    Abstract: An electrical circuit for providing electrical energy to an electric motor which operates a liquid pump. The motor and the pump are adapted to be submerged in the liquid which is pumped by the pump. The circuit disclosed herein senses the phase angle between the current and the voltage applied to the electric motor. When the phase angle indicates that the motor is operating without a load, the circuit deenergizes the electric motor. Thus, the motor and the liquid pump are protected against damage. Recognizing that harmonics may exist in the current flow through the motor, the circuit provides for obtaining a filtered signal proportional to the fundamental frequency of the current flowing through the motor. Thus, an accurate measurement of the loading of a motor is obtained. The circuitry of this invention also provides an accurate method of compensation for applied line voltage variations, so that a change in the applied line voltage does not produce a false indication that the motor loading has changed.

    Abstract: A digital phase sequence detector which operates completely independent of signal amplitude values to provide an output signal having a logic level indicative of which of two phasors being compared is leading. The detector develops first and second feedback signals which determine the stable state of the circuit. This feedback arrangement enables the detector to be constructed of standard integrated circuits devoid of flip-flops or other memory elements requiring a clock. The level of the output signal of the detector persists for as long as the relationship being indicated persists, eliminating the need for pulse stretchers, timers, or the like.
