Epoxy Coating Bonded Neodymium Magnet Multi Pole Neodymium Boron Magnets
Multi Pole Magnet Ring For Stepping Motor
Product Description:
Bonded Neodymium Magnet is a kind of injection bonded magnet made from NdFeB alloy powder. It is featured by high magnetic performance, stable magnetic properties, and strong corrosion resistance. The multi pole ring shape provides maximum magnetic holding force in an axial direction. It is available in a range of sizes and shapes, and customized services are also available. Besides, it offers a variety of coating options, including epoxy, nickel, parylene, etc. for various applications. The packaging is usually carton box, pallet, etc. Bonded Neodymium Magnet can be widely used in spinder motor, stepping motor, synchronous motor, DC motor, brushless motor, etc.
