    Abstract: Methods and systems for programming an electric motor are provided. An electric motor controller configured to be coupled to an electric motor is configured to control the electric motor to produce torque when direct current (DC) link voltage has up to 100% voltage ripple. The controller includes a first power input, a second power input, and a third power input, an energized line detection device, and a microprocessor. Each power input is configured to receive power from an alternating current (AC) power source. The energized line detection device is configured to sense which power input has received power from the AC power source and output an isolated signal. The microprocessor is coupled downstream from the energized line detection device and is configured to determine an operating profile for the electric motor based on the isolated signal.

    Abstract: According to an embodiment of the invention, a system for managing commands for a pump electric motor for powering a pump for use in a pool and/or a spa is provided. The system includes a user interface for receiving user commands from a user and a pump motor controller for controlling the pump electric motor. The user interface and/or the pump motor controller is adapted to receive first protocol commands utilizing a first protocol from a first input source and adapted to send first input source signals corresponding to the first protocol commands to a portion of the pump motor controller. The user interface and/or the pump motor controller is further adapted to receive second protocol commands utilizing a second protocol from a second input source and adapted to send second input source signals corresponding to the second protocol commands to a portion of the pump motor controller.

    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 blower assembly is configured for use with a gas-operated heater having a burner and an exhaust port. The blower assembly has a blower and a sensor. The blower is configured to operate at two or more speeds and is configured to operatively connect to the burner in a manner to facilitate flow of combustion air into the burner and to facilitate flow of exhaust through the exhaust port. The sensor is configured to be sensitive to pressure of exhaust downstream of the blower. The sensor is operatively connected to the blower in a manner such that the blower will change speeds if said pressure exceeds a threshold pressure.
