An Autotransformer Starter is suitable for both star and delta connected motors. In this method, the starting current is limited by using a three-phase autotransformer to reduce the initial stator applied voltage. The figure below shows the motor with the autotransformer starter: It is provided with a number of tappings. mason phenis indiana
