radial ring magnet for motor manufacturers

radial ring magnet for motor













Radial Sintered NdFeB Ring Magnet is
developed to meet different requirements of permanent magnet servo motor, using
the new shaping method by multipole polymerization radial orientation.




Compared with segments jointed ring, radial
ring magnet can improve the output characteristics and significantly reduce the
loss of motor; it has excellent temperature stability, corrosion resistance and
temporal stability, and so on, especially applying for high precision micro
& special motor drive.










Features of GME radial ring magnet:




(1) The cylindrical shape enables higher
precision in external dimensions.




(2)Can achieve uniform magnetic density
flux distribution




(3) Fastening the magnet is simple,
enabling assembly-related cost reductions




(4) Highly reliability due to enabling
rotor construction from a single magnet




(5)Optional magnetization, including free
multiple magnetizations, skew-type magnetization possible (Radial anisotropic
magnet)




(6) Can obtain sine surface inductive flux
distribution (multi-pole oriented magnet)
