Circuit setups for pulse motors

[Ren]

motors been running all day. Trying to condition car battery. Has risen from 12.30 to 12.65 so far. Run has dropped from 12.40 to 12.20

@ Ren  nice work

So here's my mini beast with three Adams bifilar coils. It's running at approx. 180 rpm
Supply voltage is 24 (two 4.5AH UPS batteries). Bedini 2-transistor drive ckt. each trans powers two coils in series leaving two windings hooked in series with a FWB feeding charge battery.
Charge battery is a Marine deep cycle 115 AH. It's slowly charging and will start to add my pickup coil today.
Tried the hard drive platter with little to show for it except the experience. Will post when I have something interesting. Still want to try the splatter coils but will have to wait on more magnet wire.
By the way.., I angled the magnets and the coils for  better firing and this helps with torque.

nice mate. Its hard to find the right hard drive bearings.  Most (old ones especially) are press fit into the unit and arent easily removed. VCR's have awesome spools in them which have excellent bearings, my next mini will be made on one of these. Got 1 kilo of wire delivered today, if anyone has any bright ideas on how to braid/twist 3 wires @ 300 feet let me know

Bearings, Arrggghhh...

The bane of my experimenting continues to haunt. Good news though. With the two transistor Bedini drive ckt I've been watching input and output current readings and they appear almost equal. Here's the problem. With the BEMF fed back from both trannies it slows the motor down substantially and we still have to deal with the .6V loss from the diodes??? Motor will spin for a veerrryy long time but so what! Sure wish I could overcome that loss from the diodes but alas, that IS why we try. Pretty much had it with the beast and have ordered a couple of 20" Plastic bicycle wheels w/bearings in the hope I can overcome some of my frictional losses. Two Adams style drive coils and one charge coil gives me much to work with. Feel like I'm close to overcoming most of the losses and will march on.

Hi All,

I hope those motors of yours are still humming away nicely. Ren I just wanted to thank you again for sending me the DVD of Bedini.
There wasn't really any new ground covered in the video that I haven't read about or personally experimented with before, but it was still a very interesting video to watch. Wow, what wouldn't I have given for a workshop like Bedini's. All my years of experimenting were carried out in the smallest of sheds, with the minimal amount of funding and limited access to machinery of any kind.

Bedinis workshop made me slather and froth at the mouth. LOL

Hows that mammoth coil you've been winding? Ready to ionize the world with a massive bemf spike?!  LOL 

Also Tropes, hows your sotropa experiments coming along. The last posting you showed some well machined parts ready for your next round of experiments. How's it all going? 

Cheers all from the Toad who Hops
