🔍 Key Concepts
• Compare the internal parts you see to the typical construction of a DC electric motor (armature windings, field coils, commutator, brushes).
• Think about how a sliding vane air motor is built (a rotor with slots and vanes running inside an off‑center cylinder, with air ports in the housing).
• Contrast this with radial vs. axial piston hydraulic motors (individual pistons arranged radially around, or along, the shaft with a swash plate or cam ring).
💭 Think About
• Look closely at part 26 inside housing 24: does it look like a wound armature with a commutator, or more like a smooth rotor with slots or pockets for vanes?
• Do you see any separate pistons, swash plates, or cam rings that would clearly indicate a hydraulic piston‑type motor?
• Are there any field windings, brushes, or electrical terminals that you would expect on an electric starter, or does the layout match more closely an air‑driven unit feeding a geared output?:
✅ Before You Answer
• Identify whether the rotor shows windings/commutator (electric) or slots/vanes (air).
• Check if there are discrete pistons arranged radially or axially; if not, be cautious about choosing a hydraulic piston option.
• Notice the gear train and housing ports and decide if they better fit an air motor or an electric/hydraulic design.
