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: An electronic control module is provided. The electronic control module is operably connected to a power supply for providing power to a motor. The electronic control module includes an input device, a processor coupled to the input device, and first and second current supply lines. The processor is configured to generate a command signal in response to an input supplied by the input device and transmit the command signal to the motor. The command signal controls an operating point of the motor. The first and second current supply lines are operably connectable to the motor and the processor. At least one of the current supply lines, the input device and the processor are adapted to utilize the current supply lines both to transmit power to the motor and to transmit the command signal to the motor over the current supply lines.

Abstract: A permanent split capacitor (PSC) motor includes a stator defining an axis of rotation and a rotor disposed adjacent the stator. The stator includes a start winding, a capacitor electrically coupled in series with the start winding, a first plurality of windings, and a second plurality of windings. At least one winding of the first plurality of windings is energized in parallel with at least one winding of the second plurality of windings at a first voltage and in series with the at least one winding of the second plurality of windings at a second voltage. The first and second pluralities of windings are energized to produce a plurality of motor speeds. The rotor rotates relative to the stator about the axis of rotation at a selected one of the plurality of motor speeds induced at least partially by a magnetic output of the windings of the stator.

Abstract: A blower assembly for advancing the flow of air in an air flow device at a selected one of a plurality of air flow rates is provided. The blower assembly includes a blower housing defining a body thereof and a wall of the blower housing moveably secured to the body, a blower wheel rotatably mounted to the blower housing and a motor for rotating the blower wheel at a selected one of a plurality of rotational speeds. The blower assembly further includes a motion device secured to the body and to the wall. The motion device moves the wall relative to the body to a selected one of a plurality of distinct wall positions. The motor rotates the blower wheel at a selected one of a plurality of rotational speeds. A controller calculates optimum wall position and rotational speed to provide for minimal energy usage rate.

Abstract: A centrifugal blower assembly comprises a scroll wall and a pair of opposing sidewalls. The scroll wall is positioned between the pair of opposing sidewalls such that the scroll wall and opposing sidewalls together define a blower chamber and a blower outlet. The blower outlet defines a blower outlet area. An adjustable outlet plate is pivotably coupled to the pair of opposing sidewalls such that the adjustable outlet plate is moveable between a first position to define a first blower outlet area and a second position to define a second blower outlet area.
