What should be included in the first RFQ email?

Include frame size candidate, torque at target speed, current/voltage window, interface drawing revision, quantity plan, and destination.

How quickly can we get an actionable response?

Complete RFQs make it faster to return first-round engineering feedback, quote direction, and clarification items.

Can we discuss custom OEM requirements before PO?

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

Duty Cycle / Operating Profile

Helps separate peak torque from continuous output and thermal design assumptions.

Target Torque (N·m)

Target Speed (RPM)

DC Bus Voltage (V)

Current Limit (A)

Max Envelope (OD x Axial Length)

Preferred Cooling

Controller / Feedback Requirement

Include controller model, sensor type, brake need, or tuning constraints if they are already known.

Prototype / Mass Production Qty

Delivery Location / Destination

Drawings / Reference Sample

Reference files help us check airgap, shaft/flange interface, winding limits, and validation scope faster.

RFQ Checklist Before You Send

Required Item	Example	Why It Helps
Target motor family	Frame size / torque class / closed-loop	Quickly narrows viable models and quote range.
Torque at speed	1.2 N·m at 600 RPM	Prevents over-reliance on holding torque only.
Voltage and current limit	72 V DC bus, 180 A peak phase current	Aligns winding, back EMF, inverter, and thermal assumptions.
Mechanical interface	Shaft, flange, connector drawing revision	Avoids sample mismatch and assembly rework.
Cooling and environment	Forced air, liquid jacket, oil, ambient temp, IP target	Separates peak torque from sustainable continuous output.
Quantity plan	Prototype qty + annual forecast	Improves lead-time and pricing accuracy.
Drawings or reference sample	STEP file, torque-speed map, current motor model	Speeds up airgap, shaft, flange, and validation review.
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: 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.
Attachments or references: drawing revision, torque-speed map, current motor sample, or target test report format.

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.
AFPM Quality Validation for torque-speed, thermal, resistance, insulation, balance, and outgoing record expectations.
AFPM Stator and Rotor Assemblies when your inquiry is for build-to-print subassemblies, replacement modules, or component-level sourcing.

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.
