It looks like Torbay is updating his web site with a picture (maybe more to come?) of the New York meeting.

Here is a google translated web link: http://www.google.com/translate?u=http%3A%2F%2Fclub.telepolis.com%2FLICYTA%2FGALERIADEFOTOS.htm&langpair=es%7Cen&hl=en&ie=UTF8

Hello Everyone,

I found a video of Torbay;s working motor on Google Video!!! Check it out. I'm sold

http://video.google.com/videoplay?docid=6530358947613135242&q=transgenerador

Lets get building!!

God Bless,

Wow that's cool.

Hello All,

For those of you with CNC capabilities, I will be glad to provide CAD drawings to build a Torbay motor. I have one model that is based on specific sized magnets (check my previous posts) but I can always scale the model to different sized magnets. Since the biggest hitch at the moment seems to be finding a suitable magnet for the rotor. I did some digging around on the internet and found some small neo arc magnets used for small motors that should work. We could just arrange them in a half-arc on the rotor to approximate the radial rotor magnet sufficiently. Here is the link to the page; it is clearance item M5005 in the table: http://www.engconcepts.net/List_Of_Clearance_Magnets.asp.

If we choose to go with these magnets (unless someone can find some better ones). I will need to rescale the CAD drawings I made to fit the arc magnets. This would work out nicely since it would significantly reduce the overall size of the model (and price for the stator magnets) to make it easy for people with small CNC mills to make all the parts.

God Bless,
Jason O

Well i will be stuffed, I thought the video was never going to surface. How are all the projects that everyone started going?

Hmm, I wonder why the motor stops and starts so fast ?
Is there no inertia ?
Also the upper platecap seems to have pretty much free space (gap)
until the stator rollers hit the platecap ?

Hi Stefan,

I was asking myself the same question about the start/stop thing. I have three ideas about why it may be doing that.

1. It is geared to the little generator which probably requires a significant amount of torque to turn given the gear ratio.

2. There may be a lot of friction in the rotor axle and since it is spinning at a low RPM, it doesn't take long for it to stop.

3. Since it is powered by the magnetic fields, when the movable stator is taken away the rotor immediately hangs on the existing stator fields rather than coasting to a stop.

About the lifting stator arms, I did notice that sometimes they would pop up and fall right back down, but other times, they would stay up and be pushed down by the rotor cap. That shows to me that there is not a ton of interaction magnetically between the stator magnets themselves. Another thought is that the sheer weight of the stators might be helping them come back down too. One thing is for sure, the gaps between the magnets are much larger than I thought; there must be at least an inch gap between those stators, which, using ceramic magnets would be plenty of room to ease them back down without too much hassle.

God Bless,
Jason O

Is there a way to download that video? I want to analyze the frames but cannot handle that Google Video Format.

Thanks,
Eric.

Hi all

Eric, you can change the video format by simply changing the name from ?TRANSGENERADOR ICYTI 2.gvi? to ?TRANSGENERADOR ICYTI 2.avi? and then use VirtualDub to analyse it frame by frame.

Hi friends,
Another way to download the videos from google is to using vdownloader
http://www.enriquepuertas.com/wp-content/files/vdownloader.zip
You paste the url of video ( http://video.google.com/videoplay?docid=6530358947613135242&q=transgenerador ) and click download

It work with youtube videos as well.

I donÃ‚â€™t want to be a skeptic but after thinking about the video and watching it many times I found the video of the running motor a little puzzling in the fact that I have worked with small motors, drive lines, etc for some time and when the unit starts to turn it seems to almost start like there is a switch under the sliding magnet and the rotor is driven by a separate force. If I wasnÃ‚â€™t tied up with my Tesla experiments I would fire up the lathe and start on the new cad drawings posted here. Guess IÃ‚â€™ll just have to wait until I can build my own. I am in hopes that this is the real deal but as quoted:Ã‚Â Ã‚Â Ã‚Â

Or better yet build the base from plexiglass.

Hi Camster,

Yeah the video is definitely not skeptic proof. The thick base the stators are mounted on has always made me wonder if he could be hiding some things underneath to turn the rotor. But I don't believe this is the case after thoroughly studying the principle of operation, which seems to be sound in my mind. The other thing is that his earlier models were built on much flatter bases (like the one he made on the top of a CD). If it can be done that easily, we all can do it. Right now, I'm also trying to think of the best "duck tape & super glue" way of making a model so that those of us who don't have access to fancy machine tools to also build one. My guess is that most if not all the pieces could be made with a jig saw. I will also make scale templates of all the pieces so we can download them and cut directly from that in addition to the CAD models.

God Bless,
Jason O

P.S. Can anyone think of a simple way to make the ramp for the rotor cap? From looking at the videos, it looks like Torbay made his out of a strip of thin plywood.

c0mster · « **Reply #344 on:** July 21, 2006, 05:50:48 PM »

Just a thought: Perhaps using materials in model airplane construction could be used to make the rotor with the ramp. A ribbed circle built from balsa wood capped with balsa sheet to follow the contour of the rib design , like the construction of a wing on a model airplane, the balsa sheeting should be flexible enough to have a changing slope based on the rib design. Balsa wood can be made very strong with a coat of fiberglass resin and would make the rotor very strong. Not duck tape but close, all products can be purchased at hobby shops and Canadian Tire at least for the rotor.
