ABSTRACT:
A load responsive, voltage control current for an A.C. inductor motor wherein the power leads of a triac are connected in series with the motor of an alternating current source of power, and the gate of the triac is connected through an inductor to the power lead interconnecting between the motor and MT2 terminal of a triac. Additionally, means are provided to couple a resistance device across the inductor which varies inversely in resistance responsive to a signal which is responsive to motor loading.
