As you know, Usually we use star delta connections/star delta in three phase induction motor but why?
We use star delta in induction motor because of these following reasons are given below.
- Motor reduce its starting current 3 to 4 times of the direct current and due to which the voltage also drops Hence it cause fewer losses.
- In Star Delta controlling Circuits, Voltage reduces so Current automatically reduce, So the cause of burning of Motor will also reduce.
- In addition, Increase in Starting torque and it prevent motor winding to damage or burn.
