Sample Acceptance Plan

Turn Product Selection Into Pass/Fail Checks

Before a motor family becomes a sample order, sales engineering converts the RFQ into acceptance checks for engineering, procurement, and quality. These checks keep CAD/STEP release, prototype approval, and repeat production tied to the same specification baseline.

CAD / STEP Request

Request Outline Drawings Before You Freeze the Mechanical Design

Share the mating envelope and target duty data so sales engineering can confirm whether an existing outline drawing, STEP/IGES file, or custom shaft and flange proposal is suitable for your project.

1

Installation envelope, mounting pattern, shaft interface, and cable exit.

2

Voltage, loaded speed, torque, gear ratio, duty cycle, noise, and backlash limits.

3

Preferred CAD format, drawing revision, prototype quantity, destination, and compliance notes.

Fields engineering checks before sharing a model

Product fit
Diameter, gearbox length, motor family, shaft style, flange pattern, and cable or connector exit.
Performance target
Voltage, loaded speed, continuous torque, peak or stall torque, ratio, duty cycle, life, noise, and backlash.
Mechanical interface
Mating drawing revision, installation clearance, radial or axial load, tolerance priority, and assembly sequence.
Release package
2D outline, STEP/IGES envelope, custom shaft/flange review, datasheet values, and quality evidence scope.

Useful before CAD freeze

Estimate ratio and torque firstCompare POM, hybrid, and metal gearsAlign quality evidence scope
Email CAD requestWhatsApp engineeringOpen CAD request form

CAD files are shared by project fit and revision status. For custom shafts, flanges, cable routing, or gearbox interfaces, attach the mating drawing so the first CAD exchange uses the correct mechanical boundary.

RFQ Checklist

  1. 3D CAD of installation space
  2. Target system performance (load, speed)
  3. Connector and wiring harness requirements
  4. Feedback requirement: encoder, Hall, or no feedback
  5. Prototype acceptance tests and annual production quantity
  6. Required labels, packaging, and export document scope

Risk Controls

  • Interface mismatch: We validate the final assembly against your actual mating parts and system test fixtures.
  • Spec drift between engineering and purchasing: Each sample build is tied to a drawing revision, BOM option list, and RFQ requirement baseline.
  • Supplier split across motor, gearbox, encoder, and cable: We consolidate drive module records so one coordinated build record tracks fit, function, and final inspection.
  • Prototype assembly cannot be repeated at production volume: Assembly fixtures, cable routing, drawing revision, EOL limits, and packaging instructions are frozen before pilot release.

Buyer FAQ

Do you handle custom cables and connectors?

Yes, we source and integrate specified connectors (JST, Molex, TE, etc.) and define continuity checks for the approved harness.

Can you build around our housing or latch mechanism?

Yes. Send 3D CAD, mating part drawings, cable routing limits, and the required installation sequence for review.

How are custom assemblies validated before production?

Prototype approval usually combines dimensional checks, torque-speed testing, current/noise review, and the buyer-defined fixture test.

What is the best starting point for a custom drive module?

Start with the installation CAD, load and speed target, voltage and driver limits, shaft interface, connector requirement, sample test method, and expected annual quantity.
