These manetic rings are mainly used in the coreless brushless DC motors, which have following features:

◆ Have stable and good consistence in magnetic properties.

◆ High precision: All products' dimensional and geometric tolerance are controlled within 0.05mm, some special products are within 0.02mm according to customer's requirement.

◆ Good corrosion resistance: weight lost less than 2mm/cm^2, and surface coating can reach 72H above.
