Grade 35M–50M Sintered Neodymium Magnet for Servo Motors – IATF 16949 Certified
Meta Title: 35M–50M Neodymium Magnet Servo Motors | IATF 16949 Certified
Meta Description: High-energy 35M–50M sintered NdFeB magnets for servo motors. IATF 16949 certified, ±0.05 mm precision, epoxy or Ni-Cu-Ni coating, custom shapes. Same-day quote.
  1. Product Overview
    Deliver higher torque density and lower cogging in compact servo motors with our Grade 35M–50M sintered neodymium magnets. Manufactured in an IATF 16949-certified facility, each magnet meets automotive-grade PPAP, dimensional, and magnetic consistency requirements. Perfect for servo motors, linear actuators, robotic joints, and CNC spindles.
  1. Key Benefits
• Grade Range 35M–50M – Br 11.7–14.3 kG, (BH)max 35–50 MGOe for maximum torque per volume.
• IATF 16949 Certified – full PPAP support, CPK ≥1.67 on critical dimensions.
• ±0.05 mm Tolerance – press-fit into rotors without secondary machining.
• Thermal Stability 100 °C – optimized for 80 °C continuous servo windings.
• Multi-layer Coating Options – Ni-Cu-Ni, Zn, epoxy, parylene for 500 h salt-spray resistance.
• Custom Arcs & Rings – laser-cut edges, 2–64 pole magnetization.
