Abstract: An electric motor having a snap-together construction without the use of separate fasteners. The construction of the motor removes additive tolerances for a more accurate assembly. The motor is capable of programming and testing after final assembly and can be non-destructively disassembled for repair or modification. The motor is constructed to inhibit the ready entry of water into the motor housing and to limit the effect of any water which manages to enter the housing.

Abstract: A fan assembly includes a shroud attached to a motor housing to prevent negative pressure from developing within the motor housing and prevent moisture from being drawn into drain openings. The assembly includes a fan, a motor, a motor housing, and a fan control. The motor and fan control are disposed within the motor housing. The motor housing includes drain openings to permit the motor housing to be assembled and to permit moisture to drain to the environment from the motor housing. The shroud is attached downstream from the fan such that the drain openings remain open to the environment.

Abstract: A fan assembly includes a vibration damping system to reduce induced vibrational energy generated as a result of fan motor operation. The vibration damping system includes a plurality of arms and damping material. The vibration damping system arms extend between a fan motor housing and a shroud assembly disposed circumferentially outward from the fan motor housing. The damping material is attached to an end of each of the vibration damping system arms and connects each arm to the shroud assembly. The damping material absorbs induced vibrational energy generated by fan motor operation.

Abstract: A refrigeration control system containing a chamber in a fresh food compartment of a refrigerator. In one embodiment, a fan motor is positioned between an evaporator and the chamber. The fan motor speed or torque is adjusted to control the volume of cold evaporator air blown into the chamber. The rate of air flow to the chamber adjusts the temperature of the chamber.

Abstract: A circuit board protection system includes a circuit board including at least one edge, an enclosure used to encapsulate the edge, and a seal. The seal encapsulates the edge and prevents liquid from contacting the edge. Accordingly, the circuit board is protected from liquid infiltration at the edge of the board. Additionally, a method for protecting a circuit board, including at least one edge, in a board enclosure includes applying encapsulating material to at least one of the board enclosure and the edge, and positioning the circuit board in the enclosure such that the edge is encapsulated.
