Description

Magnet motors widely used in motors, electrical and so on, as it appeared in the emergence of a corresponding number of high-tech products, particularly in motor applications, so many products to small and micro-oriented development. Sintered NdFeB high remanence, high coercivity and high magnetic energy product, it is widely used in servo motors, flat brushless motors and stepper motors, IT products, nuclear magnetic resonance, speaker and other products. NdFeB magnet easy to rust due to oxidation, it is usually the surface to be coated, such as zinc, nickel, silver, gold, etc. can do Phosphor and Spray Epoxy Resin to slow down the oxidation rate.   Magnetic Properties of Motor Magnets Grade Remanence Coercivity Force Intrinsic Coercive Force Max.
