영문 초록

Nowadays, EOCR control circuit is a lot of used, but EOCR control of PLC is also used due to development trend of automatic system. EOCR in driving of three-phase induction motor is very important. Main system has to protect motor and control part by blocking main circuit when three-phase induction motor is overload. In this study, we were consideration about stability of EOCR circuit in case of direct EOCR and indirect EOCR(2 type protection method of three-phase induction motor) by using PLC. We did an experiment that direct control of EOCR is surely stable.
