Abstract

Dy diffused magnets which could reduce Dy content of Nd-Fe-B sintered magnets are well known as one of the method achieving high performance magnet. We have developed the demagnetization analysis method using Dy diffused magnets which have graded coercive force distribution from surface to inside of magnet. In this paper, it is discussed about the most suitable Dy diffusion methods and magnets using newly developed demagnetization analysis method and also reports their effects for motor applications.
