Mainly used for lift motor/linear motor/air-conditioner compressor motor/wind power generator. The material grade are mostly from H to SH. Based on customer requirement, we can make the machining tolerance within +/-0.05mm. The coating type is generally Zn/NiCuNi/Phosphate/Epoxy and NiCuNi+Epoxy. The high magnetic energy product and high coercivity (especially high intrinsic coercivity) of neodymium iron boron make rare earth permanent magnet motors have a series of advantages such as small volume, light weight, high efficiency, and good characteristics. The improvement of energy efficiency standards promotes upgrading and upgrading, and frequency conversion technology has gradually replaced fixed frequency technology. Neodymium iron boron permanent magnet materials are mainly used in frequency conversion compressors in the field of household appliances, achieving an overall energy-saving effect of over 30%. At the same time, it has a significant effect on reducing noise and extending the service life of air conditioning.
