Neodymium Magnets are widely used in motor applications. They can be made in variety size based on different motor design.
The grade of magnets, can be choose among material H,SH,UH or even EH series.
This magnets is N38UH High grade, under passivated coating, instead of nickel coating, passivated coating is thinner than nickel coating while makes better bonding strength between the magnets and the rotors. For this magnets, we keep the sharp chamfer in order to form a complete ring cycle. Normally, we provide round chamfer for the segments, but in this case, the magnet size is small, we suggest our client to leave the sharp chamfer which can also lead to a better motor performance. In production level, sharp chamfer is much more complicated than round chamfer. As magnets are easily break, sharp chamfer could lead to higher scrapped rate. Specially when the magnet size is small as this one.
