Steele Braden Generator

You could cut circles out of acrylic and glue them in the holes in your rotors. Some hardware stores carry washers that big, but metal is probably not a good idea.

You're forcing me to get off my butt and get mine done, which is a good thing. Keep it up!!

Here's a video from Today, Monday March 10, 2014
Steele,a Generator 3 - YouTube

I'm picking up a few things at the hardware store today, including another sheet of acrylic. I don't know yet how many rotors I can fit on a shaft, but I will eventually have as many there as this project will hold. I have the front part of an old treadmill that will hold a four foot rotor, and it is sitting there waiting for something like this. I have used it for a lot of different things, but it is perfect for some large rotors and stators. No THAT would be a fun project!!!

I haven't been following this thread closely and so I may have this wrong.

I reckon that I see a NAB spool here. So, why not use a NAB adapter?

Hi Paul-R,

Hey thanks for that idea and link. That might work if I can find one thin enough. The effectiveness increases dramatically the closer the rotor and stator are to each other. So, the hub or adaptor cant get in the way to prevent close stacking of rotors and stators.

Hi Paul-R,

Hey thanks for that idea and link. That might work if I can find one thin enough.

You misunderstand the device:

Revox B77 tape recorder

If you look at the spool, it is held on the machine by the NAB adaptor. The spool is exactly 0.25 inch thick + the thickness of the front and back panels. Therefore, it is up to you to provide spacers to bring the thickness up to the thickness that the NAB adaptor expects.

You should be able to use spacers to get whatever thickness you want.

A good move would be to find a company that hires out stage lighting, sound recording equipment for concerts or rock gigs and go round and see them. They might give you a NAB adaptor that is scruffy or dented, and might be interested in what you are doing. (Tell them you are working towards self powered lanterns - that will please them).

Progress report

This is the last report for today.
Steele's Generator Info 3 - YouTube

I have to get to work on my Iron Pig's electrical system or my wife is going to be very disappointed in me, and that would not be good. I have lots left to do, but I am making progress. I'm at the point where all that is left to do is really put all the pieces I've assembled together. It will STILL take me a couple days, but I'll keep a working'.

I sat up late last night, as usual, watching tv. Only this time I was working on rotors and stators while I was doing it. Got all of the ones I have made done. I'll see how they fit today and that will tell me how many more rotors I can have on the setup. Will shoot some video of that a little later today.

hello
Attached a pdf with the templates I´ll wear to a local sign shop
to be laser cut out of aluminum & metacrylate sheets.

If anyone here needs it, I can scale them at any size requested. (also draw it in SWG for CAD)
and post here or send by email
That includes the shaft hole diam. in rotor, and also the four support rods holes at corners
cheers
Alvaro

Here is my first step in getting this thing assembled. Lots of work to do still, and no time today to work on it.

Building??

interdesign21,
Nice template. Are you building this then?

Dave

[interdesign21]

yes Dave
but I go slowly, saving a bit before I can order the parts.
very low budget here
I think that stator and rotor being made from a single alum. piece is an economy of resources.

I posted the template just in case someone may find it of use.

Teplate

When it comes time to step this up to the next level, I'm sure I can make some use of that template!!! For right now it will have to be aluminum tape on the acrylic disks. It gets me there the cheapest way I know how.

Glad to see you are building this, and taking it slow is no problem. Steele shared this with me what seems like a year ago, and I am finally getting around to building more than the basic setup. I too have been taking things slooooow!!

Hi voltage to low voltage idea

Hi Dave and All
I just now found time to look at this thread. Very interesting. I myself have been busy with other things demanding my attention.

I have an off the wall idea. This is something that I will try in the near future in my own idea of a looped motor/generator.

The first thing I will call your attention to is the C-Stack here:

The C-Stack by Cris Paltenghe

This is an original idea with 4 leads into a capacitor. Kind of like a capacitor version of basic transformer with its 4 leads. It too, can step up or step down voltage. So, it is ideal to capacitor couple the output of this generator and drop the voltage down somewhat.

The second thing is to take the output of the C-Stack and connect it in series with an inductor to the output. You want to try and match the resonant freq of this series circuit with freq output of the generator. A series resonant circuit by definition should reduce the voltage towards zero and the current rise to maximum as you approach within 5% of the resonant freq. The current will rise much more than a standard transformer ratio of volts to amps. It will be multiplied by the Q of the circuit. I estimate the Q of this might be in the neighborhood of 20, more or less. This huge gain is due to resonance.

For example, let's say you can attain speed of 2,000 rpm with a well made balanced rotor with 6 poles. To get freq in Hz, you would multiply by 6 and divide by 60 to get freq in Hz per second. The 6's cancel each other in the equation and you end up with freq of 200 Hz. Hopefully, this will result in components small enough to tune to 200 Hz? The higher the freq, the smaller the components at resonance.

The fact that this generator idea does not feedback load to the motor, means you should be able to draw off a good amount of power without it slowing the motor and losing resonance? In other words stable after tuning.

Hope this helps.

Dave et all
the attached template is for a 20x20 cm. stator. (actual scale 1:1)
As I mentioned, I may on request take it to whatever dimensions required. (of course for free )
This applies also to whatever modification or other additional pieces needed (eg. stand for a motor in line etc.)
Just post the idea or dimensions, and I´ll do it.
regards

Drawings of the Rotor.

Hi,
Got the Question why the rotors here are made to connect each other in the middle. All the other Machines i see have more Fields, where only the 180° Field is alternating connected to the one what is tapped.

Did someone try which Layout works better? Middle Parts conmnected to all fields? Or maybe only connect the 180° Fields with a bridge, only need a connection to them?

I am not about to build it, still have not really the right material, but its interesting. What i see from the handdriven Wheels, seems it works even better too when you could move the opposite (Stator) Fields too.

Joit,
All the petals on the rotor need to be connected to the central shaft. The shaft is in two pieces and those pieces are electrically isolated from each other. So you have one group of rotors that are aligned with the stators on one side, connected to one part of the shaft, while the rotors on the other (connected to the other part of the shaft) side are out of alignment with the petals on the stators. Also, all the petals on each of the two groups of stators are connected to each other. One group of stators is electronically isolated from the other, and the stators are electrically isolated from the rotors.

If you keep viewing the thread, you ail see the mechanics of it as I put mine together and maybe that will help.
