RomeroUK Muller generator replication part 1. Muller Dynamo. A search of the internet shows very few replications (2) of the Muller Dynamo.
So why isn't more people building the Muller Dynamo ? Technical Summary The Muller Dynamo is a brushless generator composed of one moving part, the rotor. The rotor is mounted on a shaft, which revolves around inside of the stator shell. Super-magnets are mounted around the periphery of the rotor. Super-magnets are used, one more rotor magnet than generator coils. Amorphous metals are used for the core material inside the coils.
The generator contains an odd-number/even-number configuration of poles/magnets so that a magnetic balance occurs which eliminates the work required to move one pole from the other no matter how large or strong the magnetic surface would be. The rotor of the Muller R&D model contains 16 NdFeB permanent magnets which are set 22.5 degrees apart and the stator contains 15 field coils which are set approximately 24 degrees apart. - Schpankme. Muller generator replication by Romerouk - Page 5. That video does explain the cogging effect real good.
It is easy to genrate 12V with a coil with such a lot of turns. The problem comes in that the coil is 156 Ohms. So the power generated is only about 1W. P=V^2/R= 12 X 12 / 156. Romerouk's coils only had 300 turns litz wire and will probably be much lower in resistance and it will not be easy to get 12v o/p. Setup works with the driving coils in attraction to the magnets If anyone is trying to replicate this please remember to do the testing with the load on and compensate the drag with the magnets on top of the coils Use any number of magnets but make sure that at anyone time you have a magnet in position to compensate the drag created by the coil.Use a motor to drive the rotor and make sure you start testing with a load connected then adjust the magnet up and down to eliminate the drag as much is possible and get best output.
Running without the converter almost killed this generator melting the coils.... Litz wire. Litz wire made out of 8 thinner isolated copper wires Litz wire consists of multiple strands insulated electrically from each other.
Ordinarily the strands are twisted or woven, but no twisting is shown in this diagram. Principle of operation[edit] Litz wire reduces the impact of the skin effect and the proximity effect. Skin effect[edit] The resistance of a conductor at DC (0 Hz) depends on its cross sectional area. For low frequencies, the effect is negligible.
