New Setup

My device is taking shape...

Ive read that you can, but the gate voltage has to go higher than the source voltage. I am not going that direction, I ordered 10 p channel mosfets today. They are twice as expensive as an N channel with similar specs. Why is that?

Thanks for the responses!

hey guys, can a N channel mosfet switch + ?

Ka J,

Yes it can, this is the basic N channel H bridge

As was pointed out the gate is referenced to the source so one uses a
"high side" driver like an IR2117

I seriously think you will get into probs there. The gate is in reference to ground. You would then have to put the coil between the source and ground and the drain to positive , not a good idea. But then I have never done it either. Interesting idea for sure.

My build is moving forward as well. Tomorrow I am going to laser cut my new setup. A new out runner motor has arrived as well so in a few days I should have a video ready about my acceleration effect achievement.

hello Shadesz

been very quite lately on the thread.

Some times I need to work on the motors and generators and talk about them later. That,s what i have been doing.

how is your work going?

Hey Rod,

Yeah. I figured there was enough theory thrown out there recently that we should wait a little while and test/digest it before trying to break more rules.

My build hasn't made much improvement. I still haven't been able to make a good homemade magnetite core I'm going to move on and just use laminated iron cores. Anyone have suggestions where to get them? Thanks in advance.

Hopefully your testing is going well.

Rod, Elias good to read you guys

I found this in one of Tesla's Patent; i don't know if it is useful, you let me know

Tesla Patent 685,012 - Means for Increasing the Intensity of Electrical Oscillations

It is well known that when electrical impulses are impressed upon a circuit adapted to oscillate freely the intensity of the oscillations developed in the same is dependent on the magnitude of its physical constants and the relation of the periods of the impressed and of the free oscillations. to make its inductance as large and its resistance as small as practicable. Having this end in view I have devised and used conductors of special forms and of relatively very large cross-section; but I have found that limitations exist in regard to the increase of the inductance as well as to the diminution of the resistance. This will be understood when it is borne in mind that the resonant rise of current or pressure in a freely-oscillating circuit is proportionate to the frequency of the impulses and that a large inductance in general involves a slow vibration. On the other hand, an increase of the section of the conductor with the object of reducing its resistance is, beyond a certain limit, of little or no value, principally because electrical oscillations, particularly those of high frequency, pass mainly through the superficial conducting layers, and while it is true that this drawback may be overcome in a measure by the employment of thin ribbons, tubes, or stranded cables, yet in practice other disadvantages arise, which often more than offset the gain.

It is a well-established fact that as the temperature of a metallic conductor rises its electrical resistance increases, and in recognition of this constructors of commercial electrical apparatus have heretofore resorted to many expedients for preventing the coils and other parts of the same from becoming heated when in use, but merely with a view to economizing energy and reducing the cost of construction and operation of the apparatus.

Now I have discovered that when a circuit adapted to vibrate freely is maintained at a low temperature the oscillations excited in the same are to an extraordinary degree magnified and prolonged, and I am thus enabled to produce many valuable results which have heretofore been wholly impracticable.

Yes, it is sometimes better doing than talking. I have been doing some experiments about this phase shift phenomenon with a push-pull circuit that I have made, It was really interesting, because I used a transformer and the secondary voltage shifted as the frequency went higher which was an indication of the delay present in the core material. I could shift it easily about 180 degree, but the problem was that it was unable to provide good amount of current in that frequency (about 90,000Hz) It could light up LEDs though while consuming less current in the input. When you shifted so that it got more than 180 degrees the output voltage started to diminish.

Lately I have been think of using a Rodin coil for this purpose, it is claimed to have much higher inductance for the same length of wire, therefore increasing the L/R ratio.

Will post some results tomorrow.

Hi all,

I was wondering when using the RomeroUK setup (over/under coils) if anyone tried to offset the top or bottom generator coils a few degrees to spread the break out force needed by the magnets. This would be the equivalent to using even/odd numbers of coils/magnets and possibly combine the effects.

Just an idea.

Take care all,

Michel

If I remember correctly, Romero recently said he was going to try that himself. I wonder if it will cause excessive shaking...

Hi all,

I've come up with the basic math of how we can achieve OU. The fundamental principle is we can put more momentum into the rotor than extract from it while the amount of input and output are the same.

If charge q = I x t where I = current and t = time
Then It = iT where I = input current, t = input time, i = output current, T = output time

The statement above shows conservation of charge and input = output. We extract little current for a longer period of time while put in large current over a short time.

What enable us to achieve faster rotation comes from the square term of magnetic force created by the coil.

Force is proportional to current squared.

Detailed equation: Electromagnet - Wikipedia, the free encyclopedia

If momentum = force x time
Then the momentum ratio or COP = momentum in/ momentum out
Ft/fT = I^2t / i^2T where It = iT
I= iT/t => I^2 = (i^2)(T^2)/t^2
I^2t/i^2T = T/t = I/i
This shows the ratio or COP equals current in/ current extract. If this is correct, then it establishs the basic math of how OU can be achieve.
