Implementation of PLC Based Starting and Direction Control with DC Dynamic Injection Braking for Three Phase Induction Motor

The implementation of forward and reverse direction control system with DC Injection braking for three phase induction motor based on programmable logic controller (PLC) technology is described. The implementation of the hardware with results obtained from tests on induction motor performance is also provided. Experimental results show that the PLC-based control method developed costs less, provides higher accuracy as well as safe and visual environment compared with the classical, the computer systems.
