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
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.
CAT PUMPSŪ 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.
