Star Delta Starter Explained - Working Principle

The video tutorial explains the workings of three-phase induction motors, focusing on the creation of a rotating magnetic field using three separate coils. It details the electrical terminal box and the connections for different phases. The tutorial covers the delta and star configurations, explaining how they affect the flow of electricity and the motor's operation. It also discusses the use of contactors to automate the transition between configurations, highlighting the benefits of star delta starters in reducing inrush current and preventing electrical issues. The video concludes with a practical example of voltage and current calculations in both configurations.
