I spent the best part of last week studying your resources from google drive folder. It's a lot to take in, but I thought it necessary to be on the same page as you when you're explaining the new upgraded Aspden motor. I ordered the Ultra Fast Pulse Motor Driver Board sir, as it would be the height of foolishness to follow along with this project and be missing vital parts of the system. Your transparency is reassuring. Keep up the great work. Thank you for your help thus far Nick.

[@Waveguide]

Great, thanks for the order! I will try to get it over to you as soon as I can.

[@hoofheartedicemelted296]

@@Waveguide I'm so greatful for having stumbled across your work sir. Previously, I was a bit overwhelmed by the amount of information available that had to be sifted through and understood. So far you have managed to do the most efficient job of simplifying complexity and breaking it into bitesize info so ordinary people like me can understand what you know too and maybe get the benefit of this tech. Anyway I'm ranting sir. The next thing is to locate Aspden's patent to get an idea of the dimensions of the motor structure to feed into my 3D printer and then onto the battery swapping elements. Thank you Nick for decoding Babcock's breadcrumbs. So thanks to you I don't feel overwhelmed now. Best of luck sir.

Thanks for sharing Keep up the good work

[@kbeefer2]

It is good to see you back on pulse motors. Thanks for the links to the ESTC 2022 videos. I also watched them and got a ton of inspiration out of them. For example, I had never heard of silicon carbide diodes before... Perhaps I revisit my shelved Adams motor to try to suck the flyback out of it and study a bit before going into some of Babcock's ideas.

[@Waveguide]

Yeah those diodes are great! Can handle enormous voltages, are incredibly fast, and result is nearly no switching losses.

Hey Nick! Glad to see your new video and to know that you keep working in this field. When I watch your video, it seems to me that you do everything even too well. I hope everything works out for you. Good luck!

[@Waveguide]

Great to hear from you, Alexander! Yeah I'm putting everything I learned over the years into this thing, and try to improve every single part of the machine. If this one doesn't deliver the promised results, I'm out of ideas haha 😂

[@alexanderkrupnov4999]

@@Waveguide, I think by the time you get it right, like Adams said, the machine itself will tell you what's wrong. You will see for yourself what you need to change and go one more (or maybe more than one) level higher. So don't worry about ideas! I am currently working on this patent as well. Actually, so far I have only tested a disk with 7 magnets and just one pair of coils. It was interesting to check how the principle works "while one coil (of this pair) repels, the other attracts". It's very interesting!

[@Waveguide]

@@alexanderkrupnov4999 Glad to hear you're still experimenting as well! Would love to see your new setup 🙂

@@Waveguide, OK! I'll email you later and maybe put in some pictures. In the meantime, I'm reading your blog post, because I'm not very good at listening to English and I don't understand everything in your video.

[@sinergicus]

Thank you for your work and all the informations you gave us on your you tube chanel and blog.... I am curious if that 3d printed plasic rotor will not explode under high sppeed and centrifugal forces ... Maybe would be a good ideea to wrap it in some electrical tape to be more safe when rotating at high speed...

[@Waveguide]

Good point! The rotor is only going at ~700 RPM now, and I calculated the force and compared it with the tensile strength of the PLA and it can handle much higher speeds, so I'm not too worried. My smaller motors went up to 4000 RPM, and the plastic never budged, but the magnets did fly out twice due to poor glue strength, that's why the only thing I'll ever use now is epoxy, which becomes rock-solid + I always wear protective glasses. Ideally I would place a transparent screen in between me and the motor as well, but heck, you got to live a little as well ;-)

[@Gacha.Cupcake]

Great job. Any update? Thanks

Hi! I wonder if you know where to find these big value photo flash electrolytic capacitors that seem to be the preferred capacitors for the SG according to the Bedini SG handbook 2?

[@Waveguide]

Mouser.com or AliExpress.com should have them

[@hoofheartedicemelted296]

I've watched this about 8-9 times now. The curiosity is killing me sir. What is that small version of the rotor structure in the background? Is there an application for several small versions?

[@Waveguide]

My plan was to build a small version first to test out the idea for less $$, but then I decided it would be almost the same amount of work to build a large version, so I did that instead :-) Never actually used the small one.

[@hoofheartedicemelted296]

@@Waveguide Bedini to Babcock "Never build anything bigger than a bench-top model". Yes, I understand. Thank you sir.

[@hoofheartedicemelted296]

If you wanted to invert the phase of the current in the ouput ( charge battery ) would you use an op-amp? And what terminals would I connect the op-amp to? The negative of the output or the positive? Thanks Mr Kraakman.

[@Waveguide]

Don't have to invert, just make sure charge battery polarity is correct. While the flyback shows up as a negative spike, it really just depends on where you measure, since if you measure from the end of the coil to the beginning, the phase seems magically inverted. The coil becomes the source instead of the load when the field collapses.

I purchased your vedeo on that thank you

[@claudeposternak5006]

Here's what I want to see from a pulse motor, and eventually build myself: -The stator actually rotating freely in the opposite direction to the rotor, meaning that you will have no mechanical torque as an output but all the rotation will go back into generating more RPM thus more pulses. -Adding weight to the rotor for increased momentum, so that when we generate from the coils the increased weight will power through the resistance better and thus give more power. -Isolating the device within a vacuum to reduce drag.

[@Waveguide]

Hi Claude, thanks for sharing your ideas! Here are my thoughts on them; - "Stator" is derived from "static", so non-moving 🙂How do you plan to make the stators move? You'd need some sort of motor for that too, right? - Creating a flywheel effect as you describe works best by adding weight on the periphery, which is where the magnets are, so will be tricky to add more there. Take into account though that additional weight requires additional power to keep it spinning. A flywheel is like a mechanical battery, so in the end you might get more power out, but will have to put more power in as well, so no net gain. - Operating in a vacuum would indeed reduce drag significantly, but the energy required to set up the vacuum should be taken into account in the energy in/out determination.

[@claudeposternak5006]

@@Waveguide Agreed, this is what a traditional stator would do, however in my concept the outer ring of coils, let's call it, is spinning the opposing way to the rotor, provided by the same force that pushes a rotor against a traditional stator. You would probably have to experiment with the amount of magnets/coils to get it right and have a way of providing electricity to a spinning "stator". Agreed, tricky but not impossible. The whole thing is tricky, says Bedini. The weight impacts the speed up process more than the top speed, and the gains you'd notice from the added weight should total more than the cost to keep it there. Sure, but once the vacuum is established you have a greater amount of power for a longer period than the initial vacuum process.

[@hoofheartedicemelted296]

Mr Kraakman if I may. What is the purpose of the 2 capacitors in the lower part of the schematic? ( C7, C3 ). Thank you sir.

[@Waveguide]

The larger C7 and C6 caps are to ensure we can deliver enough current in the shortest amount of time for the sharpest possible rise time of the gate pulse. C3 is a filter cap to ensure a cleaner signal with less high frequency noise in it.

[@hoofheartedicemelted296]

@@Waveguide Thank you Mr Kraakman. I apologize for torturing you with questions which you have answered graciously I might add. It is one thing to simply replicate your method but if anything goes wrong I will have greater success repairing, modifying or adjusting components if I know their purpose and how they should operate. This should be a fantastic learning tool for me. Thanks a lot Mr. kraakman for all your help.

[@hoofheartedicemelted296]

Mr Kraakman sir. In the dc to dc converter does the op amp come pre-programmed or did you have to configure it sir?

[@Waveguide]

The one I use is pre-programmed for 12V output.

Why you are not using discoidal shape rotors to have acces on both side of magnets without design complications?

[@Waveguide]

Because I have no clue what a "discoidal shape rotor" looks like haha! Also, this design is inspired by a rotor Robert Adams designed later in his career.

So the 48v goes to the coils and also goes to the voltage regulator at the same time?

[@Waveguide]

In this version of the board, yes. The 48V is what is pulsed through the coils, but also goes to a buck coverter that steps it down to 12V to power the gate driver, and also goes to a 5V regulator used to power the interrupter.

Why are you not using the original robert Smith mechanical switch timer....using commutator? What are the cons of using a mechanical switch timer?

[@Waveguide]

The mechanical switch is a little harder to build and control vs using a MOSFET, but Adams recommended people start with the physical commutator, since you don't lose any energy to power the switching circuitry. However, FETs have become much more efficient since his time.
