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 |
|---|---|---|
| Encoder CPR | 3 - 1000 CPR | Dictates the positioning resolution capability of the system. |
| Output Channels | Dual Channel (A/B) Quadrature | Enables both speed measurement and directional sensing. |
| Input Voltage (Vcc) | 3.3V or 5.0V | Must match your MCU logic level to avoid blowing the sensor. |
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 |
|---|---|---|---|---|---|---|---|---|
| 10/12mm encoder gearmotor | 3-12V motor; 3.3V or 5V encoder | 5:1-1000:1 | Quote from motor RPM, CPR, and controller input | Confirm pulse rate at target loaded output RPM | 100 g.cm-1.5 kg.cm reference window | Jam limit must protect gears and encoder PCB | Gear stage count plus sensor load dependent | Smart locks, optics, compact automation |
| 16/22mm encoder gearmotor | 6-24V motor; 3.3V or 5V encoder | 4:1-1500:1 | Motor winding dependent; verify pulse bandwidth | Set by closed-loop speed and load curve | 0.5-5.5 Nm reference window | Confirm overload, homing, and current cutoff | Ratio, bearing load, and feedback wiring dependent | AGV modules, valves, robot joints |
| 36/42mm encoder BLDC option | 24-48V BLDC with feedback | 3:1-512:1 | Driver and feedback bandwidth reviewed together | Validated at loaded wheel or actuator speed | 9.3-35 Nm reference window | Driver, shaft, and gearbox protection required | Optimized around BLDC drive and stage count | AGV wheels, steering axes, heavy actuators |
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 |
|---|---|---|---|
| Encoder resolution | Does the CPR/PPR target give enough control resolution after gearbox reduction? | Position tolerance, controller count rate, target RPM range, PPR/CPR preference, and logic voltage. | Measured counts, direction, and low-speed resolution satisfy the control-loop requirement. |
| Homing and jam behavior | Can the system detect end stops, missed motion, or reversal without false position confidence? | Homing sequence, jam current threshold, reversal frequency, controller logic, and backlash allowance. | The sample identifies direction, jam events, and repeatable home position under load. |
| Cable and signal integrity | Will encoder signals stay clean through the final harness and connector route? | Cable length, connector family, shielding, pull-up values, MCU voltage, and nearby EMI sources. | A/B pulses remain clean at the required speed with no connector dropout or false counts. |
| Mechanical accuracy stack | Is the positioning error dominated by gearbox backlash, encoder resolution, or linkage tolerance? | Backlash limit, shaft coupling, mounting datum, load direction, and repeatability target. | Output repeatability is measured at the load condition the buyer will use for acceptance. |
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.





We typically use magnetic Hall-effect encoders for robustness against dust and oil, but optical encoders are available for high precision.
Yes, 3-channel (A/B/Z) encoders are available upon request for absolute homing.
Yes, every sample is shipped with a flying-lead mating wire harness for immediate testing.
Output-side feedback can be reviewed when the package has enough space and the buyer defines repeatability, backlash, connector, and inspection requirements.
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.
