Abstract
An enternal nutrition pump system operates in a cyclical manner with a period between cycles being selected in accordance with the desired fluid delivery rate. Each pump cycle may correspond to a single rotation of the rotor or a fractional rotation of the rotor. Rotor rotation may alternatively be sensed by utilization of magnetic sensors or by monitoring of the AC componment of current supplied to a DC motor driving the rotor.
