Description
The bonded NdFeB magnet is produced by molding compression of the compound alloy powder mixed with
epoxy resin.
The characteristics as follows:
1.Higher magnetic property:the magnetic property of bonded magnet is between sintered magnet and
ferrite,with good magnetic property consistency and stability.
2.Freeness of product shape and high-precision dimension:the magnet shape and dimension are decid-
ed by the tooling,like ring,segment,block,etc.,without further sintering and mechanical processing.
3.Good corrosion resistance:after ED coating or through special surface treatment,the magnet can be
workable under normal or unfavorable environment conditions for a long period.
4.Diverse magnetization methods:mult-pole magnetization and skew angle magnetization are avail-
able,and the field distribution can be square,sinusoid,etc.
5.The bonded NdFeB magnet is suitable for mass production with high-efficiency.
It is mainly used for all kinds of small and micro-motors,such as spindle motor,stepping motor,synchro-
nous motor,DC motor and brushless DC motor.It can replace parts of sintered magnet and fenite,making
motor assembling easier and more reliable,reducing costs and improving efficiency.
