S-7593 MOTOR UNIT FOR A FLUID PUMP AND METHOD OF OPERATION An enteral nutrition pump system (10) 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 (18) or a fractional rotation of the rotor. Rotor rotation may alternatively be sensed by utilization of magnetic sensors (50) or by monitoring of the AC component of current supplied to a DC motor driving the rotor.
