Hot-Pressed NdFeB Magnet

The hot -pressed NdFeB Magnets by SPN include two types. Hot pressed isotropic NdFeB

magnet (MQ2) & Hot extruded anisotropic NdFeB magnet (Mq3).

The hot pressed isotropic NdFeB magnett is produced through compression by rapidly

quenched NdFeB magnetic powder under high temperature.

The hot-extruded anisotropic NdFeB magnet is mainly anisotropic radially -oriented ring

magnet, which is produced through compression and extrusion deformation by rapidly

quenched NdFeB magnetic power under high temperature, which characteristics as

following:

1.High magnetic performance, with the radial maximum magnetic energy product of ring

magnet reaching 240~360KJ/m3;

2. The magnet ring is radially-oriented with uniform radial magnetic performance, which

can guarantee motor`s silent operation and smooth torque output.

3. High heat-resistance, with working temperature reaching 180℃

4. The magnetizing poles and pole declination angle of the magnet ring do not have to be

reserved, which can be realized through design of changing magnetization coils, with freely

using and enough adjustment by nike air flight customers.
