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. 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.

Star delta wiring explained. The star delta wye delta starting method controls whether the lead connections from the motor are configured in a star or delta electrical connection. Starwye connection and delta connection are the two different methods which are used for connecting 3 phase system. The wye y configuration as the name suggests is also called the y circuit and sometimes the star circuit. 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. Star connection y delta connection δ in star connection the starting or finishing ends similar ends of three coils are connected together to form the neutral pointa common wire is taken out from the neutral point which is called neutral. However we will look briefly at other colour codes later in the article.
Star delta wiring diagram from the motor control warehouse im going to use the old red yellow blue colour coding for the phases simply because i think its easier to see. A delta circuit is a three wire circuit and a wye circuit can be either a three wire circuit or a four wire circuit. 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. They differ in the way they are interconnected in a particular fashion. Difference between star and delta connection difference between star and delta connection are explained considering various factors like the basic definition of the connections the existence of a neutral point the connection of the terminals the relation between line current and phase current and also between line voltage and phase voltage speed its insulation level number of turns type. In this video well learn in detail about star and delta connection.
In delta connection the opposite ends of three coils are connected togetherin other words the end of each coil is connected with the starting.
