Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
MechanicalEnergyGenerationFunction ⊑ DesignedFunction
Realized in
MechanicalEnergyGenerationProcess ⊑ PlannedProcess
The identity-giving function is the same as any motor - to generate mechanical energy. This function is already established in the enriched 'motor' class.
2 Genus DeterminationDeterminação do Gênero
motorbfo:Object (BFO_0000030)
The most specific appropriate superclass is 'motor' (already enriched with MechanicalEnergyGenerationFunction). All definitions consistently state this is 'a motor that...' The parent candidates include MOTOR from ISO15926, confirming this genus choice. Motor is more specific than Assembly or MaterialArtifact.
3 Differentia SpecificaDiferença Específica
∃participatesIn.HydraulicToMechanicalEnergyConversionProcess

A hydraulic motor is distinguished from other motors by converting hydraulic pressure energy to rotational mechanical energy using high pressure oil.

The hydraulic mechanism is the minimal differentiating condition. All definitions emphasize 'high pressure oil' as the energy source, which constitutes both the input medium and the conversion process type.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These parts define the essential hydraulic-to-mechanical energy conversion interface that every hydraulic motor must possess regardless of internal design variation.

TransformationTransformação
hydraulic pressure energy converted to rotational mechanical energy
Hydraulic motors have a distinctive signature of hydraulic fluid input at high pressure, hydraulic fluid output at lower pressure, and rotational mechanical energy output. This differentiates them from other motor types.
Disjoint WithDisjunto com
electric motor
C4: electric motor. Process signatures are incompatible: hydraulic motors require hydraulic fluid input while electric motors require electrical energy input and pneumatic motors require compressed air input.
