@Cadman :

Hey, look again at my post, I have edited...see the difference between Manchester and Edison Dynamos related to Stators versus rotor armature config...

Thanks Feb_!!

Awesome!!

It confirms what I was working on!

I guess I posted while you were still adding info to yours.
You're right. It isn't a Manchester. About the coil polarity of the Manchester, I see it the same. It is a consequent pole dynamo. Coil polarities are same at each end, as in both N at the top.

Hello Cadman,

I am sorry but it is NOT the same configuration between Edison type and Manchester...

Edison Types are like a Horseshoe Magnet, they require the two very high towers to build a very strong Magnetic Field.

While the Manchester Dynamo does not require such large Coils Towers, and still Manchester type produces higher power than Edison's.

Finally, I got an image from a book from those times, where it gives us the magnetic field circuit (look in my post above (^) to see it.

Note that in order to get a Full South Pole on top as a Full North Pole below, the circuit must be two parallel coils, where BOTH COILS are pointing a South Up and a North down, in order to Build two South Poles on top and two norths below at the main massive two crossmembers (up and below)

This is very important to differentiate, related to the concept from Figuera we are working on.

Hello Ufo,

About the coil polarity of the Manchester, I see it the same as you do.    Both NN at top and SS at bottom or vice versa.
Apologies for not making myself clear.

Another difference is the Manchester coil core area can be half the Edison core area and still produce the same flux density to the armature, as the core areas add together in the Manchester while the Edison's does not.
