                                                                      Custom Neodymium Motor Magnets

The requirement for motor magnet is very critical. Dunben Magnet Co., Ltd produce a variety of arc magnets according to your requirement. At the same time, not only  rare earth magnet, but magnet component for motor we also can make for you.

High magnetic performance
grades such as N52, N50M, N48H, N45SH, N40UH, N38EH and N30AH are available. Our complete production lines help us meet different demands of customers.

high performance

High consistency

To ensure good working performance of motor, the batch-to-batch consistency and continuous stability of permanent magnet are the two of the key indices. Rely on advanced equipments and process management,

high consistency

High Working Temperature

The max working temperature for our rare earth sintered neodymium magnet can be above 220℃.The AH series with 40 kOe super-high coercive force can replace Smco magnets in most applications.

Low Weight Lost and High Corrosion Resistance

The iron-based and rich neodymium in Ndfeb magnet is equal which leads to very poor magnet corrosion resistance. To avoid oxidation, generally, neodymium magnets need to be electroplated.

As the application field expanded, such as permanent magnet motors using on elevator and wind power, the user puts forward higher requirements on corrosion resistance of ndfeb rare earth magnets. Meanwhile, compared with coated ndfeb permanent magnets, the uncoated neodymium magnets are much better to work with mating parts at the glue adhesive power; the use safety of motor also increase accordingly. Therefore, some customers began to use hast ndfeb permanent rare earth magnet a lot in their products.


 PCT: 130, humidity 100%, vapor pressure 2.7bar, 20days, average low weight loss <2 mg/cm2.

high anti-corrosionlow weight loss

The salt spray test and humidity heat test of the high anti-corrosion coating Nickel+Copper+Epoxy is typically more than 1000 hours.

Due to very low weightlessness properties, magnets have good corrosion resistance to promote reliability and service life significantly. Hast neodymium magnet can meet stringent requirement of corrosion resistance for high-end application field like permanent magnet motor. This applies mainly to elevators, radar, wind turbines and other military aerospace, industrial motors, etc.
