Permanent Radial Ring Anisotropic Magnet, Black Epoxy Coated Sintered Neodymium Radial Magnet, Super Strong Multipole Radial Magnets, Radially Oriented NdFeB Ring Magnets, Sintered Radial Neodymium Iron Boron, Anisotropic Nd-Fe-B Ring Magnet
Black Epoxy Coated Sintered Neodymium Permanent Radial Ring Anisotropic Magnet Feature:
Due to the constraint of material, sintered neodymium used in motors is assembled into ring by segment magnet. China Magnets Supplier MPCO INC. can offer radially orientated Sintered NdFeB rings with a wide variety of grades and different coating options after researching continually in Sintered NdFeB material and its structure, orientation compression, magnetizing method, sintering and heat treatment process. Radially orientated sintered NdFeB ring greatly improve motor output properties, significantly reduce the motor loss at the same time.
The radially oriented ring magnet means that the magnetization direction of the ring magnet is in a radial pattern through radial direction. Even if many sales in the magnet industry unable to distinguish radially oriented ring magnet and diametrically magnetized ring magnet until now.
For sintered rare earth magnet, the traditional method to make multi-polar magnet is often by placing arc segments magnets on a ring shape. The intricate process and uneven distribution of magnetic field strength are always restrict the development of this method. Radially Oriented NdFeB Ring Magnets
The biggest role of radially oriented technology is helping anisotropic magnet to achieve multi-polar magnetization, and extend its application in various areas.
Known as Rare Earth magnets, Neodymium Iron Boron magnets are alloys of the Lanthanide group of elements. NdFeB magnets offer the highest energy product per unit mass, and highest energy product per unit cost of any current permanent magnet material. Energy Products range from 30 to 55 MGOe, with recommended operating temperatures from 60º – 220ºC, and the temperature coefficient of residual induction ranges from -0.09 to -0.13%/°C.

NdFeB – Sintered
MPCO Magnetics prepares its anisotropic powders by either casting an alloy melt into a mold, or strip casting. Strip casting offers the advantage of better chemical stability. Subsequently, the ingot from the mold or the flakes from strip casting are pulverized to a uniform grain/particle size. The best method for obtaining the desired grain size is by HDDR. The HDDR [hydrogenation-decomposition-desorption-recombination] process yields a more homogenous particle size with a minimum of α-Fe, and Nd-rich phases. Anisotropic Nd-Fe-B, HDDR powders prepared from strip cast alloys are used for the HAST [Highly Accelerated Stress Test] grades of NdFeB Magnets, including N, H, SH, UH, EH, and MPCO Magnetics exclusive “W” grades for Wind Power applications.
