Reduced voltage Starters Circuit diagrams Autotransformer
Circuit diagrams Autotransformer & part winding Autotransformer – HOA 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. By reducing the voltage, the current drawn from the line is reduced during start-up.

Starting Motor With Auto-transformer
Starting Motor With Auto-transformer. An auto-transformer starter makes it possible to start squirrel-cage induction motors with reduced starting current, as the voltage across the motor is reduced during starting. In contrast to the star-delta connection, only three motor leads and terminals are required.
What is Auto transformer Starter? - its Theory - Circuit Globe
Auto transformer Starter. It is provided with a number of tappings. The starter is connected to one particular tapping to obtain the most suitable starting voltage. A double throw switch S is used to connect the auto transformer in the circuit for starting. When the handle H of the switch S in the START position.
Auto transformer starter - Electrical Engineering Centre
Auto transformer starter. This starter produces high efficiency and have the option to be adjusted to obtain the necessary torque and in accordance with the system very efficiency stater but the disadvantage is it very high cost to setup control panel stater. It can improved torque ratio is achieved and starting current is typically 3 times..
