Wiring Diagram Star Delta Connection Motor
This article is intended to diagrammatically demonstrate the concept of the wiring principle of a star delta wye delta motor control and power circuit when using a PLC Programmable Logic Controller ladder program to control the switching of a 440 volts induction motor..For star delta stater,the motor connection must have 6 cables from control panel and 6 terminals at induction motor U1,U2,V1,V2,W1,W3 .To wiring the motor connection for star delta starter,the important thing that we must fully understand is about the basic of STAR DELTA MAGIC TRIANGLE..This is a starting method that reduces the starting current and starting torque. The device normally consists of three contactors, an overload relay and a timer for setting the time in the star position starting position ..Star delta Y , wye delta starting. Star delta in North America the designation “wye delta” is commonly used instead starting is the simplest method for reducing the starting current of a motor..Sir i have one question is that, my induction motor is also 3 phase. requires 415v volt. 12 terminals are comming out form motor winding.and i want to connect it star delta connection so out of that 12 terminals which should connect to power cable.
