Miniature Halbach Arrays
Ultra-compact permanent magnet arrays designed for micro-robotics, optical focusing, and precision voice coil motors where weight and space are strictly constrained.
Target Buyer:Consumer electronics engineers, optics designers, and micro-robotics developers.
Capability Highlights
- Sub-millimeter segment machining
- Ultra-thin non-magnetic retaining sleeves
- High-grade N52 & N54 materials
Typical Applications
- Voice Coil Motors
- Optical Lenses / LiDAR
- Micro-actuators
Engineering Focus
- Precision wire EDM cutting for microscopic segments
- Handling micro-brittleness during assembly
- Adhesive thickness control in tight gaps
Key Evaluation Matrix
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Minimum Segment Size | 0.5mm – 1mm | Allows true Halbach rotation in form factors previously restricted to simple dipoles. |
Risk Controls
- Coating chipping during assembly: Parylene conformal coating and specialized vacuum tweezers for non-impact handling.
