Eddy Current Brakes

Buyer Decision Criteria

• Kinetic energy, entry speed, braking distance, and conductor geometry.
• Temperature rise in the conductor and demagnetization margin in magnets.
• Mounting, gap, environmental exposure, and fail-safe behavior.
• Validation method for braking force versus speed.

Factory Support Scope

• Linear, curved, or ring Halbach assemblies for brake modules.
• High-temperature magnet grade and coating selection.
• CNC carriers for stable gap and installation alignment.
• Field mapping for customer braking-force simulation.

RFQ Preparation Checklist

1. Kinetic energy to dissipate
2. Braking distance constraints
3. Entry speed, conductor material, duty cycle, and allowed temperature rise
4. Mounting gap, fail-safe behavior, and braking force test method

Risk and Mitigation

• Thermal demagnetization: High-temperature NdFeB or SmCo magnets.
• Overstated low-speed stopping force: Evaluate braking force across the full speed curve and include mechanical stopping strategy if needed.
• Conductor overheating during repeated stops: Define duty cycle, cooling path, conductor material, and temperature limit before magnetic layout freeze.

Validation Deliverables

• Field profile at the specified working gap.
• Critical dimension and mounting datum inspection.
• Grade, coating, and temperature-rating documentation.
• Packaging notes for strong magnetic modules.

RFQ to Delivery Flow

1. Send speed, mass, target deceleration, gap, conductor material, temperature, and quantity.
2. We review field layout and thermal-grade needs before quote freeze.
3. Prototype arrays support customer braking-force testing.
4. Production follows the approved field, carrier, and packaging controls.
