OEM Buyer Decision Path
Product selection usually fails when only one team reviews the motor. Use this path to connect mechanical fit, quote scope, validation evidence, and production handoff before sample approval.
| Buyer Role | Decision Check | Page Evidence | Next Step |
|---|---|---|---|
| Design Engineering | Envelope, output speed, continuous torque, stall condition, backlash/noise limit, shaft datum, and cable route. | Performance window, engineering focus, customization map, CAD/STEP request path, and material review. | Request CAD / STEP |
| Procurement | Prototype quantity, annual volume, destination, sample timing, quote scope, and approved supplier workflow. | RFQ checklist, email template, WhatsApp handoff, and quote caveat before sample pricing. | Send RFQ |
| Quality | Incoming CTQ, drawing revision, torque-speed test condition, noise/backlash method, and lot traceability expectation. | Risk controls, validation scope, buyer file package, and quality evidence review path. | Review Quality |
| OEM Program | NPI stage, frozen BOM fields, custom tooling boundary, packing rules, revision control, and production handoff. | OEM customization options, supplier workflow, export coordination, and related application routing. | OEM Workflow |
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Acoustic Emission | < 45 dBA at 30cm | Helps compare samples against buyer-defined comfort or equipment noise targets. |
| Noise Test Condition | Distance, load, speed, housing, and background noise defined | A dBA target is only comparable when the acoustic test setup is fixed. |
| Gear Material Strategy | Plastic, hybrid, or metal stages by load and noise target | Balances quiet running against torque, temperature, and life requirements. |
Ratio & Performance Window
These RFQ reference windows translate the planning ranges into an engineering shortlist. Final datasheet values are confirmed by winding, ratio, gear material, load, duty cycle, current limit, and test condition before sample approval.
| Frame / OD | Rated Voltage | Ratio Range | No-load RPM | Rated-load RPM | Continuous Output Torque | Stall Torque | Efficiency | Application Fit |
|---|---|---|---|---|---|---|---|---|
| 6mm low-noise POM/hybrid | 3-6V DC | 5:1-700:1 | Up to 2500 RPM at 6V motor reference | Set at target dBA, load, and distance | 5-480 g.cm reference window | Verify stall without damaging quiet gear stages | POM and stage count dependent | Medical handhelds, optics, wearables |
| 10/12mm low-noise N20/N30 | 3-12V DC | 5:1-1000:1 | Motor winding dependent; quote at acoustic target | Measured under buyer load and housing condition | 100 g.cm-1.5 kg.cm reference window | Confirm jam load before choosing POM or hybrid stages | Noise tuning, grease, and ratio dependent | CPAP, blinds, smart home, small pumps |
| 16/22mm low-noise hybrid | 6-24V DC or BLDC | 4:1-1500:1 | Avoid high-speed resonance; test in enclosure | Validated at target load and acoustic condition | 0.5-5.5 Nm reference window | Use current limit to protect quiet material stack | Hybrid material and grease selection dependent | Medical devices, valves, quiet automation |
Sample Acceptance Plan
Before a motor family becomes a sample order, sales engineering converts the RFQ into acceptance checks for engineering, procurement, and quality. These checks keep CAD/STEP release, prototype approval, and repeat production tied to the same specification baseline.
| Workstream | Buyer Question | Evidence to Prepare | Pass Signal |
|---|---|---|---|
| Acoustic limit | Is the dBA target tied to a repeatable measurement setup? | Target dBA, distance, background noise, load, speed, enclosure, and microphone position. | Noise data is measured under the same setup the buyer will use for acceptance. |
| Gear and grease route | Which material and lubricant choices reduce noise without losing load margin? | Torque, ratio, temperature, life target, preferred POM/hybrid/metal stage mix, and grease constraints. | The sample meets acoustic target while keeping torque, wear, and current inside limits. |
| Mounting resonance | Will the final housing amplify motor or gearbox vibration? | Mounting stiffness, screw pattern, enclosure volume, damping material, and cable strain relief plan. | Noise remains acceptable when the sample is tested in the buyer-like housing or fixture. |
| Noise drift over life | Does the quiet sample stay quiet after cycling, temperature, and grease migration? | Cycle count, duty timing, temperature range, allowed post-life dBA change, and wear inspection plan. | Post-cycle acoustic and current data stay inside the approved acceptance band. |
Selection-Ready Product Data
Public diameter pages are only the starting point. For RFQ review, sales engineering confirms rated voltage, no-load RPM, rated-load RPM, continuous output torque, stall torque, current, efficiency, and gear ratio against your mechanism before releasing drawings or sample pricing.
| Performance Field | Buyer Input | How It Shapes the Quote |
|---|---|---|
| Rated voltage and current limit | 3V, 6V, 12V, 24V, or buyer-defined driver limit | Selects the winding, thermal margin, stall-current boundary, and battery or adapter fit. |
| No-load speed and loaded output speed | Motor RPM, target output RPM, and acceptable speed tolerance | Narrows the gear ratio and keeps the prototype inside the required actuation time. |
| Continuous output torque and stall torque | Working torque, peak load, jam condition, and stall duration | Checks gear material, shaft support, carrier strength, and safety margin before sampling. |
| Gear ratio and efficiency target | Known ratio, output RPM target, or torque-speed curve from the mechanism | Builds the ratio table used to compare speed, torque, current, efficiency, and heat rise. |
| Duty cycle and life target | On/off sequence, cycles per day, lifetime cycles, ambient temperature | Defines grease, gear stack, winding temperature, brush life, and sample validation scope. |
| Noise and backlash limit | dB limit, measurement distance, arcmin or degree target, load fixture | Separates POM, hybrid, metal, and low-backlash options before the CAD exchange. |
Customization Options
The useful custom scope is normally around the shaft, gearbox stack, feedback, cable exit, connector, and buyer file package. These options should be fixed before tooling, CAD exchange, or pilot builds.
| Custom Area | Common Options | RFQ Signal |
|---|---|---|
| Output shaft and mounting | D-cut, flat, threaded, cross-drilled, keyway, custom length, flange, bearing support. | Attach shaft datum, mating part drawing, radial/axial load direction, and installation sequence. |
| Gear material and backlash | POM, MIM, machined metal, hybrid stages, grease selection, low-backlash build review. | State torque peaks, reversing frequency, noise target, temperature, and life requirement. |
| Feedback and control | Encoder, Hall signal, EMI suppression, pinout, driver match, current-limit review. | Share CPR, signal voltage, controller type, cable route, connector drawing, and EOL test needs. |
| Cable, connector, and assembly | Lead wire length, connector model, cable exit, strain relief, bracket, harness, module assembly. | Include enclosure envelope, bend radius, pull-force concern, label rules, and packing notes. |
| Compliance and buyer file | RoHS/REACH file, material note, drawing revision, sample test report, lot traceability. | Confirm destination, regulated-market expectations, incoming inspection plan, and annual volume. |
Evidence Pack Before Sampling
These files are normally reviewed by request rather than downloaded instantly. Confirm the scope early so drawings, sample data, quality records, and production notes match the same motor revision.
| Evidence Item | What to Request | Why It Matters | Route |
|---|---|---|---|
| CAD / STEP baseline | Outer diameter, length, shaft geometry, flange datum, connector clearance, and mating-part constraints. | Prevents a mechanically suitable motor from failing because of envelope, shaft, or mounting mismatch. | CAD request |
| Torque-speed-current window | Rated voltage, no-load speed, rated-load speed, continuous torque, stall torque, current limit, and duty cycle. | Separates reference catalog windows from the sample value set that purchasing and engineering can approve. | RFQ template |
| Inspection and test evidence | Dimensional CTQ, gear ratio check, no-load current, load test, noise/backlash method, and final inspection record. | Lets the buyer define what must be proven before incoming inspection, pilot build, or supplier approval. | Quality review |
| Gear material and backlash route | POM, hybrid, or metal stage choice, grease condition, reversing motion, temperature, shock load, and noise target. | Aligns durability, acoustic behavior, backlash, cost, and life expectation before the sample BOM is frozen. | Material guide |
| OEM handoff package | Drawing revision, cable/connector rules, label and packing notes, destination, compliance file needs, and annual volume. | Turns a selected sample into a production-ready supplier package with fewer revision loops. | OEM workflow |
Gear Material Review
Use the material guide to align noise, torque density, stall load, wear, grease, and backlash expectations before the sample BOM is frozen.
CAD / STEP Request
Share the mating envelope and target duty data so sales engineering can confirm whether an existing outline drawing, STEP/IGES file, or custom shaft and flange proposal is suitable for your project.
Installation envelope, mounting pattern, shaft interface, and cable exit.
Voltage, loaded speed, torque, gear ratio, duty cycle, noise, and backlash limits.
Preferred CAD format, drawing revision, prototype quantity, destination, and compliance notes.
CAD files are shared by project fit and revision status. For custom shafts, flanges, cable routing, or gearbox interfaces, attach the mating drawing so the first CAD exchange uses the correct mechanical boundary.
POM, PEEK, or hybrid gear stages can offer good wear behavior while absorbing impact noise when load and temperature stay within limits.
Send target dBA, measurement distance, load, speed, duty cycle, enclosure condition, and any pass/fail acoustic standard.
Usually yes within limits. The design may use hybrid gear stages, controlled grease, and a larger frame to keep both noise and torque acceptable.
Include target dBA, distance, voltage, speed, load, duty cycle, housing condition, temperature range, and whether the final device has damping material.
Product Qualification Review
Send the target size, voltage, torque, speed, ratio, quantity, drawing status, and validation concerns. Sales engineering can then confirm whether this product family is the right starting point or whether another frame, gear material, or OEM assembly route is safer.
