A sincere gentleman sharing a magnet motor build .[NDA issues??]

[Dbowling]

TinselKoala,
I test my rotor in the following fashion. With magnets mounted, I have a small directional "fin" (It is angled so aerodynamic from one side, but catches air from the other side.) I mount onto the rotor against which I can blow compressed air. I speed the rotor up slowly to a specific rpm. For me that is 1800, since it is a number I use on a number of other kinds of tests. By adjusting the air pressure slowly, I can get the rotor DEAD ON at 1800 rpm. Then I turn the air off and time how long it takes to come to a complete stop. I do this several times so I can get an average. I call this my "run down time" for want of a better term. Your method with the string and weight might not work with stators and ramps and such in the way, so this is what I use since it can be used no matter what I mount around the outside of the rotor.


Now, as to what I have seen with this build. I tried two magnets on my rotor ONLY, to get my baseline. I balanced  the two magnets on the rotor with the two magnets on the stator as the instructions called for. I was happy to note that this did NOT impact the run down time which is what was claimed. This took a while. In fact, when I first tried it with round neo magnets, I was NOT able to get it to balance. There was always a sticky point. So I went to square ceramics. I was able to balance it with those. Then I tried it with square neos and was able to get it to balance with those. Others have been able to get it to balance with round neos, or at least that is what their videos show, but I have NOT, so that is what I am reporting. I will not try again with round neos as it was too frustrating. I added two ramps...one at each stator. With the two ramps mounted I saw an increase in speed as the magnets approached the ramps. However, the increase in rundown time was so slight I cannot statistically justify even calling it an increase...yet.  These were slightly curved ramps, but they did not have the recommended bend on one end. I had yet to make that modification. My next step WOULD have been to mount all the magnets on the rotor. I will be unable to do further testing for the time being as I have been evacuated from my home because of the Butte fire in California, and will probably lose my hose, as ten houses on my street  are now showing as in the burn area of the fire. So for now I'm stuck at a friends house watching movies all day. Hard life.


By the way, I was one of those that built a small modified UFO motor when he first came on the scene. I did indeed see that you could collect some of the generated power from the motor through the second set of brushes, but at low voltage the motor had NO torque, so further experimentation did not interest me. I can get as much OR MORE out of a motor by running it between potential differences, and it still has all the torque it is supposed to. So this is not a case of the blind leading the blind. I have seen what UFO has posted, but I concentrate on what the original discloser had to say, except in those cases where he affirms something someone else has said. And I keep good notes so I KNOW what he has said. I have seen too many threads go down the wrong road because someone stepped in to "contribute".

Good for you, I'm glad you are taking a scientific approach. Not many people do. Don't forget that the magnet fields may also affect your bearings; that's why I used completely non-metallic bearings in the example test I showed above. To "smooth out" random errors you should take data on at least ten or twenty rundown trials in each condition and get an average (mean) and standard deviation of the values.

I'm very sorry to hear about your house and the fire problem. Let's keep fingers crossed and hope that the outcome is not too bad for you and your neighbors.

Good luck for the house Dave, love your attitude.

Tinsel
You probably have before ...
however I forgot ?? [I have a vague recollection of it being a teaching Video of sorts]
can you explain this Vid ?

Vid was NOT AUTHORIZED For use and I removed it.
very sad to read about Mark E !!

thx

I'm in no mood to discuss trivia at the moment... I just read Mark Dansie's report about MarkE.

I can tell you these things:

The device was originally designed by Overconfident, who died of a brain tumor (malignant melanoma) several years ago.
The video was put up on YouTube to prove a point to Omnibus and was taken down after only being up for 27 minutes, as soon as Omnibus had seen it.
All copies of the video available on YT are unauthorized, plagiarized and many have been altered in various ways. Someone copied it without permission in the 27 minutes it was up and reposted it and it's all downhill from there.

The device is now lost, but you know where it may be (even if you don't realize it).

Teaching? Yes, undoubtedly. Did anyone learn anything from it? I certainly did.
"If what you think you are seeing appears to violate some physical law or principle, examine your assumptions...."

Out of respect for the memory of Overconfident, I really don't want to discuss it further. It was done to death back in the day, anyhow.
