Magnetic Component Assembly
磁性组件
Magnetic component assemblies combine permanent magnets with soft-iron pole pieces, housings, and hardware into ready-to-install sub-assemblies. By arranging magnetic and flux-conducting elements together, the assembly raises magnetic flux density and total flux — strengthening the magnetic field while saving magnet material compared with a standalone magnet.
AIC Engineering manages the full build — from magnet selection (NdFeB, ferrite, SmCo, AlNiCo) and FEA magnetic-circuit design to precision machining, assembly, post-assembly magnetisation, 100% flux testing, and packaging. The result is a single drop-in part that reduces your supply-chain complexity and incoming inspection load.
Typical assemblies include motor rotor sub-assemblies (multi-pole rings, radial rings, Halbach arrays), sensor modules (Hall-sensor magnet + pole piece + housing), holding-magnet assemblies (pot magnets, channel magnets), and custom OEM magnetic actuators. Each assembly is built to order against your field-strength, envelope, and mounting specification.
Key Features
Integrated Sub-Assembly
Magnets, pole pieces, housing, and hardware delivered as one drop-in part — ready to install, no sub-assembly on your line.
Multi-Material Magnets
NdFeB, ferrite, SmCo, and AlNiCo selectable per assembly — matched to field strength, temperature, and cost target.
Post-Assembly Magnetisation
Magnetise after assembly so the completed sub-assembly meets the specified field pattern and strength — no handling of charged parts during build.
100% Flux Tested
Every assembly is flux-measured and inspected before shipment; ISO 9001 and IATF 16949 certified build process.

Configurable Parameters
No fixed catalogue grades — each assembly is designed to your field-strength and envelope specification. Typical ranges below.
| Parameter | Typical Range | Notes |
|---|---|---|
| Magnet Material | NdFeB / Ferrite / SmCo / AlNiCo | Selected per field, temperature, and cost target. |
| Assembly Method | Adhesive / Press-fit / Overmoulded | Adhesive standard; press-fit or overmould for high-volume. |
| Housing Material | Steel / Aluminium / Plastic | Steel for flux concentration; Al / plastic for weight or isolation. |
| Magnetisation | Pre- or post-assembly | Post-assembly for final field pattern in the assembled part. |
| Operating Temp. | −40 to 200 °C | Material-dependent; SmCo for elevated temperature. |
| Quality | 100% flux tested | ISO 9001 & IATF 16949 certified build process. |
| MOQ | 50 pcs standard | Lower MOQ available for prototyping on request. |
| Lead Time | 2 – 6 weeks | Depends on design complexity and material availability. |
Values are typical design ranges — confirmed field strength, dimensions, and lead time are provided per quotation after magnetic-circuit review.
