Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
ActuationFunction ⊑ DesignedFunction
Realized in
ActuationProcess ⊑ PlannedProcess
Reusing ActuationFunction from the already-enriched 'actuator' class since rotary actuator is a constructive subtype of actuator with the same identity-giving function - the function to convert control signals into mechanical motion.
2 Genus DeterminationDeterminação do Gênero
actuatorbfo:Object (BFO_0000030)
The ISO 15926-4 definition explicitly states 'A ROTARY ACTUATOR is an ACTUATOR', and 'actuator' is already enriched in our ontology as an Assembly with ActuationFunction. This is the most specific appropriate superclass.
3 Differentia SpecificaDiferença Específica
∃participatesIn.RotaryMotionProcess

Causes specifically rotary motion rather than linear or other motion types.

The ISO definition specifies 'causing a rotary motion' as the key distinguishing feature. Since the genus actuator already provides the basic actuation function, the differentia must capture the rotary motion characteristic that distinguishes this from linear actuators, oscillating actuators, or multi-axis actuators.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

No component terms are provided in the Known Component Terms list, and the source definition is too high-level to identify specific necessary parts beyond what the genus actuator would already provide. Any specific parts (motor, gears, output shaft) would be subtype-specific depending on the particular rotary actuator design.

TransformationTransformação
input control signal and energy converted into controlled rotational motion with specified torque and angular positioning
The rotary actuator takes control signals and converts them into mechanical rotational output. This signature distinguishes it from pumps/compressors (which act on fluids) and from linear actuators (which produce linear rather than rotational mechanical output).
