N42 Arc Magnet For BLDC Motor

Technical details of NdFeB
Density: 7612 kg/m³ (0.275 lbs./in³);
Magnetic field required for saturation: ±35 kOe;
BHmax value of the available range of neodymium grades: 170-422 kJ/m³.

Applications

With their high strength and performance, neodymium magnets are used in many applications, such as motors,wind turbines,speakers,MRI scanners,magnetic separators etc.

Advantages
Exceptionally powerful performance;
Supplies more energy per cubic metre than any other magnetic material;
Relatively inexpensive, one-twentieth the weight of ferrite magnets and, based on ‘euro per BHmax’, approximately three-quarters the price of ferrite magnets;
Relatively easy to process, especially compared to samarium-cobalt and alnico magnets.

Production methods
Sintering is the most common and widely used process: a combination of heat and pressure produces a solid mass of magnetic material.

Surface treatment for NdFeB
Due to the poor corrosion resistance of neodymium magnets, it is advisable to provide them with a coating. A number of things are important to consider in this regard:
The commonly coated of NdFeB magnets are ZN,NICUNI,Black epoxy,etc.

Precautions when working with neodymium

Neodymium magnets can be extremely powerful. You must stay alert when using these magnets to prevent injury.

Magnetization direction:

Arc NdFeB magnet can be magnetized in three main ways(diametrical magnetized,width,thickness),it all depends on your application requirements.
