Controller circuit for Hilden Brandt motor needed..

                 Good news, Honk. Do not give up. Keep trying. Victory is made of obstinacy.

Iv'e gotten some new information on the behaviour of the motor.
It seem like there is two types of return voltages.
The ordinary inductive kickback when the valves is turned off.
But there is also a forward voltage that I believe is induced by the rotating rotor core.
It will make the applied 150VDC rise to 475V and this might be the cause of the breakdown.
I will add another diode to prevent this voltage form entering the output voltage line on the controller.
Perhaps this diode will help the controller handle Jacks motor.

@Honk

If those coils in Jacks device are receiving a pulsed DC voltage, is it possible that when the pulse is off, and the rotor is still turning,  that the coil becomes a generator, creating a drive/gen - drive /gen condition. Also if the coils have so much winding, they would become highly inductive enough to supply a discharge at pulse off, much greater then any calculated flyback.

Keep up the good work.

Hi Honk
This might help.. I see this in VFD's "Variable Frequency Drives" in a overhauling load condition...ie it wants to gain rotational speed driving up the DC bus voltage because it has become a generator... or alternator.  I will find the circuit and email it to you that uses a switching transistor and a LOAD to "absorb" the rise. Let me know but I think the acceleration runaway of the rotor is the key and can be exactly what can be utilized.
I'll be in touch

I be following your post, keep the good work, the Jack motor is a great monster for your controller, the problem that I see is that you want to make and efficient and overunity controller,  first try to make a working controller with all the protecction that you can imagine, when the controller work try to make the controller so efficient as you can do it.   

To domesticate this monster first we have to know the working dynamics (voltage, amp)

God bless you with more wisdom.

@all
The Jack motor and the Honk spiral motor are the best projects to have success in overunity in all the internet, also with the right aim, to generate from 3KVA to 10KVA, I believe that this good guys will have success and we most to prepare to give finantial aid from all the world.
