Forward and Reverse Rotation Control Circuit Distribution Box
This video covers the complete wiring diagram, components required, and how the circuit functions to control the forward and reverse rotation of a motor. 🔧 What You'll Learn: ✔ Components and their functions ✔ Detailed wiring process ✔ Safety precautions ✔ Troubleshooting. If a three-phase motor is to be driven in only one direction, and upon its initial energization it is found to be rotating opposite to what is desired, all that is needed is to interchange any two of the three line leads feeding the motor. This can be done at the motor starter or at the motor. The direction of rotation of an industrial three-phase alternating current motor is determined by the applied phase sequence. Let's say a motor rotates clockwise when the phase sequence visible at the motor terminals is L1, L2, and L3. Note : Motor forward circuit (forwardmtr) and Motor reverse circuit.
