Abstract: A method for determining a direction of rotation for an electronically commutated motor (ECM) is described. The motor is configured to rotate a blower and the method comprises rotating the blower using the ECM and determining if the resulting blower rotation is indicative of the desired direction of rotation for the blower.

Abstract: An electric blower system is described. The blower system includes a blower, an airflow system, a sensor, and an electric motor. The electric motor includes a motor controller. The motor controller is configured to operate the motor at a first torque and a first speed to generate a first airflow, determine a first airflow value wherein the first airflow value, the first torque, and the first speed define a first benchmark data point. The motor controller is also configured to operate the motor at a second torque and a second speed to generate a second airflow and determine a second airflow value wherein the second airflow value, the second torque, and the second speed define a second benchmark data point. The motor controller is further configured to generate an operating profile for the blower system defining torque, speed, and airflow points for different system resistances.

Abstract: Electric motors and drive circuits therefor are described herein. The drive circuit is configured to operate in a first mode of operation and a second mode of operation. The drive circuit includes an inverter configured to regulate current to a first winding and a second winding of the electric motor in the first mode of operation and to only the first winding in the second mode of operation. The drive circuit also includes a first switch coupled to the second winding and configured to supply line frequency current to the second winding at a first node in the second mode of operation, and a second switch coupled to the second winding and configured to enable selection of regulating current to the second winding using the inverter in the first mode of operation or supplying the line frequency current directly to the second winding in the second mode of operation.

Abstract: A motor controller for an electric motor is provided, including a drive circuit and a processor. The drive circuit regulates power supplied to a stator of the electric motor to turn a rotor and blower to generate an airflow. The processor receives an air density, an airflow rate demand, and at least one of a measured torque and a measured speed of the electric motor. The processor computes one of a torque set point and a speed set point for the electric motor using an airflow algorithm and based on the air density, the airflow rate demand, and the at least one of the measured torque and the measured speed. The processor controls the drive circuit based on the one of the torque set point and the speed set point to supply electrical power to the electric motor and to operate the blower to generate the airflow.
