Muller Dynamo

This is why my thoughts resort to an application that can take advantage of lower voltages and provide the effect effectively.
Using a transformer, low ohm primary, might affect the effect. lol   Some way to convert the output so that we can get 12v or whatever needed. ;] 

I was thinking along the same lines, as this would theoretically be a way to transfer the energy to a line that can handle more resistance.

Has anyone tried a thane heins regenerative acceleration coil setup? on a romero-muller device? where as he load the generator coil acceleration happens rather than decelerate.... just a thought.....

(learning more from you all) keep it up guys!

Hi folks,

i've just achieved speed-up with shorted coil and also with a 'normal' (light bulb) load, at relativ low RPM (~ 1200, sorry no tacho ). And no Lenz, if no acceleration occurs !

That's absolutely cooool ! I've never seen this before.

My setup:
A rotor (12 cm dia.) with 7 NEOs, 20 mm (dia.) x 5 mm thick (N52), NN Arrangement.
6 Coils (1 Motor-Coil, 5 Pick-up Coils)

I've achieved this with a Steel (V2A ?) screw, 45 mm long, 10 mm dia.
3 mm Distance to the Rotor. The speed-up effect occurs with both low inductance, as well with high inductance.
The higher the inductance - the better the acceleration, though.

The Dimensions of my coil bobbins: 36 mm (dia.) x 11 mm (thick), with a 10 mm hole (for audio crossover applications).

(Test) Coil Inductance, Resistance: from 470 uH, 0.8 Ohm (0.6 mm Gauge) to 2.55 mH, 6.55 Ohm (0.3 mm Gauge).


The coil to rotor distance is ~ 25 mm to end of the screw (head).

The solution to achieve OU is (most likely): A Iron Laminat Core !!!

I think, we are very, very close to OU !

Hey all,

I can confirm speedup under load (shorted coil) when using a steel screw similar to what mariuscivic did.

BUT, adding magnets on top of the screw would speed up the rotor even more. And unfortunately this speedup occurs only, if the pickup coil is 40 to 50 mm away from the rotor. At this distance the output is very, very small.

@marius & overschuss: Have you measured generator coil output?

Just some info on a place where you can order mumetal to your specifications.
