ABSTRACT:
A spray controller includes a governor which limits the current applied to an electric motor that operates a spray system pump. The controller accepts pressure sensing and pressure setting signals and provides a pulse train output to drive the motor whenever the sensor signal indicates that the output pressure is less than the "set" pressure. The governor accepts the spray pressure setting signal and limits the width of the pulse train as a function of the desired pressure setting, thus limiting the motor's current and speed. In the preferred embodiment, the motor's speed is restricted at lower pressure settings, but is allowed to operate at maximum speed at higher pressure settings.
