1.Sintered NdFeB permanent magnet( motor magnets)is usually be applied in wind turbines and brushless generators.

2. Coatings:
For general applications, sintered NdFeB magnets( motor magnets) may need to be coated or surface treated depending on their intended uses. Coating treatment for the sintered ND-Fe-B magnets(motor magnets) not only improve their corrosion resistance, but also appearance, wear resistance as well as appropriate for applications in clean room conditions.

For example, if the magnet(motor magnets) is intended to be used in dry atmosphere and weak corrosive environment, Zn coating is recommended.
