Mighty fine build you have going there Scorch.

hi guys,
there is my nasty coils motor project

hi, guys,
there is another my test:

Hey everybody; I finally got around to completing the wiring and commutator for the Q2 configuration and do have it up and running.

Preliminary testing is pretty interesting. Without any precision tuning of the motor, or alternator, timing it appears to be really close to being a self running system.
In this configuration; the first two capacitor banks are being charged and alternately providing a pulse DC output from 350 farad capacitors out to the 24 volt battery.
Section three of the capacitor bank is running the motor section.

With the main pulsed DC output connected to the battery which is also connected to section three of the capacitor bank and the pulsed motor, I am seeing very little, if any, voltage drop from the battery. But have only run this for a couple hours and I am already preparing to tear it back down in favor of the more advanced "Q3" configuration which eliminates all this annoying mechanical switching and adds a toroidal generator for a third output.

Which also has some very interesting capabilities including 'side stepping' the effects of Lenz's law and with the addition of other switching that uses just one relay and a reed switch instead of direct contacts, may actually produce even more power out.
For more details on this view these videos:

And, BTW, I did produce a short video documenting my project, actually operating, before I tear it down again.
See:

When I first started the video; the battery was at 25.0vdc and climbing towards 25.1.
After only 4 minutes of video it was already climbing towards 25.2 . . .

So I am really looking forward to whatever may be accomplished with the toroidal generator configuration.
The alternator rotor, and coils, are configured totally different for the Q3.
So it will require removal of the entire sine wave peak relay section, as well as the alternator rotor and stators, then build it all back up again.  .  .

That is all for now.

PS: I bought a new camera.

Just a note regarding reed switch timing of the Q2.
I am not a fan of this type of system due to wear of mechanical switches including reed switches.
As well as the differences between individual magnets that can have an effect even when a hall sensor is used.

Case in point-
Every since I completed the Q2 motor section, and got it running, I observed a pulsing irregularity.
I can hear it, I can feel it, and I can see it on the amp meter which throbs up and down versus a steady vibration of six firings per revolution.

So I connected an audible continuity tester to the reed switch and simply mapped the positions, on the timing disk with a pen, where the switch opens and closes.
At which point this became very clear there are different pulse widths for every magnet.
Four of the magnets are "average" but two are pretty short.
This is why the motor has a very uneven sound when it's running and I assume this also effects performance.

And the Q3 also uses the same type of timing while also adding a second reed switch.
I am now very motivated to attempt use of optical sensor(s) and a motor controller such as an Arduino. . .
Hope I can figure that out.

Somebody here had suggested I use an Arduino Leonardo for some other thing I was working on.
But I have no experience with such things and it will take some learning, on my part, including finding and building the optical sensor to work with the Arduino.

That is all for now.
