sintered neodymium multipole ring magnet is a new type of ring magnet, produced by special technology. By this technology, surface magnetic flux can reach top level, about 50%-100% higher than the arc magnets and radial ring magnets. The surface flux is distributed by sine wave shape. Because of its high surface gauss, it can remarkably raise the efficiency of motors efficiency, and it also helps motor to be light-weight and save raw materials.These make it to be a good choice for high-performance motors. multi-pole radial magnetic ring for sensor
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.
Epoxy Plated Multi-pole Magnetic Ring 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.
Advantage：
● Assembling easier.
● Mechanical precision better.
● Stable magnetic property.
● Improve the motor performance.
