Hi Jack. Im sorry to hear about another failure. This feels just to crazy. But I wont give up. Please don't give up yourself.
Send back the controller and I'll have a look on whats broken and then I'll strengthen it as much as I can to cope with the high
forces of your motor. From the sound of it I get the feeling it's the Back EMF return circuitry that burnt from to much voltage.
Mostly I'm sad that you really needed this controller when the university guys arrive with the dynamometer.

As you have said before, it a hard task to develop a controller to fit a whole new type of motor without being able to test it.
Hopefully I can learn a lot on this failure and then the improved controller will finally work fine.

But I have some questions:
1) How well did the motor run on this minute of operating time?
2) And at what voltage did you run it?
3) Did you hook up 115VAC input voltage or did you use your adjustable powersupplies?

Hello Honk,

Well the motor was up to about 1500 rpm's when the controller burnt up. 
Now do to the wait of the rotors it takes about a ninute and a half to build up to 2000 rpm.
Yes I run it first of the 110 vac line. Then I was going to change it over to the power supplies.
I will not give up on you !!!. I'll send the controller back to you tomorrow.

Thank you for that fast feedback and still having faith in me.

1) But I would also like to know at what output voltage you run the motor?
2) Did it take equally long to build up speed at using the controller as it does using the points only?
    This last question is important as it tells me some of the current requirements I have to handle.
