Radially Ring Magnets

Radially Ring Magnets, Sintered NdFeB Radial Oriented Ring, Multipole, Skewed and Uni-pole Magnetized Radial Magnetic Rings, Neodymium Radial Oriented Anisotropic Ring Magnet,  Sintered & Bonded Ferrite Radially Ring Magnets

Radial Ring Magnets are manufactured with the north and south pole on the outside diameter (OD) and inside diameter (ID). These can be used as motor magnets, sensor magnets, and any applications were multiple or single poles are required on the OD or ID of the magnet.

Radial ring is whole radial oriented ring magnet, it can be magnetized as multi-pole, skewed and uni-pole magnetized. The ring mainly used as induction magnet for motors. It can improve the motors’ performance and property. It is the future development tendency of motor magnets. MPCO is one of the best sintered NdFeB ring magnet manufacturer in China.

Radially Ring Magnets

Radial Ring magnets can be manufactured as a single magnet but with limitation on size. Single radial ring magnets are limited to 60mm on the OD, 12mm on the ID, and approximately 10mm on the thickness. These single pieces can be magnetized with the same pole all around the OD, or alternating poles on the OD. Radial Rings made in a single piece usually include separate tooling charges for manufacturing and the magnetizing fixtures.

Radial Ring magnets can also be manufactured in magnet arc segments. These segmented radial rings allow for larger sizes on the OD, but the ID is limited to 12mm or larger on the ID. These radial rings made with magnet segments can be magnetized with the same pole all around the OD, or alternating poles on the OD. Radial Rings made with segments usually include tooling charges for manufacturing only and will include a non-magnetic ring on the OD or ID to assist with assembly of the magnet arc segments.

Multipole, Skewed and Uni-pole Magnetized Radial Magnetic Rings

MPCO has been assisting Corporate customers for many years with their custom radial ring magnet and magnetic assembly applications.

MPCO works with Corporate customers to optimize their design and then manufacture the specific ring magnet or magnetic assembly to meet the required spec. MPCO has their own ISO certified factories and controls the entire manufacturing process. For assistance from a technical representative at MPCO.

Neodymium Anisotropic Sintered Ring Magnet Major Uses
1.Spingle motor for HDDs, FDDs
2.Servomotor for robots, machinery
3.Electrical motors for power steering in automobiles, etc.
4.Actuators

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).
