Allstar Magnetics now offers high efficiency multipole magnetic rings. These Neodymium (NdFeB) rings are revolutionizing the permanent magnet space for synchronous motors, stepping motors and DC brushless motors widely used in automotive, computers, electronics, communications, office, school equipment and common household products. Until recently, full magnetic rings (FMR) were made of separate magnets joined together to create the desired ring shape. Now new technology enables the creation of super strong, one piece, multi-pole radial magnetic rings.

The advantages are significant:
• Motor assembly is made much easier; installation of one or more rings versus gluing arcs into place.
• Radial sintering assures no “weak spots”.
• Magnets are multi-poled – thus the ring does not compromise the magnetic properties
• The radial orientation results in a super strong magnet by virtue of superior metallurgy developed specifically to BE radially oriented.
• Geometric precision
This process consists of combining nanocrystalline base powders, pressing the resulting material, and then baking or sintering the resulting ring to achieve a radially magnetized product. This new technology improves the magnetic flux which in turn provides better efficiency and performance.
*Special sizes may be produced depending on the grade, height-to-diameter ratio, and wall thickness.
