my initial testing

Hi everyone,

I have somewhat resolved my torque measurement issue involving my small digital scale (sample rate issues).

I am posting here my first (mostly) complete data:
The torque data comes from a small digital scale (-+ 0.2g)
The current comes form a shunt = 5.1 ohms. No correction was made for the power dissipated by the shunt, so there's some more to add to the output efficiency.

Load: 2 grams @ 2.33 inch torque arm
Voltage: Pulse 16VDC
Current: approx 75% of 0.196A Peak = 0.147Aavg
(see picture - classic R-L inductor charge curve)
Pulse Duty Cycle: approx 13%
Motor Speed: 1001RPM

Results:
Input Power: 0.30576 Watts
Output Horsepower: 0.000163022 H.P.
Output Equivalent: 0.124615 Watts

Efficiency: about 40% (without shunt power figured in)

I think this is all right but any input is appreciated.

Thanks,

Greg


Ch2 is the 5.1 ohm current shunt

congrats!

Got my Keppe motor running tonight. So far I've adjusted the rubber magnet ring up to 780rpm and still going. The little 9V has been running it for nearly an hour with no drop in voltage. I haven't done any testing yet for current draw or performance.

Is this a lot like the Bedini Window motor?

Congratulations Spearmaster. Now the fun starts ... trying to figure out if this motor is unique in any way compared to Bedini and Newman. It looks like a Cole/Bedini window motor but so do variations of Newman motors.

Oh well, happy experimenting,

Greg,

Your figures sound about right. When I worked for John Bedini's company, I built a small dynamometer and measured the efficiency of every motor in his shop. His Window Motor produced torque at about 45%, MAX. This is to be expected, due to the open magnetic loop, and massive leakage flux in the design. The best SG motor I measured could produce mechanical energy at about 28% efficiency. But the SG also recycled about 90% of its electricity, so the combined output of the SG was COP>1, but the window motor was not, because it had the bi-polar Cole switch, and no electrical recovery.

Nice model.

Thanks Peter,

I just visited the Keppe Motor Club and one of their engineers/technicians just posted instructions showing how to connect a neon tube across the reed switch to recover the field collapse. Well that's not spectacular at all but is a use of this energy ... but does not qualify as 'recycling' in my book.

I guess the thing that has always cast doubt about all of the energy 'recycling' arrangements (including Bedini's), IS the final analyses of these systems ... the indirectness.

When I talked to John on the phone years ago about my SG motor his comments were like "...well now do you see it...?", "...see what's happening...?, "...OK, there it is...". There what is? I left that incoherent conversation disappointed, and for me all interest in his work (pretty much) ended there.

Even the Keppe motor folks have a different version of the motor they're touting (Ver 3) than the one you see in my posts (Ver 1) but aren't releasing any details. But they now claim to be going 'open source' !

Oh well, it never ends. The best to you Peter. Thanks for responding,

Greg

first test

My Keppe motor started running at approx 780rpm with a freshly charged 250mAh 9V battery. It ran for a total of eleven hours and forty-five minutes before dropping to 650rpm. Any other tests I've done with the same battery on fan chargers and solid state chargers have run for forty-five minutes MAX before dying completely. The Keppe motor ran nearly twleve hours and was still running when I shut it down and still showed 8.8 volts. Not sure what the torque values mean and I haven't measured the current draw yet, but on the surface, the run time seems impressive.

Seems I've heard another story about a school girl motor than ran for a long time with a single 9volt. Hmmm.

Gonna try to send a picture of my Keppe motor. You may notice that I plagiarized gmeast's winder for this motor. Thanks gmeast .

Hi Spearmaster,

Ah yes! The winder is a very worthwhile effort. It probably didn't take you long to build it either but certainly saves time and makes a neater job. I see I was still lazier though by adding the counter. There's no way I could have kept track of 500 turns per stator half. At first I was going to do it by weight, but I sprung for the $32.00 counter instead.

Nice work.

Thanks for sharing,

Greg

Keppe Motor Club

Is anyone here registered on the Keppe Motor Club. It's a forum for motor replicators. I visited there this morning, read some posts and just went back to find the forum disappeared ... not the site, just the forum-all of the pictures, posts, replies, etc. The memberlist is up but I can't PM anyone.

The site is:

Foro gratis : Keppe Motor Club

Very strange indeed.

OK - now it's back up ..... sorry for the alarm,

Version 3.0

Has anyone been able to order the manual for the new Version 3.0 Keppe motor? I have checked on keppemotor.com, but they only have the Version 1.0 available for sale.

Thanks,

Hi Carl,

Well, the Keppe motor manual Ver. 3 costs $250.00 and they don't have the motor kit... just the $250.00 manual ... I was shocked at the price.

Version 3.0

Hi Greg,

What do you think you're going to do about that price? They offered to sell me the manual for $220.00 since I had already built and tested Version 1.0, but that's still a pretty large chunk. I think you can get the same deal if you write an email to [email protected] and tell them what you've done.

I'm not sure what their strategy is at this point, but it seems they feel the chances of getting manufacturing deals are pretty slim and they want to collect all the money they can up front. Unfortunately, I'm thinking this might end up being prohibitive.

What are your thoughts?

Hi Carl,

AAHHHHHHHHHHHHHHHHHHHHH!!! Those are my thoughts. Yes, I will try to negotiate some sort of discount too. I posted enough stuff on the Motor Club forum in support of the thing. I think they'll grant me some sort of discount. I did get a private e-mail from the STOP folks in New York thanking me for my input .... out of the blue ... imagine that? STOP has all of the patent rights to the motor technology as I understand it. They may be trying to get as much from the sale of the manuals to start some manufacturing ... just don't know.

How is your testing coming?

Best,

Greg

Hi Greg,

Actually, I just got back from a one month trip to my brothers place in South Carolina, which is where I built the Keppe motor. From there I went to Canton, NY - up on the Northern NY border by Canada to help Rick Friedrich with his Bedini Monopole presentation and workshop for the Bedini Fan motor at the Sustainable Energy Fair at Canton - SUNY, which was a great event BTW, then back home here to Louisiana a couple days ago to unpack all my stuff and start over again. As far as testing, for now I'm just going to believe your numbers and the numbers from the Admin at Keppemotor. The only testing I will do will be on a regular 110V fan that I have here to see if I can duplicate the Admin's findings.
One of my short-term goals is to put together a quick presentation for my EE brother, who seems to have a problem with the whole concept of Radiant Energy and high efficiency. Hopefully, the new Version 3 Keppemotor will fit the bill for this endeavor.

Here is a question; In your estimation, what are the differences and/or similarities between this Keppemotor and the Bedini Window motor? I haven't built a window motor yet, so I don't have that first hand info.

Thanks,
Carl
