So looking at various threads on dc gen sets like the aqua gen or the frankenmaster (sp?) or a dedicated ac genset, I wondered why not hook up both to a prime mover ?
Why couldn't you get a 12 to 15 hp kubota
diesel, hook up a PMG 3-5 KW
head to the crankshaft output on a
electric cluth for when you wanted ac
power, and have some big alternators like a 300 amp electrodyne on the front of the
engine with PTO's for
refrigeration and watermakers, all again on
electric clutches? When you just needed dc
power just disengiege the
generator and run the
alternator and the
watermaker or refrgation compressors?
What would be the major challenges to such a system? I expect regulation would be the most challenging for the ac side. But it seems more than possible to do this, no?
No one that I know of sells such a device. The aquagen is the closest thing but does't do ac power, and I would want that for the air conditioners.
This wouldn't be
cheap, when you add up the
engine, the
generator head, the
alternator, the refrig
compressor, and the
watermaker pump, plus wireing, and such. But it would be pretty cool.
This is the PMG head that I would consider...
PMG - High Power AC Permanent Magnet Generator - Designed for high reliability
Alternator
Electrodyne Alternators high output
The prime mover would/could be this...
Beta Marine US Ltd. Distributors for Kubota based marine diesel engines and generators for sailboats, yachts and trawler boats.
refrigeration compressor
ENGINE DRIVE
watermaker
pump
CAT PUMPS® On-Line - Product Selector: Select a Pump
I have room for this in the engine space depending on how much room the brackets would take. The PMG generator would be mounted in the rear coupled to the output shaft of the engine.
A smaller engine would
work as well. But the hp curve I would want would favor higher hp at lower
rpm.
Just not sure about the voltage regulation of the ac generator....
I xpect something like this using all new
parts to cost around 12K to 15K, including the related watermaker and refrigeration
parts. But am still pricing stuff.
Interesting stuff.
