<p>The magnetically driven motor has two rectangular block magnets mounted along the diametrical line in the middle of a ring magnet. The two block magnets are attached to a spindle and form the rotor of the motor. The ring magnet has alternating north and south pole regions around its circumference two north poles being positioned between two south poles. In addition, the ring is magnetised in a direction parallel to its axis so that below the north poles in the ring there are south poles and vice versa.</p> |
