@Rawbush
Thanks for trying a non magnetic rotor core. I still think this could be what accounts for several other factors also, like the high current draw (.94 amp) to run the unit.
At some RPM the coils should build a resonate flux like an induction motor and the output would go way up.
Or maybe only every other rotor location was a non magnetic core. Anyway, the possibilities in this device are endless, and we may never know how this really works.
Thanks again!

@gyulasun & all

Thanks for the info. Whilst on this subject of the bemf loop back diode, do you know how and where that diode is connected? Also, does anyone know why Romero's device takes in almost 1A without a load?  In the first video, just starting the motor with the battery with no load. That  seemed an awful lot of current for 2 driving coils and some mA to operate a couple of Hall devices? Is this a clue to sort sort of static biasing?

Hi ChrisC,

About time someone picked up on this.

How many pulse motors have you seen that, on startup, draw the same amount of current that is
used once the rotor gets up to speed ?

Has anyone else loaded the output directly back to the battery - via a diode or whatever ?

Is it for biasing ?

First i want to thank you for helping me. 

I took another shot with the output shorted by the same 10 ohm 5W + an large cap 22 000uF.

The signal has changed becouse i've changed the wires that goes to the sound card.

My coils 20mm high, 10 mm ferite and 600 turns. For each coil i get around 6,5V -6,8V witch gives me a total of 13,5V-14.0V for each pair with no load and maximum speed

The coils are hand made by me and the first layer of winding sits directly on the ferite bar. I know that the coils are not perfectly but seems to be working.

you're welcome, marius, tho' i'm not sure that i'm helping much!

could you use a DVM, if you have one,  to measure the DC voltage on your 22000uF cap + 10 ohm load, and let us know the value, please?

i'm not sure what you mean about the signal changing because you've changed the wires - do you mean like changing to a different pair of 'probe' wires?   (if you're using two separate wires, it would be better to use some co-ax cable, like a guitar cable, with the braided outer shield connecting to the outer (ground) connection on the soundcard and the central wire connecting to the 'tip' connector in the soundcard  jack socket)


your existing coils seem to be giving quite good output - you may possibly need some more volts, but first we'd need to know what sort of value you have for voltage on your cap + 10 ohm load


thanks

I have a question to those who have gotten their rotor to speed up under load. What happens when you move those coils completely away from the rotor? Does the rotor slow down or speed up?

Just a couple quick thoughts.

My wife specializes in intellectual property law and deals with patents every day. Unless RomeroUK was under an NDA, he did nothing wrong. In fact, he could take someone's entire patent and reveal everything about it to all of us and not be in any trouble, at least in the US courts. Patents are there to prevent someone from MAKING MONEY from the work of another. If you come to my house and steal my physical patent document, that's theft, but if you take my idea and build it, there is not a thing I can do about it until you try to make money from it, and THEN, if I have a patent, I can sue you. So he need not worry from a LEGAL perspective unless he violated a written agreement that he had signed. Or so I understand. Somebody have a DIFFERENT understanding? I don't want to give bad advice!!

In the Lindemann/Lockridge thread we have been working on the best way to build a motor to eliminate the effect of Lenz. Pulse the motor for as brief a time as possible to keep it running at the desired speed with HIGH voltage from a charged cap. Then collect the coil collapse PLUS energy produced "in the absence of applied voltage" by the movement of the magnet past the coil in a SECOND cap bank. With the off the shelf motors we're working with in that thread, I imagine we're looking for a supply pulse of 300+ volts. I have read through this thread from front to back, and don't think I've seen where anyone has tried that. Just a thought. I've been doing that with my off the shelf motor with good results. Just trying to work out the best way to charge a cap bank and dump it to the supply cap, and that is the same circuit I was thinking about for THIS replication. By using that high voltage for as brief a time as possible, a little magic happens, if you can get the timing right.
