Forward Reverse Circuit || Reversible Circuit
When the forward button is pressed, contactor 1 (Forward) will work and the motor will rotate clockwise, but when the reverse button is pressed, contactor 2 (Reverse) will remain off and contactor 1 (Forward) will remain on because the path to contactor 2 is already disconnected by the NC contact on contactor 1 (Forward). Likewise, if the reverse button is pressed, contactor 2 (Reverse) will work and the motor will rotate counterclockwise, and when the forward button is pressed, contactor 1 (Forward) will remain off because the path to contactor 1 has been cut off by the NC contact of contactor 2 and the contactor. 2 (Reverse) still works. When running this circuit, what you need to remember is that when we run the motor to rotate clockwise and then we want to make it rotate anti-clockwise, then never press the reverse button when the motor has not completely stopped from the previous rotation. Because if the motor is still rotating clockwise and then we force it to rotate counterclockwise, then what will happen is a high current spike in the motor. The effect will be that the TOR will trip and make the motorbike stop.
A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting overloads and faults.
On this occasion I will simulate an automatic alternating circuit using a limit switch & timer, why do you have to use a timer so that the transition from forward to reverse can be smooth...
