Arc Motor Sintered NdFeB N48H Magnet – Sintered Neodymium Iron Boron Magnets or “NdFeB” magnets offer the highest energy product of any material today and are available in a wide range of shapes, sizes and grades. NdFeB magnets can be found in a variety of applications including high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors and loudspeakers. Magnetic properties will differ depending upon alignment direction during compaction and upon size and shape. Download individual spec sheets from the table below, or get the full neo catalog here for specific grades and their magnetic properties, including the trade-off in Br (and energy product) for HcJ (intrinsic coercivity, resistance to demagnetization). Material: Sintered NdFeB Grade & Working Temperature: Grade Temperature N28-N48 80ºC N50-N55 60ºC 30M-52M 100ºC 28H-50H 120ºC 28SH-48SH 150ºC 28UH-42UH 180ºC 28EH-38EH 200ºC 28AH-33AH 200ºC
Magnet Shape: Disc,Cylinder,Block,Ring,Countersunk,Segment,Trapezoid and Irregular shapes and more.Customized shapes are available Magnet Coating: Ni,Zn,Au,Ag,Epoxy,Passivated,etc Features: The most powerful permanent magnet, offers a great return for cost & performance, have the highest field/surface strength(Br), high coercivity(Hc), can be easily formed into various shapes and sizes. Be reactive with moisture and oxygen,usualy supplied by plating (Nickel, Zinc, Passivatation, Epoxy coating, etc.). Applications: Sensors,motors,filter automobiles,magnetics holders,loudspeakers,wind generators, medical equipments, etc.
Usually I never comment on blogs but your article is so convincing that I never stop myself to say something about it. You’re doing a great job Man, Keep up writing.
