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.
