That way a motor can be designed to run at either of two voltages 240 v delta or 415 v star for example. For star delta staterthe motor connection must have 6 cables from control panel and 6 terminals at induction motor u1u2v1v2w1w3to wiring the motor connection for star delta starterthe important thing that we must fully understand is about the basic of star delta magic triangle.

Motor wiring star delta. Wye delta starter wiring diagram sanelijomiddle wire center. 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. If you connect the motor delta and connect it to. Wye start delta run motor wiring diagram collections of great three phase motor wiring diagram 3 star delta and how to wire. 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. A star delta starter is a type of reduced voltage starterwe use it to reduce the starting current of the motor without using any external device or apparatus.
Wiring diagram for star delta motor starter best wiring diagram star. Below is a given table which compares both star and delta connections showing the exact difference between star y and delta δ connections. For three phase motor we use the direct online starter but mostly for small three phase motor. But high load 3 phase motor we use the star delta starter for motor. Comparison between star and delta connections. Wye delta starter wiring diagram sanelijomiddle wire center.
The star delta wye delta starting method controls whether the lead connections from the motor are configured in a star or delta electrical connection. For a given motor the fundamental difference between the star and delta connections is that the rated voltage for the star connection is 1731 x the rated voltage for the delta connection. This is a big advantage of a star delta starter as it typically has around 13 of the inrush current compared to a dol starter. We mostly use the terms star and delta in electrical systems while discussing three phase ac circuits and electric motors. The initial connection should be in the star pattern that results in a reduction of the line voltage by a factor of 13 577 to the motor and the current is reduced.
