Hot Pressed NdFeB Magnets, hot-pressed isotropic NdFeB magnet (MQ2), hot-extruded anisotropic NdFeB magnet (Mq3)
The hot pressed NdFeB magnets by Ningbo HangSeng Magnets include two types, hot-pressed isotropic NdFeB magnet (MQ2) & hot-extruded anisotropic NdFeB magnet (Mq3).
The hot-pressed isotropic NdFeB magnet 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 powder under high temperature, with characteristics as the 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 customers.
5.The magnetization waves of magnet ring can be customized and magnetized as square wave, sine wave and other special magnetization waves;
6.The magnet ring without assembling can be realized multi-polarization and magnet pole declination, which is convenient for motor assembling;
7.The magnet ring is nanometer crystalline structure with high density and ED coated by epoxy resin with excellent corrosion resistance;
8.The ED coating thickness of epoxy resin can be reached 20~35μm;
The hot-extruded anisotropic radially-oriented ring magnets are mainly applied on EPS SMC, servo SMC, SMC for electric tools and kinds of DC SMC.
Magnets could be made in many shapes with below
1.Pressing Bonded Ndfeb Magnet as a shape, size repumag better than NdFeB;
2, the working temperature is high, Tw = 150 ℃
3,Thin ring magnet, the thinnest thickness of thin ring magnet 0.5mm.
4,High Thick ring magnet its , a pressing, can do 40-45mm, 40-45mm thickness.
5, Biggest arc magnet, the large diameter ring magnet can do 120-140mm,
