Product Description

Y30BH Sintered Ferrite Arc Magnet for Car Starter Motor

JOINT-MAG presents this Y30BH sintered ferrite arc magnet, purpose-engineered for automotive starter motors. Manufactured through a strict powder pressing and high-temperature sintering process, this arc magnet delivers dependable permanent magnetism for demanding engine-starting duty cycles.

Key Selling Points

  • High Coercivity Y30BH Grade: Intrinsic coercivity Hcj 302-318 kA/m resists demagnetization under high reverse fields and heavy inrush currents during engine cranking.
  • Excellent Temperature Stability: Stable magnetic performance up to 250C, ensuring reliable starter torque in hot engine compartments.
  • Corrosion-Resistant Sintered Body: Dense ceramic ferrite structure needs no coating, resisting moisture, oil and salt-spray attack over long service life.
  • OEM Custom Dimensions: Arc angle, OD, ID and thickness tailored to your starter motor design; tooling available for volume production.
  • Automotive-Grade Quality: Produced under IATF 16949 quality system with 100% dimensional and magnetic flux inspection.
