  • Publication number: 20100315075
    Abstract: A phase difference type resolver is adapted such that a calculator calculates an angle from a phase difference at a detection-signal zero cross point, determines a velocity at the angle based on an angle calculated from a phase difference at a previous detection-signal zero cross point, calculates an estimated angle at a next detection-signal zero cross point based on the velocity, divides a difference between the estimated angle and the angle into predetermined minimum detection angles, and outputs a real-time signal based on the minimum detection angles in a range after the angle but before the estimated angle.
