Axiomatization Decision Log
1
Identity-Giving Function
Function class
PneumaticMotorFunction
⊑ DesignedFunction
Realized in
PneumaticEnergyConversionProcess
⊑ PlannedProcess
The identity-giving function is the conversion of compressed gas energy (typically air) into mechanical energy. This is a specific subtype of mechanical energy generation that uses pneumatic power as the energy source, distinguishing it from electric motors, hydraulic motors, or combustion engines.
2
Genus Determination
Motor
The genus 'motor' is the most specific appropriate superclass, as indicated in the parent candidates and already enriched in our ontology with function MechanicalEnergyGenerationFunction. This is more specific than 'Assembly' or 'MaterialArtifact' and captures the shared characteristic of all motors - mechanical energy generation. The ISO 15926 hierarchy also indicates AIR MOTOR as immediate parent, but 'motor' is the enriched genus available.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
These parts represent the minimal necessary components for any pneumatic motor: gas input interface, containment structure, and mechanical output interface. Specific internal mechanisms (pistons, rotors, turbines) vary by subtype and should be modeled at subtype levels.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfGas
— pressurized, typically air
Outputs (O)
PortionOfGas
— lower pressure exhaust gas
Transformation (T)
pneumatic energy converted to mechanical rotational energy
Pneumatic motors consume compressed gas and convert its pressure energy into mechanical rotation, exhausting expanded gas at lower pressure. This signature distinguishes them from other motor types and enables compatibility reasoning.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Disjointness Axioms
electric motor
C4: electric motor. Different energy sources (compressed gas vs electricity vs pressurized liquid) create incompatible input signatures and energy conversion processes
Cross-Standard Observations
All three sources provide consistent functional definitions emphasizing compressed gas (typically air) as the energy source. ISO 15926 provides hierarchical context with AIR MOTOR as parent. Subtypes indicate both rotary and reciprocating mechanisms are possible.
