I tend to agree, but it has to be the first move.If both have no volts then you have to do a bit of head scratching.

Shorted turns in both coils would be unlikely, but you could apply a low ac voltage and measure the current in each coil. Shorted turns don't have much effect on dc resistance but they show up on ac.

Difficult to have any other ideas without actually seeing the thing. Let us know what you find.

""Shorted turns... but they show up on ac.""

I did not know that!
I will add that to the list of things to check.

Thanks,

hook a batt. or batt. charger to the coils in question--then hold a mag in your hand over the coils--is the stringht the same on all three coils--as far as the attraction or repulsion..if theirs a weak one it will have less power [push- pull]..may be shorted windings or shorted to lams..to check to see if its shorted out to lams --just hook up one coil output wire to batt. then touch the other batt. lead to the lams --if theres a short you should see a spark....or just use a ohms meter the same way..

I checked all 3 pairs with an ohm meter and got no reading to the lams. Or to other coil pairs.

When I check AC amps into the coils at low voltage, I'll check DC amps and field strength also.

Flux,
I should have mentioned this is that unusual lay out conversion we talked about a month or 2 ago.
With 6 factory coils and 4 magnets. No cogging. No rewind.
I'll call it a success even if one pair does not work.
Maybe that's why it was in the trash?

I think it would be an excelent beginners project for many reasons.
I will post pic's and the story when it is finished.
Thanks,
G-

Thanks, I have had a look at the original post. There is absolutely no reason why one pair of coils shouldn't work, the whole thing is symmetrical.

If the coils are from the original winding they may be faulty with shorted turns, I assumed that you had wound them recently.

If you prove these coils to be faulty and wish to use it with the 2 good pairs, you will do better to remove the dead coils completely, they will absorb power.

many have tried and failed to make a generator out of a 20" window fan motor.

LOL!
I have to call this my biggest success!
With 0.6A x 3 = 1.8A into a battery.
(thats if the 3rd one works)

Also the least expensive.
Just adding 4 neos, output wire, 3 bridges, solder, and hot glue.
(not sure how good of an idea hot glue is on the coils)

No fancy machining either.
Could buy ALL the tools I used brand new for $12, including the meter!

A little 'outside the box', but kind of an obvious idea after you see a couple pic's.
