Abstract: A control system for an electric motor configured to drive a fluid-moving apparatus. The control system includes a drive circuit and a processor coupled in communication with the drive circuit. The processor is configured to control the drive circuit to operate the electric motor at a plurality of control values of a control parameter and determine, for each of the plurality of control values, a fluid-flow value and a feedback value, the feedback value corresponding to a feedback parameter, compute a mathematical relationship between fluid-flow rate and one of the control parameter or the feedback parameter, receive a fluid-flow rate demand value, compute an operating setpoint for the control parameter based on the fluid-flow rate demand value and the computed mathematical relationship, and control the drive circuit to operate the electric motor at the operating setpoint.

Abstract: A motor controller for an electric motor is provided. The electric motor is configured to drive a blower to generate an airflow. The motor controller includes a memory and a processor coupled thereto. The memory is configured to store a speed-to-airflow ratio associated with an airflow restriction on the blower. The processor is configured to receive a command for a calibrating airflow and operate the electric motor in a constant airflow mode to generate the calibrating airflow at a calibrating speed. The processor is further configured to write the calibrating speed and the calibrating airflow to the memory as the speed-to-airflow ratio.

Abstract: A motor controller for an electric motor for driving a blower to generate an airflow. The motor controller includes a processor and a drive circuit configured to regulate power supplied to the motor to turn the blower. The processor computes a system resistance for the blower based on a fixed set point for a first control parameter and a feedback parameter. The processor receives an airflow rate demand value and computes an operating set point for a second control parameter based on the system resistance and the airflow rate demand value. The processor controls the drive circuit based on the operating set point to supply electrical power to the electric motor and to operate the blower to generate the airflow.

Abstract: A motor includes a stator comprising windings configured to be energized, and a rotor electromagnetically coupled to the stator and configured to turn relative thereto when the stator is energized. The motor also includes a motor controller configured to measure a speed at which the rotor turns, and energize said stator to generate a first torque output at the rotor when the measured speed is below a first threshold. The motor controller is also configured to energize the stator to generate a second torque output at the rotor when the measured speed is at least the first threshold, wherein the second torque output is greater than the first torque output.
