The Robert Adams Pulse Motor Design Review

[toranarod]

Hi Rod, I hope not to abandon the project. We read every post of yours carefully. all good

Thank you
I am working on this every day. Not abandon at all. I am post mostly on the Romero Muller Rep theses days. just seem to be there now. not really intentional.
cheers

Hi Rod,

I'm about to order some magnet wire and I was wondering if I should get standard wire or would you recommend litz wire? I'm still going through the Muller post.

I ended up getting the Arduino Uno clone from Freetronics with the LCD screen (I like to be able to have direct feedback which can be an important debugging tool). I have pretty much learned the limitations of the programming language used... it's just a subset of C++.

if this is your first coil and pulse motor I am not sure what to recommend.
If you are going to replicate one of the projects in this post i would start with single strand wire and build a second coil with litz wire so you can compare them. Both would be a good idea.

Slick

Very slick and great workmanship!!

man that looks great. How is that piggyback coil working out for you? are you getting any usable voltage away from it? When I would short mine there was a greenish spark that would pop when I separated the wires. did you find the sweet spot where it will speed up under a shorted condition? rpm's, input voltage/current, and distance from coil face to magnet are critical. keep it up man. I know you are close. I am working on purchasing a house that is perfect for adding some of the devices built on the forum. Once thats all worked out I have a motor to build using the piggyback concept and a few other things ive been paying attention too. Im thinking a hybrid motor of toranarod, Mopozco, Minoly, RomeroUK, Konehead, Lidmotor, Slider, Jorge (skycollection), should do the trick.

I added an adjustable slide control to fine tune the coil.

great to have you join the crew.

Dude! Simply amazing!

I joined this forum just to reply to your post. I've been fascinated with the Adams motor for a number of years, but just haven't gotten around to exploring it. You have gotten me on track with your experiment and I am now looking at collecting the resources required to reproduce your experiments. Thus far, I have a number of different magnets and I'm expecting an Arduino soon (to learn how to program it, shouldn't take me long with a background in C/C++ programming and electronics). It will take me a couple of months to fully collect the basic materials to start working on it. I think the most difficult item will be the bearing and rotor, I have a few options for this.

Anyway, keep us posted and I'll do the same.

Good Job!!

Looks very innovative indeed!!

Hi Rod,

The 8 coil motor looks good. Have you continued its development?
Or did romeo side track you? lol

Alright,"using the Robert Adams cold current", can you explain this in simple terms for me? I have built a couple of Adams motor/generators... not too successfully, I should add. What are your cores, laminations?, 4:1 core to magnet ratio?

Ron

Old Romero did.

but I am back on track with all the helpful tips from Romero
this is what I am now working on this is my Own designee.
it a bit of every thing learned from all the experiments along the way.

I will fully explain this as I go. fingers crossed on this project.

It may be helpful to add a freewheel/flyback diode to each of your coils, i did this with my Adams motor/generator and it helps.

4 coils are 0.5 OHM and the other 4 are 0.9 OHM Each
when in circuit and controlled properly 4 coils wired together in series draw 25m amps or .025 of an amp on a 24 volt supply. using the Robert Adams cold current.

@toranarod
How many ohms /turns has one of your coils in your 8 coils setup?
