Product Overview
Engineered for the harsh environment of traction motors, our zinc-coated sintered NdFeB magnets deliver maximum magnetic energy (33-52 MGOe) combined with outstanding corrosion resistance and 150°C continuous operation. A uniform 8-12 µm zinc layer passes 1,000 h salt-spray, ensuring long-term reliability in EV drivetrains, rail traction, and heavy-duty e-motors.
Key Benefits
- Zinc Coating 8-12 µm - 1,000 h salt-spray per ASTM B117; cost-effective vs. Ni-Cu-Ni.
- High Reliability - Cpk ≥1.67, PPAP Level 3 available.
- 33-52 MGOe Energy - N35SH-N52SH grades for compact torque-dense motors.
- 150°C Thermal Rating - stable flux at EV inverter switching frequencies.
- ±0.05 mm Tolerance - press-fit into rotor laminations, zero grinding.
- 7-Day Prototypes - laser-cut tooling, fast sintering cycle.
