Hi Keyo77

so you think only one motor coil position gets pulsed, and the other halleffect and transistor are doing something else altogether??
Perhaps "recycling" the backemf of the motor/drive coils through the gernator coils in a "timed' fashion that makes it accelerate if you find the right timing()
What is your theory here... can you explain again simpler?

Using Romero's driving circuit for a generator coil half the cycle, when a magnet is approaching a core, the capacitor, of a 'right' value is being charged due to attraction and then at the right moment we use that charge to repel the magnet and power a load. Like in his video here: Speed under load! I think that this mechanism was some how incorporated in his device.

 yes in remeros  videos i watched (speed under load) he drives a small rotor with one coil and then with a totaly different circuit and coil he collects and helps push the rotor. i cant tell really whats all in the circuit but it has a hall sensor and i think a transistor. i also think its a bi filar coil. theres something going on with the generator coil that he is getting some kind of push pull effect or he is generating and pulsing at the same time. either way i think the timeing for it is done with that extra hall sensor

Hi Keyoh

OK thanks for the explanation its very interesting and makes lots of sense.

That 100uf capacitor - in "regular" motor coil circuit, why have one of these?...maybe a much smaller one to smooth the DC or somethign but 100uf is fairly large capacitor so that is somethign interesting right there -

and then that single diode is there too, so it collects "half" the sinewave of the magnet-sweep past the coil through that single diode and plops it into that 100uf cap....just as a generator coil would do with single diode into cap...

then when mosfet turns on to pulse the coil with some juice, it takes the power it needs if from that 100uf cap.

ITs totally possible to string all "odd number" of  coils together (like romero does) and pulse this whole string of coils against a rotor of even-number of magnets - I have done this a lot actually - and you will have a decent motor running like this....

so your theory seems to be then;  that romero pulses his whole string of gernator coils at once from that  "2nd" halleffect-transistor coil circuit....it only collects from half of the sinewave too - via that single diode - and the other half of sinewave becaomes a free-push too, since it has those "regauaging/backing" magnets behind the cores....

so there is "no lenz" since the gernator coils are busy getting pulsed in a motor-mode on both sides of sinewave that the magnet sweeping past the coil creates (one side pulsed in motor-mode from cap and mosfet,other side from "pulsed" from backing magnet)

the only time has to do any work that could possibly create a slow-down  is the filling of that 100uf DC cap and that is fairly easy if  you find good size cap that fills up non-reflective and also has enough oomph at discharge to move the magnet (100uf)....

this also backs up Hector's theory that is "all"  from the "reverse diode" in the motor coil circuit, the looping result.....

Hi highrollerscorp!

The circuit that romero used to speed up and powering the leds is the same as the driving one. The key is to make the ''right'' coil with the ''right'' capacitor. The coil is not bifilar. The trick is done mostly by the cap. I also done the same experiment back in august but after a while i removed the video becouse there is no gain there. Anyway, i found my video here http://www.youtube.com/watch?v=JpTw_Hf_CHo

In romero video there are two driving circuits. One is pulsed by the big magnets and the second one is pulsed by the smaller magnets. In my opinion, the second circuit is NOT used for driving the rotor. The small magnet is weaker and that means that the hall sensor will stay open a shorter period of time. I have seen this in my experiments with my scope.
