Hello,

Can anybody verfiy this, if that works, or is in mood to try to build it ?

Since i was there with some other engineers i think i can, this guy sadly does not know how to measure power, he did not know that flywheels are a mechanical capacitor and he thought just cause he has an appliance that states "3000 watt bench saw" that it will be automatically drawing 3000 watts.

Even showing him and explaining all this proving the duty cycle testing, he still this year went back on TV with the same measurement technique! He could do allot of damage to "FE" this way IMO.we certainly made a fool out of our selves, i left those videos up just to show the method he was doing, the wheel he had (gravity wheel) has some promise, but he never let us help him, and turned out to be rude to us(he doesn't like being told he is wrong), so we just let him be.

I do like the idea of pulsed flywheel personally, both in the frequency driven RV idea and the Jim Watson machine, how ever his system as is, will not give you any free power, you need energy to start that flywheel, and when its up and you load it, it will draw on the drive motor. There are two separate systems his gravity wheel (not working when we were there, work in progress) and his motor/flywheel /alternator

He claimed once that he got the motor alternator flywheel spinning, that he was able to plug in the motors input into the alternator and make it a cop of 1
He then claimed he could plug in a light bulb, he never showed us this and got angry when we asked to see it.

Go figure

Damn,
At last i thought, he had the Motor connected to the Alternator that it runs.
but just beeing stubborn isnt really a good argument.

The story i heard from him is that eventually this "self runner" destroyed his flywheel and he couldn't repair it, i have no idea what system he showed on TV recently.I am told he measured his power AGAIN by pluging in the same loads, ie, Bench saw etc, and he claimed to be drawing full power despite us showing him he wasn't previously by this method.So i am not afraid to say he is scamming people willfully based on this alone.

Hi Ash
I am currently working on a pulsed flywheel system. I am still in th early construction stages so I do not have much to show anyone yet.
I have studied Chas Campbells design as much as I could from Youtube anyway. But I cannot find much detail on The Jim Watson Machine, and never heard of the "driven RV idea"
Do you have links to those that would have more dteail?
Thanks
Bizzy

Hi Bizzy/ALL

Biz, a pulsed flywheel system is far more promising in my opinion, You will get a practical application out of it at the end of the day, the same with any one connecting a solar panel to the Bedini machine.

Now chas system would not operate as good as a pulsed flywheel scenario, plus drop the the "driven RV idea", as that was just an idea to make the prime mover more efficient, you can get nearly 96% efficiency in electric motors now . But if you have an RV around you would get close to a .9 PF with the right tuning i predict.

Please keep us up[dated in your project

Hi Ash
I will definitely keep everyone informed.This forum has been a tremendous help and I want to contribute. I have gleened a great deal of informtion. Not to mention people like Citfta who taught me a great deal about mosfets.

As I mentioned it is a pulsed fly wheel design similar to Watson's machine. The big differance is that the main axel is veritcal instead of horizontal. I got this idea during my windmill and alternator experiments a few years ago. It greatly reduces the friction and allows easier movement of the shaft. The other differance is that instead of an off the shelf alternator I am using a permanent magnet alternator, which also cuts down on friction. It is also a result of my old windmill experiments.

Currently I am working on the trigger/pulse part of the machine. Instead of using reed or hall effect switches I am using a pulsing alternator system to pulse the motor. It will either pulse the motor directly twice per revolution or it will allow a discharge from a continually charging battery twice per revolution. Until i get it set up and test it I wont know which will work best, although I am hoping the former will work.
Once I finish setting up the trigger arms and coils set up I will post some pictures so you can see what I am doing a poor job at explaining.

Hi Ash/or anyone lese for that matter
I have been reading Panacea-BOCAF On-Line University and came across the the part about Jim Watson's Machine particualrly where it says that

If you attempt to use a DC motor with a permanent magnet field in this machine, it won't work, because these motors ALWAYS produce reverse currents into the shorted turns of the rotor windings, and therefore, always produce DRAG when not connected to a power supply! You can see this behavior quite easily when you try to spin the shaft. A permanent magnet field DC motor will NOT free wheel when disconnected from power. They stop very quickly due to their internal short circuit on the rotor!

Do you know if a "wound field DC motor" would have the same problem or would a "wound field DC Motor" prevent the reverse currents and allow the flywheel to move freely?
Thanks

Or would a brushless dc motor be better at preventing reverse currents and llowing the flywheel to move freely?
Thanks again

Hi Bizzy

Glad to see you are still working on your learning endeavors. You are correct that a wound field motor does not have this problem. Once the power is removed from the motor there is very little current produced by the rotor moving past the field. The only current produced is caused by the residual magnetism of the field core and that is usually pretty small. There is some discussion as to whether a series field or a shunt field motor is better, but I don't think that part is really that critical. A automotive starter motor is one example of the kind of motor you are looking for. There are several places online that sell surplus motors and they usually have a pretty good description telling you if they are series, shunt or PM. Of course we are only talking about DC motors.

PS A brushless DC motor is another type of PM motor so it is not what you want.

Hi Carroll
Ok great, that is a tremendous help. I never thought about a starter motor being a wound field motor. We have some salvage yards around here that would be a perfect place to get one. Otherwise I was just going to get one at Grainger on my next payday.
I also thought the brushless and permanent magnet motor were the same but was not 100%.
Thanks

Hi Carroll
One more quick question... would there need to be any anthing done to the motor other than mounts to use it in a pulsed fly wheel system?
My first inclenation would be no, but I want to make sure i dont miss anything.
thanks again

Hi again Bizzy

You need to make sure the starter motor is in fact a wound field motor. Most automotive size usually are. However the small starter motors like for a riding mower are PM type motors. There is a long discussion on the Lockridge device thread about modifying the motor. I am talking about the thread that is a sticky near the top of this forum. I personally think you can do the same thing they are trying to do by quick pulsing a Mosfet driver circuit and using diodes for recovery but most of the people on that thread do not agree with me. So you will have to decide for yourself which way you want to go. By the way if you have not seen Peter Lindemans video about the Lockridge device you are asked to not post on that thread. You are of course free to look at anything posted there. There are a couple of more threads about the Lockridge device where you can post questions. I mention that device because it is very similar to the Watson machine in how it is supposed to work.

Hi Carroll
I am not too proud to say I know every thing nor too proud to ask for help so yes I will take you advise and look over everything. I hope this weekend to look over what the local salvage yard has as well as Grainger.i greatly appreciate your help
