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. The peak starting current is 13 to 26 of full load current. 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. A star delta is used for a cage motor designed to run normally on the delta connected stator winding. Star delta starter can be used only for low to high power three phase induction motors.
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. The power circuit uses to create contact between the motor and three phase power supply. The control circuit uses to control the starter circuit such as on off and tripping operations. The peak starting torque is 33 of full load torque. Star delta starter control circuit diagram. The connection of a three phase induction motor with a star delta starter is shown in the figure below.
