Forward And Reverse Starter Control Circuit. Forward and reverse motor starter wiring diagram. Forward reverse power circuit they are connected so that under normal conditions one coil will connect l1 with t1 l2 with t2 and l3 with t3.
Forward and reverse motor starter wiring diagram. The same wiring connection is done with the reverse push button switch. Forward reverse power circuit they are connected so that under normal conditions one coil will connect l1 with t1 l2 with t2 and l3 with t3.
Forward reverse control circuit when designing the control schematic for forward reverse circuits we start with the standard three wire circuit add a second normally open pushbutton and add a holding contact branch for the second coil.
Forward reverse power circuit they are connected so that under normal conditions one coil will connect l1 with t1 l2 with t2 and l3 with t3. Now the forward contactor gets supply through phase r off push button r2 forward contactor coil f1 phase y. As soon as forward contactor energized its auxiliary contact f1 becomes normally closed nc from no whereas f2 becomes normally open no from nc. When the alternate coil is energized lines 1 and 3 are interchanged with terminals 1 and 3 allowing for a phase shift in the 3 phase circuit driving the motor and causing it to rotate in the opposite direction.
