DO YOU WANT ME TO ASK LUC TO BUILD YOU ONE AND MAIL IT TO YOU?

Thane

I don't know if you meant that genuinly or not, but either way 'yes'.

But it would probably cost more to get it to NZ than it would cost for me to just build, so I'll take a shot but if it fails I might be seriously interested in taking you up on that offer genuine or not since I think you have something here and I really want to explore it.

[aether22]

Thane, I am proceeding to build, one thing though.

I am assuming that you are using 'magnet wire' in your coils?

Not wire with a thick plastic coating?

I'll assume no answer to mean it's magnet wire.

And if you finish your new version before I do and find that a solid rotor doesn't work so well speak up.

One other thing, you could test with a single coil and a variable load and measure the current, see if the magnitude of the effect is linked in a linear way to the current through the coil or not.


Oh BTW EMdevices, not sure if Thane understands your question but I don't, the motor is on the same shaft as the wheel not to one side of it so I can't make sense of your question. Never mind, just got it. you mean front and back not left or right.

Interesting thread and a good read, my sympathies go to groundloop, winding all those toroids with thousands of turns, keep up the good work.

A few tips for groundloop which might save you some effort, removing windings from a toroid, an angle grinder is quick if you need to remove all the coil.

The bitoroid appears very similar to a 3 leg 3 phase transformer and even some saturable reactors, it may be easier to pick up a 3 phase transformer from the local scrap dealer, a 120V one (208V Y) could be run off the mains as the number of turns and peak flux are optimised for this, a variac could be used to adjust the input voltage, load testing is simple as well as things like jug elements can be made into calorimeters giving true RMS power measurement, the watthour meter on the property can be used to measure input power, If you know anybody working for your electicity company it may be easy to get a mains watthour meter (keep magnets away from them) Putting a DC bias on one leg of the transformer will change the permeabilty of that side of the circuit. Also it is easier to get good efficiency from larger transformers due to the copper loss falling off with increasing core area. Japanese transformers tend to be low loss and fairly common as they ship 100V equipment with the appropriate step down transformer for the target market.

aether22,   see this link:   http://www.allaboutcircuits.com/vol_2/chpt_13/12.html     I had a class in electric machines years ago and I remember having the same objections at the time, but it works.  They use them in drills because of the higher torque for the volume, higher speeds etc... 

Link was not working. Why?
this here work:
http://www.allaboutcircuits.com/vol_2/chpt_13/12.html

its shown the same... but first dont work on 3 deifferent PCs
Pese

P.S.
The copied link from EM , is also working now.
The origiune osted from hin: NOT. 
(Not to understand...)

[aether22]

pese, no idea what's going on but his original link worked for me before you mentioned any difficulty and still works.
