Reverse forward star delta starter circuit diagram. In this post you will complete learn about the forward reverse three phase motor controlling starter diagram. Three phase motor connection stardelta y δ reverse and forward with timer power control diagram as we have already shared the starting method of three phase motor by star delta starter with timer circuit power and control circuits. Now in the below diagrams three phase motor will rotate in two directions viz fo. There is minor correction is require to change printed in boxes sequence of 3 phase wires from w2 v2 u2 to w2 u2 v2 to get delta connection properly. The delta configuration for the forward or clockwise motor rotational direction is achieved with the motor configuration u1 v2 l1 v1 w2 l2 w1 u2 l3 which provides a relatively reduced high inrush transient current during the transition period upon switching of the magnetic contactors from star wye to delta motor connection.
