China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Because ferrite multi-pole magnetic ring in some applications can not meet the use requirements, so many users began to turn to higher magnetic properties of neodymium iron boron multi-pole ring magnets, today's topic is also to introduce this multi-pole orientation neodymium magnets.
The classification of NdFeB multi-pole magnetic ring is introduced;
NdFeB multi-pole magnetic rings can be divided into: bonded neodymium multi-pole magnetic rings, injection molded NdFeB multipole magnetic rings, powder metallurgy sintered NdFeB multi-pole magnetic rings according to the production method.
Introduction to the advantages and disadvantages of NdFeB multi-pole magnetic rings;
Neodymium multi-pole magnetic ring magnetic poles display 10 poles;
1. Advantages and disadvantages of bonded NdFeB multi-pole magnetic rings;
Advantages: easy to mold, high precision, low loss, can be processed into ultra-thin wall thickness.
Disadvantages: low operating temperature, poor processing performance.
2. Advantages and disadvantages of injection molded NdFeB multi-pole magnetic rings;
Advantages: not easy to occur gap, fracture
Disadvantages: due to the low magnetic powder loading in injection molded magnets, their magnetic properties are lower than bonded, sintered molded magnets.
3. Advantages and disadvantages of powder metallurgy sintered NdFeB multi-pole magnetic rings;
Advantages: extremely high magnetic properties
Disadvantages: need to use more medium and heavy rare earths, easy to crack and deformation, high radiation orientation magnetic field design difficulties.
The above is about the classification and advantages and disadvantages of NdFeB multi-pole magnetic ring introduction, have multi-pole ring magnets inquire samples or quote price demand welcome to contact Courage motor magnet manufacturers.
