Motor control Darlington H-Bridge

This H-bridge allows 4 states for each half [high (1,0) / low (0,1) / high impedence (0,0) / (1,1) illegal state] by controlling the input signal we determine the direction of current in the motor (coil).

Using three not gates, direction control can be achieved using a single input.

Zener diode is for protection when the supply is suddenly taken out during operation .. As the four diodes will not have a path to discharge the coil

Ultra low input current because of the darlington configuration.

Also those half h-bridges can be used to interface any othe type of motors using proper controlling signal

I'd there any way we could include an equilibrium state?

I used an H bridge for my solar tracker an found that it would reach equilibrium when it was balanced

If by equilibrium you mean no voltage difference at the output then yes you can if you removed the three NOT gates you will have the four bases of the transistor as your four inputs and by the right combination of inputs you can control each half of the two halfs separately .. as i said in the description [high (1,0) / low (0,1) / high impedence (0,0) / (1,1) illegal state]
