Sintered Ferrite Segment Magnet

Sintered Ferrite Segment Magnet

The Sintered Ferrite Segment Magnet is an arc-shaped ceramic magnet manufactured through a high-temperature sintering process, designed for use in motor rotors and circular magnetic assemblies. Made from iron oxide–based materials, it offers stable magnetic performance, strong resistance to demagnetization, and excellent corrosion resistance without requiring additional coating. Its segment (tile) structure ensures precise fitting and uniform magnetic field distribution, helping improve motor efficiency and operational stability. With reliable performance at temperatures up to 250°C, it is widely used in DC motors, automotive systems, home appliances, and industrial equipment, making it a cost-effective solution for OEM projects and large-scale production.
