Circuit setups for pulse motors

Hollow core is 1/16" thick and 1/2" diameter. Don't know why Snamaki had problems with his but I'm liking these ALOT!

Thick end of coil is closest to the magnet and they are all oriented N facing out. Overhang on other end of coil is 2" which allows me to mount them in a block of wood
I really can't explain why the BEMF I'm getting off the center tap peaks so high (I just disconnected the load and watched the cap go to over 20 V very quickly) off of 12V input but I'm certain it has to do with the Tesla effect similar to his findings on a bifilar pancake coil. Can't use a FWB rectifier in this situation. If I were to have two coils firing at the same time I could but until I start adding more of them it's not viable. Half wave still producing nicely.

Picking up some aluminum frame material to finish my 7' wheel. Made it once out of pressure treated wood but the wood started to warp and really messed things up. Not this time. 20" diameter, 1/4" thick rotor hub with 8 arms ( 3' long) attached is the new plan with the frame being 1.5" X 1.5" X 1/4" thick  square tubing. Will post pics once complete. Getting help to lock 1/2" drive shaft to rotor so that I can use the extra torque. Hopefully I'll be driving a windmill generator. Had to trade an older computer for this stock.

Keep on pulsin,

Oh, and by the way, both the optical and hall timing have one thing in common. They both rely on a drive ckt with will naturally have losses. It has always been my intent to reduce those losses and for that reason I chose the reed/relay combo. No drag and absolutely minimum losses. Timing to your individual needs can be accomplished in a variety of ways. Diectly off the rotor mags or you can add a disk with magnets and test various sizes for pulse width. Either way these new high current reeds are a blessing.
The only electronic parts other than the relays that I'm using are load limiting 5W 2 ohm resistors going to the charge batteries and of course the 10K uf 60V cap.
Hop this helps.

Well Carl I've tried them all and for me the best combo is an optical switch and a Darlington pair. (OPB490 series made by Optek Tecnology and a TIP 102).

I'm always open to different ideas..,
Would you be so kind as to draw this ckt. I'll test it for sure.
Bedini SSG  setup was my original ckt and had no way to attach (shaft) for any optical sensor. Guess I could just use strips on the face of the magnets for starters but my magnets have a way of shifting positions ever so slightly. That's why I'm moving to the big wheel. Maybe then I'll be able to test various other timing ckts.
Thanks for the input.

Sounds like your problem is physical- mechanical rather than electronic. An optical switch may not be for you. The best person to ask for circuit setups is Gyulasun.
