Hot-Pressed Magnets

Hot-Pressed Magnets

Galaxy Magnets have two types of hot-pressed Nd-Fe-B magnets, the hot-pressed isotropic Nd-Fe-B magnet (GHMⅡ) & the hot-extruded anisotropic Nd-Fe-B magnet (GHMⅢ).

The hot-pressed isotropic Nd-Fe-B magnet (GHMⅡ) is produced by hot compression with rapidly-quenched Nd-Fe-B magnetic powder under high temperature.

The hot-extruded anisotropic Nd-Fe-B magnet (GHMⅢ) is produced by the technology of hot compression-extrusion-deformation with rapidly-quenched Nd-Fe-B magnetic powder under high temperature.


Characteristics:

1、High magnetic performance, with (BH)max in magnet radial direction reaching 240～390kJ/m3.

2、The magnet ring is radially-oriented with uniform magnetic field, which can guarantee silent motor operation and smooth torque output.

3、The magnet has high temperature resistance, with working temperature reaching 200℃.

4、The magnetic pole number and skew angle of the magnet shall not be necessarily pre-designated at pressing process, but changed by adjustment of magnetization yoke, which can guarantee greater design freeness for customers.

5、The magnetic wave form of the magnet can be customized as square wave or other special wave forms.

6、The magnet ring can eliminate the process of splicing into a circle. It can be magnetized for multi-poles, which gives motor assembly convenience.

7、The magnet is Nano-crystalline structure with high density and ED coating with excellent corrosion resistance.

8、The magnet is mainly applied on many kinds of automobile motors, servo motors and brushless motors for power tools.
