Datasheet fit check
Voltage, speed, torque, current, thermal, and life targets.
Compact brushless DC motors for OEM devices that need longer life, lower acoustic noise, stable speed, and tighter electrical control than brushed micro motors.
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 OEM engineers replacing brushed micro motors or sourcing compact brushless modules for repeat production.
Validate Before Sampling
RFQ Data That Changes the Quote
| Stage | Buyer Input | Factory / QC Checkpoint | Decision Output |
|---|---|---|---|
| RFQ feasibility review | Target diameter and maximum length; Rated voltage, target RPM or KV, load torque, and current limit | Match diameter, length, voltage, speed, and load to the product envelope | Feasibility notes, missing parameters, and sample direction. |
| Sample definition and validation | Noise target in dBA, duty cycle, and lifetime target; Shaft, flange, bearing, cable, connector, and feedback requirements | Diameter class: 4 mm to 36 mm outside diameter, project-specific length | Controlled sample scope with measurable acceptance criteria. |
| Pilot lot and repeat production | Pilot quantity, annual forecast, revision baseline, and destination | Thermal runaway from matching peak torque to continuous rating: Calculate RMS torque ($T_{RMS}$) over the full duty cycle. Never size a motor solely by peak acceleration load. | Pilot records tied to acoustic noise (nvh) and outgoing inspection. |
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Diameter class | 4 mm to 36 mm outside diameter, project-specific length | Defines the mechanical envelope, stator volume, and maximum continuous thermal dissipation ($T_{th}$). |
| Acoustic Noise (NVH) | Project-specific dBA target at defined distance/load | Supports user comfort, device perception, and documented validation planning when test conditions are defined. |
| Dynamic Balancing | ISO 1940-1 G1.0 or G0.4 for speeds > 10,000 RPM | Prevents high-frequency vibration from destroying precision bearings and transmitting resonance. |
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.
Yes. Send the reference model, drawing, application load, target life, and quantity forecast so engineering can check feasible changes.
Noise and lifetime data should be quoted with test conditions, load profile, and acceptance criteria. Project-specific validation can be arranged.
