We are using one master and one slave motor. The speed synchronization is done by VFD . For automatic control PLC and HMI are used. We will be programming the PLc in such a way that we can remotely synchronized the motors. As we are using individual drive it will increase capital cost but it will give better and smooth operation and reduces maintenance cost.

We are using one master and one slave motor. The speed synchronization is done by VFD. For automatic control PLC and HMI are used. We will be programming the PLc in such a way that we can remotely synchronized the motors.

Conclusion : From this project we can quickly synchronized master and slave motor. It becomes very helpful in industry as we can operate it remotely by PLC and HMI. This will also reduce time ,money ,human effort. It can also be used in plastic industry, product counting, coal crushing, elevators, oil refineries, drying machines.

Execution of project :
Switch on the main three phase supply. SMPS provide supply to PLC and also VFDs, MOTORs gets started. From HMI we select operation mode and provides rpm of master and slave motor to PLC. HMI is directly link the entered rpm to PLC address. Count are generated according to rpm in plc. If the mode is auto then we have to enter only master rpm. Slave count in auto mode are generated according to master count.
Thus synchronization is done.
