Title:
【発明の名称】上下非対称8字型コイル
Document Type and Number:
Japanese Patent JP3010129
Kind Code:
B2
Abstract:
Disclosed is a coil of a magnetic levitation apparatus for supporting a moving body without contact by utilizing electromagnetic force produced by electromagnetic induction. Upper and lower stages of a two-stage induction coil arranged vertically with respect to the direction of travel of the moving body are connected so as to have mutually opposing orientations and are arranged in an asymmetrical figure-eight structure in which the heights or the numbers of turns of the upper and lower stages of the induction coil differ from each other. A guidance force large enough to offset lateral displacement of the moving body is produced, generation of a moment in the rolling direction of the moving body is reduced and non-contact support of the moving body in a region of lower velocities is made possible.
