Magnets and motor components for civil UAVs

Begin with a controlled component specification

Identify the civil use and the part to be sourced. Provide the approved drawing revision, material requirements and inspection plan, or identify which documents are still being developed. A request for an interchangeable component needs the same defined acceptance basis as a new part.

EMTXI coordinates sourcing rather than aircraft or propulsion design. We do not infer a component specification from a vehicle name. If the enquiry covers magnets together with stators, shafts, housings or rotor assemblies, use a bill of materials that identifies the drawing and approval status for each item. Motor component kits describes how that scope is separated in the quotation.

Make the qualification record explicit

Distinguish samples for incoming inspection from parts intended for the developer's subsequent assembly and qualification work. Define the measurements and documents required from the component producer, the acceptance criteria and the organisation responsible for each approval. A quotation should identify any record that the proposed route cannot yet provide.

The customer retains responsibility for the suitability and approval of the complete aircraft and its operation. For eVTOL or other programmes with additional assurance requirements, provide the required qualification and document-control framework at enquiry stage. A magnet or motor-part order does not demonstrate that those requirements have been met.

Assess origin with supporting documents

Where a programme restricts sourcing origin, state the rule as a procurement requirement and identify the stages it covers. Final machining or assembly location alone does not establish the origin of upstream material. Our origin-traceability process separates available evidence, supplier declarations and unresolved gaps for buyer review.

The same discipline applies to changes after sample approval. An alternative producer or processing location is a proposed change requiring assessment against the programme's agreed acceptance requirements, not an automatic substitution.

Prepare samples and programme releases

• Identify the civil application and the component scope.

• Supply controlled drawings and a bill of materials where relevant.

• Define sample quantities, inspection records and approval responsibilities.

• State origin-document requirements and delivery destinations.

• Separate forecast demand, firm releases and target dates.

• Agree lot identification, packaging and change notification.

We use these inputs to assess prototype supply and a subsequent volume programme. Available capacity, lead time and the supplied documentation are confirmed for the proposed route and order; they are not assumed from the programme forecast.
