Autotransformer
Description
  • An autotransformer is utilized to supply reduced voltage to the motor.
  • After a time delay, the autotransformer is shunted out and the motor is connected to full voltage by a closed transition switching sequence.
  • A multi-connection motor is not required. Only three conductors are required between the controller and the motor.
