Mohamed Hassan Ali Mohamed ^[2] | Dalia Mahmoud ^[9]

Abstract: The objective of this paper is to study and learn how to connect the three phase motor Star / Delta and how to apply the protection of the motor at the start of the high current starter. The three phase motor is conversion to the delta connection by programmable logical control. After converted to the delta connection of the three phases motor continues with the same speed and power. These keeps the motor from damage and ensure its longer operational life.

Keywords: Three Phase Motor, the Programmable Logic Controller, Star/Delta Connection, Overload
