ABOUT BONDED NEODYMIUM / CUSTOM MOLDED MAGNETS
Bonded magnets, also called compression bonded magnets, are an excellent choice over other magnet types. They are suitable for the application which request high magnetic field strength, general mechanical strength, and simple compression shape. Bonded magnets are manufactured by molding compression of the compound alloy powder (Neodymium or SmCo) with resin. The resin is further processed to form magnets and resistant to normal industrial solvent and automotive fluids. Since no magnetic field is applied during the compression, the finished product can be magnetized in any direction. The normal application temperatures range from below -40°C to above 165°C. Bonded NdFeB Permanent Magnet
Magnet Applications has announced a major upgrade to its neodymium compression-bonded magnet product offerings. The new BNP-12 magnet has a typical maximum energy product (BHmax) of approximately 12 MGOe, compared to the previous generation’s 10 MGOe.
The BHmax of a bonded magnet is determined by the density and the volume fraction of the magnetic material phase present in the magnet body. Magnet Applications engineers were able to improve performance by optimizing the particle size, particle distribution, chemistry, process and pressing conditions. compression molded neo magnet
The new BNP-12 magnet has a maximum operating temperature of 150° C, and is available in nearly any geometry and size.
“This significantly improved design has a 10% improvement in flux density [over] our previous generation of 10 MGOe,” said Applications Engineer Bob Fredette, who developed the new BNP-12. “This higher performance will support the increasingly demanding designs for PM motors, encoders and magnetic sensors in several industrial applications.”
Bonded magnets can offer higher magnetic strength than injection magnets due to their higher magnetic particle density, but are limited to simpler geometries.
