| Quote currency | USD | Export quotations are usually discussed in USD unless a buyer requests another quotation currency. |
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 |
|---|---|---|
| Lifespan | 10,000+ hours | Important when maintenance access is limited in industrial or regulated device programs. |
| Maximum Speed | Up to 15,000 RPM (Motor) | Allows higher reduction ratios to be used while maintaining reasonable output speeds. |
| EMI Generation | Low with suitable driver and wiring | Important for RF-sensitive monitoring equipment and telemetry. |
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 compact BLDC | 6-24V BLDC | 5:1-1000:1 | High-speed motor baseline; confirm Kv and driver | Driver-limited output RPM after load review | 100 g.cm-1.5 kg.cm reference window | Controller current limit defines peak event | Driver, ratio, and stage count dependent | Medical pumps, compact robots, instruments |
| 16/22mm continuous-duty BLDC | 12-24V BLDC | 4:1-1500:1 | Up to 15000 RPM motor reference by platform | Set by ESC, load, thermal rise, and ratio | 0.5-5.5 Nm reference window | Peak torque must be current and time limited | Higher than brushed route when duty cycle is high | Robotic joints, pumps, industrial axes |
| 36/42mm BLDC gearmotor | 24-48V BLDC | 3:1-512:1 | Motor speed selected from wheel or actuator target | Validated on continuous load and enclosure heat path | 9.3-35 Nm reference window | Driver protection and shaft support required | Best fit for sustained duty and battery runtime | AGV drive, mower drive, heavy 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 |
|---|---|---|---|
| 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
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 can provide built-in controller options for simple speed control, or integrate with your external controller.
For applications that need very low cogging torque, slotless BLDC options can be reviewed against space, cost, and control requirements.
Standard is IP40, but we can seal the gearbox and motor housing up to IP65 for harsh environments.
Freeze the voltage range, target speed and torque, duty profile, driver type, control signal, Hall or encoder requirement, connector pinout, and thermal acceptance limits.
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.
