electrical generator - out of an electrical trolling motor???
 

Is it possible to make a electrical generator - out of an electrical
trolling motor - to be used on a sailboat?

Do these trolling motors have permanent magnet motors?

Any advice on RPM's, voltage regulation, amp output, etc.....

The alternative is to use the bottom unit of an outboard and config.
it to a PM motor.

Anyone have any ideas or suggestions -URL links?

Or any alternative method for a electrical water powered generator for
crusing a la homemade.....

Thanks,

It's so easy you'll just be sick:

The rotors are made by gluing strong magnets to an old car disk brake
rotor, still on its bearings. The coils are hand wound pancake coils
placed sorta-close-to these rotating magnets, but not too close or it'll
stall it. 3,000 watts of rectified DC output is pretty simple, but your
rotating propshaft internal or dragged behind the boat, won't produce as
much power as their home-made wooden rotors do.

Notice how SLOW their alternators turn....no noisy gear trains, no belt
drives, no pulleys.....

I can just see an old brake rotor spinning behind the sternrail on its long
shaft trailing out behind your sloop, its copper stator coils shining in
the sunshine against the sea.....(c;

The guys whos webpage this only have a few complaints, one of which is what
to do with SO MUCH FREE POWER!

Thanks for the link Larry....I have also read Hugh Piggot of
Scorecraig Scotland....

What about the trolling motor idea.....? is it a PM motor? Do you
think it can be done? I like the Duogen of england concept but it
just too pricey.....

Larry I have followed your posts for sometime and usually been well
entertain and informed,,,,,

Thanks

I figure the ele. trolling motor has to be a PM motor otherwise it

Now the question is what RPM and what about voltage regulation.....

I believe that is the case. But the prop pitch is quite wrong for a
turbine.

Water moving horizontally at 10 knots equals about a 4 foot static head
pressure. If you figure out how to economically generate power from that,
get a patent, because there is endless tidal energy available at that
differential.

May '05 Australia doing the Tasman crossing figured they use 3X more

An I think that making power on passage is more vital than when at
anchor, radar, autopilot, navlights, etc.

Towed water gennys, even if just the prop to a rail mounted genny just
has too many issues.

The idea of a trolling motor as a water gen "may" have potential or a
homebrew version there of.

There is only about 3 feet of head available at the site, and the

A while back, one of our neighbors constructed a water wheel generator

How much power can you generate?
The amount of power available depends on the dynamic head, the amount
of water flow and the efficiency of the turbine/generator combination.
To get an idea about available power in watts, multiply the head in
feet, times flow in GPM, times 0.18 times efficiency. Turbine
efficiency ranges from 25% to 50%, with higher efficiency at higher
heads. To get a rough idea, use 0.30 (representing 30%) as a
multiplier for efficiency.

The pressure at the lowest point of a pipeline is equal to 0.433 times
the vertical distance in feet, called head.

Subject: Bike powered alternator to charge
The very-fast-turning car alternator is the wrong one.....

Aboard "Lionheart", a French-made Amel Sharki 41' cruising ketch, one
of the ways we recharge its two banks of 700AH batteries is with a
"shaft alternator". This slow-turning alternator puts out about
20-25A of DC when turned by the free-wheeling driveshaft as the
sailboat's prop is dragged through the water at about 8-11 knots by
the sail power. These alternators are designed to run MUCH slower
than car alternators, and probably more important to the poor pedaler,
they are more efficient, designed to run off minimal drive power that
is available. Here's a good article on shaft alternators your bike
would have no problem powering, right off the pedaled wheel:

http://www.sailnet.com/collections/a...eid=ouread0028

We also use a Windcharger, a solar panel on the cockpit's hard top,
and 70A and 125A alternators driven by the Perkins 4-108 4-cyl 50hp
main propulsion diesel engine.

Power-R-Us to run radar, chart plotters, computers, lighting, water
pumps, bilge pumps, microwave oven, fans, and an extensive electronics
navigation suite I've installed since bringing her to Charleston from
Satellite Beach, FL.

I just got through installing an 802.11b wireless broadband router to
interface the computer with the NMEA data network without dragging a
cable around the boat. You can lay in your beanbag on deck and
navigate with the software on the laptop....(c; THIS is livin'!

What make and type of shaft alternator do you have? Did you make any
mods to it?
I know of Canadian company that makes mods to alternators for this
shaft type driven system, but mucho$$. Presently cant find the link.

A quote from someone (not me)
" All joking aside, I used an alternater from a 350 Chev engine (That
is
what the auto parts shop told me), big mistake and great learning
experience. I can pedal for about 2 minits with the alternater
spinning at just over 1800 RPM (it cuts in at 1340 RPM). "

If you have an outboard with this shaft system doesnt apply, but mods
to a small HP lower unit may work.

If you do a serch on electric boats is amazing what mods they make.

Heres a link to an alternator (car size) mounted to a outboard. Very
cool and great idea......

POWERMAX High Output Alternators charge batteries up to 5 TIMES FASTER
than standard alternators. This means drastically reduced engine
running time, saving fuel, engine wear, and noise. A standard
"automobile-type alternator is designed only to replace the minimal
engine-starting draw.

When you use an alternator what about the power it uses to energize
the "fields"? How many amps is that?

BTW thank for the effort.
