US 2014/0197707 A1 · MAGNETIC DRIVE APPARATUS

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.

Dependent claims

A magnetic drive apparatus comprising:

a primary and two secondary supports, each support being rotatable around an axis of rotation;
and
a plurality of magnets arranged around and at or adjacent to a periphery of each support;
wherein the secondary supports are spaced and generally parallel, and the primary support is arranged in use to move in the space between the secondary supports such that, at a given time, at least some of the primary magnets are located between at least some of the secondary magnets of each of the secondary supports.
