摘要： 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.
摘要翻译：相位差型解算器适于使得计算器根据检测信号零交叉点处的相位差计算角度，基于从先前检测信号零交叉点的相位差计算出的角度来确定角度处的速度根据速度计算出下一个检测信号零交叉点的估计角度，将估计角度与角度之差除以预定的最小检测角度，并根据最小检测角度输出实时信号角度后的范围，但在估计角度之前。
