New Newman Motor Replication

[onlov]

Maybe better way to get additional (back_emf) energy from coil and put it back to battery:

Wonder that Newman motors uses only half of possibilities - why half-bridge drive? Why only Push or Pull -  Why not Push and Pull This is mystery for me - why geniuses do not use all what God is sotto voce telling. Of course, when read about he (JN) does not know much about back-iron - how he can know about using back and forth effect for rotary drive - because he uses only one-way ticket  When full-bridge (H-bridge) drive then instead Push or Pull will come Push and Pull  forces -  twice more torque. And why these commutators ... why reed-switches? Why not hall sensors or opto-relays? Next step is to use Back EMF for timing - get sensorless drive ...
When outer side of (motor)windings coated with laminated back iron - then we?ll go more close to common motors. Huge number of different brands!
Instead of laminated back iron could be used rotating back iron - more less iron losses ...
like ThinCap motors, like Maxon coreless BLDC ... like Kontronik Tango (RC motor ;-)
When to use 3 similar motor windings - we?ll get common 3 phase slotless motor.
Look at Takao Shimitsu - normal guy from Japan - what he is doing -  http://www.cityfujisawa.ne.jp/~iijima-p/BRA2.htm

These schematics are maked for beginners (for Careica) who understand nothing about H-bridge and electronics! Of course, H-bridge, hall or opto sensors are much better and modern solution...

Newman motor is really old and ineffective solution. With iron as you tell it will become much more better...

Back_emf pulse have wrong polarity to charge the battery. Plasma spark only spend electricity (voltage loss) and makes only heat. And burning the graphite (=carbon) makes only heat, not electricity. And "plasma battery cell" can have wrong polarity with battery (and with voltage loss of plasma spark) and decrease voltage...

Man who are studied at the technical university of Berlin, speak lot of nonsenses about the Newman machine and OU...   

Onlov,
the difference between me and you is, that you only rely on the theory you have learned,
but I did indeed test it with hardware.

Normally I would say you are right,
but the test with the hardware says the other way around.
The sparking gets additional energy into the circuit and recharges your batteries,
if you setup the sparking commutator right.

Have a look at these scope shots I got from my setup,
where you can see the huge negative current spikes, that recharge the batteries:
















All these negative spikes are real back current spikes
charging up the battery.

Stefan, I have seen these pictures before that thread. But I will see your metering circuit.
You are telling, back current spikes disappears if your scope is grounded. It's very strange effect.
