What should be included in the first RFQ email?

Include motor type, OD and length limits, voltage, RPM or KV, load torque, current or thermal limits, noise target and test distance, lifetime target, interface drawing, quantity plan, target price range, and destination.

How quickly can we get an actionable response?

Complete RFQs are routed for first-round engineering feedback and quote direction as the first response target.

Can we discuss custom OEM requirements before PO?

Yes. We encourage pre-PO engineering clarification to reduce prototype and mass-production risk.

RFQ Checklist Before You Send

Required Item	Example	Why It Helps
Target motor family	Micro BLDC / coreless / Hall / encoder / gear motor	Quickly narrows viable models and quote range.
Package and performance	OD 16 mm x 25 mm, 12 V, 18,000 RPM, 2 mNm	Connects the mechanical envelope with real load and speed.
Noise and lifetime target	<35 dBA at 10 cm, 5,000 h, 30% duty cycle	Keeps validation methods tied to measurable conditions.
Mechanical interface	Shaft, flange, connector drawing revision	Avoids sample mismatch and assembly rework.
Quantity plan	Prototype qty, annual forecast, and target FOB range	Improves lead-time and pricing accuracy.
Destination and terms	Country, Incoterm, requested ship date	Aligns packaging, documents, and shipping plan early.

What Happens After Inquiry

Engineering pre-check for model fit and data completeness.
Quote direction with lead-time assumptions and risk notes.
Sample scope alignment and validation acceptance criteria.
Production and delivery planning for approved programs.

Common Clarification Questions

Can I send a rough requirement before final drawings are ready?

Yes. Send your current assumptions first, then mark pending items clearly so we can return a provisional quote scope.

How should we handle engineering changes after sample approval?

Use a revision-controlled change request with effective lot and impact scope agreed by both teams.

Can we align on compliance files before mass production?

Yes. Please list required document types in the RFQ stage so they are included in validation and delivery planning.

Suggested First RFQ Email Format

If your team needs a fast start, use this structure in the first email. It improves quote precision and reduces clarification cycles.

Project background and application scenario.
Motor target: type, OD and length limit, voltage, RPM or KV, torque/load, current, and thermal limit.
Validation targets: noise dBA with test distance, lifetime, duty cycle, temperature, and environment.
Integration: shaft, flange, bearing, cable, connector, control, feedback, and drawing revision.
Commercial scope: prototype quantity, annual forecast, destination, target price range, and target ship date.

What You Should Review Before Sending RFQ

Products for architecture-level selection and model-family fit.
Solutions / Applications for scenario-specific constraints and validation priorities.
OEM Capabilities for design collaboration, quality controls, and delivery process.
Engineering Blog for practical checklists you can copy into buyer workflows.

Typical First Response Package

Output	Purpose	Buyer Action
Model and architecture direction	Narrow viable options against torque-speed and interface assumptions.	Confirm baseline model path before cost-detail discussion.
RFQ clarification list	Close data gaps that affect pricing and lead-time accuracy.	Return missing values and drawing references in one reply.
Validation recommendation	Define sample test scope and acceptance evidence for technical sign-off.	Align internal engineering and procurement gates before PO.
