It could also be a question how the 2 drive pulses from the 2 drive coil pairs interact to each other, e.g. if the ON- time overlaps somehow which could have some kind of generator effect on the other drive coil pair and lower its input current.

Too bad that Romero did not post a dual trace scopeshot of the drive coil currents.

if you are worried about the ON time then use a hall into a 555 and set the pulse width adjustable from like 1mS to 100ms. Now you will get perfect ON and OFF time.

Then while you at it may as well short the coils on the sine peaks and get 10 times more volts out of each coil for less i/p lugging. Oh go the full hog and use switched o/p caps and load timing!  Now its easier to use a processor... too many things to be turned on and off:)

Separating driver and generator:

Having two drive coil pairs in Romero's generator introduces a lot of complexities as some pointed out (timing, overlapping of on time, how many drive coil pairs, back EMF harvesting, and os on).

Therefore I am thinking about separating the drive mechanism from the generator mechanism (as many others have done, also Romero, in earlier designs).

- The drive mechanism could be a simple DC-motor controlled by pulse-width modulation (just more ore less pulses of the same length per second to keep it simple). The number of pulses per second will define the power consumption of the DC-motor and its torque.

- On the axis of the DC-motor a disk with 8 evenly spaced magnets (a disk like in Romeros`s motor) is placed and rigidly fixed.

- Two stator plates (on each side of the rotating disk) hold 9 pairs of generator coils. Biasing magnets can be placed on the outside of the coils if wanted.

This design will have the same advantages concerning the strange occultations of the generator coil pairs by the magnets (which is supposed to reduce cogging and to give an elevated Voltage when all coil pairs work together). But driving the DC-motor at various speeds and power inputs (by varying the pulses) will be rather simple.

A MOSFET and a NE555 (or a modern equivalent or best a microprocessor) can easily drive the DC-motor and no sensors will be necessary.

Only one variable has to be altered, and this is the number of pulses per second (with a fixed pulse width) driving the DC-motor. One can then monitor the output of the 9 generator coils for an optimum (power fed into the DC-motor versus combined output of the 9 generator coil pairs).

I know, this is not a new idea, but it is much simpler to build than what was discussed and done so far:

- fixing a disk to the shaft of a DC-motor is simpler than mounting a disk with a bearing or two bearings

- no sensors

- it is very simple to drive a DC-motor with pulse width modulation

- true separation of driver and generator

My speculation: The uneven relationship between magnets and generator coil pairs is the "trick" to have a generator which needs less torque to get a certain output than a conventional generator. If this is true, it should not matter which driver one uses. Mixing "driver coils" and "generator coils" around the same rotor will introduce complexities which are hard to analyse and hard to solve and should be avoided in a proof of principle attempt.

I see only two possibilities for OU in the Muller motor:

1.) The uneven relationship between magnets and generator coil pairs is more efficient than any conventional generator (and therefore leads to OU). ---> use any convenient drive

2.) The pulses motor type drive coil pairs are more efficient than conventional motor principles (and therefore lead to OU). --> use any convenient generator

Either 1) or 2) should lead to OU. If both lead to OU one could build a machine which is even more OU.

That 1) and 2) are necessary in the same machine to make it OU is hard to imagine because the two principles seem to be independent from each other (one is a generator principle and the other is a motor principle). And even if 1) and 2) are absolutely necessary one should have two disks, one with the generator coils around it and an other disk with driver coils around it, just to have less interference. The two driver coil pairs seem to hinder a "balanced flow of energy" through the seven generator coil pairs and vice versa in the Romero design. It is also hard to justify why coil pairs 1 and 6 should be drivers and not any other two pairs.

Romero himself told us that one could focus on the generator part, and don't spend too much time on the pulsing part. It's somewhere in the first posts if I remember correctly

To ALL:
This generator can be driven by many other circuits or from an external motor connected to the shaft.Don't concentrate too much on the circuit used to drive the coils, that is simple.
People replicating this should have a little bit more big coils (size and windings).
Each coil in my setup has an output of 11.1 -11.6DC after the bridge, not all the same as I have small diferences or misscount some turns during the making of the coils.Having them in parallel I get about 15volts at full speed.The amperage is good but I would prefer to have a bit more voltage.
Diodes on top of the bridge rectifiers are not 1n4007,  are 1n4001. I am sure I can get better rectifiers but this is what i had.The voltage drop is quite high and nothing works as it should.
e to do it tommorow as I have stopped working now, I am too tired now.

That's the message I was referring to.

He also said in another message :

"After answering to jorge message I realised that I need to post the answer to his question.
Can i use power supply?
Actually for the preliminary tests it is a must to use a power supply that stays stable and you know that the voltage is not going down and nothing is changing."
