Is it the right way to do it, or is there a better way to freewheel the inductive current in such direction reversing setup. Also since it is a 4A motor, what should be the safe current rating that I should assume for the diode.
Operation: At a time only one relay will be activated. So initially If I activate relay 1, then current flows through motor from left to right. But when S1 is opened, and it is halfway in air then current should take this path,
Upward through D1, Left to right through motor, and to ground through S2.
And similarly when Directions are reversed.
