The sample is a multipole (8 poles)bonded neodymium magnet. The outer diameter is 45mm, the inner diameter is 38mm, thickness is 20mm. The magnet is plated black epoxy, the surface coating color is black. The surface coating of bonded neodymium magnet is generally epoxy (also can pkated nylon, polyphenylene sulfide) , It can widely used in spindle motor, Audio-visual equipment, instrumentation, micro motor, brushless DC motor, synchronous motor, power tools, automation equipment and other fields.

The advantages of bonded neodymium magnet:

The bonded neodymium magnets have high dimensional accuracy, one-time molding, good magnetic uniformity, multi-pole orientation, strong corrosion resistance and other characteristics. Compared with sintered Ndfeb, it can be formed at one time, without secondary processing, can be made into a variety of complex shapes of magnets, which is also sintering magnets can not be compared, the application of it can greatly reduce the volume and weight of the motor.

Our company has a large number of bonded neodymium magnetic ring molds. The specifications you are looking for are likely to be the same or similar. Please consult us for more details.
