Linear Halbach Arrays

Buyer Decision Criteria

• Pole pitch, total track length, and segment-to-segment pitch error.
• Peak working-side flux density at the real air gap, not only at the magnet surface.
• Carrier material, mounting pattern, and stiffness requirement for long tracks.
• Thermal grade selection for continuous duty linear motor operation.

Factory Capability

• Segmented magnet sorting before assembly to reduce ripple and field deviation.
• Non-magnetic aluminum or stainless carriers with CNC datum control.
• Bonding fixtures that hold repulsive blocks during cure without shifting pitch.
• Modular packaging for long rails shipped as matched sections.

RFQ Checklist

1. Target peak flux density (Tesla)
2. Pole pitch and total length
3. Max operating temperature
4. Carrier material (Aluminum/CFRP)
5. Working air gap, active stroke, duty cycle, and target thrust ripple

Risk Controls

• Adhesive failure under sheer stress: Use of high-temp epoxies and mechanical retention plates.
• Force ripple at module joints: Match, label, and map track sections so installation follows the measured sequence.
• Carrier distortion during cure: Use machined non-magnetic fixtures and staged cure controls before final inspection.

Validation Deliverables

• Surface and working-gap Gauss map by module.
• Pole pitch inspection report for matched track sections.
• Material grade and coating confirmation.
• Assembly drawing review with mounting datum notes.

RFQ to Delivery Flow

1. Share stroke length, air gap, target force, duty cycle, and annual quantity.
2. We review field feasibility and flag pitch, temperature, or carrier-risk items.
3. Prototype modules are mapped before shipment and used to freeze production controls.
4. Mass production follows the agreed pitch, grade, coating, and inspection plan.
