Title:
ROTATION DRIVE DEVICE USING PERMANENT MAGNET
Document Type and Number:
Japanese Patent JP2016176581
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotation device related to a permanent magnet, which uses only a permanent magnet to provide a structural technology of maintaining long-term rotation.SOLUTION: The rotation drive device is a rotation device with a permanent magnet that has: two discs in which a plurality of permanent magnets are arranged; and a rotation transmission part in which the respective discs are interlocked with each other to rotate. In the rotation drive device, places in which the magnets of the two discs are installed become multiples of inverse numbers of the rotation ratio of each of the discs. Also, it is effective that the rotational ratio is any of 2:3, 2:4, 3:2, 3:4, 3:5, 4:2, 4:3, 4:5 and 4:7.SELECTED DRAWING: Figure 1
