Circuit setups for pulse motors

[Nastrand2000]

Ren,
I create my coils with a drill winding them. I going to build a better jig for this setup. I will make a video of it. I tried using my camcorder to film the motor, but the video was 200+ megs for 1 min of video. So first I either need to figure out how to turn the cams settings down or how to compress and leave some of the quality.

cool. I might try the drill sometime, would definately save some sore hands. For compressing your 200+ file download a free compressor, I just grabbed this one. http://www.stoik.com/products/svc/

Theres a free version which lets you do most things. If your camcorder saves in common format, i.e. mpeg/divx/avi etc it should be easy to select the file, choose a save location and select form of encoding. Id go for one of the divx/xvids, the smaller the dimension (240 x 120 etc) the smaller the movie window, but the smaller the size. Hit record and let it do the rest.

By the way, I was wondering what the specs are on the cap you're filling? I got a bedini ssg circuit to work  last night, but it doesnt seem to keep rotations up unless I give it a really good spin first. I'll have to check all my connections and make sure the coil is close enough etc. It was interesting to play around with the pot and see the neon bulb (charging battery disconnected) change colour and intensity as timing was altered.

The one one cap I use most often is a 450volt 1microF. Its a tiny cap. However, larger caps can be filled. The largest cap I fill is a 24volt 1.5F cap.

I thought today I might try driving the motor off one coil and position the other three for collecting only. It probably wouldnt turn fast enough so I might remove the cores from the pickups. If I can get decent voltage off these air coils this would be an optimum setup with little friction.

I just built a 3 inch coil and am testing it on top of the 2 inch coil. The bottom coil will be for bemf capture as well as generated coil voltage from the passage of magenets. The top coil will be for capture of collapsing mag field.
