It's not too far out left field, it's the central field, the very core of all - literally so.

So it's fine to post it as i already did on my thread in massive amounts.

Too bad most people get stuck on first step of so called orgone pyramids or basic merkabah

antennas and have to convince themselves they 'feel something'. This other spectrum i call

neutral i spoke of so so many times to which belong thoughts, vitality, gravity and antigravity....

is not so easily accessed in large amplitudes unless one knows exactly how. And it has to

be that way for sake of protection of the uninitiated.

As i said before, ALL is Phi, ALL is 9.

Okay- she is spinning.. First test is to see what the output wave looks like when she influences a coil.  Video shows her spinning and scope shots of the coil being induced..

I will be testing everything I can think of with her..  Definitely cool..

Totally agree.  Nice build too.

Hopefully you find some secrets hidden there none of us know about.

That's a very nice build Floodrod.  Instead of moving a magnet back and forth linearly why not make a shorter version of what you have and place it near the middle of your cylinder.  Then you could just spin it to move your cylinder instead of trying to start and stop a magnet which wastes a lot of energy.  It would require more magnets but it should allow higher speeds because you wouldn't have to deal with the effects of inertia of a reciprocating system.


Just my 2 cents idea.

Thank You Carroll.  Your idea is intriguing. Linear may not be the best idea, and I am not opposed to veering away from the original design.  Appreciate the suggestion.

First though I need to wind a coil around a 4" pipe and get this spiral rotor inside a big coil to see what happens..  I think theory suggest that spinning one polarity magnets throughout the inside of a coil that covers both magnetic domains-  is NOT supposed to induct.  But if it does...  hmmm..  Def need to know for sure.

Your suggestion has been added to the list of things to investigate :)

Today I wound a solenoid around a 4" pipe.  235 turns.  Spun the rotor inside and scoped it..  As predicted, induction is terrible to non-existent.  I didn't think it would work- but I had to check anyway...

Now on to the next step..  Getting the motor to run..  Linear motion might not be the best, but I will be starting there to continue mimicking the original source.  The original uses 2 moving stator magnets, 1 on each side..  I wondered why they used 2 steppers instead of 1.. They could have easily made a carriage and used 1 stepper to move the 2 magnets but they didnt.

Upon studying their videos, it appears they use 2 steppers because the 2 stator magnets run in opposite directions.  They both push in towards each other from opposite sides of the tube then out the other sides.  Hand testing and logic suggests both stator magnets are repelling the tube.  So this is how I need to design it.  Doah!!...

Edit-  Furthermore- they have 2 magnets offset on each side. Pic attached.

So I am pondering ways to build the same motion without the use of steppers.  Any ideas are appreciated!

First thought was a pair of these.

But they're not very fast.

A slotted gear might be another option but you wouldn't be able dynamically change the
stroke length.

Hey floodrod,

I wish I could build things half as fast as you do. Whew!

I wanted to toss this in here as food for thought. How about a lap wind for a 2 pole generator? This is from way back when...

Look out! A drive by posting!

Both ways seem possible.  Would be nice to have something that can be later looped to the rotation of the center shaft. Might have to use gears, even though I dislike gears..  PLA Plastic and friction do not mix well. 

I do have a collection of decent size steppers and a heavy duty controller.  Maybe 1 stepper top dead center that controls a crossbar to each magnet assembly.  Hard part will be the sliding slot needed where the magnet assemblies connect to the crossbar.   To remove the stepper and loop to the shaft will probably require gears again- but possible.

Thanks Cad...  I just ran and grabbed an old lap winding stator to see if it would fit over the rotor..  No luck, too small..  Even if it did, I think your image the wires run around the rotor, so not the same..  A very interesting proposal..  I hate winding coils, and that looks like a doozy..  But I would love to see what happens with it..

Ok well I think I am going to take this route.  See attached image..

this is not the actual design, but representing the idea..  Basically 2 linear rails driven by 2 cam arms 180 degrees apart from each other, powered from rotation of disks.   I can use a stepper and a belt to drive the center shaft between the disks.

All friction points can be bearings and I am pretty sure I can design this to work.  I can control exact positioning of the stepper and timing with an arduino and stepper driver. And I can make the stroke exact length by modifying the disk.

I had to order some more linear rail parts..  Stupid thing is going to need 4 rails and a bunch of linear bearing blocks..  So the next build updates will take some time..  I got a bunch of design and printing work to do as I wait for parts.. And these next 2 weeks are hell week at work.  But I will get this thing going.

Update..

Got the linear rails in the mail..  22 hours of printing the main carriages is complete..  Currently printing the stator magnet holders..

I also ordered stepper belts, pulleys, etc..  I will see if I can get it hand spinning with the linear system then move on to powering it once the next parts arrive..

Next update will hopefully be me verifying it spins with the linear rails and my hand motion.

Looks really nice so far.

I'm hopeful too your output shaft has tons of torque.  If it does, it would
sure lend credence to the MagMOV unit which you will be well on your
way to replicate.

Speaking of torque, did you do any calculations for the drum diameter?

Normally smaller diameter would allow you to get more RPMs, but I'm
not certain with this device.  It could be larger diameter translates directly
to more horsepower.

Thanks-

Nope- the only calculating I did was measure how big of a tube I had in the basement that would fit my magnets. LOL..

I printed out stator magnet holders but I can not get it spinning well by hand sliding.  I am unsure of exactly how they have their magnets arranged, how many stator magnets, polarities, etc.  It seems like attraction has more force than repulsion in this design. 

I couldn't get a glimpse of their stator magnets..  I am going to have to go through their channel again and see if I can get any clues I may have missed.

Here are some specifics I found where someone was trying to replicate..  But I guess that builder has given up.. Ghosted the thread on 2011 with no updates.
https://forum.dronebotworkshop.com/help-wanted/magmov-generator-need-sketch-program-help/

Generator Design Details:

1. The drum rotates by repulsion force between the linear tracking 2" x 1" x 1/2" large magnets and the smaller 8mm x 8mm magnets located on the drum which is referred to as the turbine.

2. All the Neo Magnets are N52 and the repulsion force at roughly 3" radius from center produces approximately 100 lbs x two at 180 degrees of separation. Roughly 200 pounds force on a 3" lever continuously down the length of the turbine.

3. The turbine turns at 300-400 RPM.  The RPM is increased via a spur gear with a ratio 1:6.  For each rotation of the turbine, 3 each GM alternators turn 6 RPMs.

4. The GM alternators produce roughly 70 amps each at a regulated 14.75 VDC.  So about 3000 Watts.

5. The 14.75 VDC is feed into a DC/AC inverter thus providing usable power.
