3ph Motor Star Delta Connection
A timer in star delta starter for a 3 phase motor is intended to do the move from star mode utilizing which the motor runs on a decreased voltage and current and produces less torque to the delta mode indispensible for running the motor at its full power utilizing high voltage and current to transform a high torque.
3ph motor star delta connection. Delta or mesh connection d system is also known as three phase three wire system 3 phase 3 wire and it is the most preferred system for ac power transmission while for distribution star connection is generally used. We mostly use the terms star and delta in electrical systems while discussing three phase ac circuits and electric motors. Your learning subject what is star delta how to connection star delta what is motor electrical terminal three phase motor electrical supply system caution. One is known as star connection and the other one is delta connection.
For detail about star delta stater please read my last. 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 motor terminal connection we have some. A star connection has a common or a star point to which all the three terminals are connected forming a star shape as shown below. Now in the below diagrams three phase motor will rotate in two directions viz forward and reverse.
In a three phase circuit there are two types of connections. Three phase motor connection stardelta y d reverse and forward with timer power control diagram as we have already shared the starting method of three phase motor by star delta starter with timer circuit power and control circuits. In this article difference between star and delta connection are explained.
