FEA Magnetic Simulation

Buyer Decision Criteria

• Input geometry quality and whether the real air gap is defined.
• Target field, uniformity zone, force, or torque requirement.
• Material grade assumptions and temperature margin.
• Which simulation outputs will become acceptance criteria.

Factory Capability

• 2D and 3D magnetic model review for product and application feasibility.
• DFM notes that connect simulated layouts to real magnet segments and fixtures.
• Comparison between simulated field targets and post-assembly mapping options.
• Early risk review for demagnetization, leakage, and assembly forces.

RFQ Preparation Checklist

1. Provide initial geometry
2. Define required field profile
3. Share magnet grade assumptions, air gap, temperature, and tolerance priorities
4. Define which simulation output becomes prototype acceptance evidence

Risk and Mitigation

• Design gap: Cross-reference with post-assembly mapping.
• Model assumes ideal magnets that cannot be assembled: Add DFM review for segment geometry, magnetization direction, fixtures, and adhesive gaps.
• Simulation output not comparable to inspection: Define probe height, measurement path, and tolerance metric during simulation review.

Validation Deliverables

• Simulation output summary with key assumptions.
• Recommended measurement or mapping method for the prototype.
• DFM issue list for tooling, assembly, and material selection.
• Quote scope notes linked to the approved magnetic target.

RFQ to Delivery Flow

1. Send CAD, target field or force, air gap, material assumptions, and tolerance priorities.
2. We return feasibility notes and missing inputs before formal sample quotation.
3. Prototype plan links simulation outputs to measurable acceptance criteria.
4. Production control uses the approved simulation and mapping baseline.
