  • Method for mitigating bearing failue in an AC induction motor and apparatus therefor
    Patent number: 8247932
    Abstract: A method and apparatus for mitigating bearing failure in an AC induction motor includes installing a high frequency mechanical vibration-absorbing material between various components of the motor. With the vibration-absorbing material in place, the number of premature bearing failures caused by the presence of bearing current is greatly reduced.

  • Apparatus and method for inductive heating a workpiece using an interposed thermal insulating layer
    Publication number: 20080136066
    Abstract: Disclosed herein is an apparatus and method with inductive heating of an electrically conductive workpiece such as a barrel used in molding or extrusion, having a layer of thermal insulation interposed between the induction windings and the workpiece, and using alternating current (AC) at an elevated frequency. Further, variable pitch induction windings may be used to generate a non-uniform and calculated heat input profile, such as to compliment the configuration of a screw for transporting material through the barrel.
