Linear Halbach Arrays

High force-density magnetic arrays for linear motors and precision stages.

Target Buyer:Engineers designing high-speed, direct-drive linear motion systems.

Modular linear Halbach array with NdFeB magnets on aluminum extrusion rail

Best-Fit Procurement Use

Best fit for teams that already know the stroke, pole pitch, working gap, and target thrust profile, and need a factory-side partner to turn those constraints into repeatable magnet track modules.

Capability Highlights

One-sided magnetic flux concentration
Low ripple force by design target
Modular block designs

Typical Applications

Linear motors
Maglev tracks
Precision actuators

Engineering Focus

Field uniformity over stroke
Minimizing cogging force
Thermal stability under high load
Module-to-module pitch matching for long travel axes

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.

Key Evaluation Matrix

Metric	Typical Range	Why It Matters
Flux Density (Surface)	0.8T - 1.2T	Determines the thrust force multiplier in linear motors.
Pole Pitch Error	Project-specific, often controlled below 0.05-0.10 mm	Small pitch drift accumulates across long tracks and creates force ripple at module joints.
Working-Gap Field Map	Measured at the customer air gap, not only at surface	Lets motor teams compare supplier data with the electromagnetic model used for coil design.

RFQ Checklist

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

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

Buyer FAQ

Can you supply arrays longer than 1 meter?

Yes. Longer tracks are usually built from matched modular sections, with length and pitch tolerance set by the installation envelope and measurement plan.

Should we specify surface field or working-gap field?

Working-gap field is more useful for motor design because thrust is generated at the real air gap between coil and magnet track.

Can long linear tracks be shipped as matched sections?

Yes. For long tracks, modules can be measured, labeled, packed, and installed in sequence to reduce joint discontinuity.
