3 Phase Motor Star Delta Starter Connection. We mostly use the terms star and delta in electrical systems while discussing three phase ac circuits and electric motors. In this video we explain star delta connection in 3 phase motor terminal it is very important topic because we can easily make star delta starter but in mot.
A common wire is taken out from the neutral point which is called neutral while in delta connection the opposite end of three coils is connected together. We mostly use the terms star and delta in electrical systems while discussing three phase ac circuits and electric motors. In star connection the starting or finishing ends of three coils are connected together to form the neutral point.
While keep in mind that star delta starter can only be used for low to medium voltage and light starting torque induction motors.
A star delta starter is the most commonly used method for the stating of 3 phase induction motor. In this video i have explained how to completely wire 3 phase motor with the star delta starter. Now in the below diagrams three phase motor will rotate in two directions viz forward and reverse. Generally we use star delta starters for three phase squirrel cage induction motors that are normally designed to work on a delta connection.
