Product Overview
Maximize thrust density and efficiency with our precision Linear Halbach Arrays as per your specifications.
We can make them for high-performance linear motors, actuators, and magnetic levitation systems.
Our assemblies provide a focused, augmented magnetic field on the working face.
While virtually eliminating stray fields on the back side.
Unlike standard multipole arrays, our Linear Halbach configurations generate a near-perfect sinusoidal magnetic waveform.
This offers lower cogging torque, smoother motion, and higher force-to-weight ratios.
Whether you require a lightweight, glue-bonded array for high-speed automation.
Or, a mechanically retained assembly for heavy-duty Maglev applications.
We can deliver turnkey solutions manufactured to strict geometric and magnetic tolerances.
Engineering & Manufacturing Capabilities
We can handle the difficult parts of manufacturing.
Precision Assembly:
We use custom non-magnetic fixtures and hydraulic assembly jigs.
So we can properly manage the immense repulsive forces during construction.
Ensure zero gaps and perfect alignment.
Adhesive Expertise:
We select industrial-grade structural adhesives (epoxy/acrylic).
Pick the fittest one based on your operating temperature and environmental exposure.
Complete with vacuum degassing to prevent voids.
Validation:
Every array undergoes magnetic flux mapping (scan).
Will verify field homogeneity and peak flux density before shipment.
3. Customization Options (The Core Offering)
A. Magnetic Grade & Temperature Stability
We customize the magnet material based on your operating environment:
Standard High-Flux:
– N50 – N54 grades for room-temperature applications requiring maximum force.
High-Temperature Series:
– UH (180°C) and EH (200°C) grades for linear motors prone to heat buildup.
Extreme Environments:
– Samarium Cobalt (SmCo) arrays for cryogenic or extreme heat (>300°C) stability.
B. Pole Pitch & Geometry
The geometry of the array dictates the efficiency of your motor or actuator.
We offer:
Custom Pole Pitch:
We can slice magnets to non-standard widths (e.g., 5.35mm).
Make sure they perfectly match the winding pitch of your stator.
Minimize harmonic distortion.
Variable Lengths:
From micro-actuator arrays (20mm) to modular track sections (1000mm+).
Any size that can be joined for long-travel systems.
C. Mechanical Retention & Housing
For high-speed or safety-critical applications, glue alone is not enough.
We offer:
U-Channel Enclosures:
Magnets assembled inside Stainless Steel, Aluminum.
Or Titanium channels for structural integrity.
Mechanical Strapping:
External wrapping with Kevlar, Carbon Fiber.
Or non-magnetic steel sleeves.
Prevent magnet detachment under high centrifugal or shear forces.
Protective Covers:
Thin (0.2mm – 0.5mm) Stainless Steel or PEEK cover sheets.
Protect the magnets from physical impact or metal debris.
D. Environmental Coating
Epoxy Coating:
Full encapsulation for waterproof/wash-down environments.
Parylene/TiN:
Specialized thin-film coatings for vacuum compatibility (low outgassing).
