Muller Dynamo

[chalamadad]

Hey everyone,

I've got my motor running very efficiently. Maybe just a little more than 1 watt input. I am using two fast switching Schottky diodes to collect the oscillation output. I connected the diodes like shown in this thread (thanks to ufopolitics). I am feeding the output to a second driving coil which is creating one spike to just overcome the drag. The second coil is also catching some of the oscillations from the first coil.

Happy with the result. I've made a short video.

@Mr_uu:   I am proposing a system with little heat losses to analyse the "speed under load" effect. This should work. Also, I am very curious if any of the guys decide to combine my method with additional magnets like Romero did. You are right, the next step after finishing the test is the resonance part.


Also - the "single induction coil" per microwave transformer(s group) is safer for the coil. Especially if the coil is made in the Eastern Europe ex-communist block. I draw that picture in a hurry. Thanks for pointing me this. I will remember that when I will start assembling my motor. Anyway, I am afraid my setup will look like a monster generator.

Marius,

Please watch this documentation carefully. That guy explains the setup I am proposing - the high impedance coil (high voltage). There are a lot of formulas on that board, and a lot of different coils are presented - so you do not have to do all the tests by yourself. Please notice the different coils. Here is what you need to have in mind:  high impedance (=high voltage output) coils do not decelerate the rotor. The video is in 5 parts + final setup.

______________________________
high voltage to low voltage reducing transformer with a "gain factor" (for @mr_uu - can this be the resonant stage you asked me to think of?):   Microwave transformers are built in conventional way, and I already pointed that there are some losses inside. Here is the setup I am thinking - I will build it after I finish all my school problems and my induction coils modifications on the dynamo.

Marius, leave this part (transformers) for me. I am not sure about what they say (yet). First I need to study some scientific publications from that PhD guy to get an idea of what he is talking about. You go and prove the speed under load theory - that is the most important part. If you need car induction coils just PM me, but don't try any high voltage coils from TVs or monitors - they are part of special resonating circuits that work with parameters different than a Muller dynamo - extremely high frequencies (kHz). To achieve those many thousands of pulses per second (15625 Hz for the standard television system, higher for video monitors), it means extremely high (and dangerous) thousand of rotations per SECOND in your rotor. You can't do that. Just for curiosity, I managed to push my muller setup to 6000RPM - 100 rotations per second (48 volts for the FET pulsing transistors, 4 pulsing coils, one FET per coil, one Hall sensor per FET and a lot of hall sensor positions tuning). My rotor has 9 magnets, so I got 900 pulses per one collector coil in one second. For those monitor/TV high voltage coils, you need almost to double that speed.

Hi Skaarj

Seemns like lots easier when someone builds a Romero/Muller machine to simply wind the coils with very very thin winds, and lots of turns, so they are HV coils in first place...then run them in series, so even more voltage....then run through spark gap, MOT etc eventually to the load....

[skaarj]

Not really. Just to simply wind lots of turns on coils without separating the layers with insulating greasy paper - it's not enough. Voltage discharges between the layers will happen for sure if you aim to work with tens of thousands of volts. And old automobile coils were manufactured by following all these details. That Tesla guy did not chose to work with high amps and apparently his name is linked with a lot of legends. Since then, everyone avoided high voltage and embraced high amps (and money started to flow). I hope this setup will work.
