Traditionally, multi-pole sintered Neo ring magnets were created using multiple arc magnets glued to the assembly.  While spinning, it was not uncommon for the adhesive material to loosen and the magnet would dislodge itself.  Also, the requirements for accuracy between all of the magnets in the ring shape required the exact same physical and magnetic properties - thus many magnets would fail because of the lack of homogeneity.  

A better way is to create circular magnets with uniform poles.  By creating just one single magnet specifically designed for your application, we are able to provide your company a product that is stronger, more reliable, and more efficient. The magnets are multi-pole - which does not compromise the magnetic properties.  

The ring bonded neodymium magnets widely used in s
tepper motors,actuators,magnetic bearings,steering control motors,magnetic clutch,peripheral motors,spindle motors.
