1 Identity-Giving FunctionFunção Identitária
Function class
ActuationFunction ⊑ DesignedFunction
Realized in
ActuationProcess ⊑ PlannedProcess
All definitions converge on actuators converting energy into motion/movement. This energy-to-kinetic-motion conversion is the identity-giving function that makes an actuator an actuator, regardless of whether it's pneumatic, hydraulic, or electric.
2 Genus DeterminationDeterminação do Gênero
Assemblybfo:Object (BFO_0000030)
Actuators are causally unified artifacts with physically connected components (housing, moving parts, energy conversion mechanisms) that work together as a single unit. They are more complex than simple MaterialArtifacts. None of the parent candidates (FunctionalObject, general instrument, Artefact) are appropriate domain-specific classes in our ontology. Assembly is the correct IOF-Core root for engineered artifacts with removable subcomponents.
3 Differentia SpecificaDiferença Específica
∃bearerOf.ActuationFunction

An actuator is distinguished by bearing an actuation function that converts energy from an external source into kinetic motion.

The ActuationFunction is the minimal and necessary differentiating condition. It captures the essence of energy-to-motion conversion that all actuator definitions emphasize, distinguishing actuators from other energy conversion devices.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These are the universal components present in all actuator types - something to convert energy and something to produce motion output.
