Hello,
i'm trying to design a H-bridge circuit using 2 operational amplifiers. I'd like to drive a DC motor, using a 0V/5V input (at 2.5V the motor should stop). This is my schematic:
And this is the simulation result:
The two probes measure the voltage on the two motor contacts. The DC motor has a 12.3 Ohm winding resistance. I'm finding some difficulties reading the results: will the motor run in both directions? I know, this is not a classic H-bridge scheme: i'd like to use a single supply (+28V), that's why the circuit is a little messy.
Thanks in advance for your help
