3 Phase Motor Star Connection

In star connection the line voltage is 3 times of phase voltage. 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 3 phase induction motor consists of a stator which contains 3 phase winding connected to the 3 phase ac supply.

3 phase motor star connection. One is known as star connection and the other one is delta connection. In a three phase circuit there are two types of connections. Comparison between star and delta connections.

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 this article difference between star and delta connection are explained.

The arrangement of the winding is so as to produce a rotating magnetic field. Below is a given table which compares both star and delta connections showing the exact difference between star y and delta d connections. We mostly use the terms star and delta in electrical systems while discussing three phase ac circuits and electric motors.

Line voltage is the voltage between two phases in three phase circuit and phase voltage is the voltage between one phase to the neutral line. Motor starters are types switches either electromechanical or solid state that are designed to start and stop the motors by providing the necessary power to the motor and preventing the motor to draw excess current. Star delta starter y d is a common type of three phase 3 phase induction motor starters generally used in low starting torque motors.

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. The rotor of the induction motor contains cylindrical core with parallel slots that contain conductors. Star connection y system is also known as three phase four wire system 3 phase 4 wire and it is the most preferred system for ac power distribution while for transmission delta connection is generally used.
