Diametrical Motor Rare Earth Magnet Arcs Of 40SH

 

 

Feature

 

1. Ndfeb arc or segment magnet has superior magnetic properties than other magnets
2. Higher unit magnetic properties  
3. Smaller size and lighter weight in designing devices
4. Mostly an iron based alloy, NdFeB type rare earth magnet is much more prone to surface oxidation or rust, and elimination. Users should consider magnet coating, plating or suitable surface treatment
5. Less prone to chipping during handling
6. Lower temperature coefficient of magnetic properties than ceramic, higher than SmCo type rare earth magnet
7. Irreversible loss at high temperature
8. High energy ranging from 8MGOe to 48MGOe with wonderful coercive force
9. Less expensive, and mechanically stronger and less brittle than SmCo

10.Density: 13%, smaller than SmCo products
