Advanced NdFeB Magnets for Elevator Traction Machines
Powering the Next Generation of Machine Room-Less (MRL) Elevators with High-Torque, Silent, and Energy-Efficient Permanent Magnet Solutions.
The Heart of Modern Vertical Transportation
The shift from geared induction motors to Permanent Magnet Synchronous Motors (PMSM) has revolutionized the elevator industry. Our high-grade Neodymium magnets enable compact, gearless traction machines that fit directly inside the shaft.
Extreme Thermal Stability
Elevator motors generate significant heat during peak hours. We supply UH, EH, and AH series magnets (up to 230°C) with high intrinsic coercivity (Hcj) to prevent demagnetization risks.
Low Weight Loss & Corrosion
Ensuring a long lifespan. Our magnets undergo strict HAST (Highly Accelerated Stress Test) and are coated with Phosphating or Epoxy to resist humidity in the elevator shaft.
Reduction of Eddy Currents
We offer Laminated Magnet technology (segmenting blocks with insulation glue) to minimize eddy current heating in high-speed, high-frequency elevator motors.
