Muller Dynamo

Hey Scorch

Do you have the motor running yet?  Just wondering if you are in the same range of rpm as Romero had with your build.

Nice work. ;]  Eagerly waiting for running vids and results. ;]

Again, love the horizontal axis. Both sides are always available for making changes and adjustments. No flipping it over, well you know. ;]

I did have it running including my original build which used the stargate motor as the primary mover.
As well as this build with air cores and mechanical switching.

The stator plates on this build have 1/4" holes which are a little to big for my ferrite cores.
SO; I am back to starting over again because I am being a perfectionist and want holes that are a nice, tight, fit for my cores.
And need to throw together another rotor because this one is slightly wobbly even with the dual, aluminum, hub mount. . .
And, of course, other projects with higher priorities so not sure when I will have this built and running again.
I still have the coils, and all the hardware, and I think I even have everything I need to build the hall senor circuits; but it's going to be awhile until I get this going again.

BTW: I don't know what range of RPM Romero had.
Just know that it appeared to not be very fast in the video.

When I was running it, with mechanical switching, I was getting about 800 rpm but was having problems with the wafer switch 'bouncing' on the 8 lobe cam.
Wish I had a had a switch similar to regular ignition points, with large spring and proper cam follower, that is normally open instead of normally closed.
BUT also still had a problem with the cam not being perfectly centered on the shaft. The hole in the middle is just, very slightly, off center resulting in uneven switching.
I just don't have the facilities to do it right. Need a lathe or machine shop to perfect it.

And, in my case, more complicated (electronic controls) is turning out to be simpler.

But I am still thinking in terms of automotive ignition controls such as these. (see images of two different types of systems)
Which are readily available, cheap, already built, don't require physical contact, and are designed to be very precision switching; versus a hall sensor next to spinning magnets of undetermined dimensions and strength.
And some even have 'timing advance' and 'dwell' which might help to compensate for different RPM and generator loads and maintain the resonance we seek.

Hi ,
regards to all
I'm a Time studied motor / generator by RomeroUK, my results have been getting better and better but once I'd got excellent results with the gap of the magnet coil and the golden spot disapared, .This days i  again played withI this beautiful motor/ generators.Sorry in my  English (google traslator).I am from Croatia

Here is a good book for you to read about dynomo's. Maybe it will provide you with some insite.

  The Muller dyno does not seam as finished as one might like.So you can always design one of your own with as much gathered info as you can find. Im kind of partial to finding why or how Tesla's improvements worked. If the breaking effect can not be turned into an additive motive source then chances are it will never get to cop1 much less anything above that.

 The sears patent mentioned in the book gives refference to the spiral plate improvement as a squeezing of the electrons to outer ring as they become narrow at the ends. That doesnt really work that way in my mind. Considering static surface charges on a capacitor plate would then act in the same way which would have been disovered by now if that was true. So that notion is wrong. It could follow along the line of thought to act like a pancake coil though or to take a small radious and stretch it so it acts like a much larger diameter disk.
  There is also mention of how back in the early days someone glued the magnets to a disk and spun the entire outfit and it still worked. That really screwed with their theories.
