Sample Acceptance Plan
Turn Product Selection Into Pass/Fail Checks
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
Build the Ratio Table Before Sample Approval
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. |

CAD / STEP Request
Request Outline Drawings Before You Freeze the Mechanical Design
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.
1
Installation envelope, mounting pattern, shaft interface, and cable exit.
2
Voltage, loaded speed, torque, gear ratio, duty cycle, noise, and backlash limits.
3
Preferred CAD format, drawing revision, prototype quantity, destination, and compliance notes.
Fields engineering checks before sharing a model
- Product fit
- Diameter, gearbox length, motor family, shaft style, flange pattern, and cable or connector exit.
- Performance target
- Voltage, loaded speed, continuous torque, peak or stall torque, ratio, duty cycle, life, noise, and backlash.
- Mechanical interface
- Mating drawing revision, installation clearance, radial or axial load, tolerance priority, and assembly sequence.
- Release package
- 2D outline, STEP/IGES envelope, custom shaft/flange review, datasheet values, and quality evidence scope.
Useful before CAD freeze
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.
RFQ Checklist
- Required Pulses Per Revolution (PPR)
- Target positioning accuracy
- Connector type and pinout
- Logic voltage, output channel type, and cable length
- Whether feedback is required on motor shaft or output shaft
- Backlash, homing, and repeatability test method
Risk Controls
- Signal interference (EMI): Use shielded cables and proper grounding in the wiring harness.
- Pulse jitter at low speeds: We tune the magnetic pole clearance and use high-grade Hall ICs to ensure clean square waves.
- Vibration induced disconnects: All encoder PCBs are conformal coated and use locking JST/Molex connectors.
- Motor-side feedback hides gearbox lost motion: For precise output positioning, backlash, mounting stiffness, homing logic, and optional output-side sensing are reviewed together.

Buyer FAQ
What types of encoders do you use?
We typically use magnetic Hall-effect encoders for robustness against dust and oil, but optical encoders are available for high precision.
Can I get a Z-index pulse?
Yes, 3-channel (A/B/Z) encoders are available upon request for absolute homing.
Do you provide the mating connector?
Yes, every sample is shipped with a flying-lead mating wire harness for immediate testing.
Can encoder feedback be placed on the gearbox output?
Output-side feedback can be reviewed when the package has enough space and the buyer defines repeatability, backlash, connector, and inspection requirements.
