Joule Thief

[detrix42]

What happens?
Nothing?

when I hook up the other transformer, all I get is the input voltage, but I am not to sure if I have the second transformer hooked up right.

You do understand that the joule thief is giving you pulses, don't you?
Pulsed volts are very different from battery volts.
If your motor requires 340 dc volts, you will need something like kooler's, but much much larger.
How many amp hours are in those batteries? and how long does it take to run them down?

Yes I do understand that the joule thief is pulsing/osculating, and as far as I know I need that osculation to go into the other transformer to step the output of the joule thief.  Going from 6.5v to 100v is awesome.  The theory of a Newman motor is to uses as little current draw as possible. Right now the coils resistance is up to 1155 ohms. As I add more wire, the resistance goes up and the current draw goes down.  According to Newman, all I need is the voltage, which is why I eventually I want 1000v with just milli-amps of current. (micro-amps if I can get it that low).

Really a brush motor is a heavy amps user isn't it?
There are virtually no amps to be available from a joule thief.
What am I missing?

At the moment, yes it draws a lot of current.  I did a crazy test.  I uses a 330uF cap, and using my JTC I charged the cap to 100v. then took the cap to my motor, and applied the cap as the source.  The motor moved just a little bit.  330uF * 1155ohms = .38115 seconds to discharge the cap.  Again, once I add a lot more wire, and get resistance up, the discharge time will increase, and once the motor gets going I will only need a fraction of a second to keep it going.  I am very happy that the motor move a tiny bit.  Very happy.  things are on track. Now to get that other transformer to work. 

I also plan on getting a automobile's ignition coil as my JTC coil.  Or one of those disposable camera transformers. 

BTW, the coils are beautiful. You must have a lot of patience...(or chocolate  )

thank you,

And thank you so very much for the kind words.  I am impressed with seeing the LED in your plants pot.  Great job.

How many volts do you want and at what frequency?

My highest voltage was (unmeasured but estimated at) ~2000 volts and about 1.2Khz frequency.
There aren't any more of those toroids around but you can get one that would give you ~900v-1100v.
Would that be enough?

a mot primary and a yoke  and 5vdc pulsed by hand yeilds over 2000v

as per my tests long time b4 the jt

regards!

i built it from JUNK

LOL WHAT HAVE YOU DONE ?  i built it with out a transistor what have you done ?  i built it with a single wire what have you done ?


just incase you for got i built a pulse motor with 1 single wire 1 reed switch and 1 aa battery that it wobble tuned

good god

what have you done ? 

thats 3 freqs from 1 single  in 1 wire .. and then i made the damm thing self run

AGIN I ASK WHAT HAVE YOU DONE ...


and GUESS WHAT ....  : ) MY GIVE A DAMM IS BUSTED!

i want to feel something ..  let me digg a little deeper...  naw still nothing ....

I do need it to be DC power into the motor.  With a large enough cap, perhaps a supercap, I can capture the pulses from the JTC.  A drawback to the larger caps is the longer charge time. 

Ok, I just made a change to my JTC, and the cap charged a bit faster.  cooooool.    I changed my 1k resistor to a 10k.  and I now have a 14v input (2 used 9v batteries).  Its a 200v cap. hmmm.  And the cap charged to 114v.  cooool.  Getting there.

show me what you did please.  pretty please.

    If you change your motor to run on high frequency it may be easier than making a jule thief which produces real highfrequency from low current.  A high frequency motor is what they use on aircraft because they are smaller faster lighter and pack a bigger punch per pound.  They operate at about 40ohz.  A pulse motor can operate at thousands of hzs.  The steel core is what holds you back.  Some day not too far in the future there will be ceramic motors of 100s of horsepower that way 30pounds.  The magnetic bearing and hightech ceramics is making this doable.  The pulse motor links usually to a flywheel that changes the hf pulses to a more usable form of power.
