Neodymium Anisotropic
Sintered Ring Magnet

Major Uses

Features
  • 1.The cylindrical shape enables higher precision in external dimensions.
  • 2.As a rotor, 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 magnetization, skew-type magnetization possible (Radial anisotropic magnet)
  • 6.Can obtain sine surface inductive flux distribution (multi-pole oriented magnet)
