The auto-starters (using three autotransformers) can be used to start cage induction motor of the following type

  • Auto-starters using three autotransformers can be used to start both delta connected and star connected cage induction motors.
  • For delta connected motors, the autotransformer starter is used to reduce the voltage applied to the motor during starting, which reduces the inrush current and allows the motor to start smoothly.
  • For star connected motors, the autotransformer starter is used to connect the motor initially in a star configuration with a reduced voltage supply, and then switch it to a delta configuration after the motor has accelerated to the rated speed.
  • This reduces the inrush current and allows the motor to start smoothly.
  • Therefore, auto-starters using three autotransformers can be used for starting both delta connected and star connected cage induction motors.
