marine generator is a compact, self-contained unit designed to produce electrical power on a boat or ship. Its primary function is to provide AC (Alternating Current) power for all non-propulsion electrical needs when away from shore power, effectively acting a floating power station.
Primary Applications & Uses
Marine generators are used to power the AC electrical system on a vessel
✔ Climate Control: Running air conditioning and heating systems is the most common reason for installing a generator on the ship.
✔ Galley Appliances: Powering microwaves, electric stoves/ovens, induction cooktops, refrigerators, freezers, blenders, and coffee makers.
✔ Comfort and Convenience: Operating water makers (desalinators), water heaters, washing machines, and dryers.
✔ Entertainment Systems: Running large entertainment systems, flat-screen TVs, gaming consoles, and sound systems throughout the boat.
✔ Battery Charging: While often done via a DC alternator, a generator can power a large battery charger or inverter/charger to rapidly replenish the house bank batteries that run DC systems (lights, pumps, navigation electronics).
✔ Tools and Workshop: On larger vessels and workboats, generators power workshops, dive compressors, cranes, and winches.
✔ Safety Systems: Powering critical systems like radars, emergency communications, and floodlights during extended voyages.
Advantages of Cummins Marine Generators
✔Cummins marine generator with standard Stamford alternator, with permanent magnet generator PMG excitation
✔Stamford with advanced automatic voltage regulator control (MX341), providing ±1.0% voltage regulation, it is used on marine generators as a standard configuration. This AVR has built-in protection against internal or external faults caused by persistent over-excitation. Cut off the excitation after a minimum of 5 seconds
✔Stamford 2/3 winding pitch suppresses excessive neutral current. 2/3 pitch winding can effectively eliminate the third harmonic of the voltage and the multiples of 3 harmonics. It is the best design for uninterruptible power supply equipment and other nonlinear loads. When it is connected in parallel with the power grid. This eliminates the excessive neutral current that sometimes occurs with larger coil pitches.
✔A fully continuous damping winding reduces oscillations when the generators are operated in parallel. The 2/3 pitch, pole and teeth are carefully matched to suppress the waveform distortion of the output voltage.
✔Single or double fulcrum structure and dynamically balanced rotor with sealed bearings
✔Standard IP23 protection level
