    Abstract: This disclosure provides a consolidated electric motor stator lamination for multiple enclosure types such that a single stator assembly can be used for different classifications of an electric motor. Each layer of the stator lamination includes external features that, when combined with the external features of the other layers in the lamination, can be adapted to conform the electric motor to one of a plurality of enclosure types. The external features include retaining features for one or more covers, fins, and a profile configured to accept cooling tubes. In various embodiments, a single consolidated stator lamination assembly can be adapted to provide a motor having at least two of an open-drip proof (ODP), a totally enclosed fan cooled (TEFC), or a totally enclosed water cooled (TEWC) enclosure classification.

  • Publication number: 20040051279
    Abstract: A mobile elevation chair apparatus includes trapezoidal shaped base that has a periphery defined by front and rear edges and side edges. The base has a lower surface fitted with at least to steerable casters as wheels and an upper surface. The base is wider at the rear edge compared to the front edge so the side edges form an acute angle. A telescoping piston is mounted to the upper surface of the base. A lever enables the piston to be elongated or shortened, the lever extending rearwardly from the piston. A chair is mounted to the top if the piston, the chair having a seat base and a seat back, the seat back portion being mounted to the piston. A plurality of wheels are mounted to the base including the front steerable casters that are mounted to the lower surface of the base at least partially at a position inside the periphery of the base and a pair of rear wheels mounted to the base at a position outside the periphery of the base. A brake mechanism is provided for braking at least one of the wheels.
