Marine motor windings are insulated coils within electric motors that generate electromagnetic fields for propulsion or auxiliary systems. Refrigeration systems on marine vessels use compressors, condensers, and evaporators to maintain temperature control for cargo or onboard spaces. Both systems require robust materials and maintenance to withstand harsh marine environments.

Marine Motor Windings:
Size: Varies by motor power (typically 0.5mm to 5mm wire diameter)
Grade: Class H (180°C) or Class F (155°C) insulation
Material: Copper or aluminum conductors with enamel or polymer insulation
Viscosity: N/A
Buoyancy: N/A

Refrigeration Systems:
Size: Varies by capacity (small: 1-5 HP, large: 10+ HP)
Grade: R-134a, R-404A, or R-22 refrigerants
Material: Copper tubing, aluminum fins, steel/compressor housing
Viscosity: Refrigerant-specific (e.g., R-134a: 0.20 cP at 25°C)
Buoyancy: N/A
