Abstract: A blower housing comprises first and second blower housing pieces for surrounding a blower fan. The first blower housing piece comprises a blower discharge section comprising an inner tubular portion, an outer tubular portion, and a drain hole. The inner tubular portion defines a blower discharge passage. The inner and outer tubular portions define an exhaust pipe cavity adapted to receive an end margin of an exhaust pipe. The tubular portions are adapted to enable condensate water that forms on the inner surface of the exhaust pipe to flow into the exhaust pipe cavity. The drain hole extends through the outer tubular portion. The drain hole is configured to enable condensate water flowing into the exhaust pipe cavity to drain from the blower housing. The first blower housing piece is a molded one-piece member.

Abstract: A drive circuit for an electric motor includes a variable frequency drive (VFD), a drive contactor, and a controller. The VFD is configured to receive line frequency current from a power source and apply a fixed frequency voltage to convert the line frequency current to a fixed frequency current. The drive contactor is configured to selectively couple the drive circuit to windings of the motor. The controller is configured to monitor for presence of a control signal applied to the drive contactor, wherein presence of the control signal closes the drive contactor to couple the drive circuit to the windings of the electric motor. The controller applies the fixed frequency voltage from the VFD to the windings upon determining presence of the control signal, determines whether the motor is motoring or regenerating after applying the fixed frequency voltage, and gradually increases the fixed frequency voltage applied to the windings when the motor is motoring.

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: A fuse holder for holding a fuse is provided that includes a body, a line side connector supported by the body, and a load side connector supported by the body. The fuse holder also includes a toggle switch supported by the body and capable of toggled engagement in a first position that provides electrical connection. The switch is also capable of toggled engagement in a second position that provides electrical isolation between the line side connector and the load side connector. The fuse holder also includes a fuse carrier. The fuse carrier is supported by the body and adapted for holding the fuse and the fuse carrier is adapted to be removed from the fuse holder. The fuse holder includes a blocking device blocking the toggled engagement of the switch from the second position to the first position when the fuse carrier is not within the fuse holder.

Abstract: A blower systems includes a blower housing, a gasket, and a clamp. The blower housing includes a dilution air inlet port having a tubular portion with an end margin having a plurality of flanges separated by slits enabling flexing of the plurality of flanges to resiliently move radially inwardly from an unflexed position. The gasket extends within the end margin of the dilution air inlet port. The air supply system includes an inlet portion, a combustion air portion, and a one-piece fitting having an inlet, dilution air outlet, and a combustion air outlet. The clamp is positioned radially about the plurality of flanges such that it can secure a source of dilution air within the dilution air inlet port.

Abstract: A method of operating a drive circuit for parallel electric motors is provided. The method includes receiving measurements of stator phase currents in the parallel electric motors. The method includes selecting a target PM motor, from among the parallel electric motors, that generates a largest torque output. The method includes executing a vector control algorithm to generate a complex command voltage vector for the target PM motor. The method includes generating and transmitting a pulse width modulation (PWM) signal based on the complex command voltage vector for controlling an inverter. The method includes operating the inverter according to the PWM signal to supply three-phase alternating current (AC) power to the parallel electric motors.
