  • Patent number: 6129952
    Abstract: A system for removing resin from the stator core of a stator of a motor involves means for removing resin (1) from an inner circumferential surface surrounding the bore of the stator core; (2) from the outer circumferential surface of the stator core; and (3) from between the windings along the end surfaces of the stator core. The circumferential surfaces have resin removed from them by moving the surfaces relative to a series of wipers. The wipers push the resin off the surfaces as they sweep the surfaces. Resin is removed from the end surfaces by blowing the resin radially inward, where it either drips off the core or is deposited on the inner circumferential surface, from which it is removed by wipers.

  • Patent number: 6119825
    Abstract: A motor brake apparatus includes an improved torque adjustment mechanism. The adjustment mechanism includes an adjusting nut having a outer ring groove aligned with an inner ring groove defined in a receiving bore of the brake housing structure. A snap ring is located in the aligned grooves to connect the housing structure and adjusting ring while allowing free rotation therebetween. Inner threads of the adjusting nut engage outer threads of a spring pushing element such that rotation of the adjusting nut causes axial movement of the pushing element. The pushing element engages one or more springs which are thereby compressed or released, depending on which axial direction the pushing element is moved. The spring force varied in this manner results in varying levels of braking torque.

  • Patent number: 6116089
    Abstract: A system for detecting defects in a rotating machine system includes a sensor such as an accelerometer coupled to the machine system for detecting vibrations of a rotating element. Output of the accelerometer is transmitted, preferably via a network data link to a monitoring/control circuit. The monitoring/control circuit analyzes the vibration data to develop a normal vibration profile for the machine system during a normal operating phase. The normal vibration profile is stored in a memory circuit for later reference. During subsequent operation of the machine system, the monitoring/control circuit cyclically analyzes vibration data to develop actual vibration profiles. The actual vibration profiles are compared to the normal vibration profile and, where variations between the profiles exceed preset tolerances, the circuit provides an indication of a malfunction or defect in the machine system.

  • Patent number: 6109333
    Abstract: Housing frames for use in electromechanical machines may be advantageously produced using a novel pattern form in a lost foam casting process. The pattern form is made from a cast dissolvable material, and is configured to permit easy modification prior to casting. The pattern form may be adapted to produce footed or footless housing frames, or housing frames of various axial lengths. In addition, the frame area on which a conduit box will be attached can be easily modified prior to casting. After the pattern form has been modified, it is placed in a casting medium of dry particulate material, such as sand. Upon contact with molten metal, the pattern form vaporizes. The molten metal fills the space where the pattern form had been, assuming the desired shape. After the molten metal has cooled to rigidity, the resulting housing frame can be removed from the casting medium.

  • Patent number: 6104269
    Abstract: An X-Y positioning machine has a forcer, with armature coils, that moves around on a platen, supported by an air bearing. Magnets embedded in the motor platen generate a fixed magnetic field with which the armature coils interact. Perpendicular elongated coils interact with the fields of magnets in columns and rows. When a traditional rectangular pattern of the magnets is provided, a packing density and average peak magnetic flux intercepted by the coils are limited to 50%. The present invention provides magnet configurations that provide greater than 50% maximum peak flux density and up to 100% packing density. Several magnet arrangements are provided: a first in which round magnets are used instead of square, and a second in which diamond-shaped magnets are used. The latter can be used at 100% packing density arrangement. In addition to high peak flux density for a narrow coil, these embodiments exhibit low cogging forces. A method of making the magnet is also provided.
