MPCO manufactures bonded NdFeB permanent magnets in grade BNP-2, BNP-4, BNP-6, BNP-8L, BNP-8, BNP-8SR, BNP-8H, BNP-9, BNP-10, BNP-11, BNP-11L, BNP-12, which can be coated with back or grey epoxy. Most customers usually require ring magnets made bonded NdFeB material with multi-poles through diameter or radial magnetization. We also customize bonded magnets in arc, block shapes, etc.
Neodymium ring compression bonded magnets
Traditionally, to realize multi-pole requirement, the ring magnets used on motors are assembled by segment magnets.
But it is risky while spinning, the adhesive material is out of action. And it’s hard to control the component’s tolerance in the process of assembly. Also it’s not easy to keep magnetic properties’ consistency of all arc magnets.
A better solution is to make multi-poles on a ring magnet instead of segment formed ring.
Now we can provide multi-pole & radial ring sintered ndfeb magnet to meet this requirement. But the limiting factor for production is still a big problem and makes lots of customers seek help from other magnet materials.
Bonded magnet can be magnetized into complex patterns with multiple poles that sintered magnet can’t do. This makes multi-poles ring bonded neodymium magnet an ideal material for different types of motors and sensors.
Safety Notes for the Application and Storage of Bonded Magnets, Rare Earth Neodymium Isotropic Ring Bonded Magnet, compression Neodymium Bonded Radial Ring Magnet
Do not place magnets near person wearing electrical medical equipment, such as pacemaker, because the magnet may result in malfunction of the equipment and endanger person’s life.
Keep magnets away from magnetic memory media or other magnetic field sensitive devices such as magnetic cards, tapes, floppy disks, hard disk drivers and watches. Otherwise information stored in the media or the devices may be damaged.
Big block of magnet will strongly attract each other or attract iron steel pieces,which may cause serious injure to person.
Relatively weak in strength,bonded magnets may break into pieces when collide with other materials.Be careful in assembling magnets and prevent the finy fragments from entering into eyes or cause other injuries.
Keep magnets in good condition and avoid following environment in case that magnets become rust or weaken in mechanical or magnetic strength<
With acid, alkali, organic solvent or electrolytes.
Immersed in water or in oil
Space filled with hydrogen
Space filled with corrosive gases such as Cl2, NH3, Nox, etc.
With radioactive rays
