Hi All,

Just a quick synopsis:

Test 5 min ago.

Variable Power Supply set to 14.00 VDC.

Motor voltage      14.00 VDC, Generator unloaded voltage across cap..................................8.57 VDC,  RPM 2300
Motor voltage      14.00 VDC, Generator on RESISTIVE load to lower voltage to NO BOOST.....5.48 VDC,  RPM 2010
Motor voltage      19.48 VDC, Generator in BOOST MODE, Generator voltage........................5.48 VDC,  RPM 2513.

The difference the generator provides as a loaded device/Generator is + 503 RPM.......give or take in it's loaded state.

Gone for the day.

Morning Hoppy,

You are absolutely correct in your description of a non working system.  In the video, when I start it @ 14.00 VDC, you will note the voltage across the cap rises to about 5.4 VDC and the SUM of these two voltages is about 19.5 VDC which is presented/shown to the motor coils as shown on the second DVM in the back to the right.  The gain is that the voltage across the CAP is extra voltage seen in the loop from the generator.  IF it is not working, you will see exactly what you have described (total of 14VDC in loop) and I have seen so many times in this quest.  Remember this boost generator output is a totally electrically isolated system, separate from the motor, IN SERIES with the primary power supply,  hence the ability to add it to the loop.  Watch the two DVM's in the video again as I start the system.

Ben,

Thank you. Just to be totally clear on your setup, are you measuring the voltage directly across the two motor coils in parallel and adding this voltage to the voltage across the cap? You have three components in series, the motor coils and the two bridge diodes in series, which are both bridged by your cap. These components should drop the whole supply voltage between them. If there is anything over then this is a gain.

Hi Hoppy,

Correct with corrections, I end up with a series LOOP circuit consisting of the (1) Variable Pwer supply set to +14.00 VDC and (2) the ISOLATED generator supply consisting of 2 coils in parallel, phased the same, feeding bridge to a 68000UF cap. (the Generator coils/bridge/cap make a separate power supply) which under load settles down to about +5.48VDC,  the two above power supplies are wired in a series circuit + to -, + to - which means their voltages are additive (19.48VDC) and they share the loop and common current and are then connected to the standard PULSE motor driver circuit, which is 4 air coils in series driven by a Hall/Tip41 pulse circuit.  The load of the generator self regulates the speed of the rotor, etc. as it is still under unity and does not run away.  Everything is dependent on everything else and effects it!  How it all fits together  is really fascinating and gives you a very clear picture of the process.

Wife still not ready to go out for day...........in a holding patern.

I do not think wire has to be Litz, just have a old reel laying around from Xtal radio days.

Thanks Bolt and Guyla for your replies and further details to my direct loop connection question.
