Datasheet fit check
Voltage, speed, torque, current, thermal, and life targets.
Ultra-light micro BLDC motor sourcing for FPV whoops, micro UAV propulsion, compact gimbals, and weight-sensitive drone assemblies where KV, thrust, efficiency, heat, and balancing must be validated as one system.
Controlled technical documents
Public generic files can mislead OEM selection when winding, bearing, connector, test fixture, or acceptance criteria are still open. Technical documents are shared after model, revision, NDA, test condition, and destination scope are confirmed.
No placeholder certificates, stock proof photos, or generic public CAD downloads are published from this request block.
Voltage, speed, torque, current, thermal, and life targets.
Shaft, flange, connector, cable, and assembly interface.
Noise, load, vibration, endurance, and inspection records.
Best-fit buyer
Best for FPV, UAV, and compact hardware teams that need a lighter motor family with repeatable winding, balancing, cable, and mounting details for production.
Validate Before Sampling
RFQ Data That Changes the Quote
| Stage | Buyer Input | Factory / QC Checkpoint | Decision Output |
|---|---|---|---|
| RFQ feasibility review | Target motor size class, weight limit, mounting pattern, shaft, and propeller; Battery voltage, ESC, target KV or loaded RPM, current limit, thrust or airflow target | Match KV target to battery voltage, propeller, ESC, current limit, and thermal margin | Feasibility notes, missing parameters, and sample direction. |
| Sample definition and validation | Duty profile, cooling airflow, ambient temperature, balancing expectation, and vibration limit; Lead wire length, connector, winding revision, pilot quantity, annual quantity, and packaging requirement | Weight and size class: 0802, 1002, 1102, or custom micro outrunner envelope after drawing/sample review | Controlled sample scope with measurable acceptance criteria. |
| Pilot lot and repeat production | Pilot quantity, annual forecast, revision baseline, and destination | KV-only sourcing creates overheating samples: Evaluate loaded RPM, propeller, thrust, current, winding temperature, ESC settings, airflow, and duty cycle before production winding lock. | Pilot records tied to kv, thrust, and efficiency and outgoing inspection. |
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Weight and size class | 0802, 1002, 1102, or custom micro outrunner envelope after drawing/sample review | Small airframes are limited by grams, mounting pattern, prop clearance, and battery draw before catalog RPM alone matters. |
| KV, thrust, and efficiency | Project-specific KV with thrust grams, current, watts, and efficiency measured by propeller and voltage | A high KV claim does not confirm useful thrust or flight time unless the propeller, ESC, battery, and heat data are attached. |
| Lamination and high-speed losses | Thin lamination options such as 0.10 mm reviewed only when material and tooling scope are confirmed | High electrical frequency can create losses and heat that reduce efficiency in small high-KV motors. |
Requestable Evidence Pack
Use this evidence package to keep motor claims connected to load, fixture, controller, drawing revision, and acceptance criteria before sampling or production release.
RFQ note
Do not treat quiet, long-life, efficient, or compliant as a generic claim. Confirm the measured condition, buyer fixture, sample lot, and acceptance rule for this program.
Locks the motor envelope, voltage, speed, load, shaft, connector, and revision basis before quote comparison.
Keeps current, speed, torque, power, and temperature claims tied to the real test condition.
Prevents low-noise claims from being detached from fixture, distance, controller, load, and device resonance.
Turns long-life wording into hours, cycles, environment, load, and failure criteria that can be reviewed.

Use when you need a quick document-scope check before a full RFQ.
Target KV can be reviewed when battery voltage, ESC, propeller, current limit, thrust target, mounting, wire length, weight limit, and expected annual volume are provided.
Thrust and efficiency data should be generated with the agreed voltage, propeller, ESC, airflow, sample count, and temperature method so buyers can compare samples fairly.
