Now you've done it, I'm confused as hell on the construction details for
this one!
In the circuit and component diagram supplied by John, the rotor is labeled
as being a 2.5 inch diameter roller skate wheel with magnets attached - yet
the rotor is elsewhere stated (with pictures and diagrams) as consisting of
2 disks holding the magnets in place! The photo of the 10 year olds motor
would indicate a rotor diameter of around 5-6 inches (based on relative size
comparison with the 1 inch diameter coils) and the video shows a rotor speed
that looks MUCH slower than 4000 RPM. I would suggest that if the 10 years
olds rotor was indeed doing 4000 RPM then based on my experience both she
and her teachers would have FREAKED! - I've seen how dangerous rotors at
this speed/size can be if a magnet comes loose, particularly if the rotor
has a reasonable mass.
As for the circuit diagram and hookup, it seems pretty self explanatory to
me. There is obviously no direct generator feedback connection back to the
battery. So, how does the battery supply power to load and losses for such a
long test run? Either the total work done by the battery is tiny, OR, there
is a mysterious battery recharging effect in operation, possibly a result of
the short duration current impulses drawn from the battery. Try getting
someone to explain 'mysterious battery charge effect' to you, all I get is
closed ranks and zero information with claims of NON-DISCLOSURE
agreements between involved parties. Dirty pool!
Is it any wonder people get upset when they can't reproduce the device and
claim, and the inventor gets upset when people don't build it exactly as
they did. How would you start with this one, based on the available
information? - stick magnets to a roller skate wheel, or build a larger disk
rotor. IMO, the component diagram conflicts with the photographic evidence,
and the stated rotor RPM just does'nt make sense to me.
Also, there is no mystery behind a reduced motor input current when applying
load to the generator winding - IF the gap between the rotor magnets and
coil core pole iron is made large. I've seen this happen many times with
this type of motor. It's simply a flux decoupling effect under applied load.
What a mess. We can put people in orbit, but we can't seem to get the facts
straight on a simple little electric motor/generator. I guess I'm stupid
because I'm not 10 and I think too much, right? <g>. I'm not having a go at
you Jerry, I understand you only posted what you were given. Personally, I
just can't fathom the value in building yet another very low power battery
driven motor/generator, unless something interesting and unusual is occuring
in the circuit. If there is something unusual and interesting here, what,
where and how is it? Does John know? If so, how do I beg him to tell me?
Regards, Bill.
