Linear Halbach Arrays

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). Ready to optimize your linear motion design?
