Selfrunning Waterpump-generator device runs 60 Watts lamp...

[666666]

Next question(S). What size is the orifice that the water comes out of?? My guess is .75 to 1".
Is the orifice a Venturi??
It looks to me like the Paddle is 14" in diameter and the large pulley with the belt is 18". Anyone have an opinion or better yet a way to figure this out with measurements of
Since we already have a reference of 18" for the large pulley can these measurements be determined from the video???
James: Do you know what the working principle of your device is?

Has anyone here looked at the capacitor setup. What I see is two dual electrolytic capacitors. What I see is one wire coming out of the generator going to the + side of the first capacitor and the minus side of the first cap going to the minus of the second capacitor and exiting from the + side of the second cap into the wire that goes to the plug receptacle. The other wire from the generator to the plug receptacle, has the same hookup??? It used to be a common practice to use electrolytic capacitors in a AC circuit with this hookup. I admit I let my imagination run a bit but you really can't see the hookup on the lower wire and it does look like these are dual electrolytic so I am making some assumptions. This is how hendershot used his capacitors in a AC circuit. I would like some input from anyone here with their thoughts on this. Also if these are motor run capacitors why are they in series and has anyone seen this done before. Normally capacitors are used in a generator/alternator to regulate voltage. This is not the case here.
If this is hooked up the way I think, does it tune the generator? Or the motor? Or both?
thanks

I think that there is even a bridge rectifier below the lamp.
My idea was that this is "self excited" AC generator - with rotor field build up by dc coil,
rectifier is used to get the rotor field, and the capacitors help to even that out.

Capacitors don?t regulate voltage - they are passive - not active components.
They can be used to store charge, buffer energy in times of overflow and release
them if needed. In case of asynchronous AC motors they are used to delay one
phase of the motor (if not using 3 phase motor) to help start up and to give direction.
A powersupply with rectifier and capacitor is called "unregulated" power supply.

Look at the video in high resolution full screen and use the stop button. There are only two wires going to the plug receptacle. Capacitors "are" used for voltage regulation just Google it.  "BUT" NOT in this case. Capacitors can be used for impedance matching. This is an elementry project for beginning electronic students where a 60cps power supply is put in series with an inductor in series with a capacitor in series with a lightbulb. When L, C, and R, are matched the light will light to full brightness the same as if there was no L no C and no R in the circuit. I did this 30 years or so ago. If I remember right I made a variable inductor 1/4 henry in series with 22 Microfarad in series with a lightbulb. To tune just slide the [core] of the inductor in and out of the inductor. I used a three inch PVC pipe wrapped with 1000 turns of 15 gauge magnet wire and a silicon steel laminate core. By sliding the core in and out, the light could be adjusted from no brightness to full brightness.
   Because the Capacitors are in series, Generator to caps to Motor, It appears that the caps are used for impedance matching. I think to do this properly the generator would have to be rewound or an adjustable inductor would have to be placed in series with at least one of the capacitors for best results.

What I can see in the picture is that 2 cables comming from socket and lamp -
than there is a connection on one wire with a fuse or something, on the other wire
there is a wedge (right word ?) - one wire disappears at this point somewhere beyond
the cap, the other one goes to the right cap - than in series with the other cap - than
goes to the strange thing behind the lamp, top of left end of generator.

For me its even unclear if the stuff not might operate with DC. The type of motor
used in the pump could even work with dc. At the beginning, only the pump is operated
with mains, than he plugs pump in the "output" of the gen.

What concerns the regulation -
You can control and steer things - in that case you adjust or tune something.
If your regulate something - there is a control loop with an actual value,
desired value and correcting value.
Capacitors might be part of a control loop setup - as integrator in an PI regulator
for example.
(....) I think we just use different words for the same.

Quick quiz:

I'm leaving in about 15 minutes to go over to my friend's workshop to look what he is using for wire to rewind.  We used a very thin wire and I'm pretty sure that he wrapped 550 times in each phase.  He wants to use a thicker wire, with the same amount of wraps for more power.  The question I have to this website, before I leave - what is your opinion on gauge of wire vs. clockwise, then counter clockwise and how many wraps per phase?  I don't know a lot about generators - I'm a pump and pulley man.  That's about it.  Please have an open mind and give me some info I can use to bring to my partner so  we can get this rewound and back up running as soon as possible.  The thinner gauge wire for some reason burned out.  That's as much as I know.

Whoever has an idea and have rewound a generator before, please give me your feedback before I leave, and it might help.  Don't forget that there is a lot more work that has been done to the generator and then rewound.  Maybe I shouldn't ask for help from any website but, I never know.
