Y30BH Sintered Ferrite Segment Magnet for BLDC Motor Rotor
JOINT-MAG supplies Y30BH sintered ferrite segment magnets for BLDC and PMDC motor rotors. The sintered ferrite process produces a dense, dimensionally stable magnet body that keeps motor cogging torque low and efficiency high.
Key Selling Points
- Cost-Effective Motor Magnet: Delivers reliable magnetic flux at a fraction of rare-earth magnet cost, ideal for high-volume BLDC motor production.
- Thermal Stability to 250C: Maintains consistent torque output across wide operating temperatures with minimal flux loss.
- High Intrinsic Coercivity: Hcj 302-318 kA/m provides strong resistance to demagnetization from motor armature reaction fields.
- Multi-Pole Radial Magnetization: Custom pole counts and magnetization patterns available to match your rotor design.
- OEM Custom Geometry: Segment arc angle, OD, ID and length machined to print; rapid tooling for new designs.
