  • Initial position offset detection apparatus and method for calibrating permanent magnet motors
    Patent number: 10910978
    Abstract: A low cost and efficient method and apparatus for calibrating high performance internal permanent magnet motors that involves starting from an initial estimation of the rotor position and improving the estimation incrementally by successively commanding various current vectors and making adjustments to the estimated initial position according to the rotor's physical reaction to such current vectors.
