  • Method and apparatus to tune rotor's torsional natural frequency by geometry of rotor winding slot
    Patent number: 6833640
    Abstract: A method and apparatus for tuning the torsional natural frequency of a rotor is disclosed. At least one tuning slot is formed within the winding slots defined by radially projecting winding teeth. The tuning slot extends radially inward from the bottom of the winding slot a distance to tune the rotor to a desired torsional natural frequency. This tuning slot can be positioned preferably at the quadrature axis.
    Type: Grant

  • Method for continuously calibrating an optical vibration sensor
    Patent number: 5146776
    Abstract: An optical vibration sensor is automatically calibrated by extracting a beat frequency vibration signal from a vibration signal produced by the optical vibration sensor, computing a resonant frequency of the optical vibration sensor using the beat frequency which has been extracted, and calibrating the optical vibration sensor based on the resonant frequency computed. The calibration method continuously compensates for changes in the resonant frequency due to temperature and mechanical changes of the optical vibration sensor. The optical vibration sensor is physically attached to an end-winding of an electrical generator.
