Single-phase motor design to minimize voltage dip

A REDUCTION OF THE VOLTAGE DIPS and light flicker caused by the starting of single-phase motors can be accomplished by decreasing the power component of the starting current or by shifting the starting power factor to a more leading value. Both of these adjustments are made in a new type of capacitor-start motor which causes voltage dips only half as great as are produced by the usual capacitor-start motor. The new motor is larger and employs a new starting circuit with the capacitor in series with the main winding during the starting period.
