Abstract

The variation in the torque transmitted by a cylindrical magnetic coupling when using different types of highly coercive permanent magnets (neodymium–iron–boron or samarium–cobalt) is considered. For the example of standard magnetic couplings (magnet diameter 133 mm, air gap between the half-couplings 5 and 7 mm), the torque transmitted is found to vary without change in coupling dimensions. The torque may be varied by adjusting the shape and size of the magnets and the material employed, with the same number of magnets in each half-coupling.
