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: An air blower includes a blower housing, impeller fan, and pressure tap. The blower housing defines a blower housing interior and includes a housing wall portion, an air inlet and an air outlet. The impeller fan is positioned within the blower housing interior. A first end of the pressure tap is outside the blower housing interior and a second end is inside the blower housing interior. A through passage extends through a body portion and a base portion. The base portion includes a radius portion extending both from the body portion towards the second end and radially outward from the body portion. The second end of the pressure tap is positioned closer to the impeller fan than the housing wall portion.

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: A motor control system for operating an electric motor is described. The motor control system includes a power supply module disposed external to the electric motor and configured to convert an alternating current (AC) voltage at a first level to a direct current (DC) voltage at a second level lower than a DC-equivalent voltage of the AC voltage at the first level, and a motor control assembly coupled to the electric motor. The motor control assembly includes an input power connector configured to receive the DC voltage at the second level from the power supply module. The motor control assembly also includes an inverter module coupled to the input power connector. The inverter module is configured to convert the DC voltage at the second level to an AC motor voltage to operate the electric motor.

Abstract: A blower assembly includes a centrifugal fan and a motor assembly. The centrifugal fan has a plurality of axially extending impeller blades, a first axial end, and an air inlet. The air inlet is at the first axial end of the centrifugal fan. The motor assembly comprises a stator, a rotor, and an air directing surface. The air directing surface is shaped and configured to direct air drawn into the air inlet radially outwardly toward the impeller blades. The air directing surface extends generally along the rotor axis from its first end to its second end. At least a surface region of the air directing surface generally circumscribes the rotor axis and diverges radially outwardly as such surface region of the air directing surface extends away from the first end toward the second end.

Abstract: A drive circuit for an electric motor includes a first filter, a rectifier, an inverter, and a line contactor. The first filter is configured to be coupled to an AC source and produces a filtered line frequency AC signal. The rectifier is coupled to the filter and produces a DC signal from the filtered line frequency AC signal. The inverter is coupled to the rectifier and produces an AC signal on an output node of the inverter. The AC signal is supplied to the electric motor to energize its stator windings. The line contactor is coupled between an output node of the first filter and the output node of the inverter. The line contactor supplies the output node of the inverter directly with the filtered line frequency AC signal to energize the stator windings when the inverter is disabled.
