  • System and method for vibration severity assessment independently of vibration frequency
    Patent number: 9595179
    Abstract: The method includes receiving a real-time signal containing information pertaining to amplitude and frequency of vibrations of a machine component over a frequency spectrum including a first analysis bandwidth and a second analysis bandwidth, and using the real-time signal to determine values indicative of the severity of vibrations occurring at frequencies in the first analysis bandwidth in a first unit of one of displacement, velocity, and acceleration, and determine values indicative of the severity of vibrations occurring at frequencies in the second analysis bandwidth in a second unit of one of displacement, velocity and acceleration, the second unit being different from the first unit; and associating the determined values in a common unit representing comparable severity of vibrations in the first analysis bandwidth and the second analysis bandwidth.
    Type: Grant

  • Non-intrusive method for extrapolating an internal stator temperature
    Patent number: 7432679
    Abstract: A method for non-intrusive determination of an internal temperature of a given area of an electrical machine stator, comprises obtaining a temperature gradient between an internal wall of the stator and an external wall of the stator, obtaining temperature measurements at locations on the external wall of the stator, and using the temperature gradient and the external temperature measurements to extrapolate corresponding internal temperatures of the stator.
