Circuit setups for pulse motors

[Ren]

Hmmm... lots of questions. It depends on how you are going to drive your device as to what voltage you can use. You will want to select the appropriate components for your particular experiment. As far as reducing amp draw, well this can be done a number of ways. A simple potentiometer will allow you to adjust current draw, another way is to reduce the length of time your primary battery is running closed loop, ie pulsed application.

A good way to build up charge is to pulse power down one winding of a multi filar coil and collect the collapse off another. Have it go to a high voltage bridge and store in a capacitor for future use. In this sence you are isolating your power from your source, which can have interesting effects.

Im not sure I understand your statement about wrapping your coils right. My coils are wrapped, The gauge of each wire picked for specific reasons. You cant pump alot of current through a thin wire, and perhaps a high voltage motor could benefit from this. For now I limit myself to learning with 12 and 24 volt because of safety and funds. High voltage can be very dangerous if you dont know what  your doing.Send me a pm if you want some simple design to replicate that will help you understand the basics.

Getting some great results from my Bedini wheel on 24v. Ive realised that if 1 wants mechanical power a higher voltage is desired. It can run quite efficiently on 50 ma with decent speed/torque. Also my window motor is going well, it can be tripped into solidstate quite easily and has very interesting properties!

Ive uploaded another video to you tube, I'll have to make some more.

Hi Ren, can you post the links of your you-tube video's ? I am very interested!

Thanks,
Robbie

@ Ren:
   Nice Video!  I really like the quality of your motor!  Do you know where I can get some cheap acrylic like you got (about 1" thick).  Looking good!   

   To clairfy what I was suggesting, I read your posts about the bifilar coils, but I was thinking of something different.   Check out the pictures I made (poorly).  Just a thought......  When I come up with a good test on all the coils I am makeing (painfully) I will share those results.   

    I looked everywhere for Pots and Resistors and Diodes.  I don't think I understand enough to make an investment into them.  So far, it looks like I will be running 12 volt 25-50 amp per coil (rough guess).  Your direction to the pots got me thinking about a light dimmer switch on a car.  I think that should work perfect and it's free (just what I need!)  Anyways, I do appreciate all the help your giving me, I wish I was an electronic genius....

   Lastly, I found a cool place to do all the hard math for us.  If you look on the left side  it will say "Technical Calculator" http://www.riedon.com/us/index.php?option=com_content&task=view&id=3&Itemid=4
Looks like any kind of math you need to do to figure out your volts/watts/amps/resistance/etc can be done here pretty easy. 

Thanks again for all your help Ren!!!!

Hi all, glad to see you're keepin on keepin on!

@Ren - I just checked out your latest vid - nice machine work mate. A work of art if I do say so myself 

@Bakercool - I haven't got much free time right at the moment, due to relatives staying with us over the long week end. Gotta do the right thing and play the cordial host and show them around the local sights etc. I'll try to give you a few little pointers about running motors on voltages higher than 12V when I get a chance, and also about using your output coils as step-up transformers.

Just a little word of caution that has already been pointed out to you - be very careful. The sort of voltages you get from the collapsing field when using pulsing DC in a step-up transformer configuration can be extremely high and very, very dangerous.

P.S. Car pots for dimming headlights tend to be wire wound, low impedance pots if you're ripping it out of an old vehicle. These are generally not very suitable to control the transistor/mosfet base.

Linear carbon track pots from your local friendly electronic outlet are usually only a dollar or two to buy, and are much more suitable for controlling the base current/voltage of your transistor/mosfet.

In the meantime, keep on keepin on! Cheers from the Toad Who Hops.
