Hot Pressed NdFeB Ring Magnets, Strong Permanent NdFeB Magnet for DC Motor / Ring Motor Magnet, Neodymium /Permanet NdFeB/Hot Pressed Magnet for BLDC Motor, Neodymium Hot Pressed Magnet / Permanent NdFeB Hot Extrusion Magnet

The hot pressed NdFeB Ring Magnets by HSMAG 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 extrusioin deformation by rapidly quenched NdFeB magnetic power under high temperature,  whith characteristics as following:

Hot Pressed NdFeB Ring Magnets

Features
A: -High magnetic performance, with the radial maximum magnetic energy product of ring magnet reaching 240~360KJ/m3.
B: -The magnet ring is radially-oriented with uniform radial magnetic performance, which can guarantee motor’s silent operation and smooth torque output.
C: -Excellent corrosion resistance.
D: -The ED coating thickness of epoxy resin can be reached 20~35μm,
E: -The hot-extruded anisotropic radially-oriented ring magnets are mainly applied on EPS motors, servo motors, motors for electric tools and kinds of DC motors.
F: -High heat-resistance,with working temperature reaching 180ºC.
G: -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 customs.
H: -The magnetization waves of magnet ring can be customized and magnetized as square wave, sine wave and other special magnetization waves.
I: -The magnet ring without assembling can be realized multi-polarization and magnet pole declination, which is convenient for motor assembling.
J: -The magnet ring is nanometer crystalline structure with high density and ED coated by epoxy resin with excellent resistance, with thickness can be reached 20~35μm.
K: -The hot-extruded ring anisotropic radially-oriented ring magnets are mainly applied on EPS motors, servo motors, motors for electric tools and kinds of DC motors.

Neodymium magnets are an alloy of neodymium, iron and boron (NdFeB). This is the most popular and widely used type of rare-earth magnet; they are also the strongest types of permanent magnets commercially available.The leading manufacturers of neodymium magnets are the Chinese manufacturers because of their dominance in the rare earth industry. Neodymium magnets are most commonly used as motor magnets in Servo motors, DC motors, AC motors, brushless DC motors, Linear Motors and Micro Motor.

Neodymium magnets are utilized in high performance motors, separation sensors, magnetic fasteners, magnetic resonance imaging, electric generators for wind turbines and loudspeakers. The neodymium magnets posses very high strength and graded according to their maximum energy product. The relative strength of the neodymium magnets in relation to its predecessor means that the use of smaller, lighter magnets is now possible in many technological applications that require the use of magnets.
