Here the circuit diagram of star delta starter explained in detailhere you will learn the connection of star delta starter with three phase motorthe power circuit diagram and control circuit diagram of an automatic star delta starter are explained belowlets understand the star delta starter diagram. A star delta starter is the most commonly used method for the starting of a 3 phase induction motorin star delta starting an induction motor is connected in through a star connection throughout the starting period.

Star delta starter motor connection diagram. The control circuit uses to control the starter circuit such as on off and tripping operations. Then once the motor reaches the required speed the motor is connected in through a delta connection. There is minor correction is require to change printed in boxes sequence of 3 phase wires from w2 v2 u2 to w2 u2 v2 to get delta connection properly. Star delta connection circuit diagram. The power circuit uses to create contact between the motor and three phase power supply. In the diagram of power circuit of star delta starter u2 and v2 of 3 phase motor should be connect to 4 and 6 respectively instead of u2 and v2 are connected to 6 and 4 of delta contector km2.
For three phase motor we use the direct online starter but mostly for small three phase motor. Refer to the below star delta circuit. But high load 3 phase motor we use the star delta starter for motor. This type of starting is suitable for small motors below 5 hp 375 kw. A dual starter connects the motor terminals directly to the power supplyhence the motor is subjected to the full voltage of the power supplyconsequently high starting current flows through the motor. Star delta connection diagram and working principle.
Star delta starters consist of a power circuit and control circuit. Star delta starter wiring diagram this post is about the main wiring connection of three phase motor with star delta starter and control wiring diagram of star delta starter.
