ISO 15926 defines it as a WINDING on the stator — an assembly of interconnected turns 'intended for common operation'. In a machine that common operation is generating the stationary electromagnetic field.
2 Genus DeterminationDeterminação do Gênero
MaterialArtifactbfo:Object (BFO_0000030)
ISO 15926 types WINDING as an ARTEFACT and an ELECTRICAL CONDUCTOR; MaterialArtifact is the corresponding IOF root.
3 Differentia SpecificaDiferença Específica

A material artifact that is an assembly of interconnected conductor turns mounted on the stator of a machine, bearing an electromagnetic field generation function.

Constructive and positional: 'a winding on the stator'. The same winding construction on a rotor is a rotor winding, so position is essential and the axiom is necessary-only.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

No sub-component is named in any source definition for this term. validate_necessary_parts_quotes() requires a verbatim source_quote for every part, and there is nothing to quote — so no parts are asserted (ODR-022 §10.2).
