Hi Mags,

This setup LS shows tends to suggest what Ian hinted at if you recall my mentioning him in my posting ( http://www.overunity.com/13460/teslas-coil-for-electro-magnets/msg360671/#msg360671 )   i.e. the more coils are used (in a certain series/parallel) combination, the more flux can be brought into creating more and more torque while the input power stays about the same.  (Of course there must be a limit for the increase, for the rotor mass cannot be increased beyond the certain size or weight with increasing also the number rotor magnets.)

Also this setup as running from a capacitor would be ideal setup for testing coil shorting at the induced voltage peaks. I am not saying it surely gives extra output over the input but if is able to increase the run time, that would be a benefit too.

This is also valid for the Ossie motor :

well, my 'ossie' motor also runs on one cap  :)

runtime= 172 minutes - cap= 68000 uF, and then stops  :(

So it also would be interesting to see any improvement the coil shorting may cause on it.

Hmm, this would be great. I just wonder if there are any diodes or what coil windings used(difficult he says). Ive messed with caps as a source, with reed switching, and from a 1000uf, and the torque shown for the scale size, 'this needs to be the model' and developed upon. ;)

Hi folks, many of these things were brought up in this thread also.
http://www.energeticforum.com/renewable-energy/5911-garry-stanley-pulse-motor-8.html

My motor setup had only one rotor, one can only imagine if it had many, many rotors attached with the added coils wired to maintain the same overall resistance, to maintain the desired input wattage for a given shaft/rpm load.
So say with one rotor, it draws 25 watts for our given shaft load, (lets say lifting a weight) with the multiple added rotors, we could lift much more weight in the same time period, than we could with just the one rotor for the same input wattage.
All these air coils in combination with super magnets, will continue to give more and more shaft work for the same input.
This simple concept, i feel, is being obfuscated by some, for whatever reasons.
This concept could be, as in a car, broken up into separate motors to power each wheel or one giant carnival type motor wheel could be built that used 100 watts to power huge shaft loads for towns.
peace love light

 :D Hi LS :D ,
I must say that it's an amazing piece of engineering. Plus the effort to make it thru a 3D printable spec so everyone can easily reproduce and test it's spectacular.

Thank you so much for sharing.

LS, have you done any power consumption measurement? Have you tried to put it on scope?

Someone talked about diodes in this thread. In the case someone in this thread would like to experiment LS design with diodes, I would recommend germanium diodes.

 :D Thank you for sharing  :D

@LaserSaber (posted on LS web site as well)

I think if you can find a germanium diode and point it towards the capacitor, it may help in increasing the motive force of the wheel. Since the capacitor has no diode and the motor contact is done via the reed switch, this indicates that the coils-cap-reed are probably all in series. Caps discharge on connection and inductors (coils) discharge on disconnection. I think the energy being sloshed around is much higher then what you see, (shown by the torque) but because the capacitor does not have a diode, it is simultaneously in continuous charge and discharge state. With a diode pointing to the capacitor, it may cut half a cycle to charge but that half cycle will still be consumed by the coils and the other half cycle that does charge the cap may be of higher final voltage that could not be captured without a diode because the whole system is running in an rms mode where everything is levelled off to the least consuming state, which is also the least producing state.

Not 100% sure but I am sure it would have to be a germanium diode (only .2 volts loss) and the effect will surely be interesting to learn from. Even trying a diode placed in series between the half way point of the series coils may provide another effect of interest. Or, just tapping the diode at the coil half way point and point to the capacitor.

Cascading coils does not necessarily rely on the precise replication of the build but the overall set-up can be duplicated in many ways. Again I tried to explain this to Romero, telling to put his top and bottom coils in two series. Anyone with a Romero wheel can try that right away.

So many ways to learn about effects when the base process is stable as you show now.

PS: But........first of all........ enjoy your vacation!!!!!!!

PS2: @schuler

Yes is should be germanium but even with germanium diodes, they are not all the same reaction so the best thing to do is make a diode carousel and test many models as the wheel is turning. One diode may outperform the others by 2 or more times greater.

Hi forest,

Yes.  its rotor has torque.  I would like to understand what you do not understand...    :D 8)

I assume the long run time would decrease gradually as you would try to utilize its torque.  The mass of the rotor together with the weight of the 6 magnets is the "useful" load at the moment as shown in the video (and of course the air drag of the rotor).

Hi LaserSaber,

Excellent work.

Here is a way to improve torque, angle the magnets and coils so that the force is pushing over the center line of the rotor. In this picture it is angled 30 degrees from center the coils are also angled the same degrees just translated outwards from the center of each magnet. You can change the angle to whatever you want. The goal is just to get the force to push over the center instead of at the center.

Looking forward to your next design.

Edit: It's actually 30 degrees for each magnet in this setup. 360/12.

"The mass of the rotor together with the weight of the 6 magnets is the "useful" load at the moment as shown in the video (and of course the air drag of the rotor)."

And the drag of the straw.  ;)   

It seems as though what ever rpm it is set to run, the caps voltage adjusts accordingly.  If the straw drag were another generator that slowly charged a cap for periodic pulse discharge, maybe it could be made to increase in rpms on its own. I dunno. Im patiently waiting for directions for the build. Hopefully it comes soon. Im getting impatient. lol ;)    Knowing what LS has shown in the past, this one has my attn more than ever.

Dreamthinkbuild,

I have used a coil at an angle like that with a motor that was pushing the mags and it did produce more rpms. The mags were straight though. So the coil was pushing on the magnets field in the direction of rotor motion, instead of pushing/squashing it against the rotor.

But here we have 6 mags and 12 coils. Mags are all the same polarity and the coils are alternating polarity. So the coils, 2 of them can act on a rotor mag at the same time, pulling and pushing=more torque. Im not sure it would be good to angle the 2 coils toward each other, but anything is possible. I would only try after a working model is made and then experiment beyond. ;)

It almost seems like if the air drag was eliminated, it could increase in RPM by itself.
He needs to do two tests.

1: Spin it up to about 1500 RPM with no electronics and time the spin down.

2: Make sure the capacitor is dead. Spin it up to the same RPM and then connect the electronics, then time the spin down.


Make sure the capacitor is dead and to connect the electronics after the initial RPM is reached so that all imparted energy is the same in both tests.

Yes, that would be a great informative and simple test to run.
Nice work, good posts.
 
Thanks
Mike

Actually that would be easier. ;)

That is the beauty with 3D printing you can keep the original design and just swap out a new rotor or stator with a different angle for testing. At this scale it probably take less than 20 minutes to print the rotor. Keep everything modular like the coils so they can be snapped in and out of the different designs since they take the longest to make. Use friction hold on the magnets so they can be taken out and re-used. Lots of options for experimenting.

Hi LaserSaber,

Just a quick question. What is the infill percent for the rotor?

I tried to replicate LaserSaber`s first 3D-printed motor as shown in his video http://www.youtube.com/watch?v=Esphle_MsXI

My version was done by hand (super glue), therefore it is not precisely built.

The axle is a needle which sits in a little hole (in a bolt in the centre of the base) and is held upright by a magnet above its upper end (also like in LaserSaber`s motor). The needle top does not touch the magnet, the distance to the magnet is about 2 mm.

When I blow air at the rotor its starts to turn and turns for about a minute (the needle bearing is that good).

I will use one coil as a trigger coil, see the scope shots over one coil when a magnet passes rather slowly. May be the trigger coil will need a special shape and will have to be placed at a specific location (as a seventh coil). We will see, if all fails I use a Reed switch like LaserSaber.

I will try with the transistor 2SK170 or ALD110800 or ALD110900, because they switch with very low Voltage at the base (zero offset).

The coils are from six 12 V relays, about 90 Ohm DC resistance. The diameter of the base is about 120 mm.

Greetings, Conrad

Untill we know more, its hard to say what rpm it can run at. It seems the cap voltage changes with rpms, where maybe 1500 rpms might breach the 16vdc of the cap rating.

What it seems like is he can just spin it up from a stop and 0v, and it will be at whatever voltage associates with the rpm. When he did the speed up with the air from the straw, the voltage went up and rested basically at that rpm level.

Im very eager to see details. :o :o :o ;D   From what I see and think about what I see, this is what everyone should concentrate on once revealed. ;)

3D printing or not, you did a nice job.  ;)

I think the 12 coils, with less space between them allows for a push and pull between coils, as he stated alternating polarity of the coils.

What relays did you get those coils from?  I like those.  ;)
