Autotransformer starters provide greater starting torque per ampere drawn from the line than any other type of reduced voltage starter.

Question

Quizplus · Accepted Answer

Autotransformer starters use a transformer to reduce the voltage applied to the motor during startup, which allows for higher starting torque per ampere drawn compared to other reduced voltage starters like star-delta or resistor starters.
