Hello FredWalter,

You do not even deserve an answer.

Hello Yorkshire Miner,

This motor generates electricity and add it to the input.   Just ask digbat.    I tryed to explain that to honk, but he would not listen to a thing I said.  Even when he got the scope reading from dingbat he did not beleive it. And then he just guit on the controller, left me hangin.

I'm sorry to hear what you are saying about me. This is not true. I did several controllers to help you out.
And it was initially your own suggestion to let the OSU people build you a controller instead of me, when the last controller burned.

Your letter to me on februari 8 this year. Your own words to quit on the controller quoted in red.

Hello Henrik,

Well BEMF is caused when you turn the power of if a coil,  This is NOT BEMF, when the coil turns off, and the permanent magnets flux lines need to go back through the coil core,
when they do that they cut the coil wires generating electrisity. When the coil turns on, it forces the permanent magnets flux lines to go out of the coil core, cutting the coil
wires again, this is what is creating the 324 volts that is added to the input.  If you do not understand that you might as well quit on the controller, it never will work.

Thanks for your help, it has been greatly appreciated, but I think maybe OSU may have a greater understanding of the motor and more than one engineer to dedicate time to the motor.
And  I'll have OSU build the controller as time is running out on my end of things here due to my failing health.  Once again, thanks for your time and work on this matter.

In my next letter I told you I would like to give it one last try.
But the controller was fried beyond repair beacuse you had replaced the fuse by a piece of metal and I felt I did not have the time at the moment to build you another controller from scratch.
You never replied on my last letter to you, that I had to postpone the controller. I felt this was the right decision as you were going to have another one built by the OSU people.
I was simply not needed any more.

Regarding you blaming me for not listening to you about the voltage feedback. Of course I listened. Every word. But you never had any scope pictures to show me on this.
I never knew what polarity the other voltage feedback you talked about was having. I just tried my best without any real data feedback.
I first saw the scope pictures "drawings" made by dingbat after the last controller was burned.
If I had continued to help you I'm 100% sure I could get it to work, now that I knew it was more than BEMF I had to handle. The controller just needed a blocking diode.

Sorry if you feel abandoned. But if you had replied to me on the last letter about postponing the controller, I might have continued to help you out.

Hi Jack I'm testing the replication right now also with contact points.
If you are willing, would you please describe how you have set this up on your system?
I mean electricly, how did you arrange the cap and perhaps diode to suppress the 'sea of fire'?

Many thanks,
Steven

Hello Steven,

Well I just added , I think 9 feed through caps(25 to 30uf) to the points and then to ground, there was no diode.  The positive I hook to the coil and the other end of the coil was hooked to the points.  The negitive to ground.

If you need a drawing, just tell me and I can draw one and post it here.
