Thank you.

I already saw this and was hoping somebody would actually pencil in the SSR.
But, . . . . I suppose,. . .  I should just get off my lazy tail and build it.   

And, in reality, don't even need an SSR which, BTW, does have some speed limitations with these particular relays.
This could also be done with just another transistor such as the MJL21194.

I did manage to conceive how an optical timing disk should look.
I doubt if this is an original thought.
I probably saw something like it somewhere, sometime, in my past.
Looks like a shutter in a motion picture projector.

Two identical disks, cut from thin material, with tabs and not holes or slots.
And disk color probably doesn't matter much with an infrared sensor.  Uh.... except, maybe, clear. . .  acrylic is probably not a good choice. . .
For a six coil machine; can be adjusted from zero gap to a full sixty degrees wide gap.
And could actually be a pretty lightweight material including plain card stock.

But, still, need to get off my lazy tail and actually build it. . . .

What is the best performance anyone has so far. I mean in percentage, has anyone got OU yet? or maybe 95% Thank Jerry

I finally got off my lazy tail long enough to clean up the mess I made when attempting to uninstall the timing disk.
Quanta magnetics performed very well providing the new parts in a timely manor. Thank you quanta magnetics!

But these parts have been sitting on my bench waiting for me to get it done.
I did use a dremel sanding drum to create a 'notch' or relief in the hub in order to clear any new burs that may occur from the set screw in contact with the round shaft.
And that did work well. (see images) I just hope I don't run into a similar problem when I remove one of the rotors to be reconfigured for the Q3.

So it is nice to have this machine back up and running . . . so I can play with it and . . . tear it all back apart again. . . 

And it does appear to be running in a substantially more stable condition with the new timing disk and magnets.
The old disk did have a couple magnets that were not, quite, seated squarely in the holes, and sitting at a slight angle, which was causing a noticeable 'throbbing' or 'pulsing' in the motor that could be clearly seen on the amp meter.
Which is, now, almost completely gone. In the video; the meter movement is almost stationary now.

So now that I have it up and running again; I am going to start tearing it back down in favor of converting to a Q3. . .
But did produce another quick video before I begin tear-down.

I wanted to see how the alternator performs without any load or switching and I was impressed by producing over 200VAC out from just 25VDC in at around 200ma and under 500RPM.
And here is the video demonstration- http://youtu.be/iWMzBv3xCL4

I realize I have been pretty lazy and not really getting as much done as I could but, after all, this is still just an experiment for me to play with at this point.
Although the eventual goal is a system that may actually be practical and able to perform in a long term application similar to what has been demonstrated here-

That is all, for now, and I hope to accomplish more over the next few weeks.

Completed some more fabrication this weekend.
Made a jig for winding the toroidal stator and completed winding the coils.

Winding 250 feet of 16AWG magnet wire around a toroid core was a big pain in my tail.
Somebody should make an automatic machine to perform this task! . . .   

That is all for now.

Hello all; I tried assembling the toroidal generator bracket kit this weekend but was unable to complete due to some missing parts.

Also discovered that the larger through bolts and washers are so close to the smaller, corner, bolts that the washers are actually on top of each other. . .

Just some constructive criticism-
Not only should parts not interfere with each other; I think the corner bolts are pretty redundant.

With the two, large, through bolts and the correct spacers, shouldn't need the other, smaller, bolts, spacers, washers, and nuts right next to the large bolts. (Ten additional parts and expenses not really needed.)

Quanta magnetics has been pretty good providing solutions to problems and sending any parts I need so; I am just waiting for more parts to complete this bracket and get it mounted on the main assembly.

Looks like I may not need to convert the alternator rotors, and stators, for Q3 operation.

In the original Q3; the "alternator" section is just being as another pulse motor but this may not be necessary and, maybe, the alternator output could be useful for something else.
