An autotransformer starter reduces inrush current by using a transformer in the line just ahead of the motor to step down the voltage applied to the motor terminals. The autotransformer starter is a special type of motor starter that enables the start of squirrel-cage motors using a reduced starting current since the voltage is reduced during the start. Autotransformer schematic diagram Draw the schematic diagram of auto transformer starter.
The autotransformer starter can be used for starting both star and delta connected 3-phase induction motors. This may cause excessive strain on the motor and creates an intense voltage dip. History edit The reduced voltage autotransformer starter or Korndorfer starter 4.
With the use of the transformer the voltage to the motor can be reduced and thus. Auto Transformer Starter3 Cdr. With an autotransformer start a device called a transformer is used.
