Controller circuit for Hilden Brandt motor needed..

[yorkshireminer]

Dear Jack  and Honk,
it is not just these three, there are lots more here who don't post, or like me, post only when I think I have something to offer, that are cheering you two on. I for one have never doubted your integrity. Perhaps it is because I see such high standards of workmanship from the pair of you that that I automatically assume that you have high moral and ethical standards. I might be wrong but I very much doubt it. If anybody else wants to cast aspersions, then I recommend them to read the Biography of two other great Ohioan inventors whose workmanship is also beyond reproach. They by the way are called the Wright brothers, as decent a pair of Americans as anyone could wish to meet. If you read the book you will understand why.  This year if anyone is interested is the centenary of there invention going mainstream. In 1908 the two brothers demonstrated there invention to the public both in Washington and Le Mans France. For 5 years since 1903 they had been ridiculed as fools and idiots. Just keep at it you pair, you might not hear it but there is a lot of cheering going on.

Deep Regards

Thank you for your encouragement.
I do hope the controller can handle Jacks motor this time.
If his new generator is ready then we will soon have a self runner according
to the numbers publicized. Thumbs Up.

Right now I'm running the controller at 140V output voltage and 120W is going into the valves at simulated 3000RPM.
It's working just fine, so far. I'll attach some pictures and a small avi on the controller running the test valves.

Pic1: Showing the controller setup.
Pic2: Showing the Controller Outputs captured on a oscilloscope. Peak BEMF at 900V.
Pic3: Showing the BEMF recyling. Bursts of 900V BEMF is converted down to the rectified AC input voltage,
WMV: You can watch the controller operating the test valves. The sound is coming from the valves, not the controller.
           Please download the movie "Controller_Running.wmv" at the end of this message.

An update before posting this reply:
The controller have been running the valves for 5 hours now.
No sign of failure yet. I guess I can send it back to Jack tomorrow.
Let us all hope for total success this time around.

Great work!

Be sure to pack the controller very safely before sending it back to Jack!
Who knows for sure what they do with the package while shipping...

I wish the bests for both of you this time!

I wonder sometimes, I have posted pictures and graphics of the motor, I have discussed the coils and magnets, I have discussed the rotor and how it is made.   I think that everyone here knows how to build this motor, I just wonder what I left out.

Hi JackH,

I noticed a couple years back you had a twin motor design (see pic) and now you've went with a single.  How do you compare the performance of the twin to the current motor?
