Both 3 phase 4 wire and 3 phase 3 wire system can be derived in the star connection whereas in delta connection only 3 phase 4 wire system can be derived. Your learning subject what is star delta how to connection star delta what is motor electrical terminal three phase motor electrical supply system caution.
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.

3 phase motor star delta connection. Industrial star delta starter for a 3 phase induction motor a 3 phase induction motor consists of a stator which contains 3 phase winding connected to the 3 phase ac supply. For star delta starter connection we have to give 440v in each of the coil and we know we have three coil so first identify coil by multimeter than give 440v to each of the coil. 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 video we. Below is a given table which compares both star and delta connections showing the exact difference between star y and delta d connections. The arrangement of the winding is so as to produce a rotating magnetic field.
Comparison between star and delta connections. Star delta starter y d is a common type of three phase 3 phase induction motor starters generally used in low starting torque motors. We mostly use the terms star and delta in electrical systems while discussing three phase ac circuits and electric motors.
The amount of insulation required in star connection is low and in delta connection high insulation level is required. Now in the below diagrams three phase motor will rotate in two directions viz forward and reverse.
