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.

RFQ Checklist Before You Send
| Required Item | Example | Why It Helps |
|---|---|---|
| Electrical window | 24V/36V/48V/60V bus, continuous current, peak current | Narrows viable GaN drive power stage and protection range. |
| Motor and encoder | BLDC/PMSM/frameless, pole pairs, BiSS-C/SPI/ABI/Hall | Confirms commutation, FOC tuning, and feedback interface fit. |
| Protocol and control | EtherCAT, CAN FD, CANopen, torque/velocity/position mode | Aligns firmware, commissioning files, and diagnostics. |
| Board envelope | OD/ID, stack height, mounting holes, connector direction | Avoids joint-module interference and harness rework. |
| Quantity plan | Prototype, EVT/DVT/PVT, pilot batch, annual forecast | Improves lead-time and pricing accuracy. |
| Destination and terms | Country, documentation needs, 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
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.
- Electrical Window: DC bus voltage (24V/36V/48V/60V) and continuous/peak current targets.
- Motor Specs: BLDC/PMSM/Frameless, KV, pole pairs, and phase resistance/inductance.
- Feedback & Control: Encoder type (BiSS-C, optical, magnetic), control mode (torque, FOC), and communication protocol (EtherCAT, CAN FD).
- Mechanical Envelope: Diameter, stack height, thermal cooling method (air/conduction), and potting needs.
- Commercial Scope: Prototype quantity, EVT/DVT schedule, annual forecast, 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 drive architecture against voltage, current, motor, encoder, and board-envelope 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. |
