Abstract
For quality control of Nd-Fe-B sintered magnets motor, a prototype prediction and screening tool applying less than 400kA/M magnetic field for Neodymium Magnet without Magnetization and measuring flux density distribution with hall sensor array was developed . And co-relationship between flux density distribution after applied less than 400kA/m magnetic field and flux density distribution after applied 4800kA/m magnetic field was observed.
As the result, we confirmed the possibility of prediction and screening approach for Neodymium magnet without magnetization using the above co-relationship.
