Title:
磁気駆動装置
Document Type and Number:
Japanese Patent JP2008535462
Kind Code:
A
Abstract:
A primary disc and the secondary discs are each fitted with magnetic means, typically in the form of permanent magnets of the same polarity, located along a radial line from the centre point of the discs, and arranged generally transverse to the axis of rotation of the respective disc. These magnets are also located at or adjacent to the periphery of the disc(s). The magnets are embedded into each of the primary and secondary discs such that the faces of the magnets are flush with the exterior faces of the primary and secondary discs. In some embodiments, the magnets on the primary and secondary discs are arranged so as to be parallel, with their respective elongate, straight side edges aligned. Such an arrangement can result in less slippage between the discs which hold the magnets, and can assist in handling some misalignment which may occur between these discs during use, thus allowing smoother operation.
