AFPM rotor magnet assembly support covering magnet sourcing, coating review, placement, bonding, balancing, and retention planning.
| Program Metric | Typical Range | Procurement Value |
|---|---|---|
| Magnet retention margin | Speed and temperature dependent | AFPM rotor safety depends on centrifugal force, thermal expansion, adhesive, and mechanical pocket design. |
| Balance evidence | Project-defined | Disk rotors require balance control to protect bearings and reduce vibration. |
| Coating and adhesive match | NdFeB coating, surface prep, and adhesive system dependent | Retention durability depends on chemical compatibility as much as magnet grade. |
| Rotor disk CTQs | Flatness, runout, concentricity, pocket position | AFPM airgap stability and noise are controlled by rotor disk geometry. |
OEM capability pages should make supplier qualification easier. Use this flow to align design responsibility, process checkpoints, outgoing records, and change control before samples move into pilot supply.
| Gate | Control Focus | Record / Output |
|---|---|---|
| Scope freeze | Rotor CAD/drawing, pole count, magnet dimensions, grade, and coating; Magnetized or unmagnetized assembly preference and magnetization fixture need | Quotation boundary, drawing revision, CTQ list, sample quantity, and test responsibility. |
| Process control | Magnetization direction, pole count, mechanical retention, and adhesive compatibility; Rotor disk material, flatness, concentricity, and balance requirement | Material route, fixture plan, in-process checks, and supplier risk log. |
| Outgoing evidence | Magnet retention margin, Balance evidence, Coating and adhesive match, Rotor disk CTQs | Inspection report, electrical screen, mechanical screen, balance or thermal notes, and lot labels. |
| Repeat supply | Confirm adhesive system, coating, surface prep, and temperature profile before build.; Use controlled fixtures, spacers, packaging, and handling notes for magnetized assemblies.; Define in-process rotor disk checks, magnet placement inspection, and final balance method before bonding. | Effective-lot change control, corrective action loop, packaging standard, and shipment milestone plan. |
Yes, subject to drawing, coating, grade, temperature, magnetization, and export requirements.
The choice depends on magnet geometry, assembly safety, fixture availability, magnetization direction, and final field verification method.
Useful records include magnet lot, grade/coating confirmation, adhesive/cure notes, placement inspection, runout or flatness checks, and balance report when required.
