Complete theory about the contactor. In the power diagram of the forward reverse starter connect the three phase supply to the input of the mcb.
Star Delta Auto Starter With Forward Reverse And Motor Protection
Star delta starter forward and reverse. 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. Output of mcb has to connect with two contactor. Now in the below diagrams three phase motor will rotate in two directions viz forward and reverse. For a star delta starter there is a possibility to place the overload protection in two positions in the line or in the windings. 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. Interlock contacts are also strategically placed on the control circuit as a protective measure.
Change motor rotation for star delta starter. An auxiliary contact from the star contactor brown is connected in series before the two delta contactor coils to isolate both the forward delta coil and the reverse delta coil when the star contactor coil is active. Star delta starter. Three phase motor connection stardelta y 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. Read related article to the forward reverse starter diagram dol starter control diagram. Now in the below diagrams three phase motor will rotate in two directions viz forward and reverse.
We can change the phase of power supply at incoming of main breaker for forward or reverse rotation that connected to mainstar and delta contactorthe important key it is just switch only the phase between red and bluethe yellow phase just remain in the middle position. Can you make a video or lecture on how to connect the motor control circuit lets say dolforward reversewye delta in the motor connection box having 3 leads6 leadsetc. Forward reverse star delta starter control wiring connection diagramstar delta control circuit diagram reverse forward star deltalight bulbelectronicssta. Forward reverse starter power diagram. But we have controlled the direction of rotation of.
