Magnetic viscosity is a well established phenomenon.

The idea of the phase delay due to it is my own idea, but I am sure that others have considered it as well. I didn't think it was viable since I was expecting it to be a nanosecond delay...not microseconds. At microseconds and 100s or 1000s of Hz, it could make a very significant change to the integrated drag force.

It is also interesting that the thing that makes this work as a generator would be seen as losses in a motor. The very reason that pulse motors can approach 100% efficiency is due to the ability to tighly control pulse phase and duration, thus eliminating those losses.

As for all of the smart people that haven't seen this...well...how many overunity devices have you seen? I'm just suggesting reasons why RomeroUK's device worked...not trying to explain the 99% failures.

Agree, but delay depends about materials you use, ferrite, at least by my opinion, is the last material for to use in generators and motors.
I do not name myself as smart guy,
I havent seen any OU,
I have not seen Romeros device works, just bad quality videos and messy talking about,
When in some video half of magnets missed, then ... "tuning!" :o
I cant speak it does not work or it does work, may be, but ... I do not believe,
I did read many times all his posts ... every time found more and more incompatibilities,
He does not remember what he spoke last time or last week, comes nervous  when to ask ... speakings about huge lot of work experience ...
And ... like again and again  - a visit of cruel man in black 8)
of course, this just my opinion,
We´ll see  ::)
cheers,

Today I got my bearings with a 12mm rod. I mounted to my rotor with magnets already positioned.

Now I am going to work on the top/bottom stators and the stable station. Later insert the relay coils and give it a spin.

Fausto.

According to what I am suggesting, the ferrite's high coercivity, and because of that a tendency to cause a phase shift, would be the very reason that it worked. Is that best for motors and generators? Conventional ones, no.

You have made it abundantly clear in the other thread that you don't believe, and it is your privilege to choose not to believe. Myself and others are discussing reasons why it might work, not discussing why it can't. I would respectfully suggest that you drop that, especially when the moderator has asked that the focus remain positive.

Working now on the stators. Tomorrow I will cut it and mount the whole station. Hopefully even run a single coil or two test.

Fausto.

LtBolo,
Looks like you do not use soft ferrite but hard ferrite  :o
cheers,

Soft ferrites
Ferrites that are used in transformer or electromagnetic cores contain nickel, zinc, or manganese compounds. They have a low coercivity and are called soft ferrites. Because of their comparatively low losses at high frequencies, they are extensively used in the cores of switched-mode power supply (SMPS) and RF transformers and inductors. A common ferrite, chemical symbol MnZn, is composed of the oxides of manganese and zinc.
Hard ferrites
In contrast, permanent ferrite magnets (or "hard ferrites"), which have a high remanence after magnetization, are composed of iron and barium or strontium oxides. In a magnetically saturated state they conduct magnetic flux well and have a high magnetic permeability. This enables these so-called ceramic magnets to store stronger magnetic fields than iron itself. They are the most commonly used magnets in radios. The maximum magnetic field B is about 0.35 tesla and the magnetic field strength H is about 30 to 160 kiloampere turns per meter (400 to 2000 oersteds).
