The new generator no effect counter B. EMF part 2 ( Selfrunning )

[lumen]

This design appears to be somewhere between the Ecklin and Gary designs.

It's a flux switcher like Gary design but also shields in a balanced way like the Ecklin design.

Guys,

Been lurking in the forum the past few days and felt inspired to post an idea. Syair's generator appears to show stationary coils and stationary magnets with moving soft iron between the two, presumably to 'disrupt' the stationary magnetic flux in order that the stationary coils 'see' a moving flux. From the coils relative perspective, it cannot differentiate between a moving magnet and a disrupted field of a stationary magnet - it will develop an output voltage proportional to the rate of flux change and the number of turns.

It ought to be a simple matter to verify such a scheme by constructing something along the following lines - has this (or similar) been done previously?

Yes it was done in the past

They call it a Low Lenz or Lenzless generator:

Dear All.

Gary effect in action !!

Anyone got any ideas how to go auto ??   

Cheers Grum.

Sure. You will never get it to self-loop using a mechanical linkage though, but it would be relatively trivial to set up a drive coil system to replace "Mister Hand" and trigger the coil off of a sensor looking at the see-saw part. It won't take much power either, maybe even something as wimpy as my PerPenduPetulum driver would be enough to tip the balance as you are doing.
You can't feel the force you are putting in with your finger because it's so small, but it's there all right. Try simulating a load, like a generator coil would produce, say by attaching a couple of rubber bands to the rightmost ends of the teeter totter so that the updown motion stretches the bands a little, and you will probably be able to feel the increased drive force necessary to move the shunt plate with your finger.

ETA: I see that people are referring to the part you are moving by hand as a "shield". It's a funny kind of shield though, being a high-permeability piece of transformer iron, that actually works by "sucking in" the field from the magnets. It is actually a magnetic shunt, that channels the field into itself, and makes less of the overall field available to affect the moving see-saw parts when it is in the middle position of its travel. In my way of using language, a "shield" would have zero permeability and would truly keep flux _out_ rather than sucking it in.

Thanks Albator10, for the interesting links; just proves the old saying 'there is nothing new under the sun'!

Cheers,

For a balanced generator there's good example in Muller dynamo in RomeoUK implementation so the wheel was spinning free even there was neodymium magnets involved. Just in this case the moving parts are iron bars which cover both magnetic poles and coil core before reaching opposite magnetic polarity and one of stator disks have magnets instead of coils. It should be not too complicated to build test unit like that for seeing W. Gary magnetic effect in action...
