The Robert Adams Pulse Motor Design Review

[toranarod]

Rod your a foundation of open source, you will never die my friend, good to see you back thanks for the update...


Ash

Hi Ash

how is your work going. any news on Orbo?
Rod

[ashtweth]

Hi Rod, yes building the Calo meter now so we can accurately measure it, looks like the coil info will be in shortly too, got the SS boards done. Building a heater to measure .

[toranarod]

my latest up date

It been a while I just got over my bike accident and have just started to pick up where I left off.
Here is what I wanted to do before.



Green & Yellow Wave Forms
The green wave form represents the voltages being generated by the drive coils. Present in this wave form is the induced voltage being generated from the magnets as they approach the iron cores. Also seen in the green wave form is the switching pulse from the drive controller and the high voltage spike of 350 volts being returned to the source battery. This voltage wave form is present at Tap Point 2 as seen in the schematic below.
The yellow wave form represents the control pulse to the solid state relay. This control pulse present at Tap Point 1 engages the solid state relay to allow only the high voltage back EMF to be returned to the source supply. By switching the relay off during the induced voltage cycle, a load situation is prevented from occurring on the drive coils.

Outstanding work Toranarod!!!

Do you have some measured results?

Also, what resistance do each of the drive coils have?

Kind regards, nodrog :-)

each coil has a resistance of 0.5 OHM and an impedance when switching 280 OHM
If switched correctly.
cheers

[nodrog]

Thank you for that. I have no idea how you came up with the 280 ohms impedance. I'd love to know.

The 0.5 is surprisingly low to me as the lowest I have used is around 8 each.

I am guessing here but is the impedance increased or decreased by the pulse frequency? Since you seem to be making multiple pulses per magnet engagement with the stator.

That being so (stretching the guess off the edge here), would a single coil of 280 ohms with a single pulse give the same effective result (in theory)?

Kind regards, nodrog.

Hi Rod,

I think you need to look at this -

You have a valid point.
its about extracting the energy that can be put back. coil resistance is important and changes the returned current value.
it means my source power supply has .5 ohm resistance. Ask
this question why can you not start a car with 12 volts of dry cell batteries.
they my have the voltage potential but there resistance is to hi, Same reason
a capacitor can fire a rail gun its resistance is 0 ohms.

Hi Toranarod

It totally makes sense then that with your ability with electronics that you would use a low resistance then "dial it up" so to speak as the need arises or performance dictates.

So how did you come up 280 ohms?

:-)

Kind regards, nodrog.

Hi

Has anyone seen this page: http://www.totallyamped.net/adams/#top.

There are useful info about building Adams motors over there. I have personally verified the acceleration effect described over there, and I am investigating this matter. It even accelerates under load. Have you seen such effects with your generator coils Rod?

Hi Elias

Been studying that site. An excellent resource for an electronics novice like me.

Thanx :-)

Kind regards, nodrog.

Hello

when the resistance of the coils are important this relates to their length
which may be equal. The length of the coil determines the frequency of its standing wave (quarter wave) if operated in that mode (kapanadze coil)
Maybe there is an optimum, when operating the adams motor at certain rpms? (My thoughts)

There is a spanish experimenter , who claimes to have OU results .
Translate this site through google. El Motor Adams



1,7612 W Input 3,444 W Output


He mentioned that he got positive results since he used many windings
N=1000.
28 Ohms both coils together.

Look at the graphs . He is showing the voltage on the coil.
He assumes the current to be a constant, while switched on. (25% of the time)
Well if this not correct and the current would raise slowly to the limiting mark given by the internal resistance his efficiency calculation would be even better.

The energy goes into the circuit and when switched off the flyback is collected to the output. This is alternating not simlutanously. And while the transistor is closed Voltage and Amperage go in the same direction, which means heating. (Normaly) It is most likely that the heat is converted into electrical energy. If the watts values are real additional heating losses are less likely.He did not mention it , that it runs cool, or I missed it.

The conversion of heat into force , then electricity occurs in two seperate cycles.
The heating losses in the first cycle are convertet, which means , if this is possible,
there is no need to dimension the coils to have low resistance.
IMHO resistance is needed to get this conversion process startet.

When I have got my winding machine, I will start building one. His circuit is fairly simple.

Hello nodog
I have been working on the Adams motor so much I have been totally distracted from coming on the forum and writing.

The coils measure .5 ohm as a resistor with a DMM DC static resistance

A coil is not a Resistor. Capacitor is not a resistor. However we use both of them to draw current like a resistor in an AC circuit. Coils can be used to control current flow in frequency changing AC voltage circuits. You may know them as surge arrestors.
What I am really saying is the coils have 280 ohm of impedance. The Adams Motor is a dynamic circuit and even more when you get into his cold current reversal. The faster you switch a coil on and off the higher the resistance will go. The opposite is true of a capacitor. The coils resistance in my Adams motor circuit given the RPM and The Switching frequency of the PWM controller calculate to 280 Ohms. This is why my argument for precision control of the timing is so important

Hi Guys that all sounds very good. Both Robert and Howard Johnson independently came to the conclusion the the magnet could also be made to pulse at theoretically 1000 times its base strength. Both believed they had achieved somewhere between 200 and 250 times the magnets base strength. Thus there is a lot of potential when you hit the all right combinations in these motors. For his 10KW machine Robert was using 0.35mm Wire in his coils and each of the 2 coils was exactly 36 ohms. In series he has 72 ohms. He was not interested in counting turns but was working on a different theory of operation in these designs. Regards Russ

Can you go deeper in your theory.
When counting turns is not of interest, maybe the length of the wire is.
In the kapanadze coil , the one that is fed by the spark gap forms a standing wave , whose frequency depends on the length of the wire.

...have 280 ohm of impedance.

From what you have said, 280 ohms would only be at one specific frequency. Higher if higher frequency, and lower accordingly. So, if I understand you correctly, how do you determine that 280 is the correct resistance/impedance? Is there an optimum frequency?

Please excuse my not getting it.

:-)
