Industrial Star Delta Starter for a 3-Phase Induction Motor

During starting, the winding are connected in star configuration and this reduces the voltage across each winding 3. This will reduce the torque by a factor of three. After the delay time the winding are reconfigured as delta and the motor runs normally.

 Industrial Star Delta Starter for a 3-Phase Induction Motor Introduction Of Induction Motor? 

 The most basic feature of an Induction motor is its self starting mechanism. Due to the rotating magnetic field, an  is induced in the rotor, because of which current starts flowing in the rotor.
