Star delta starter is a common used in domestic and industry sector to drive variant application such as chiller water pump machinery air compressor and many more equipment. Star delta connection diagram and working principle.

120 4 to a separate. In this tutorial we will show the star delta y δ 3 phase induction ac motor starting method by automatic star delta starter with timer with schematic power control and wiring diagram as well as how star delta starter works and their applications with advantages and disadvantages. Circuit documents 8 19 power supply 8 21 control circuit supply 8 24 contactor markings 8 25 direct on line start of three phase motors 8 26 control circuit devices for direct on line start 8 34 star delta switching of three phase motors 8 35 control circuit devices for star delta starting 8 45 pole changing motors 8 47. Here the circuit diagram of star delta starter explained in detail here you will learn the connection of star delta starter with three phase motor the power circuit diagram and control circuit diagram of an automatic star delta starter are explained below let s understand the star delta starter diagram.

This equipment appliance reduces starting current and starting torque. This is a big advantage of a star delta starter as it typically has around 1 3 of the inrush current compared to a dol starter. 24 24 1 must be connected the control circuit supply is to be connected according 110 110. 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.

A dual starter connects the motor terminals directly to the power supply hence the motor is subjected to the full voltage of the power supply consequently high starting current flows through the motor. Voltage code control circuit the star delta starters are delivered with their control v 50 hz v 60 hz 8 circuit not connected to the power circuit. A star delta starter is a type of reduced voltage starter we use it to reduce the starting current of the motor without using any external device or apparatus. Automatic star delta starter with timer for 3 phase ac motors.

Control circuit control voltage code designed for separate control supply. This type of starting is suitable for small motors below 5 hp 3 75 kw.
