Semi-formal axiom (Aristotelian)
Axiom type
LLM classification basis: structure-based → ⊑
Electric actuator is primarily defined by its physical mechanism - electric energy conversion to mechanical movement. While it shares the basic ActuationFunction with all actuators, its identity is distinguished by the electrical energy conversion mechanism, not by a unique functional role that differs from other actuator types.

COPI-Core operation
⚠ Process parent
PlannedProcess reaches no COPI-Core operation, and no gap (out of scope / coverage gap) is recorded.
LLM rationale:
Electric actuators share the same identity-giving function as all actuators - to produce specified movement or positioning. The electrical energy source is a mechanism differentia, not a distinct function type.

Genus (genus proximum)
Most specific superclass — may be a domain class like "Valve" or an IOF-Core root.
BFO/IOF-Core Root
bfo:Object branch
bfo:ObjectAggregate branch
bfo:ImmaterialEntity branch
LLM rationale:
Actuator is the most specific appropriate superclass and is already enriched in our ontology. Electric actuator is clearly a subtype of actuator, distinguished by its electrical energy conversion mechanism. The parent_candidates list includes 'actuator' which is the correct choice over the more general categories like INSTRUMENTATION ITEM or ELECTRICAL APPARATUS.

Conditions that distinguish
Electric Actuator
from sibling classes under genus
Actuator.
Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
The differentia captures the essential distinguishing characteristic - the electrical energy conversion mechanism and electrical signal input requirement. This is what makes an electric actuator different from pneumatic, hydraulic, or manual actuators under the same genus.

Necessary Parts
✓ done
no necessary parts
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
These parts are necessary for any electric actuator to function: energy conversion capability, electrical interface, and protective housing for electrical components.

Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
Electric actuators transform electrical input signals and power into controlled mechanical movement, which is the fundamental process signature that distinguishes them from other energy conversion types.
