Abstract
A programmable fountain controller for varying the flow rate of an AC PMSM fountain pump in a pre-determined manner so as to generate dynamically changing flow patterns. A micro-controller is provided to vary the pulse width and frequency timing over time for generating signals to an output switching circuit that drives the pump. A mode switch provides user-settable modes of operation selected from a group comprising a programmed flow control mode, a manual flow setting mode, an audio input mode and an external data input/output mode.
