Autotransformer start

The autotransformer start is very similar to the reactor start: both can be adjusted in the supply voltage value and consequently the starting torque.

The autotransformer start type uses the principle of reduced voltage demanding in the motor a reduced current than the current required by a direct start at full voltage.
