Bonded NdFeB Magnets
Bonded NdFeB magnet is mainly made of NdFeB alloy powder mixed with epoxy resin and pressed
1.
High magnetic properties: magnetic properties between sintered NdFeB
magnet and ferrite magnet, better consistency and stability.
2.
High dimensional accuracy and large shape Freedom: the shape and size
of the product are guaranteed by the mold, and can be directly shaped
into ring, tile, block and other free shapes without sintering and post
machining.
3. Good corrosion resistance: after
electrophoretic coating or some special treatment, it can be used in
daily or harsh environment for a long time.
4. Flexible
magnetization: the magnetic pole can be filled into multipole, oblique
pole and radial direction, the magnetization surface can be inner
circle, outer circle, end face and composite magnetization, and the
waveform can be square wave and sine wave.
Bonded NdFeB
magnets are mainly used in various micro motors, such as spindle motor,
stepper motor, synchronous motor, DC motor, brushless DC motor, and also
widely used in various sensor devices. It can partly replace sintered
Nd-Fe-B magnet and ferrite magnet, so that the assembly process of the
motor is simpler, more reliable, lower cost and higher efficiency.
