Circuit setups for pulse motors

[Nastrand2000]

bakercool, with my experience I would suggest you never cross the the 1 amp pull for this type of motor. Especially with a prototype motor. You will only end up burning out the circuits (transistors) you are using  to switch the power with. I would suggest getting the rotor moving then drawing what you can from small input. Then upgrade to larger input.

from only small input of voltage and amps, these motors can be deadly. For instance, I put in 5 volts at 100 Ma and get out 300 plus volt. That is enough to restart you heart if you touch the wrong things.

WOW!   

All the responses are awesome!  Very helpful to.  I don't have a parts store near me, so everything I buy is on-line (I live on an island north of Seattle).  I have a little voltmeter thingy (I swear I'm not a newb!  ) so It is hard to tell my volt/amp.  Hence the pot....  I believe I can get her going with 12v/6-10amp. 

@ Toad:  I looked for a pot that is for 12v-6/10amp, but could not find it.  Thanks for the heads up on post Toad on the wire wound!  I guess I will have to keep looking...  It's really hard to find parts when your an idiot ya know     If anyone *cough*  Toad  *cough* happens to find a pot that is like what I am describing and sends a link, they get 10 cool points!   

@ Ren:  After watching your latest video, I was wondering why you don't put more pickup coils around your machine..  Wouldn't that increase your output?  Configured more like a standard alternator/generator?  I'm also wondering about the picture I posted last time, and separating the outside pickup coils into 2 sections to pick up the +/- of the collapsing force.  More-so the field originally generated by the electromagnet.  Isn't that the same as a magnetic field theory in an alternator?  I can't test those theories until I have built coils worth testing it on...  Your pretty smart, so I figured I'd run it past you first....

@ Jason:  Same thing on your machine... Is there a reason you don't put more pickup coils around your machine?  Every movment of a magnet without it utilizing a pickup coil is a loss of efficency isn't it?  I wish I could test it and let you know, but I am very far behind you guys..   

@ Nomen:  Thanks for the suggestion about the relay steel, I will check it out! 

@ Everyone:  The coil testing is now moving me away from high volts/amps, and is more configured on a perfect blend of turns, core, gauge, volts/amps (nothing new to you guys I'm sure), but I have learned that the perfect configuration will actually be substantially lower that what I had antipated.  Thanks for the warnings & hazards...  If I electrocute myself to death, I'll let ya know.. haha

Lastly.  WOW!  Do I have some interesting outcomes with coils!!!!!  I'm about 1/3 done testing and need to do some more before it is conclusive, however, by testing differnet configurations, I had one coil approx 1/2 inch thick was fluxing at approx 12 inches away!!!  Strong Flux!!!  (even accidental made a magnet gun/bullet.. haha).  Some of my theories were dead on, some exceeded my expectations, some were a flop....  I'll keep the press on till I get the highest quality coil, then share my results.. 

I'm about to buy a whole bunch more magnet wire (about 3000') at a different gauge (probably 24) and Re-Do all the test I have just run...  I'm really starting to dislike making coils!     Anyone want to make about 50 more different kinds of coils for me???   

Thanks again for your inputs, everything is of help to me right now...

the reason?  $$$$$$$$$$$ . Lol. I dream at night of the copper fairy that leaves a 10 kilo spool under my pillow. Yes more coils will increase input+output. They require more precision in timing and layout, and if I havent throughly tested one single coil then I have nothing to compare the multicoil setups to.

Baker, get online (google or alternate search engine) and search for multimeter tips or tutorials. Learn the correct way to read your amp draw. FYI,  a motor that draws 6 amps @ 12v would require a 120amp hour battery to stay within recommended C20 discharge rates. Aim to get something that draw 600 milliamps before you even look at 6 amps, or 1 amp even.

If your coils are heating up then somethings not right, your flowing too much current through them.

24 gauge is a good starting point. And in regards to the pot, that should be obtained once youve built your circuit. Learn about ohms/resistance and things will make more sense. You'll probably look for a 1-3 watt 1k or 2k ohm pot for a basic circuit, smaller ohm (500, 200) for fine tuning.

About your pics, I can only say this. There are some interesting suggestions that if the weight on the secondary is equal to the weight of the primary the coils can resonate in tune. Position of these coils and how they are aligned with each other is something you will need to test yourself, I have not extensively tested them myself. Try your picture out. Use a thick wire on the outside and a thinner wire on the inside. Pulse the outside wire and send the inside wire to a bridge/cap. See what you get out. To do all of this correctly you will have to know your meter, so if you dont as yet, go study up!

bakercool,
Making coils is easy if you use a drill and a coil jig. making the motor spin should be no problem. I live in oregon....not far from you. i am will to open up full voice or type chat with you to help you get it running. just let me know.
