After reading the thread posted by "the one" about his newman motor replication i thought id give it a go aswell, im not sure how long you have to wait until you see a voltage drop in your battery?.
Im using a 9v battery wich is about 7.8 volts resting charge, once i hook it up to the motor the voltage drops to 7.1 to 7.3 ive had my motor hooked up all day "10 hours" and about "8 hours" from the previous night and havent noticed a voltage drop...is this normal?.
Im off to bed now so il leave it on tonight and check in the morning to see if there is a voltage drop, the motor is only doing around 120-130 RPM so its not fast by any means but it is holding charge?.
your thoughts/advice?.
PS. i have left a single wire in the positions on the coil of 25% 50% 75% to use for taps!, could you explain how to connect the caps to these so i can further try and improve the efficiency

im still refining my newman motor now shes up and running but i have a question about the RF bursts!.
Am i right in thinking that a portion of the RF burst leaks from the coil and gets disspersed?... or does it only travel within the coil and battery etc?.

Hi Chad,
do it this way:
25% - cap- 50% - cap- 75%
Use 2 x 100 nF to 2 uF foil capacitors with very high voltage ratings.
No electrolyte caps as they could explode.

Thanks stefan,
Has anybody from this forum successfully replicated a newman machine
that is capable of OU or close to it?.

Another update regarding my motor
ive made a few more modifications with the design including the one that stefan kindly told me about and i have managed to get it to drain battery to a lesser degree!, on a typical 24 hour period before the modifications the machine would drain around 1/2 a volt to 1 volt , but now i can get that drain down to "0.01 of a volt" over 24 hour period.
This is using a flat car battery that was around 9 1/2 volts from when i made the modifications,
The motor is currently running between 250 and 300 RPM.
I have a couple more modifications to make wich i believe will improve the efficiancy and hopefully give even better results.
thanks
chad.
