      holy smokes! this build is incredible! are all those transistors matched? What's the part number of them? No heat sink? Maybe you just run it at low current draw....you must use this to charge some bigger batteries. Any particular reason you went with a iron core rather than air core?

          Ooh, such a beautiful machines. These old dynamos pictures are pretty. And on the sparkmuseum link there are so many pulse motors, some of them even doing flux gating. Motors by Daniel Davis. The french one from 1850's looks like SG.

          This is a great material to study. Thanks for sharing the links guyzzemf !!

          There are also some amazing books shown on the sparkmuseum site.

          http://www.sparkmuseum.com/RAREBOOKS.HTM

          Seems these were the real science books talking about two kind of electricity, magnetism of earth and heavenly bodies, attraction and repulsion of animals and plants, etc.. It does sound familiar to me. I suppose Tesla and Leedskalnin have read these books.

            i was going to post this link when i finished the read,a good book
            Davis's manual of magnetism: Including also electro-magnetism, magneto
            http://books.google.com/books?id=pG6...page&q&f=false
            the original PMH is in this book PG-81

              Hi guyzzemf,

              I went trough the links on the sparkmuseum and there is a lot of useful info and interesting pictures of different devices.

              That Froment motor has interesting arrangement. The wheel on right next to the coils seems to be a commutator. And if the coils are like PMHs (I asssume they are) ... that would be a real powerful thing.
              I saw also the other Froment motors and there are also non linear arrangements in some of them. It is a pleasure to watch those pics.

                u shape cores/coils

                HI Lman
                what I really like is all the U cores and U magnets. There are a few i will build the hand crank [looks like G-FIELD]
                I have been redoing fixing mags for hit-miss engines

                  guyzzemf,

                  I am sure you are having fun with the dynamos. I remember lo-o-ong time ago when I was playing with one old hand cranked telephone it was not so easy to crank it and it required some force to be applied with the gears it had. But at the time I was not interested in such a devices. Now it is a good memory.

                  Hope you have seen the big dynamo here http://en.wikipedia.org/wiki/Magneto_(generator)

                    i'd love to have a hand crank ph .the wico mag and titan mag are just like a PMH with points no rotation just make or break the armature

                    every time i zap myself i amazed how strong it is for so little movement

                    i am a licensed airframe @ powerplant . did many mags for small a/c ,but these are way different but kinda the same in how point timing
                    is backwards to [coil bat-points] .I have read everybodys opinion/explanation on PMH it is still something that amazes me

                    THIS IS MY NEXT BUILD

                      I've got an old hand crank phone magneto and also an old Model T Ford coil that both still work. I've had them since I was a kid and I'll be turning 73 next month!

                      Funny story with the phone magneto is when my eldest son (now 44) was only about three years old, he was fascinated with the 120 volt wall outlets in our house. We put covers over them, but he would remove the covers and try to stick in them anything that would fit. We lectured him on the dangers of this and even swatted his bottom a few times for it. But one day I caught him getting ready to stick one of my wife's steel hair pins in an outlet we didn't get covered. The usual lecture wasn't working, so I told him that if he really wanted to know what was in there and what it felt like I could show him. He readily agreed, so out to the shop we went. I hooked a couple of jumper wires to the old telephone generator and had him hold the wires while I gave it a short crank. @#$%^&...... He threw the wires in the air crying, and went running in the house to his mother! That was the last time he ever messed with the outlets, and has a healthy respect for electricity to this day!

                      My grandkids like to play with it now, but I can't talk them into holding the wires like their daddy did when he was little. They like to see how bright they can get a light to go with it and how many volts they can crank under load.

                      I also have an old 1950, KF9, four cylinder Mercury outboard motor that still starts and runs great with it's original Fairbanks-Morse magneto!

                        I am guilty of the same as your son but i got the hairpin in [zap] and dad got zap pulling it out , he was mad

                          Ford Model T Magneto and Coil

                          Hi Guy and Gary,

                          @Guy
                          There are sometimes some hand cranked phones on e-bay going for like 20-50$ if you really want one.
                          On your next build you will have rotating coils ?


                          @Gary
                          I have had not one but several close encounters with 220V as a kid and when somebody would told me that electricity could kill I just did not believe it since I had experienced the electric thrill on my own. Later when I heard that somebody died from being hit by electricity I could not understand how is it possible. I understand now but back then ... I must have been too lucky or having some angel guardians looking after me

                          On the Model T ... when I was reading as much info as I can find about Edward Leedskalnin I was interested to learn more about Model T as he used the magneto from the car for his wheel. And I ran across the following :

                          http://www.youtube.com/watch?v=mOjeVog4A4U
                          http://www.eldensengines.com/Model T...il Tester.html

                          It is the same as used in the car. I just love how it purrs. Notice also how the guy uses only two fingers to rotate it.
                          And there is a patent of the Model T magneto.
                          https://www.google.com/patents/US1098361

                          Some rebuilding job shown here and a wooden model of the Model T Magneto.
                          http://www.mtfca.com/discus/messages...tml?1320869003

                          Plus lots of info on this site.
                          http://www.mtfca.com/books/bookmenu.htm

                          The coil has been patented by Joseph A. Williams in 1914.
                          https://www.google.com/patents/US1092417
                          http://www.mtfca.com/coils/Coils.htm

                          I always thought the ignition coil is Tesla's idea that has been stolen from him. But the Ford Model T coil looks to me more like a Ruhmkorf coil. According to Wiki Ruhmkorf took the idea from another person and he was famous for his Ruhmkorf lamps. Similar to what Tesla was doing later.
                          http://en.wikipedia.org/wiki/Heinrich_Daniel_Ruhmkorff

                          I think people on the forum might find some interesting info in all these links.
