In my last post i share a star delta starter wiring diagram 3 phase motor connection. Power and control circuit. The star delta wye delta starting method controls whether the lead connections from the motor are configured in a star or delta electrical connection. The phase voltage is lower than line voltage in star connection so the motors or drives connected in star connection runs at lower speed as compared to delta connection. 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. Here will see the practical star delta starter wiring diagram.
