Wiring diagram for auto transformer starter - In contrast to the star delta connection only three motor leads and terminals are required. The starter relay is another switch that is used to control the starting circuit. 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 the start control circuit the relay is connected in series with the battery to shorten the transmission of the large current cable length. Shows the wiring diagram for a full voltage mag netic reversing starter. The voltage that is fed to the autotransformer input is reduced in proportion to the tap setting of autotransformer at the output.
When the reverse contacts r close the motor is connected l1 to t3 l2 to t2 and l3 to t1. This arrangement start an induction motor with reduced voltage and the value of voltage depends upon the ratio of tap selected. Stage 1 at starting auto transformer is star connected by activating star contactor km1 and then the run contactor km2 is closed.
