Multipole Radial Ring Magnets
Multipole Radial Ring Magnets, multipole magnetic rings, Multipolar sintered or bonded neodymium ring magnet, Neodymium (NdFeB) rings
HangSeng Magnetech Inc. now 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.
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 (FMR) 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.
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.
Hot pressing is a new method of producing sintered NdFeB magnets. This process consists of combining base powders, hot pressing the resulting material, and then baking or sintering the resulting ring to achieve a radially magnetized product. This new technology improves the magnetic flux which in turn provides better efficiency and performance.
