Regarding The Ed Gray Motor

I read somewhere that the coils all fired at once. If that is true I find it hard to believe that any power could be recovered from this particular motor. In that it has 3 stator coils. With this in mind, All the magnets on the rotor would have to fire producing the same magnetic field either north or south, and the stator magnets would have to also produce the same field as the rotor, to get the needed magnetic repulsion to continue the rotation. This is why a start motor was needed to get the larger one to start its rotation. It could not self start with this wiring scheme, but once it was spinning it would sustain its own rotation and produce a large HP.
Now if only one of the three magnets fires at firing alignment then, the other two non firing contacts could be aligned to allow power recovery. this would happen 3 times per rotation, but the motor would not produce the power it would if they all fired at once.

Its maybe the 2nd Impuls, what gives the Power back.
The first turns the Rotor, and then the input is locked, and you can get out the Power.

I read today something about only Pulsed DC is natural, all other Kind of Current is unnatural.
I think all time about a Setup, where the positive Amplitude from AC should drive the Rotor, but i cant stop, to play around with Coils.

Here is a file that I constructed, to help see how the commutator works. Notice the two different wiper configurations? The single wiper configuration is this one http://keelynet.com/evgray/128.jpg .And the 3 wiper configuration as seen here http://keelynet.com/evgray/125.jpg . These are two different motor assemblies, and are not both part of the same motor.

I think you may be a little off as to its operation guys. Then again, no one can really be certain. This might interest you, if you havent seen it already. YouTube - The History of the EV Gray Motor - Lecture

Yes I allready have that video.

I think you may be a little off as to its operation guys. Then again, no one can really be certain.

That sounds like a conflicting opinion. I'm trying to figure out the commutator by using photos of the actual device. Along with the patent drawings and descriptions.I have compiled a mountain of files and articles on the motors of EV Gray. I have a pretty good knowledge of the workings of a DC Motor and commutating power to the coil or coils. Dissecting the photos, you can learn a lot, Especially when it is a prepared photo series. In one file I read where the "found" motors commutator showed allmost no signs of wear.
By looking at this photo http://keelynet.com/evgray/128.jpg I can see signs of wear, but more importantly, I know this motor had to run to produce this wear. Whether it preformed as claimed I don't know.

It is conflicting, because I havent personally seen or built the device in question. The only information I can add is hearsay, or educated guesses based upon pictures and info. The video I linked to above is from a gent who personally got his hands on some of the motors, inspected them and studied them fairly vigorously from what I hear. I am inclined to listen to what he has to say, since he has had hands on experience with them. If I recall correctly Norman said there were different phases of firing, so all firing at once doesnt sound correct. Then again the stator has 3 poles and the rotor has three poles, all seemingly @ 120 degrees or thereabouts. Also, there are a few different motors, and what you say about one may be correct, but be incorrect to a later version.

From memory Norman said something about the rotor and stator coils were linked in series when they fired, I have to watch the video again I think. I also think the electromagnets that fire on the stator and rotor arent part of the recovery/recharging system in the way most people think.

From what I understand the Rotor/stator is the easy part of this build. Its the power supply/method that is the hard part.

Yes the Rotor and Stator setup is the easy part. Its the distributor style commutator That I'm trying to figure out.

Hello,

You may find some more information here also:

there are a few pages on Ed Gray, but also many other Special Electromagnetic Motors

good luck !
it's possible !

Help with caps for gray tube

Hi

Can any one help me? I am hoping to build a gray tube and in the diagrams at http://radiant.100free.com/zpe_gray_sparktube.html , the caps are 5KVA and 12UF - where can I get these from? I have looked at the RS site and cannot find those ratings. I also notice on the same diagram that the cap on the HV tube input is polizarised, does that mean all the caps in the circuit should be also? Any help will be much appricated.

Many thans

John

caps and size

Hi John,

I believe the caps should be polarized and you also don't need one that big. 3-4kv and 2uf is the lower size that works.

about sparking tube

Hi,

happy to read again somebody wanting to work on Gray's tube

you might use a Marx Generator as experimenters get success with it, and it uses small HV caps, what is cheaper and easier to find !

"400pF 30KV ones are $12.50 each. The 6.5KV 1500pF are 99 cents each"
from: http://radiant.100free.com/zpe_gray_mckay2.html

marx generators:

http://radiant.100free.com/zpe_marx_generator.html

you should try also with circuits found in the water exploding experiments, because it's even easier and cheaper to get high RF sparks, like you can see in Jetijs videos:
SCR triggered CDI system with water spark mod YouTube - SCR triggered CDI system with water spark mod

good luck,
and don't forget to report any results, good or bad,

About his motor I have not seen anything detailed but I have read his patents from -86 and -87.

Basically as I understand it he sends a magnetic pulse(south pole pulse ionizes positively, north pole negative) which ionizes the coil and repels the south side of the rotor magnets. During the next moment(when breaking off the HV pulse train) the back EMF from this coil is sent to the charge battery and then the next phase is pulsing the magnet again at 120 deg angle. Hence his results.

We have to think magnetic pulse, the electric phenomenon will come after the magnetic pulse(cold current, radiant charge etc), but that is only my guess at this moment. Remember a strike of lightning can magnetize a cliff permanently!

Aaron, Stephenfreter and Gauss

Many thanks to you all for your inputs. Aaron thanks for pointing out a lower cap will do, I am still having difficulty sourcing a cap of the correct type, so may try making my own caps with foil. Stephenfreter thanks for the steer towards the Marx generator - very impressive and an idea to keep in mind. Gauss, thanks for your comments, I am intending to initially use a single coil to prove the concept.

Will post back when I have something to show.
