| Drawing intake package | STEP or native 3D CAD, DXF when relevant, 2D PDF with tolerances, revision ID, drawing owner, and sensitive-file sharing rule. | A prototype quote is only useful when the supplier can connect geometry, CTQs, IP boundary, and review authority to the same revision. |
| Prototype objective | Geometry feasibility, material comparison, magnetic test coupon, assembly trial, full stator sample, or pilot-intent first article. | The sample route, evidence package, and cost profile change depending on whether the buyer is learning or preparing for pilot release. |
| Sample form and quantity | Coupon, tooth, segment, full annular stator, or staged batch; quantity defined by test plan, destructive testing, and spare requirement. | Low sample counts can be enough for DFM learning, but validation and repeatability usually need more than one piece. |
| Inspection and validation package | FAI dimensions, CTQ report, density or weight check, visual/coating notes, optional Hi-pot, insulation, B-H curve, or core-loss data. | Decision-ready samples should arrive with records that tell the buyer what to revise, accept, or retest. |
| Prototype-to-pilot handoff | Accepted revision, open deviation list, tooling assumption, material route, inspection scope, packaging plan, and pilot-volume forecast. | Pilot sourcing is easier when the prototype learning record already explains what must remain controlled. |
| Confidentiality boundary | Public first-contact summary, NDA-controlled CAD review, named reviewers, file handoff preference, and buyer-owned drawing statement. | AFPM stator geometry is often motor IP, so public-page inquiry needs a clear path before sensitive files move. |
