Maybe possible idea for duplicating effect of Holcomb and others

Hi UFO,
Your schematics are looking great!  I don't see your ideas in any way detracting from the purpose of this thread.  Your suggestions and helpful drawings are very welcome here.  I, like most people have only so much time and energy to devote to any project.  So with several of us working together we stand a much better chance of reaching our goals.
What program are you using to create the beautiful schematic drawings?  I switched to Linux about a year ago and still haven't found a good schematic program.  I spent a good part of the day yesterday trying different programs but before I finished a good schematic you had already posted yours which I liked much better than what I had.  Thanks again for your input.

Thanks Citfta, I feel better working in a Team of Positive People...as long as we work for the same goal.
I see a lot of possibilities with this so simple circuit, which I think We could modify to work on a Modular basis to be able to add more FETs and more Coils to make it more robust and less "aggressive" as too high gauge wire, like Alternators have.
We basically need somewhere around 2-3 Amps and higher voltage to generate a great exciting inducing field of higher resolution.
Now, the program I use is TurboCad (IMSI), I am running it on Windows 10/ 64...and it cost me like $260.00 USD, the Deluxe version 2021.
I have no idea if they make a Linux version...

I also have AutoCad (Autodesk)...but it is far more complex Interface than TurboCad for this simple schematics.

I had my electronic components ordered...and also have to build a rig for one of my Alternators...I got the brush assembly out, and modify it, to use it on my Rotary Switch...but no problems...I will do all that next week.

We will make this happen!!, I feel very positive about this Alternator setup that you originally came up with...basically for the simplicity in every way you look at it...the Alternator Stator winding simple ways to make it, plus this Circuit based on just a few components!!
You know the Complexity to wind a BLDC Stator...one CW, other CCW, alternated irregularly, then second circuit...then third...it is a nightmare...so, knowing the simple Alternator winding works great...I believe it is a very huge advantage.

Beck to Holcomb system. I received one of the rotors that I ordered. the small one.
As soon I have time I will start to work on that. The stator is a 1 HP motor with four poles that will be driven by a small VFD that can speed up to 200 Hertz. It has 4.5 Amps as the limit.
The first attempt will be just one coil in a conventional winding.
any suggestion?

Hi ariovaldo,
Cool. One coil. Suggestion. Yes. Wind in 2 slots only, span 90° mechanical. A very good idea for first test.
What model VFD? Possible to post photo of motor nameplate?

Allen Bradley
input 1ph - 110-120, 0.5 kW.
output 3ph  - 0- 230 volts


This VFD is the best option for small tests.

Nice drive. Motor nameplate?

edit BTW.
You may want to commission (set up) the drive and motor with the standard rotor in place. Get it running properly, then replace with your special 'rotor'. Often you must enter motor nameplate data into start-up or set-up menu. And choose mode to be open loop V/Hz.
I'll see if I can find the AB manual, or you have a link?

About setting the VFD up, I'm okay with that. That is my field of work. The last one that I did was three weeks ago. 3500 kW, 4160 volts. I'm very familiar with setting up and fixing that. Thanks anyway. The motor nameplate is exactly like the one in the picture.
