HI Guys,

Finally got a chance to play today, gonna hunt around the shed and see what comes to mind.
Plan is water and High Voltage again, the idea just won't leave me...
Also in keeping with the "use your resources" approach-I will attempt to not be buying anything  for the build.
Of coarse if I get stuck before the deadline the wallet may come out, but I am sure I have enough junk laying around.
Video should be following later today with rough plans/details.

Good luck to everyone....may all your pulses spend their energy in the desired way!

Good times M3sca1 :) Look forward to see what you can create around the home.

Here is Ryan Abrams start to his pulse motor. He is using a commutator for pulsing a low power brushed DC motor. 2.7v @ ??? mA
 What he is doing from there is something different that is born from intuition and creativity. Hopefully he will be patient enough to do what his original idea is, which is electrostatic rather than magnetically induced. Talked with him and he said to put it on here for reference.

My intro video for this year.
I really like your flux re-route concept.  I think it holds great promise.

A slight twist to this approach is to use a high permeability flux re-route path that is disabled EXCEPT during the cogging (sticky) point.  It should take very minimal power to keep this path neutralized during the rest of the cycle.

Just a thought.

Hi Diadon,
Is this an official entry from Ryan Abrams?

you can expect a bunch of stuff from ryan....hes one of the most prolific builders i know  :)   
you guys are so busy....ill have to get an update together as well

If the stick point is 15° wide, the remaining cycle would be 330°. I would have to neutralize the flux (oppose it) in the reroute path for the most of the time. I don't think it would use a small amount of power to do this, but I can try this approach as well and measure it against the other ones.

Thanks!

hi, this is the first ever i join a forum,
i not a electrical base..
i just from building construction background...
so i planning to build a simple pulse motor with fan and light integrated...
making effort in modifying my previous R&D generator
cheers

As you guys assemble your pulse motors, I would recommend you do a little experimenting with coil shorting.  You have probably all heard about it before, but there is a trick you may have overlooked...

If you look at the typical sine wave your coils produce while generating, note the amplitude of these signals.  When you coil short at peak voltage or zero crossing of the amperage, you will likely see an impulse signal that has considerably higher amplitude.  The difference in amplitude between this signal and the normal signal is what you will want to focus on.  Why you might ask?

I have noticed if you harness only the excess energy from the spike and not the baseline output of the coil while generating, it does not lug down the device.  Free energy...?   Maybe, I'm not certain yet, but it would be well worth your effort to run a few experiments of your own while you have something on the bench to work with.

If you haven't experimented with coil shorting before, take a peek at my Universal Switch circuit for some ideas on how to construct the electronics.  Then all you will need is a trigger you can manually calibrate to the rotation of the device.  If you connect an isolation transformer to your generating coil and do the shorting there, the switching becomes much more simple, as you will only need to the two MOSFETs, two diodes and the MOSFET driver.  All the isolation components are no longer needed.  Be sure to find components with fairly high voltage ratings--you will be surprised by the voltages produced during coil shorting.  A three to four times increase over base voltages are common in my experimenting.

If one or several of you all are able to build a highly efficient base motor/generator device, it is quite possible the energy you can recover from coil shorting may make it possible to loop or at least increase efficiency near unity.  And I like to see Dr. Jones have to hand out more than one gold coin this year.   :thumbsup:

Good luck and good building all.

hi Everybody!!!
thanks for Matt Watts advices...
too bad that is i NOT good in complex electronic,
so i just use a simple way
by tonight should able to finished it off
so tomorrow can submit final entry

about the generator, i dun know how to justify whether is efficient enough or not
do we have a thread for that?
cause this is for the PMBO2016 thread...
don't really want to messed this beloved website

by the way this is my latest updated

hi guys
interesting about the rails with ball bearing
i did think that before to sent up ball bearing up to 400mm to spin my turbine (generator)
maybe this could help

anyway, i has sent the final entry
an andditional rotor has to add in...cause found out the problem with the NS rotor with reed switch and coil
kindly comment
and i will repost it
thanks

yeah and let me tell you that when using ed's PMH the coil shorting let's the rotor speed up while generating this huge amount of potential.
then shoot this into the ground to amplify it even more :)
it's really fun and i think it can be very usefull if done correctly!

on coil shorting only i could load caps from a (18 volts ac output on the unloaded coil) to over 350 volts by shorting.
wich got up even higher when pumped through the ground by using 2 ground rods.

Mine is a little behind schedule, but I got it running in the first approach.

I didn't measure the efficiency of the system yet.

Hope u guys enjoy!
