Hi, Dan
Now i use an opamp for constant current control, but
soon I will make a PWM control .
Frequency divider because isnt possible to drive electromagnet with frequency output of plugin...
...it's too high.
Of course, part of informations of the scan , will go down.
Anyway I would be happy to see your system used, for comparison .

Of course.
It's very important to control the damping of coil ,
but isnt only electronic problem ......we have a mechanism.
Bad problem is resonance frequency of mechanism .
The Zobel network can be help, we have all components....
frequency, inductance and moving mass.

@Dan
no..... depends of many factors, including inductance

Hi Dan...
increasing the voltage, the solenoid can work at frequency of osillation more high,
than the feed rate can to be more.
This happens because a coil opposes the current
with increasing frequency. The only way is to increase
the supply voltage.
But the current that circolate in the coil must be adjusted fine, otherwise can burning.

Hi, Tweakie,
currently the power supply is 48v, but I need to improve
the current control on the solenoid coil.
So  I can to increase the voltage power supply to 90v for greater
impact speed at more of 3000mm/m.
This is very important problem, otherwise make a medium/big photo can to be too long
Thanks .

Hi guys,
they are my first tests of my electomagnetic impact engraving.
I have redesigned the solenoid system for to increment feed of execution.
With my electronic I can switch resolution of steps train and I can make small and big photo
I can adjust the power of impact.
With  low resolution can to go to 3000mm/m .
The system is almost ready.
I forgot to thank the forum for the help.
Some tests on granite and alluminium...

Am i that thank you, Tweakie.
I have learned many things to you, about Impact Engraving.
Soon i will show my electromagnetic impact system on granite or metals.
Thanks you.
