Controller circuit for Hilden Brandt motor needed..

[dingbat]

I had the opportunity to visit Jack and take some voltage measurements on his motor a couple of weeks ago.

The motor is as beautiful as the pictures.  Even more beautiful when it is running.  It runs as smooth as a sewing machine.  I saw the motor run up to over 2000 rpm.  It was running on the points, and a 150vdc power supply.  The motor was drawing about 0.6a according to the meter on the supply.  The motor current would actually drop to that level when some load was applied.  The current was a little higher when the motor was idling.

The purpose of my visit was to measure the voltage on the coils while the motor was running.  I took some measurements and reported them to Honk so he could help identify what is causing the failures in his controller.

The voltage on the coil had some interesting characteristics.  It is a strange beast, ready to be unleashed when the latest controller is ready.

It was very exciting to see the motor running, and I hope that the next controller modifications will work and get this thing going so that power testing can be done.

Great job on the motor, Jack.  I hope I can come down when the controller is running the motor and the power tests are being done.  I was very encouraged by what you showed me.  I think Honk will get it this time, and we might just see the real deal when the motor is power tested.

Good work man.

Did you happen to have a high voltage capacitor with diodes on the power line to catch (and later measure) any fast high voltage flyback that you would not see on a regular meter? Especially with those points that could be acting as spark gaps. Geez, come to think of it, if Honk's circuit will be replacing the points, there is one major variable in there that is still uncertain and still risks causing a problem. Anyways, guys, I am sure you have everything under control and look forward to trial 3, or is it 4, or maybe it's 5, or is it.........lol

I realize that the results of some of what you tested must be proprietary and held tight so I was just wondering. But with 150 volts dc, even at .6 amps, you can get some really serious business going on with those points, coil flyback, etc.

Hey, maybe we should start a "Fly Honk to Jacks Fund" so he could have first hand access to the beast.
