ABSTRACT:
A control for an A.C. motor operates to feed a high average value of voltage to the motor during a starting period of predetermined duration and to then automatically switch the voltage supplied the motor to a lower average voltage of substantially fixed value. This lower value of average voltage is determined without feedback to the control circuit. The control may be designed for use with single phase or multiple phase motors and for motors of various different power ratings.
