Peter sent me a picture of his Bedini motor, with its colorful coil (see the attached picture). He says it draws 30 milliamps at 9V when running at maximum speed. There seems to be a large following of this Bedini SSG device, especially among the Free Energy advocates. It is called Bedini SSG, for Simplified School Girl. I’ve been following the Bedini weenies for a few years, and I joined the Yahoo group Bedini Monopole 3, which is now in the process of getting a forum up and running. It’s an interesting circuit, much like a Joule Thief, but it will not run without the magnet wheel. It runs off a 12V battery, typically a SLA, known as the running battery. The collector voltage is rectified and fed to a second battery, which is known as the charging battery. But I’m not sure what the device is supposed to accomplish, because it doesn’t generate free energy.
I tried building one using the innards of a CD drive. The Bedini instructions recommend that the builder cut up welding rod into short lengths and insert them into the core of the coil. Instead, I used steel wire, which was thinner. They recommend using two windings, one with 23 AWG and one with 26 AWG wire. Instead, I used three windings of 26 AWG, with two connected in parallel. They recommend using a 2N3055 power transistor, which has a collector voltage rating of 60 volts maximum. They recommend putting a neon lamp across the emitter and collector, as an overvoltage protection. This seems like a bad idea to me, because the 2N3055 is rated for 60V max, but the neon lamp lights up at 90V. They recommend using a LED from base to collector to prevent reverse breakdown.
My wheel was plastic because they tell the builder to not use a steel bicycle wheel. They tell us to not use neodymium magnets, but I used them because I did not have any other small magnets. The magnets must be a certain polarity, north or south facing out, I forget which.
I lashed up the circuit and powered it up. It did not work, and I did not pursue it any further, I just figured one of the recommendations I deviated from caused the problem. I do not want to pursue it again, because I don’t see what the point is. Also, I think the circuit needs to be redesigned for more protection. Many of the builders complained that they have burned out the 2N3055 and had to replace it.
By the way, Bedini patented the circuit, but they have said that he gave permission to build his circuit. They sell kits, and a lot of builders buy them and assemble them. Many of their pictures are posted to the group.
Thank you Peter. Someday I may dig out the parts and take up the soldering iron, and try to make a successful SSG. But not at this time.
Can you give me a diagram i want to build one these one. I followed everyones diagram but it wont work
This picture is Peter’s motor, I haven’t built one. There is a forum for Bedini enthusiasts called Overunity.com. Perhaps they can give you more information.
