Magnetic Application Design Service
磁应用设计服务
40 years of expertise. AIC focuses on magnetic-circuit design and magnetic-product application analysis — predicting and solving magnetic-field distribution, efficiency, and material-selection challenges in the earliest design phase.

A dedicated engineering team delivers customised magnetic solutions from concept to volume production. By simulating the magnetic field at the front end of design, we identify performance bottlenecks before tooling — cutting iteration cost and shortening time to market.
From magnetic-material selection and circuit simulation to rapid prototyping and quality control, AIC covers the full application-engineering chain for motors, sensing, transmission, and adsorption products.
Core Design Capabilities
Two integrated disciplines — material expertise and field simulation — working together on every project.
Magnetic Material Selection
磁材精选
Customer-centred selection across NdFeB, SmCo, ferrite, AlNiCo and bonded magnets — balancing magnetic performance, temperature stability, corrosion resistance and cost for each application.
Magnetic Circuit Design
磁路设计
Finite-element simulation to calculate magnetic pull force, flux density and field distribution — delivering optimised circuit topologies and pole arrangements verified before prototyping.
Design Coverage — Single & Combined Circuits
From a single magnetic path tuned to a precise threshold, to multi-path assemblies delivering ultra-high field in a fixed space.
Single Magnetic Circuit
Trigger-field design for chips, and actuation-distance design for proximity or displacement sensors — one magnetic path tuned to a precise threshold.
Combined Magnetic Circuit
High-field assemblies for demanding applications — ultra-high surface field or a fixed-field region in a constrained space, built from multiple magnetic paths working together.
Design Calculation Case Studies
Real FEA-validated designs with measured results — flux density, field uniformity and holding force solved before any tooling is cut.

Uniform-Field Cavity
50 × 50 × 50 mm working volume
A near-uniform magnetic field cavity for sensor calibration and magnetic-property testing — field uniformity controlled within 0.07 T across the entire working volume.

High-Field Compact Region
Ø30 × 50 mm region
Concentrated high-flux design for applications requiring a strong field in a small, fixed space — peak 1.8 T achieved at the region boundary.

Linear High Surface Field
Linear magnetic circuit
Linear-array design achieving surface magnetic flux density above 1.66 T — for high-sensitivity magnetic sensing and strong surface attraction applications.

End-Face Holding Assembly
Ø100 × 75 mm end magnet (3D)
3D transient simulation of an end-face magnetic assembly — 1.6 T center field delivers 641 kgf end-face holding force for heavy-duty workholding and lifting.

3D Transient Field Simulation
Rotors · couplers · multi-pole assemblies
Full 3D transient FEA of rotating magnetic assemblies — flux density contour, peak field and time-varying behaviour solved before any prototype is built, covering motors, couplers and complex multi-pole designs.
Multi-Axis 3D Transient Field Analysis
One rotor assembly, solved along three field components — Y, Z and total magnitude — to fully characterise peak flux, pole balance and leakage before any prototype is built.
BᵧY-axis flux density
±2.0 TTransverse field component — reveals the bipolar symmetry of the rotor's outer pole array and confirms field balance between adjacent poles.
B_zZ-axis flux density
−1.2 to +1.0 T · peak 0.95 TAxial field component — maps end-face leakage and confirms the active flux length along the rotor axis, critical for stack-length optimisation.
|B|Total flux density magnitude
0 – 2.4 T · peak 2.2539 TVector magnitude contour — pinpoints the absolute peak (2.2539 T) on the outer magnet ring and the near-zero core (0.0018 T), the definitive map for material saturation and back-iron design.
Same component, three orthogonal views — the definitive map for material saturation limits, back-iron sizing and pole-balancing decisions.
