Abstract

A method and system for controlling a rotary pump where a rotary pump can be coupled to a stepper motor, and the stepper motor can be controlled with micro- or nano- stepping accuracy using a processor controlled drive system. The processor controlled drive system moves the stepper motor according to a predetermined move profile; this causes the rotary pump to dispense a precision amount of fluid. The rotary pump can be a peristaltic pump or any other type of pump. The rotary pump can be coupled to the stepper motor through a reduction gear with a reduction ratio of 2:1 or similar. The stepper motor can be mechanically coupled to a rotational position encoder so that a measure of the rotation position can be fed back to the processor. The processor can cause the stepper motor to interpolate between pulse positions of the encoder.
