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 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: An EMI filter is described that includes an input having first and second input terminals, and an output having first and second output terminals. A first conductive path is defined between the first input and output terminals, and a second conductive path is defined between the second input and output terminals. The EMI filter also includes a first choke device coupled across the first and second conductive paths, and a first Y capacitor including a first end and a second end opposite the first end, the first end coupled to the first conductive path downstream from the first choke device. The EMI filter further includes a second Y capacitor including a first end and a second end opposite the first end, the first end coupled to the second conductive path downstream from the first choke device, and a second choke device coupled to an inverter output.

Abstract: A motor control system for heating, ventilation, and air conditioning (HVAC) applications is described. The motor control system includes a thermostat and an electronically commutated motor (ECM) coupled to the thermostat. The ECM is configured to retrofit an existing non-ECM electric motor included in an HVAC application and to operate in one of a plurality of HVAC modes. The HVAC modes include at least one of a heating mode, a cooling mode, and a continuous fan mode. The HVAC mode is determined based at least partially on outputs provided by the thermostat.

Abstract: A hydrodynamic bearing assembly includes a first member including a first engaging surface. The first member is stationary in a non-operating mode of the bearing assembly and rotates about an axis in an operational mode of the bearing assembly. The hydrodynamic bearing assembly also includes a second member including a bore and a second engaging surface positioned adjacent the first engaging surface. The second member is stationary in both the non-operating mode and the operational mode of the bearing assembly. The hydrodynamic bearing assembly further includes a spacer member positioned within the bore and is configured to engage the first member to define a first gap between the first engaging surface and the second engaging surface in the non-operational mode.

Abstract: A furnace blower assembly comprising a fan housing, a fan, a motor, and a diverter. The housing defines an interior compartment, at least one air inlet, and a diverter receiving opening adapted to receive a portion of the diverter. The diverter has an air directing ramp and a discharge port. The diverter receiving opening and the diverter are adapted such that at least a portion of the air directing ramp is within the interior compartment of the housing. The air directing ramp is adapted to change direction of air flowing through the diverter receiving opening.
