Custom shaft, flange, pilot, bracket, lead screw, and cable-exit interface engineering for OEM teams that need a micro planetary motor to drop into a defined housing without late-stage fit, runout, or service-access problems.
Each OEM capability needs a shared evidence path so engineering, quality, procurement, and logistics can approve the same motor configuration without relying on informal sample notes.

| Gate | Buyer Input | Factory Review | Buyer-visible Evidence |
|---|---|---|---|
| Design Freeze | Drawing revision, CAD/STEP envelope, mating part limits, load profile, voltage, speed, torque, duty cycle, and target volume. | Platform fit, interface risk, gearbox ratio route, winding direction, shaft/flange feasibility, and open validation assumptions. | Revision baseline, sample configuration direction, and risk notes before sample quotation. |
| Sample Validation | Sample quantity, acceptance limits, load fixture, torque-speed points, noise/backlash limits, temperature profile, and report format. | Dimensional check, no-load and loaded behavior, current, noise, backlash, temperature rise, and project-specific checks by scope. | Sample test summary, inspection notes, fixture assumptions, and buyer approval comments. |
| Pilot Readiness | Critical-to-quality list, EOL limits, packaging rules, label fields, incoming inspection needs, and requested quality file scope. | Assembly checkpoints, fixture notes, OQC limits, lot traceability, and PFMEA/APQP/PPAP-style evidence when requested. | Pilot inspection record, control criteria, outgoing inspection summary, and release comments. |
| Export Handoff | Destination, Incoterms, forwarder preference, certificate list, carton constraints, pallet rules, and warehouse receiving needs. | Packing protection, lot labels, document package, compliance file applicability, and shipment handoff timing. | Packing list, commercial document scope, lot reference, OQC summary, and change-control path. |
| Program Metric | Typical Range | Procurement Value |
|---|---|---|
| Shaft Runout | <0.02mm | Important for controlling vibration and runout at high speeds. |
| Interface Scope | D-cut, flat, thread, knurl, cross-hole, gear, lead screw | Clarifies what must be machined or assembled before samples are quoted. |
| Drawing Control | Buyer revision plus supplier inspection plan | Prevents fit issues when the shaft, flange, connector, and mating housing are approved separately. |
| Decision Point | Recommended Path | Validation Input |
|---|---|---|
| Simple shaft modification versus full interface redesign | Use D-cut, flat, thread, cross-hole, knurl, or length changes when the motor mounting is stable; redesign the flange or pilot when housing alignment, screw access, or cable exit drives the integration risk. | 2D shaft drawing, housing CAD, mating part geometry, load direction, assembly sequence, and incoming inspection method. |
| Material and finish selection | Use stainless steel or hardened shaft routes for corrosion, wear, or high side load; use standard steel options when cost and simple torque transfer matter more. | Torque, radial load, axial load, humidity, surface finish, hardness, coating, and expected duty cycle. |
| Inspection method and fixture control | Freeze critical datums, runout, concentricity, shaft feature dimensions, and mating fixture checks before first-article samples are approved. | Critical-to-fit dimensions, gauge method, buyer fixture, accepted tolerance stack, and sample report format. |
| Stage | Control Point | Buyer Evidence |
|---|---|---|
| Interface requirement review | Confirm shaft feature, flange pattern, pilot diameter, cable exit, connector clearance, load direction, and installation sequence. | 2D/3D drawing package, mating part CAD, assembly notes, load assumptions, and inspection priorities. |
| DFM and first-article sampling | Review machining route, material, hardness, tolerance stack, runout, concentricity, and screw or fixture access before sample build. | DFM comments, approved drawing revision, sample inspection report, and fit-test notes. |
| Pilot release and revision lock | Freeze drawing revision, inspection dimensions, fixture method, cable orientation, packaging protection, and change-control rules. | Pilot sign-off record, outgoing inspection limits, packing note, and revision-controlled PO file. |
Use this package to align drawing control, validation scope, pilot release, and export handoff before quoting custom samples or annual-volume supply.
| Package Item | Why It Matters | Buyer Input | Next Step |
|---|---|---|---|
| Drawing and STEP Baseline | Prevents shaft, flange, cable exit, connector, and mating-part assumptions from drifting during sample loops. | 2D drawing, CAD/STEP envelope, drawing revision, installation clearance, and interface-critical dimensions. | Request CAD / STEP |
| Custom Shaft & Flange Design RFQ Inputs | Keeps quotation, sample configuration, validation work, and expected annual supply tied to the same scope. | Provide 2D drawing; Specify concentricity limits; Send mating part CAD and assembly constraints; Define torque, radial load, and axial load at the shaft | Send RFQ |
| Validation and Quality Evidence | Turns prototype performance into buyer-visible limits for pilot inspection and repeat production checks. | Sample quantity, acceptance limits, test fixture, report format, CTQ list, and requested PPAP/APQP/PFMEA-style scope. | Review Quality Gates |
| Production and Export Handoff | Connects the approved sample to lot traceability, packaging, compliance file scope, and repeat overseas delivery. | Forecast, destination, Incoterms, label requirements, packing rules, certificate list, and change-notice expectations. | Export Handoff |
Standard machining modifications may avoid NRE; MOQ and setup depend on drawing, process, and volume.
Yes. Send the shaft drawing, load direction, engagement length, and tolerance requirements so the machining route can be reviewed.
Samples are checked against the approved drawing and, when supplied, the buyer mating part or installation fixture.
Include datum scheme, total length, engagement length, flats or threads, tolerance class, finish, hardness, load direction, and inspection method.
