This work is a continuation of the excellent work done by Gotoluc. It shows the effective advantage of adding magnets to a circuit. In this video magnets are used to create work that could not be performed by using a metal rod alone. This same method can be used to increase torque on a pulse motor, all without increasing power.
Here's what I came up with for the circuit. The 74ls93 counter part of the circuit is where I'm uncertain. I kind of threw that part together. lol With this config I was shooting for the battery to go 12 pulses and the recovery cap to go for 4 pulses. I think it's close. My version only has one diode for bemf recovery on the positive side. I tied the relays bemf into the recovery too which I think will work if you use mechanical relays. It can't be a real fast motor with mechanical relays. I tried to design it so the bat would get a charge from the bemf when the recovery cap was the coil driver source. Like I said it's your baby and this is only food for thought. Hope I put this in the right area. If not I can repost it or you can delete it. It's up to you. Any how you got me thinking about it so I threw it together using ms paint cause my pc crashed the other day and I had to reload. Can't remember the name of the free schematic program I was using in order to reinstall it. Least of my worries now. Talk to ya.
I edited image to "fix" counter circuit. You probably didn't see the original. Just as well there was a problem. This version looks better to me. Still don't know if it works. lol
Hi Jim, Thanks for taking the time. It's at the right place. I will use some of your ideas. I'm not in a rush to do anything. To tell you the truth. I have a million project that I want to do. I have all the time all in the world to do it. I believe in OU and do not doubt it for a single second. Now, I'm concentrating on a the goal to achieve 99 % efficiency. Baby steps. OU, It's in our face everyday. I look at other's work for techniques, breakthroughs. But mainly for inspiration. I will achieve my goals and beyond. I always have. It's a matter of patience. Of course, it is all here, available to you Jim, and everyone else.
PS: I prefer Linux over MS, but I like mspaint because you can do quick sketch without skills.
