- Product Overview
Boost servo-motor performance with 35M–50M grade neodymium-iron-boron (NdFeB) magnets—the sweet spot between energy density and thermal stability. Pressed, sintered, and 100 % inspected to ±0.05 mm tolerance, these magnets deliver low cogging torque and high dynamic response in compact, high-speed servo systems.
- Key Advantages
• Grade 35M–50M Range – Br 11.7–14.8 kG, (BH)max 33–53 MGOe.
• Servo-Motor Optimized – skew & multi-pole orientation reduce torque ripple.
• ±0.05 mm Precision – press-fit into rotor laminations, zero balance correction.
• Multi-Coat Protection – Ni-Cu-Ni, epoxy, parylene ≥ 500 h salt-spray.
• PPAP Ready – IATF 16949 plant, CPK ≥1.67, full traceability.
• 7-Day Prototypes – laser-cut tooling, global express delivery.
