Δ Round Neodymium Rare Earth Disc Magnet Description 


Neodymium arc magnets for permanent motor generator magnets Description

Neodymium arc magnets is a special shape of rare earth magnet, Neodymium segment magnets are also called neodymium arc magnets, it is made by wire cutting of the block magnets. This neodymium arc magnets has a wide range of applications, it is commonly used in applications such as generator magnets motor magnets for permanent motor, both for rotors and stators, Wind turbine. 
It can also be used for personal creative design or for the computer hard disk magnet. If you are interested in the neodymium arc magnets generator magnets motor magnets for permanent motor or other application, you can send inquiry to us, size is customized as client’s requirement. 

This neodymium arc magnet is made of top quality high temperature NdFeB magnetic material under ISO 9002 quality systems.

The material is N42H with working temperature of 120℃ . It is magnetized through the thickness with the north pole on the inner diameter. The 4 pieces of this arc magnets can form a circle with OD=1.5″, ID=1.25″ and height =0.75″.

The following is the magnetic characteristics and the physical characteristics.
