Muller Dynamo

@plengo,  you are messing with my scheme of saving all the pages here as they keep changing and numbers change.     Oh well good riddance to tommy troll. 

Sorry about that  . I am learning how to work with this moderator's new job. It is pretty cool and difficult to be honest with you, but I like it. I am TRYING to keep it clean and focused. May be next time I will only remove the content of the post and leave the link.

I guess one can see how much is not in focus by simply looking the other 2 threads i created trying to be honest to this thread and the members points of view (which are vary valuable).

I am NOT trying to be bias or discriminative at all. So, please guys, be patient with my mistakes as I learn this thing. I really respect everyone's opinions even when they are in way out of line. We learn from each other. Now enough of my own "not in focus".

Today I am building my stators and the stable set. I have the rotor with very good bearings and a 12mm rod. This can handle easily 20000rpm (if it happens). I will be using for the first cut relay coils as I explained on my other thread (Muller for experimentalist). I bought enough to build two machines.

Fausto.

@toranarod: thank you for the instant answer and the educational photo. I just had a look at eBay. It seems one can have Western Digital hard disk drives starting at 15.-- Euro (from Germany). Now I know what to look for.

Do you do anything special for balancing your rotor (besides trying to be precise when placing the magnets)? I guess you turned the rotor with a lathe?

Please excuse my stupid questions. I try to learn how to build a decent mechanical set up.

(I am already looking for an old VCR, because some builders used a rotor from a VCR for mounting a fast turning disk, e.g. in a Bedini motor.)

I have got this encoder plus disk
AVAGO TECHNOLOGIES - AEDB-9140-A14 - ENCODER,3CHANNEL, 500CPR, 5MM+DISK
Farnell Order Code 1161089
and want to use it to control a Muller Generator replication with a TI Launch Pad.

Your PIC schematics for driving a pair of drive coils helps me a lot.

Unfortunately I only got a rather small lathe which only allows to turn objects with a diameter of less than 75 mm (to small for 200 mm disks). But I can turn a good axis with a 5mm end for the encoder disk.

I am double posting this same info over at my forums on the following thread
http://www.overunity.org.uk/showthread.php?1773-MULLER-Generator-free...

Will try to keep both upto date

Well I started and finished the coils today.


The wire that arrived was 7 x 0.250 and not 7 x 0.125


But I wound them anyway and will just have to wind some new ones when the correct wire turns up.

The rig is designed so the coils can be easly swapped out, so not a problem and be good to compare.


Ended up doing 120 turns and each coil came out at 0.8ohms each.


CNC machine is cutting out base plate as I type.
