Controller circuit for Hilden Brandt motor needed..

[Honk]

Thank you for your suggestion.
But you have missed the point of this motor. If he was to use more turns then the inductance would get extremely high and this
would cause him to run the motor at really high voltages, like 500-800 volts, just to push the current through the coils fast enough.

Jack doesn't need to put any more power into the coils than about 2 amps to match the flux from the N48 neos at the chosen
number of turns. Anymore than that could damage the magnets.

At static mode the valves just need 6 volts to reach 2 amps, but when he is running his motor he need to increase the voltage
just to push the current through the coils in the same speed as the motor is running.
You see, a coil takes time to build up its magnetic field. And the higher the inductance, the longer the time.
This is why increasing turns will increase the voltage as well.

Later, in production, the coil windings can be adapted to fit the running voltage desired. This could vary from one situation to another.

Hello Honk,

Thanks for explaining that for me.   I was just about witts end to explain it, you did it real good.

But I have also put it on a prony brake and it tested at around 3/4 HP at 1300 rpm.  Running on 150 vdc at .60 amps.

That is a nice COP of 6.21.
559 watts out / 90 watts in = 6.21 COP
You should have no problems of getting a self-runner out of this motor once the controller is working alright.

Good new year 2008.

This is a great Statement!
Thanks to you ,good guys and energy heros
Best wishes

Actually, that's some of what I wanted to know also. There are things you can do on your own to test this motor besides running it with the controller to see how it runs and what it can and cannot do. You just answered one of them and GREAT! Now have a Super Great Happy New Year 2008 with all the trimmings. Actually, Australia is already feasting. That's why there is never enough beer in the world to go around. lol
