How to make a Star Delta Start Three Phase Motor Explained in Detail!!

- Star-delta starting is a commonly used method to reduce current peaks at the start of three-phase motors. Let me explain how it works:
High starting current: When a three-phase motor starts, its starting current can be up to 7 times higher than the rated current during normal operation. This can cause problems in the electrical network and affect other connected equipment.
Solution: To avoid this excessive consumption during starting, the motor coils are connected in a star configuration at the beginning, with the voltage in the delta configuration. In this configuration, the coils operate at a lower voltage (around 58% of their nominal voltage) and therefore consume less current.
Transition: Once the motor is spinning, it changes to the delta configuration, where the coils are connected to the rated mains voltage (e.g. 380V). This allows the motor to operate normally with lower current draw.

I'm an electromechanical engineer from ethiopia.I like the way you explain each phenomenon.please if you are happy prepare lecture about controling motors using autotransformer starter.
Very clear presentation, 100%
A very good explanation
Excellent explanation sir thank you very much.
i love the way you present your tutorial. complete with control & power circuit with legends, very very nice presentation. that is a very good way of tutoring.
Thax boss
There is an additional component for the electromagnetic switch, it has a thermal delay switch, that you can set up with a screwdriver. When done, the whole start happens with the press of a button.
Hello, that is what a program that you use.
