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 |
|---|---|---|---|
| Driver and commutation | Will the BLDC motor work with the intended controller, hall logic, and startup profile? | Driver model, supply voltage, phase current limit, hall requirement, speed control mode, and wiring diagram. | Startup, speed regulation, direction, and protection behavior pass on the target controller. |
| Continuous thermal window | Can the motor run the required duty without thermal shutdown or life reduction? | Continuous load, ambient temperature, mounting heat path, duty cycle, and allowed temperature rise. | Case temperature and current settle below the approved limit during loaded endurance testing. |
| Ratio and output interface | Does the selected gear ratio keep speed, torque, backlash, and shaft load balanced? | Output RPM, torque reserve, radial load, shaft drawing, backlash target, and gearbox stage count. | Loaded RPM, output torque, and mechanical fit pass before CAD or STEP files are released. |
| Signal and EMI review | Will the motor, driver, and cable layout avoid noise problems in the final device? | Cable length, shielding plan, nearby sensors, EMC constraints, connector type, and grounding scheme. | Speed feedback, telemetry, and nearby electronics remain stable during motor operation. |

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
- Provide nominal voltage and load
- State required lifespan (hours)
- Specify driver requirements (built-in or external)
- Define speed-control signal, Hall output, and connector pinout
- Share duty profile, ambient temperature, and cooling path
- State sample quantity, reporting needs, and annual demand
Risk Controls
- Thermal shutdown: Ensure adequate heatsinking and match nominal current strictly through proper ESC programming.
- Bearing fatigue: Bearing type and grade are selected against the target life, radial load, and duty profile.
- Controller mismatch: Integrated controller options can be matched to the motor's Kv rating during integration review.
- Driver tuning hides thermal or noise problems until late testing: Controller mode, current limit, speed loop, PWM behavior, and heat path are reviewed with the load profile before sample sign-off.

Buyer FAQ
Do you provide the BLDC controller?
We can provide built-in controller options for simple speed control, or integrate with your external controller.
Can you provide slotless BLDC motors?
For applications that need very low cogging torque, slotless BLDC options can be reviewed against space, cost, and control requirements.
What is the IP rating?
Standard is IP40, but we can seal the gearbox and motor housing up to IP65 for harsh environments.
What must be defined before BLDC samples are built?
Freeze the voltage range, target speed and torque, duty profile, driver type, control signal, Hall or encoder requirement, connector pinout, and thermal acceptance limits.
