dc motor driver

[din noh]

hi everyone !

so...anyone...any interesting circuit to share wit me ?
i'm searching for DC Servo motor driver..
for the controller, i'm using PID controller implemeted as operational amplifier LM741..
help...
tq !

To eliminate useless guessing, can you give us some idea of the voltage and current requirements?

An indication of what will be driving it would be cool too.

I used the L298 for driving the stepper motors in one of my robots so I have some experience with it. Here's some things you might check. Make sure the "sense" outputs (pins 1 and 15) are grounded directly or through a resistor if a current sensing circuit is employed. Make sure you provide a logic level supply to pin 9 (+ 5 v) and do not exceed that voltage on the control inputs. You also need to provide a positive supply to pin 4 of the voltage used to run your motor(s). You can use the logic supply for both if your motors will work adequately on +5v.
