Abstract: A toilet dehumidifier assembly for draining reclaimed water into a toilet tank includes a toilet tank lid that has an opening extending through the toilet lid. The toilet tank lid is positionable on a toilet tank. A dehumidifier is attachable to the toilet tank lid to remove moisture from ambient air surrounding the toilet tank. The dehumidifier is aligned with the opening in the toilet tank lid to drain water into the toilet tank. A container is positionable inside the toilet tank to capture the water drained from the dehumidifier.

Abstract: A permanent magnet motor having a rotor and a stator and configured such that when the leading edge of each pole of the rotor aligns with a stator tooth the trailing edge of that pole is generally not aligned with a stator tooth.

Abstract: According to one embodiment, the present invention provides a motor having a stator core disposed in a motor frame. The stator core is formed of a plurality of substantially identical laminations. Each lamination of the stator core comprises at least one recessed section, which, in cooperation with the frame, defines an incremental segment of closed passageway for routing a fluid along a perimetric surface of the stator core. Accordingly, the closed passageway provides a mechanism by which the outer regions of the stator core may be more effectively cooled. Furthermore, the laminations of the stator core may be oriented at varied orientations with respect to one another to form a labyrinthine path along the surface of the stator core through which coolant is routed.

Abstract: In accordance with exemplary embodiments, the present invention provides a transient power source that includes a flywheel that stores kinetic energy. In the event of a loss of main or operating power, the kinetic energy stored in the flywheel is converted into electrical energy. As one example, the rotation of the flywheel drives a generator that converts this mechanical (i.e., kinetic energy) into electrical energy. Additionally, the exemplary flywheel, as one embodiment, generates a cooling airflow for various components of the electrical machine. Thus, the rotation of the flywheel not only generates power, but also cools the various components of the transient power source as well.

Abstract: In accordance with certain exemplary embodiments, the present technique provides methods and apparatus for providing operating power to a complementary device to an induction device based uninterruptible power source (UPS) via a direct current (dc) bus. In one embodiment, the UPS includes a flywheel that stores kinetic energy during conventional operating conditions, e.g., external power is available. During such operating condition, the external power operates the induction device as an induction motor. However, when external power is lost, i.e., a transient operating condition, power conversion circuitry of the UPS provides ac power to the induction device such that the induction device operates above its synchronous speed and, as such, acts as an induction generator.

Abstract: In accordance with certain exemplary embodiments, the present technique provides methods and apparatus for providing transient and uninterrupted power to protected loads. As one example, the present invention provides an induction device that operates as an induction motor to energize a kinetic energy storage device, such as a flywheel, during conventional operating conditions. However, in the event of a loss of primary power, the induction device, which is fed ac power at variable frequencies, begins to operate as an induction generator. For example, by varying the frequency of the input ac power such that the synchronous speed of the motor is exceeded by the rotating flywheel, the induction device acts as an induction generator and provides a transient operating power to the downstream loads until an auxiliary power source, such as a diesel generator, is brought on line.

Abstract: The present invention relates generally to dissipation of shaft charge. According to an exemplary embodiment, the present invention provides a charge-dissipating device that includes a dissipation member disposed in an explosion-proof enclosure. When mounted to a rotatable shaft of an electric motor, for example, the dissipation member is configured to generally abut against the rotatable shaft. The dissipation member dissipates shaft-charge developed in the rotatable shaft during operation of the motor. By dissipating shaft charge, the likelihood of arcing and/or bearing current (Ib) occurrences are reduced or eliminated. In accordance with another exemplary embodiment, a transmission member is configured to impart a voltage signal onto the shaft.
