Abstract: An enclosure system for isolating a conduit enclosure for an explosion proof motor is provided. The enclosure system includes a stator enclosure defining a first enclosure opening. The enclosure system also includes a conduit enclosure coupled to the stator enclosure. The conduit enclosure comprises at least one side wall, a rear wall coupled to the side wall, and an interior cavity. The rear wall defines a first entry port having a first volume. The enclosure system further includes at least one electrical lead. The at least one electrical lead extends through the first enclosure opening, through the first entry port, and into the interior cavity. The at least one electrical lead occupies a portion of the first volume and leaves a remaining volume. The enclosure system also includes sealing compound. The sealing compound is coupled with the first entry port such that substantially all of the remaining volume is occupied.

Abstract: In a one embodiment, a system includes an air conditioning unit having an enclosure, a heat exchanger disposed in the enclosure, and a plurality of louvers coupled to the enclosure. The plurality of louvers is configured to move between an open position and a closed position, and the closed position is configured to protect the heat exchanger from an environment external to the enclosure.

Abstract: A cooling system for rotating machines, such as electric motors, is provided. A heat exchanger housing is coupled with the housing of an electric motor. At least one Peltier effect device is coupled to an outer wall of the heat exchanger housing. At least one outflow air passage and at least one return air passage are defined within the heat exchanger housing to extend between the motor housing and the outer wall of the heat exchanger housing. The at least one outflow air passage transports heated air to the outer wall to facilitate heat transfer from the air to the outer wall. The at least one Peltier effect device facilitates heat transfer from the outer wall.

Abstract: A geared cooling device and method of manufacturing a geared cooling device. The cooling device includes a fan shaft, a fan coupled to the fan shaft and a speed adjuster coupled to a motor shaft of a motor and coupled to the fan shaft. The speed adjuster adjusts a rotational speed of the fan shaft to cause the fan shaft to rotate at a different rotational speed than the motor shaft to facilitate passing cooling air past the motor. The method of manufacturing includes coupling the speed adjuster to the motor shaft and to the fan shaft.

Abstract: A sealing system that self-adjusts according to atmospheric conditions is disclosed. The sealing system includes an annular seal casing mounted on a stationary component, the annular seal casing positioned such that a rotating component extends therethrough, at least one annular sealing agent configured to radially move with respect to the rotating component between a sealed position and an unsealed position, at least one sensor for gathering atmospheric data, and at least one micro-mechanism configured to control the at least one annular sealing agent based on the atmospheric data.
