  • Method and apparatus for in situ unbalance and corrective balance determination for a non-vertical axis rotating assembly
    Patent number: 8291764
    Abstract: The invention discloses a novel method and apparatus to determine the degree of residual mass unbalance and a corrective balance solution for a rotating assembly having a non-vertical axis of rotation. When the center of mass of the rotating assembly is not concentric with the axis of rotation, the condition of unbalance exists. When the rotating assembly is driven by a motor or drives a generator, fluctuations in power are produced proportional to the degree of unbalance. The method and apparatus to determine the degree of mass imbalance consists of measuring the average instantaneous real power over an interval of time, calculating the Fourier Transform of the demodulated signal, establishing the peak amplitude and phase associated with the angular velocity of the rotating assembly and calculating the amount of unbalance.
