masters, can please help me on discussing this circuit?
like: Q1: how does R1 and R2 limits the voltage input ?

Yes. This resistor string ensures the pot has a center position where the motor is off, and an upper speed limit for motor clockwise, and counter clockwise rotation.Q:is there any reasons why the R1=100k and R2=10k resist. are used in this design ?
Your Welcome, and Yes that's right. The operator determines the motor direction by turning the pot and then the window comparators activate the motor driver.really apprreciate your replies,
>so, in other words the op-amps as window/voltage comparators
are the one that acts/dectates what rotation it will go ? (not sure )
