Since the motor starting current is greater than the line current with an autotransformer starter the starter produces more torque per ampere of line current than any other type of reduced voltage starter. The transformer steps up the current to make it greater than the line current input during start up.
This conveyor application uses an autotransformer reduced voltage starter. Introduction the theory of applying reduced voltage to a motor to alter the motor torque and power consumption characteristics has existed for many years.
