TinMan Generator Research Moderated Topic

Lol. Have you measured any output on that? I found that even though the motor sped up,output was not affected until I adjusted the brushes.

wait a bit for the next video

I think we should all examine this patent carefully. It also talks about the amplidyne.
The patent is Robert Alexander's.

It's very close to Tinman's research.

Anyone using 4 poles? Here is the Google link to same patent http://www.google.com/patents/US3913004. looks like I'll be rewinding a rotor today. Any advice appreciated.

Hi everyone,

the below was a post from TinMan at OUR forum on my last video to which I reply by another video and thought it may help clear the air for others here as well.

There is no inductive kickback from the rotor coils of one of these motors,as the coils are all connected-there is never an open circuit for an inductive kickback current to flow out from. What you see as high voltage spikes on the scope is only brush noise/arcing. The coils of the rotor form one big current loop. RF is generated from brush arcing due to high current's,and more so bad brush contact to the rotors armature.
.

I would say this is incorrect,and that your PWM pulses are indeed what is going through to your stator coil. Using your diode setup,capture the output from the rotor diode into a high voltage cap,and see what the voltage climbs to.

Wow ...  I'm surprised of your answer and of how sure you are of it.  Is this really you writing this or have the MIB taken over your account?

In any even, I made a video to demonstrate your suggestion to send the flyback to a cap.

Could you please post a quick schematic of your inductive kickback circuit,as i cannot get anymore than the input voltage out of the brush contacts. The only way i see you getting that sort of voltage out of the rotor is by way of making your rotor coils act as a stepup transformer. For example,if you had 20 turns on your rotor coil,then applying 12 volts,then switching that 12 volts off,you should be able to get around 240 volts out.
Also,please understand that my answer is in relation to you placing more brushes on the rotor to collect the flyback.

Thanks.

@Erfinder I've been researching high voltage low current motors and also the Alexander patent. Any ideas what would those sort of motors be typically found in?
thanks
