Abstract: A pump assembly includes a pump housing having a fluid inlet, a fluid outlet, and a fluid channel defined therebetween. The pump assembly also includes an impeller positioned within the fluid channel and configured to channel a fluid between the fluid inlet and the fluid outlet. The pump assembly also includes a motor assembly having a shaft coupled to the rear plate, wherein the shaft defines a first fluid cavity coupled in flow communication with an opening in the rear plate to enable fluid flow into the shaft. The motor assembly also includes a motor housing having a back plate positioned relative to the impeller rear plate to define a second fluid cavity therebetween. The motor assembly further includes a stator assembly coupled to the back plate and positioned opposite the second fluid cavity such that the fluid facilitates cooling the stator assembly.

Abstract: A draft inducer blower assembly for use with a water heater has a housing, a motor, and a fan. The housing has an exhaust volute surrounding the fan and a base adapted to be mounted atop a water heater. The housing has an inlet port adapted to receive exhaust gas from the water heater. The fan is connected to the motor for rotation about a rotation axis. The exhaust volute has a cut-off at a cut-off angle relative to the rotation axis. The exhaust volute has an exhaust outlet passageway that extends to an exhaust port. The exhaust port is lower than the top of the exhaust volute.

Abstract: In one embodiment, a permanent magnet rotor is provided. The permanent magnet rotor includes at least one permanent magnet and a substantially cylindrical rotor core including an outer edge and an inner edge defining a central opening. The rotor core includes a radius R, at least one pole, and at least one radial aperture extending radially though the rotor core from the outer edge to a predetermined depth less than the radius. The at least one radial aperture is configured to receive the at least one permanent magnet. The rotor further includes at least one protrusion extending into the at least one radial aperture, the at least one protrusion positioned substantially along a bottom of the at least one radial aperture and configured to facilitate retention of the at least one permanent magnet within the at least one radial aperture.

Abstract: Described herein is an electric motor assembly for an environmental control system. The electric motor assembly includes a fan configured to rotate to circulate air within a controlled environment chamber of the environmental control system, and an electric motor coupled to the fan and configured to rotate the fan. The electric motor includes a motor controller configured to receive a braking control signal from a sensor associated with the controlled environment chamber. The braking control signal indicates an entrance to the controlled environment chamber is about to be opened. The motor controller is also configured to initiate braking the electric motor in response to receiving the braking control signal.

Abstract: A centrifugal blower assembly includes a scroll wall, a pair of opposing sidewalls, and an adjustable cutoff plate. 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 scroll wall extends circumferentially between a cutoff point to an end point and defines a cutout extending circumferentially from the cutoff point. The scroll wall, the pair of opposing sidewalls, and the cutoff point define a blower outlet. The blower outlet defines a blower outlet area. The adjustable cutoff plate is adjustably positioned within the cutout to define a notch defining a notch area. The notch area and the blower outlet area define a total blower outlet area.

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.
