RFQ Preparation Checklist

A complete RFQ lets the factory review design feasibility, sample scope, tooling need, test records, and export planning in one pass. If some values are not frozen, say so explicitly.

1. Target outside diameter, inside diameter, stack length, and available mounting envelope.
2. Continuous torque, peak torque, target speed, duty cycle, and expected motion profile.
3. DC bus voltage, current limit, cooling method, ambient temperature, and insulation requirement.
4. Lead wire, connector, Hall, encoder, resolver, or bare motor integration requirements.
5. Prototype quantity, annual forecast, target delivery country, and requested timeline.

Risk and Mitigation

The goal is to expose preventable risk early: unclear drawings, untested thermal assumptions, changing sample requirements, or production records that were requested too late.

• Ambiguous custom requirement: Start with the RFQ checklist and mark unknown items explicitly.
