High Light Zinc coated sintered NdFeB magnet ，Sintered neodymium magnet for traction motors ，High temperature NdFeB magnet 150°C
Meta Title: Zinc-Coated Sintered NdFeB Magnet | Traction Motor Magnet | High Durability
Meta Description: ISO-certified zinc-coated sintered NdFeB magnets for traction motors. Superior corrosion resistance, 150 °C thermal rating, ±0.05 mm precision. Get instant pricing and 7-day prototypes.
  1. 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.
  1. 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.
