Abstract

A control system for an electric motor for a fluid moving apparatus includes a drive circuit and a processor. The drive circuit regulates power supplied to the motor to generate fluid flow. The processor is coupled to the drive circuit and controls the drive circuit to operate the motor at a first speed and torque, and at a second speed and torque, receive a first flow corresponding to the first speed and torque, determine a second flow based on a ratio of the first flow to the first speed, and corresponding to the second speed and torque. The processor is configured to define an algorithm based on the first and second speed, torque, and flow, compute a set point for a demanded flow using the algorithm, and control the drive circuit based on the set point to supply power to the motor and generate the flow.
