Bonded Magnets
The bonded Nd-Fe-B magnet is mainly produced by molding compression of the Nd-Fe-B compound alloy powder with epoxy resin, with the following characteristics:
1、Higher magnetic property: the magnetic property of bonded magnet is between that of sintered magnet and ferrite, with good consistency and stability;
2、High precision & freeness of magnet shape: the magnet shape and dimension can be guaranteed by the tooling, like ring, segment & block, etc., without further sintering and machining;
3、Good corrosion resistance: after ED coating or special surface treatment, the magnet can be applied under normal or unfavorable environment conditions in a durable period;
4、Diverse magnetization: multi-pole, skew and radial magnetization can be available. The magnetic surface can be on the ID, OD and end surface or combined magnetization. The field distribution can be square, sinusoid, etc.
The bonded Nd-Fe-B magnet can be applied on all kinds of small and micro-motors, such as spindle motor, stepping motor, synchronous motor, DC motor and brushless DC motor, and it can also be used for sorts of sensors. It can replace some sintered Nd-Fe-B magnet and ferrite, making motor assembling easier and more reliable, reducing cost and improving efficiency.
