On stock armatures coil A needs to be pretty close to coil D. But not touching. This produces the most voltage. Thats what I would expect with a four pole armature. With a 2 pole armature you have more room. Lap wound armatures will operate with as many poles as you want but if you look at the wind...

Eleven turns on the armature, 4 turns on the powered field coil. Don't know for sure on the gen coil. Probably close to a 100 or over. OK so we should have a strong magnetic field, i would expect more volts than you are getting. 3/16 of an inch wide on the comm segments. A little less for the brush...

Input voltage is 25 to 30 and output voltage is 17 to 20? It would be interesting to see a scope shot then we could work out what is happening. How many turns on the armature and the powered field coil and how many on the generator coil? Motor torque is a function of current so speed is also. Voltag...

Hmmmmmm Yes I guess so. Ive tried moving the pickup brushes closer. Wont work. Ive moved them so they touch also. Still wont work. When they are touching you do get some charge going in to the capacitor. Very little, but still a lot of arcing. The motor slows way down when it trying to charge the c...

I have mine set up just like you have explained. You can take the end cap off and it will start and spin it acts like a magnetic bearing. It centers it self. I would not have expected that. Very interesting. The problem right now is trying to collect the spike off the brushes.----------------Youre ...

The main power brush would be probably no. 2. Because it would be positioned over coil D along with coil B and brush No 1. Main thing to remember from my point of view is that wheather brushes no 1 and 2 are on at the same tim or not. If they are then their positions are ok. Other wise no 2 maybe j...

THE wave wound armature is a series wound armature. Again the WAve wound armature is a series wound armature.

Which had significate sparking. That's why they went to a lap wound armature
I believe so

I did rewind 2 armatures. One with the comm connection nearest to the slot the wire was wound through. The other is connected 90 degrees to the winding. I wound mine connected at 90 degrees. Brushes have to be perfectly fit the curvature of the armature. To get the spike to come off the trailing ed...

mbrownn----Some observations from the picture where you numbered the brushes. Numbers 2 and 4 are close together. I suspect they are not in the exact position but you can see they are not separated at 90 degrees. My belief is they are spaced 1 commutator segment away from the brushes that are suppl...

Why the attack? Firstly I built the device and made it run on 3 to 4 volts so what you say is absolutely wrong. The cad was produced later to help people such as you understand it. I am a Mechanical engineer so I do understand what I am doing. You are correct, the device Mr Bedini had was someone el...
