Hi again,
Let me quote your original question again here first...
My question is can i prevent the decrease of voltage while limiting my current ? i want my voltage steady or close to being steady..
Thanks in advance...
If you want the voltage to stay at a certain level then you have to
make sure you have enough power to supply the motor to begin with.
If you limit the current, that means you have to use a
'current limiter circuit' (which i assume you have done already)
which, by its very nature, controls current by lowering the voltage.
Thus, there is no way to keep the voltage the same because the
current limit circuits (all of them) limit current by means of lowering
the voltage.
To say this another way, as the circuit kicks in and
starts to limit the current, the circuit forces the voltage to go to
a lower level than it was previously and this is actually what
causes the current to limit. If you dont allow the voltage to go down,
you cannot limit the current. It's as simple as that with a DC motor.
I guess an interesting question would be, why do you want the
voltage to stay the same?
