What should be included in the first RFQ email?

Include joint position, CAD envelope, peak and continuous torque or force, speed, duty cycle, voltage, protocol, encoder and brake expectations, prototype quantity, pilot forecast, and destination.

How quickly can we get an actionable response?

Most complete RFQs receive first-round engineering feedback and quote direction within one business day.

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
Joint and envelope	Hip, knee, ankle, shoulder, elbow, wrist, hand, or custom linkage; include CAD and drawing revision	Confirms whether a custom actuator package is physically manufacturable.
Load and motion target	Peak torque, continuous torque, speed, duty cycle, overload event, or linear force and stroke	Prevents sizing from peak torque alone and exposes thermal risk early.
Interface and electronics	Flange, hollow shaft, cable exit, voltage, protocol, encoder, brake, and driver location	Avoids actuator samples that fit mechanically but fail controls, routing, or assembly.
Program stage	Prototype, EVT, DVT, pilot quantity, annual forecast, and target schedule	Aligns tooling, sample evidence, inspection scope, and lead-time planning.
Destination and terms	Country, Incoterm, requested ship date	Aligns packaging, documents, and shipping plan early.

What Happens After Inquiry

Engineering pre-check for actuator architecture and data completeness.
Quote direction with lead-time assumptions and risk notes.
Sample scope alignment, drawing freeze, and validation acceptance criteria.
Pilot 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: frame size candidate, torque at speed, electrical window.
Mechanical interface: shaft, flange, connector, drawing revision.
Commercial scope: prototype quantity, annual forecast, destination, 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.
for low-speed pulse and backlash boundary screening.
when your inquiry includes tracking, exposure drift, or mount retrofit constraints.

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.
