A cartridge fed infusion pump containing a plurality of linear peristaltic pumps. Each pump is powered by a direct current motor. The motor has a shaft which rotates to perform a pump cycle. A position encoder mounted on the shaft is used to determine when the shaft has reached the stop position in the pump cycle. A reverse pulse is used to quickly stop the motor shaft.
