Maybe possible idea for duplicating effect of Holcomb and others

Hi Jimboot.
I haven't seen anything new from your testing lately.  If the low resistance of your coils is causing you problems I have a suggestion for you,  You could connect the parallel wires of each coil in series similar to Tesla's pancake bifilar coil.  Of course yours won't be a pancake but it will have twice the resistance it has with the single wires and 4 times the resistance it had with the wires in parallel.  This will also increase the capacitance of the coils which may or may not help the virtual moving field.  Not too sure about that part.
The WiFi just came back on where I am so wanted to pass that idea along while I had a chance.
Later,
Carroll

hi Carroll even in series they are only 1ohm . I've built a couple of the circuits using different rated fets and I've been testing on my 1kW gen stator. Not ideal but I'm learning a few things. May go and rescue another alternator.

1kv? Did you mean 1kW?

lol thanks just woke up. Maybe I should have coffee before typing. Fixed

Good morning All,

I finally finished the circuit and tested it with an old alternator I had to fix the brush set, it belonged to a 4.9 L V8 Caddy, so, it is huge, like 120 Amps, and have a massive steel rotor.
The alternator that they run on the videos are from smaller vehicles, lower amperage,  which have smaller rotors and higher resistance on its stator coils...

First, I wanted to make it run as a motor, before I got involved into the generator function, in order to observe all behavior...

So, I used one PSU to feed Rotor Coil, and another PSU for running the 3 Phase.

It ran wonderful, even though this circuit needs a lot of work for a better performance. First, the Source for all FETs are receiving straight power (not regulated)...so, the minute you start PSU it starts triggering, even the VR being at lowest point to the Gates. (maybe a higher resistor than 4.7K?)
Second, the FETs run extremely hot whenever consuming close to 10 amps, so, Heatsink should be pretty large...and still keep watching the temperature down or will blow them off. (And no, I did not blow any so far... )

Related to interesting behavior I have observed two things:

1- The Amperage on Stator is completely "inverse" to the Total Power to Rotor Coil.

a) Meaning, when I get motor running at high speed, say Stator PSU at 8.0V and 8A, while PSU to Rotor Coil is at 2.0V and 0.5-0.45A...If I lower the Rotor Coil PSU to 1.0V the Stator PSU will jump to 10A...
Shouldn't it be the opposite under normal conditions?...I mean, I lower Rotor Field down, less drag, less field strength...don't the Stator amps should also come down?...and of course, speed increases when I do that, since automatically 3 phase power goes up.

b) And so the opposite as well...If I rise Voltage on Rotor Field the Stator PSU amperage drops down...(I do this to cool FETs when running for  a while)

2- Once I have the motor running, compensated at a lower amps at stator (like 6-7A)...I could close all power to rotor coil PSU...mean, turn V-Knob all the way to zero...and motor still keeps running strong...as PSU does not goes to a complete zero, but, like 0.8V and milliamps.

I will try to upload a video later on...where I show these specific behavior.
