OEM ENGINEERING GUIDE
What to Include in an OEM Motor RFQ
A useful request for quotation gives engineering and purchasing the same starting point. Share what is known, mark what is provisional and leave genuinely unknown values open rather than filling them with guesses.
1. Start with the product and project stage
Describe what the final product does, where it will be used and whether this is a new design, a replacement or an update to an existing appliance. State whether you need a motor alone, a motor with electronics or a complete fan assembly.
If a catalog model is already of interest, include its full model and suffix. Otherwise, describe the application first. Separate prototype work, validation, pilot production and ongoing supply; these are different quotation contexts.
2. Prepare the core technical inputs
Use this checklist as a conversation aid, not a requirement to finalize every field before contacting a supplier.
| Input | What to provide |
|---|---|
| Electrical | AC or DC supply; voltage range; AC frequency; available current; existing controller details. |
| Operating point | Loaded speed and torque, or the load information currently available; separate startup and short-duration requirements. |
| Duty and environment | Run/rest sequence, starts, ambient temperature, enclosure and cooling; relevant dust or moisture exposure. |
| Mechanical | Available dimensions, shaft, mounting, coupling, rotation and viewing direction; connector and lead-wire needs. |
| Acceptance | Performance tolerances, validation method, noise target with measurement conditions, and documents required for the target market. |
These inputs allow engineering and purchasing teams to describe the same target. Provide confirmed values where available, acceptable ranges where flexibility exists, and mark genuinely unknown items as open questions.
3. Add the inputs specific to your product family
Universal motors
Confirm the AC voltage/frequency and control arrangement, the loaded operating point, duty cycle and required rotation reference. Do not substitute catalog no-load speed for the speed needed in the appliance.
Brushless motors
State whether the controller is included in the request or supplied separately. Describe available control signals and any feedback requirement. Share the intended motor/controller pairing if already defined; “brushless” alone is not a complete interface specification.
Fans and blowers
Specify required airflow at the required pressure, including units, rather than free-air flow alone. Describe the duct, filter, grille and installation constraints. The installed operating point depends on the fan characteristic and system resistance.
Scope note: These are preparation guidelines for different product families, not a statement that every family is currently listed or available from Zhanye. Confirm the requested product scope during the inquiry.
4. Separate technical needs from purchasing targets
List sample quantity, expected order quantity and estimated annual demand separately. Add the target sample date, intended production date and delivery destination. If useful, indicate a target cost and clarify what it should include.
Present these as requested terms, not assumed supplier commitments. MOQ, lead time, tooling, freight and sample charges need confirmation in the quotation. For replacement projects, identify which interfaces are fixed and which changes can be considered.
5. Send drawings with clear revision control
A dimensioned sketch is more useful than an unscaled product photograph. Name each file with the project or model and its revision. Label requirements as confirmed, preferred or to be determined, so a provisional target is not mistaken for an approved specification.
Only share files you are authorized to disclose. For confidential projects, agree the document-sharing process before sending detailed drawings. The current Zhanye RFQ form does not take attachments; send appropriate files by email to sales@zhanyemotor.com and use the same project name in both messages.
6. Copy this starter RFQ
Replace the bracketed prompts. Unknown values can be marked “TBD.”
Subject: OEM motor RFQ — [project / application] Application and project stage: [description] Product requested: [motor / motor + controller / fan] Candidate model, if any: [full model and suffix] Supply and control: [voltage, frequency, controller] Operating target: [speed + torque OR airflow + pressure] Duty and environment: [run/rest cycle, temperature, cooling] Mechanical interface: [dimensions, shaft, mounting, direction] Validation and documents: [criteria and target market] Sample / order / annual quantity: [separate estimates] Requested timing and destination: [dates and location] Drawing revision and open questions: [references / TBD]
After an initial review, align the configuration, unresolved technical points and validation plan before treating a quotation as a production specification. You can begin with fewer details and add information as the project develops.
