Turnkey Magnetic Assemblies

Integrated magnetic assembly programs combining precision metal carriers, magnet integration, balancing checks, and compliance-document workflow support through qualified partner execution.

Core bottleneck: Robotics and motor OEM teams face procurement friction from high-temperature magnet scarcity and export-control complexity.

Turnkey Magnetic Assemblies - Magnetic Domain

Claim Boundaries

Linkup provides machining and engineering workflow support; final regulatory approvals remain with the competent authority.
Certification-sensitive references are project context only and do not imply certification ownership unless explicitly documented.
Performance statements are valid only under the test/inspection method defined in the RFQ acceptance criteria.

Manufacturable Scope

Carrier and housing machining with datum strategy for magnet stack-up accuracy
Magnet integration workflow with retention and balancing-oriented process planning
Inspection and compliance-document package planning before release
Supplier identity confidentiality with process-verified capability routing
NdFeB program coverage planning across grade window, coating route, and magnetization orientation control

Representative Part Scope

BLDC rotor sleeves and magnet pocket carriers
Outer-rotor magnetic cups and retention rings
Actuator-joint magnetic carriers and locator structures
Stator-side bonding fixtures and interface housings
Segmented NdFeB insert sets with coating-route and orientation-map requirements

Proof Checkpoints

Material grade window and magnetization orientation are locked at RFQ with drawing revision control
CMM checks on magnet-seat datums, concentricity, and runout are defined before assembly release
Dynamic balancing target path (for example ISO 21940 G2.5/G6.3 by application) is agreed before pilot sign-off
Upstream capability coverage includes grade-window control, coating-route selection, magnetization flow, and bonded assembly release records

Materials & Process Focus

NdFeB grade class selection (for example SH/UH classes) aligned to thermal envelope
Retention strategy under vibration and thermal cycling conditions
Rotor runout and balance-path planning across pilot and repeat batches
Coating-route compatibility and bonded-interface process stability

Evaluation Matrix

Metric	Typical Range	Why It Matters
Balance-path readiness	Target grade and test speed defined before pilot release	Unclear balancing targets create late-stage redesign and validation delays.
Inspection deliverable completeness	CMM + balance + material/cert pack per RFQ scope	Complete inspection packs reduce procurement and QA approval cycle time.

RFQ Checklist

Specify magnet grade class, max operating temperature, and demagnetization margin targets
Provide carrier/housing datums, concentricity or runout limits, and adhesive constraints
Define balancing acceptance target (for example G2.5/G6.3) and test speed
List required shipment documents: CoC, material certs, inspection pack, and destination compliance docs

Risk Controls

Rotor performance drift from unclear magnet and temperature assumptions: Lock magnet class and operating envelope in RFQ before DFM and tooling release.
Bonding or corrosion issues from late coating-route decisions: Freeze coating route and adhesive compatibility checks before pilot lot kickoff.
Pilot acceptance achieved but production handoff lacks required documentation: Freeze the deliverable pack (reports, certs, compliance docs) as a pre-ship gate.

Buyer FAQ

Can you ship with a complete inspection and document package?

Yes. Scope can include CMM records, balancing results, material certificates, and destination-specific compliance-document routing defined in RFQ.

Can we start with housing-only machining before full assembly?

Yes. Projects can start with housing-only scope and expand to integrated assembly workflow when ready.

Magnetic Program Evidence Asset Kit

Evidence assets below are used to align engineering, QA, and sourcing before pilot and pre-ship release.

Inspection Report Preview

Field	Sample Value	Why It Exists
Drawing revision	LP-ROT-247 Rev.C	Prevents pilot and production from running mixed revisions.
Magnet class window	N42SH (approved alternates: N40UH)	Locks thermal envelope assumptions before DFM release.
Runout / concentricity CTQ	Runout <= 0.02 mm @ datum A/B	Keeps rotor behavior inside assembly acceptance boundaries.
Balance-path target	ISO 21940 target path: G2.5 @ 6000 rpm	Defines release criteria before pilot sign-off.
Measurement method	CMM + dynamic balancing record	Creates auditable evidence for buyer QA approval.

Shipment Document Pack

CMM dimensional report for CTQ features and datum references
Dynamic balancing result record with speed/condition notes
Material certificate and CoC package per RFQ scope
Pre-shipment inspection summary with lot traceability
Destination compliance-document routing checklist

Acceptance Flow

Gate 1 - RFQ lock: Grade window, drawing revision, runout CTQ, and balance target are frozen.
Gate 2 - Pilot verification: CMM and balancing outputs are reviewed against acceptance values.
Gate 3 - Pack freeze: Shipment document pack is confirmed before production release.
Gate 4 - Pre-ship release: Lot traceability and final QA summary are checked before dispatch.
