<p>A magnetic coupling (20) comprises first and second coupling members (21, 23), arranged concentrically within one another. Each coupling member (21, 23), has a respective series of projecting permanent magnets (3). On each of the (5) coupling members (21, 23), each of the magnets 3 has opposite faces of opposite polarity and consecutive magnets (3) are spaced from one another with the faces of consecutive magnets (3) of alternating polarity. The magnets (3) on the coupling member (21) are disposed opposite but offset from the magnets (3) on the coupling member (23). Also disclosed is a coupling member assembled by bolts or rods (10) engaging permanent magnets (Figure 8) and permanent magnet coupling members polarised perpendicularly to their axes of rotation (Figure 18c).</p> |
