Talking about phase...

[Bob Boyce]

Hi Bob,

Back in April I experienced the above. It appears to have a similar setup to what you have been doing. Could this be the case or was it just BEMF getting into the 'motor' coils ?

thanks,
   Bob

From some of the pictures of the SM device I looked at, it appears that SM used permanent magnets oriented to provide a fixed magnetic preload bias to his device. This would give a preset amount of angular distortion (twist) to his RMF. I do not know if he later went to adjustable fields in the interest of maintaining better control.

The magnetic field from an applied DC bias allows for an adjustable amount of angular distortion to form in the RMF. Polarity of applied DC determines the direction of angular distortion in reference to the desired direction of RMF spin, ie CW or CCW (depending on hemisphere). The strength of the DC bias field determines the extent of angular distortion in the RMF. Essentially, the kicks are the interacting energy, while the shape of the EM field can help to guide the overall operational characteristics. This is why so many device configurations are possible with this type of technology, some working better than others. Are you wanting a mild angular distortion to keep power down and minimize control issues, or do you want a wild angular distorsion to tap massive power at the trade-off of control stability and other possible issues? Having a RMF with angular distortion does not replace the requirement of providing interacting kick energy with sharp, clean pulses.

Again Bob, a wealth of information.  You have answered even unasked questions in your last post.  Thank you again.

A fellow builder and poster, working closely with me on our next build had suggested 3 phase, with the thought that it was probably what Tesla used for his famous "Egg of Columbus" demonstration.  And yes, you are correct, that at least in the early years, there was four poles on the SM TPU.  In his clues, as to the mechanics of the unit, he merely says, "segments".  But hearing the control problem you had with 3 phase, it sounds like you think it safer for us to perhaps start with two phase for our rotating field.

I have tried to get others to realize that it is the way to produce DC output.  The intermix of three frequencies, as facinating as they are, in producing alternating current, it is not overunity, but as SM says, "They are only a means to achieve an end."

With the potential danger that these devices "can" pose, when operating, how can we all work together to overcome these, and introduce such a working device to the world.  Or do you see that as "not possible".  Perhaps it could be scaled up to say "transmission station" size and used safer in that way.  I am sure you must have thought on this.

Warm regards,
Bruce

No, I am not recommending cutting back to 2 phases unless that is what you want to do. The amount of reliable interaction possible from kick reduces as you go to 2 phase energy patterns.

As to safety and use. Honestly, I don't think that the energy barons of this world would willingly stand by and allow this sort of technology to progress to widespread use without a fight. This is something that will have to be relegated to the grass roots efforts of basement inventors and tinkerers. Safety is relative to design. While it is entirely possible to design in limitations, there can be no absolute guarantee that something can not or will go wrong. All we can do it try to mitigate the issues. For example, if you design this to use a fixed power set of bias permanent magnets, and it runs great, but some yahoo decides to stick on bigger magnets without beefing up the control system... catch my drift? More is not always better, but some people do not see it that way.

Three phase, yes. The DC biasing is distributed around the core periphery. I have 2 different winding setups.

The one that incorporates DC bias into the secondary winding is one strictly for driving the hydroxy gas systems, and it is very tame in comparison. It lacks an intense angular field component, which makes it very mild-mannered in comparison. It is not so prone to runaway, but lacks in total power capacity. It is like a tropical storm at best. This is the one shared with the hydroxy gas crowd.

The one that has a seperate DC bias winding can introduce a much greater angular field, but it can be quite the beast to control. This one is like a hurricane that can turn into a tornado at a moments notice. This is one that can initiate intense lightning strikes and other nasty stuff if not kept on a VERY tight leash. Obviously, this one is not shared with the hydroxy gas crowd.

The controller that I designed and released into the public domain does not utilize phase control. Precision phase control is too dangerous for most of the type of hobbyists that usually want to build the hydroxy gas systems, so a milder form of controller was the answer. It uses pulse conditioning and safety interrupts prior to the power MOSFET devices. My method of precision phase control is via precision pulse duration and timing using software on a microcontroller. The outputs are conditioned and applied through safety interrupts to power MOSFETs via drivers.

The secondary wire lengths are not critical in and of themselves, as long as it is a full fill around the toroid. What is important is that the number of turns on the secondary, in combination with target DC bias, are used to determine optimum primary winding ratio. Core diameter determines the amount of power that can safely be handled without heating issues.

Pulse shapes vs effects... It's much more complex than just pulse shapes. But think about what you are asking. Do we really want that sort of information spelled out online, even if there were a mapping chart of frequencies/waveform patterns/effects? Just consider what could happen if certain people were to get all the information they could on negative uses of this or any other energy technology.

Hi Bob,

My partner and I had our eyes fixed on 3 phase, so thanks for that confirmation.  3 phase it will be.

I understand the new controller is proprietory, so I will not ask about that.     So let's talk mechanics for a moment.  Do you recommend 1 secondary and three primary, with the primary wound in trifilar fashion, wound perpindicular on the toroid, 360 deg.?

I thought I had run across this on your site.  I am trying to picture in 3D how you have wound your coils, or should I say, how you would recommend, for us to start and learn and study from.  The simplest design possible!     And I know it is difficult to express pictorially with words.  Let's call anything wound around the circumference of the coil, horizontal and anything wound perpindicular to that, perpindicular.  LOL

Warm regards,
Bruce

@Bob B.

The only general details left are direction (CCW or CW) - and safety measures.

I have freq sources - adjustable output.  With two signals I can do just about anything - drive logic circuits or drive four coils for four phase.

With the DC bias - I'll start with milliamps.

@btentzer
Hush the talk of "public" and "open" and replace with "private" and "cryptic".

I will take better photos during my next toroid winding session, that should help. I used to have a toroidal transformer photo posted in one of my project folders on the oupower.com site. I had to remove it because everyone was counting the primary turns and taking that winding count as absolute and literal. Even though I had put in that pictures description that the toroid shown had been wound for a particular application (a 290 VDC system), and would not work for any other voltage system. I tired of repeating this to people as well, so I finally just totally removed the photo.


@all

While on the subject of toroids, I contacted MicroMetals about core availability. As many have posted, they are still out of stock on the T650-52 core. I was told that the next production run of 90 units are due to be ready on 08/08/2007. Some have apparently ordered the -26 material cores as a replacement. I can only guess that they based this on material density and reference permeability, or maybe the lower price. However the -26 material has a higher temperature coefficient of permeability, and higher thermal conductivity. Quality is important.

I source my mil-spec wire from surplus outlets to save money, and tried doing that for cores as well. It worked ok when I was able to find the right cores, but I ended up wasting more money in the long run buying surplus cores to try.

hmm - iron core or air core - hmm - decisions...decisions
