Excellent tests!...now do not get disappointed by your low output.
And I agree that you should not change your armature windings now, I believe the 34 ohms will allow much higher voltage for future tests.
Amazing the Inductance fluctuations just by hand spinning armature!!
Figuera's success is mainly based on maintaining SAME PRESSURE between both opposed fields.
From the above fact derives A lot of things involved) like each primary field MUST HAVE sufficient strength PLUS SPATIAL SIZE in order to Displace ALL ALONG Secondary axis...maintaining SAME HIGH PRESSURES.
So, NOT ANY combination of Volts-Amps will work for your SPECIFIC COILS-CORES mass (Volume) and length (SPECS). This also applies to any transformer or generator...if we do not get the right V & A to build the correct FIELD (can call it flux density if you will...) at primary or exciting coils for generator... it simply will not work...will not output nada.
IMHO I believe you should try different VA ratings at INPUT, until you kick a pretty decent output.
The only reason I used separate cores, was to test different size (length and thickness) Secondaries....but as long as you make coils that could slide off core...then different lengths of coils could be tested....remember, the shorter the secondary, the less displacement required....but you could grow in coil diameter since field expands beyond core.
I have tested what you wrote finally about MM opinion on secondary...and He is correct.
When we load secondary, (literally shorting it) we are generating a VERY STRONG INDUCED FIELD which naturally reacts with our Varying exciting fields...and so, by tendency it will affect more the "retracting"(decaying) primary since it is weaker and lower in flux density. NOW, This is NOT always good as it could throw off FIELD PRESSURES, dropping output.
I would test at INPUT a HIGHER Voltage that your armature can easily take...like 50V and like 2.0 Amps (about double of what you've tested)...then compare results ratio to this test.
Also, if you could measure your primaries fluctuations INDEPENDENTLY on Volts and Amps, (two meters V-A per each primary) it would reflect if they are balanced in HI-LO INPUT...I would test first at low speed...then operating 3600 RPM'S.
Wish you the BEST of results, truthfully and sincerely!
