10.Note:OurNdFeB arc magnet is customized, glad to give some suggestions if you need.
N38SH magnets with NICUNI coating, 72hours for salt spray test as standard, to be applied to motor ,8pcs magnets with 45degree can make up of a circle. The working temperature can reach 150degree for N38SH.
Different motor request different dimensions and angles, some pieces of segments can make up of a circle around rotor.
Our magnets have good consistency , can make motor work steady.
