Marine Generator / Alternator · Power Generation
The Stamford/Cummins HC4 is a 150 kVA, 440 V, 50 Hz diesel‑driven marine generator set designed for auxiliary power on medium‑size vessels, featuring a compact IP23 enclosure and Class H insulation. As an Alternator, it is normally installed in the engine room or generator space, mechanically coupled to a diesel engine, turbine, shaft drive or other prime mover. In that role, its primary purpose is to convert mechanical power into three-phase electrical power for the shipboard distribution system. Alternator variants differ in frame size, voltage, frequency, excitation and cooling, but all depend on winding insulation, bearings, excitation and stable prime-mover speed. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
What our service work and the manufacturer documentation say about keeping this model running.
Inspect winding cleanliness, insulation condition, bearings, cooling air path, terminals, excitation equipment and signs of overheating. Trend insulation, vibration and winding or bearing temperatures and review AVR or protection alarms. Verify voltage and reactive-load behaviour during normal operation. Refer to the manufacturer documentation for the exact figure for insulation, bearing, excitation and electrical limits.
Carry AVR or excitation modules where supported, rotating-diode sets, bearings, temperature sensors, fuses, terminal hardware and approved cleaning or insulation-maintenance materials.
