    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 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.

    MPCO Magnetics offers high efficiency multipole magnetic rings. Multipolar sintered neodymium ring magnet is one of our most recent product developments, for which we developed specific raw material and production methods. This ring magnet is meant to replace the commonly used segment magnets, e.g. for application in the drive technology sector.

    The advantages are significant:
    The cylindrical shape allows smaller mechanical tolerance compared to segment magnets
    Motor assembly is made much easier; installation of one or more rings versus gluing arcs into place.
    Currently attainable qualities: 35H, 40H, 45H, 38M, 35SH, 38SH, 42SH, 35UH, 40UH
    Radial sintering may prevent so-called “weak spots”
    Homogeneous flux of the poles
    Uniformity of the magnetic field is significantly better than that of segment magnets
    Magnets are multi-poled – thus the ring does not compromise the magnetic properties
    Ring magnets offer substantial cost savings on assembling the rotor
    No additional rings or protecting cases are required for fixation
    Different types of magnetization are possible: diametrical, multipolar as well asso called “skewed” magnetization
    This ring provides high cost-effectiveness as well as better motor performance (as compared to the usual segment magnets)
    The radial orientation results in a super strong magnet by virtue of superior metallurgy developed specifically to BE radially oriented.

    Nickel or Epoxy Plated NdFeB Skewed Multipolar Ring Magnets Introduction:
    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.
