux generating mechanism 2 becomes a closed magnetic circuit. At the same time, the part of the roll 5 near the border is heated with the heat generated with an electromotive force induced. As a result, the temperature distribution in the axial direction of the roll 5 becomes uniform and at the same time, the power source utilization efficiency is improved.
