On page 8  it shows 2 dc motors shaft to shaft to demonstrate Lenz at work.

Then i got to thinkin,  are these motors brush timing proper for generating vs being a motor?  Just wondering if different timing  would make for a better gen.

The experiment is merely to show Lenz's drag in a conventional system. You can spend more money on a single DC motor for Driver and a Single DC Dynamo (or AC alternator) for the Generator - but the result will be identical. It's simply cheaper to use 2 DC motors, as it is not the efficiency of the motors or generator that is under scrutiny in the experiment, but rather, how much Lenz's Law affects conventional closed system generators.

It was just a thought as to if there is a difference if brush timing were different using one of the motors(as prescribed) as a gen. Would the drag(Lenz) be different.

Also, shaft timing from motor to gen may make some differences.

I dont believe that it will work, unless 1 or both are modified in some way.

See, my Grand father told me that his Dad had it. 2 motors at the shaft, all wires to a box with a switch. Flip the switch and give it a whirl by hand and it went. He was threatened for showing it, back in the 1910s.

This is the only reason that I still ponder how.  ;]

Indeed, from what you've just said, I'd be pondering too.

Hey Marius

If you remove the bolt away from the rotor, does it speed up also?

Just thinking.

The bolt could be adding drag, and the coil helps to reverse the drag situation. As in making the rotors attraction to the bolt(core) go away.  Not that im finding fault. I like what you have shown. But, is it the drag situation that I described?
And is there a difference in speedup if the bolt is removed as compared to shorting the coil?

Also, ;]  is what we are seeing speed(freq) dependent?

Very cool stuff.  There is another vid you did a bit ago that I have to go and see it again to remember the question I had for you , but didnt get to it then. 

As it seems that the coil needs near 1 ohm or lower, maybe try a small dc motor. Coil to bridge, bridge to cap, cap to motor.  The low ohm of the motor will keep the cap low enough to be seen as a load(near empty) and the cap will help to drive the motor.  You can try the bridge direct to the motor(pulsy) but the cap will help.

Awesome work.  ;]

Hi Magluvin!

If i remove the bolt it doesn't speed up, and yes,The bolt alone ads drag to the rotor. A cuple of weeks ago i made a video were the rotor speeded up  under a load; it turned out that a capacitor was doing the whole trick and there were no magic there so i removed the video. Now i found myself very busy this days with no free time al all.But it will end soon and then i'll have time to play with my rotor. Keep up the good work guys! Work in progres!!
