Abstract
An apparatus and method for substantially reducing the electrical energy consumption of a.c. induction motor-driven appliances by connecting a database predetermined capacitance in parallel with the motor-driven appliances and connecting a database predetermined inductance in series with the a.c. induction motor-driven appliances to effect the optimal power factor correction and optimal inrush current limiting of such motor-driven appliances thereby conserving electrical energy and reducing electrical energy costs. The databases of the present invention which specify the optimal power factor correction capacitance value and an optimal inductance value for specific a.c. induction motor-driven appliances eliminates the need for preliminary power factor and inrush current related electrical measurements and making the mass production and sale of the present invention practical.
