The technology for producing rare earth ring magnets with radial magnetic fields has been around for decades, however only in recent years has the cost of manufacturing them come to a point where the magnets are an affordable replacement to traditional multi segmented arcs. There are three main manufacturing methods for producing bonded and sintered radial oriented rings: Anisotropic Pressure Molding, Hot Pressing & Backward Extrusion, Radial Rotating Field Alignment. Each of these methods produces magnets with certain advantages and disadvantages over the others.Information provided by Alliance LLC. |
