This product is hollow cylindrical neodymium magnet, which is mainly used in hollow cup motor or industry. Sintered neodymium iron boron permanent magnet is generally used in hollow cup motor. It has the characteristics of high remanence, high coercivity and high magnetic energy product. It is the permanent magnet material that most meets the requirements of hollow cup motor in the market. Under the same size of motor and winding data, the performance of magnetic steel directly affects the speed of motor. The common Nd-Fe-B magnetic steel suitable for hollow cup motor is circular, with properties such as N40 and N45, and the temperature resistance is about 100 ℃.
Various specifications can be customized according to your requirements. Please provide information such as outer diameter, inner diameter, height, neodymium magnet grade and so on.
